Overclocking NVIDIA GeForce GTX 770 ASUS card. Video card. Strange device for overworkers

1 - ASUS GTX770-DC2OC-2GD5 2 - test results. Conclusions display by one page

The newly released GeForce models of the seven series have become the next variations on the GK104 long-liver chip. The most clear changes - grown working frequencies and new GPU Boost. 2.0. All this has led to the increased cooling requirements. That's just the positioning of new products somewhat different - they are originally cheaper. Therefore, instead of strengthening the cooling design, many manufacturers went along the path of simplification to reduce the cost of finite products. The ASUS GTX770-DC2OC-2GD5 map is an example of this approach. If nonsense ASUS GeForce. GTX 680 was equipped with a huge three hundred cooling system, the older version of the GeForce GTX 770 from the same manufacturer is cooled by a simpler cooler previously installed on the GeForce GTX 670 and GeForce GTX 660 Ti. Whether such a replacement has been affected on the final characteristics, we now find out.

Acquaintance with the novelty Let's start with the inspection of the packaging. A large box is done in traditional for asus design.

Supply set:

• power adapters from two PCI-E 6 PIN on PCI-E 8 PIN;
• disk with software;
• instruction.

Externally, the video adapter really does not resemble the ASUS GTX680-DC2O-2GD5 and other relatives of the old series, but it looks like GTX670-DC2T-2GD5 and other modifications of GeForce GTX 670. But only looks like, because the fee is more difficult.

The adapter of the two-plate version of the DirectCu II cooler is cooled. Top thermal tubes appear on the side. Zone above video connections are covered with a metal "visor".

The reverse side of the map is completely covered with a perforated plate. This structural element gives rigidity, preventing the deformation of the textolite under the weight of the cooler. But as a radiator, as it would be possible to think initially, this plate does not protrude. A dielectric film is even applied to the inner surface.

On a small open area there is a contact group for implementing hardware monitoring and monitoring VGA Hotwire parameters when connecting via these graphics cards to ASUS ROG system boards.

A set of interface connectors Standard: DisplayPort, HDMI and two DVIs.

The cooler has three thick thermal tubes, which, bending, permeate the array of thin aluminum plates, tightly fitted to each other. Thanks to the technology of direct contact, the surface of the tubes is directly in contact with the surface of the crystal, which ensures the most efficient heat removal.

The design is well familiar to us by asus cards GTX 670/660. There are no changes.

From above on the radiator, a metal casing with a pair of fans FIRSTD FD7010H12S with a diameter of 80 mm is screwed. On the background of MSI N770 TF 2GD5 / OC with a pair of 100-mm fans, this solution is certainly modest.

Your radiator also has the power components of the power node.

On the design of the board, in contrast to cooling, did not save. We have a copy of the old ASUS flagships - GTX680-DC2O-2GD5 and GTX680-DC2T-2GD5.

An octa phase GPU voltage converter is implemented running the DIGI + ASP1212 controller. The memory power supply uses two phases. Power is connected to six and eight-to-contact connectors.

GK104-425-A2 graphic chip is surrounded by a protective frame.

Two gigabytes of memory are scored by eight Samsung K4G20325FD-FC28 chips.

At the moment, GTX770-DC2OC-2GD5 is the top version of the GeForce GTX 770 from ASUS. This suggests increased working frequencies. However, the factory overclocking is very modest. The core base frequency is raised from the recommended 1045 MHz to 1059 MHz at Boost Clock 1111 MHz. The memory at all cost without frequency correction and functions with an effective value of 7010 MHz.

The GPU-Z utility appreciated the ASIC Quality parameter of 79.9%.

The real GPU frequency in Boost mode all the time kept at the level of 1150 MHz. In the heavy graphic test, Unigine Valley Benchmark, the kernel temperature did not exceed 76 ° C at 25 ° C in the room. The result is good, if you remember that the reference GeForce GTX 680 normal operating temperature is 81 ° C. And here the working frequencies are higher, and the heating is less.
The newly considered video adapter MSI N770 TF 2GD5 / OC was colder only a few degrees. But MSI has another important advantage - low fan speeds. ASUS rotation speed reaches 2800 rpm. This is a lot. We have repeatedly noted a quiet instrument of FIRSTD fans in ASUS products. Therefore, the outcome level of noise can still be assessed as an average due to the soft character of the sound.

In simple games, the card is heated for a pair of degrees less, and the speed of the fans is below about 100 rpm. This is clearly visible on the load schedule in Grid 2.

Disperse graphic processor It was up to 1267 MHz in Boost with a basic value of 1189 MHz. Memory stably earned 8074 MHz. This is higher than the results of the mentioned video adapter MSI N770 TF 2GD5 / OC. In general, the result of GPU is not recorded. Among the GeForce GTX 680, we came across models with higher indicators. But in terms of memory frequencies, representatives of the six hundred series is definitely weaker.

For such a regime, we increased the turnover of blowing fans to a maximum, which led to even greater noise. So the practical implementation of the entire acceleration potential without replacing the cooling will be impossible.

Characteristics of tested video cards

The considered video adapter is comparable to the reference GeForce GTX 780 (results only for nominal frequencies). Due to the features of the functioning of the updated Boost and the direct frequency limits from the temperatures for this video adapter, an additional run is added in almost all test applications. This is done to reduce the effect of the first run, which gives a higher average result due to the fact that the kernel does not have time to warm up and is functioning at higher frequencies for some time. After entering the middle operating temperature There is stabilization and frequency.

Separate comment should be given according to the usual GeForce GTX 770, which is the role of the considered asus. According to the results of studying the reviews of real reference samples and, given the features of the functioning of GPU Boost 2.0, we have a little updated the frequency configuration for our "standard GTX 770". The new boost works more aggressively due to a higher power limit. In fact, the frequency reduction is now primarily on temperature. A powerful cooling from GTX 780 / Titan and on GTX 770 should easily provide a temperature within the framework of the specified restrictions at 79 ° C. Therefore, testing of reference samples show that the real frequencies of the Boost with a base value of 1045 MHz are close to 1137 MHz. Although during operation inside the housing, heating can be greater, and the frequencies are below. Therefore, we chose a fixed value of 1110 MHz.

Honor AMD Protect Radeon HD 7970 and Radeon HD 7970 GHz Edition. Note that our version of GHz Edition is obtained from a simple Radeon HD 7970 by setting a fixed frequency of Boost mode. That is, instead of a floating frequency variant in the range of 1000-1050, we have a video adapter with an unchanged value of 1050 MHz. Also added the younger models NVIDIA - GeForce GTX 760 and GeForce GTX 670.

Technical data Test participants are shown in the bottom table. For GeForce, the official data on Boost Clock is indicated. The graph shows a full range of the core frequency, including briefly achieved peak values.

Test results

Asus Map Faster than reference by 2-3% in. The usual GeForce GTX 770 is faster than the older Radeon by about 10%. Acceleration speeds up ASUS by 11%, the advantage over AMD's competitor is preserved. Increased frequency allows you to minimize the difference with GeForce GTX 780.

In GeForce GTX 770, a small advantage over the Radeon HD 7970 GHz Edition only on average FPS. When overclocking between rivals parity. Assign fully GeForce GTX 780 fails, the main backlog is at the minimum FPS.

The usual GeForce GTX 770 demonstrates the advantage of 12-14% relative to the older Radeon. At Asus. additional advantage at 2%. When accepted the hero of our review again comes on the heels of GeForce GTX 780, but it cannot be fully compared to the flagship.

The difference between the usual GeForce GTX 770 and Radeon HD 7970 GHz Edition is 2-7%. The advantage of ASUS over the reference is only a couple of percent. Acceleration speeds up a video adapter by 11%, a small advantage over Radeon is saved.

The game is optimized for AMD solutions, and here for the first time the dispersed Radeon HD 7970 slightly bypass GeForce GTX 780. Simple GeForce GTX 770 is inferior to 13-15% NVIDIA flagship and 4-6% does not reach Radeon Ghz Edition. Factory overclocking provides ASUS minimal backlog from AMD competitor.

The last part of Hitman also belongs to the category of games optimized under aMD video card. Here both GeForce GTX 770 are a bit inferior even a simple version of the Radeon HD 7970. The lag GeForce GTX 770 from GeForce GTX 780 just over 21% and overclocking this gap does not compensate.

In the game, we will consider the test results by the built-in test (level D6) and when measuring the frequency during the passage of a small episode of the "ashiste" level. In the first case, the minimum FPS is not taken into account due to a large scattering of this parameter in the native benchmark and a large dependence of it from the CPU power.

Without PhysX, the advantage of GeForce GTX 770 over the older Radeon is minimal. When overclocking ASUS, it turns onto the performance level of GeForce GTX 780. Turning on TESSFX technology slightly increases the separation of AMD solutions. Upon minimal FPS, simple GeForce GTX 770 is already at the lowest Radeon level. A more significant advantage of NVIDIA junior solutions and GeForce GTX 780.

In a newer 3DMark, the positions of competitors NVIDIA and AMD are changing. This time the ASUS GTX 770 is weaker Radeon HD 7970 GHz Edition by 6%.

conclusions

ASUS GTX770-DC2OC-2GD5 offers a combination of the top versions of GeForce GTX 680 and cooling from GeForce GTX 670. The GeForce GTX 770 video adapter is in a cheaper product in comparison with the old flagship, so the manufacturer is forced to reduce the cost of its production. So partial savings from ASUS is quite clear, and it is not the only one that comes in this way. As a result, we have good overclocking, decent temperature indicators, but unsatisfactory noise level. The video card in the category of the most noisy still does not fall, but also in the category of a quiet way ordered. With this cooling, it will not be possible to realize all the frequency potential, no matter how good it is. Even in the denomination, the demanding user will resort to manual settingsTo lower the fan speed slightly. A positive point is that a certain amount of efficiency in a cooler for such an operation is still available. Although the results would be significantly better with a more familiar three-shaft cooler. So the attractiveness of this solution will depend on the final value. The video card may become good choice For overclocking lovers, the adept of a quiet computer will find more interesting alternative solutions.

Test results

Alien: Isolation

In Alien: Isolation, you can talk about the equality of Radeon R9 280x and GeForce GTX 770 - the first participant is better at the minimum FPS, the second percentage faster in the average frame rate. The perforce GTX 780 GeForce GTX 770 is striking over GeForce GTX 770. The advantage of palit over the reference to 7%. Acceleration allows you to win another 6-7%.

Assassin's Creed: Unity

GeForce GTX 780 and RADEON R9 290 with a noticeable margin bypassing younger members. GeForce GTX 770 wins 16-22% at the rapid video adapter based on TaHiti - Radeon HD 7970 GHz Edition. Loge from the senior representative of NVIDIA at the level of 35-37%. Such a huge difference can be partly connected with the insufficient memory of the younger member. At the same time, there is a modest increase in performance when increasing the frequencies of the GeForce GTX 770, which does not prevent the confident leadership regarding the nearest AMD competitors.

Battlefield 4.

In Battlefield 4, GeForce GTX 770 is a meager treated over the Radeon R9 280x, and Palit JetStream wins 3% over the average FPS with Radeon HD 7970 GHz Edition. The lag from the GeForce GTX 780 at the level of 11-14%, which is easily compensated by increasing operating frequencies from GeForce GTX 770. Our instance of the Radeon HD 7970 when acceleration turns out to be a bit faster than the forced Palit.

Call of Duty: Advanced Warfare

One and a half percent loses GeForce GTX 770 old Radeon HD 7970 in Advanced Warfare. Palit is faster than a fear of 5-7% and a couple of percent weaker Radeon R9 280X. Completely meager lag of Palit from GeForce GTX 780. In the acceleration of the RADEON R9 280x, 14-16% wins at the forced GeForce GTX 770. The last at frequencies 1185-1293 / 7938 MHz is comparable to the Radeon HD 7970 GHz Edition.

Crysis 3.

Powerful positions from GeForce GTX 770 in Crysis 3 shooter. Rapping from Radeon R9 290 at the level of 8-12%, the separation from the top version of the Radeon HD 7970 is 13-16%. RADEON R9 280X with significant acceleration barely reaching a competitor in denominations. Palit GTX 770 Jetstream is 7% faster than reference and almost not inferior to GeForce GTX 780.

Dead Rising 3

In Dead Rising 3, about one level are GeForce GTX 770 video cards, Radeon R9 285 and Radeon HD 7970. The advantage of Palit over the standard counterfeit up to 7% with a 4-6% lag from RADEON R9 280x. With acceleration, Palit does not reach the Radeon HD 7970 GHz Edition level in a par, although the frequency increase minimizes the difference between them. It should also be noted that the decent indicators of the video card with two gigabytes were demonstrated only with medium quality textures. For high quality Significant braces began, bringing some participants outside the level of acceptable performance.

Far Cry 4.

For example AMD Radeon. R9 285 and Radeon HD 7970 is clearly visible the difference between the graphic solutions for two and three gigabytes. With two gigabytes there are essential FPS drawdors. NVIDIA has such a large rupture, and the results of GeForce GTX 770 as a whole are good. This middle frequency participant slightly overtakes the Radeon HD 7970 GHz Edition, and at the minimum slightly inferior to the simple Radeon HD 7970. Palit with its factory overclocking bypassing the GeForce GTX 780 in the average, but the minimum loses. When overclocking the GeForce GTX 770 and RADEON R9 280X, the second wins only on the minimum FPS, and then a bit. It can be concluded that if you have a double memory capacity, the advantage of GeForce GTX 770 above solutions based on GPU Tahiti would be unconditional.

As a supplement, we decided to compare productivity in more severe MSAA 4X smoothing mode, when using video memory rises.

Completely unexpectedly RADEON R9 280x and Radeon HD 7970 lose their advantages over minimal FPS over GeForce GTX 770. The latter occupies an average position between the amended AMD solutions. Palit with its advantage of 5-8% is almost not inferior to Radeon HD 7970 GHz Edition. Increased frequency allows JetStream to build up the power by another 4-8%.

Lords of the Fallen

It is worth noting the unusual situation with performance on different cards. For younger Radeon, each new download led to a decrease in FPS relative to the first launch, and GeForce has increased frequency of frames. Only on the cards with 3-4 GB, stable results were observed.

NVIDIA graphic solutions dominate the game Lords of the Fallen. GeForce GTX 770 comparable with RADEON R9 290 by minimal FPS. Radeon HD 7970 GHZ EDITION is up to 23%. Palit is a faster than the usual fellow by 6% when lagging from GeForce GTX 780 in 2%.

Metro: Last Light

According to the results of the built-in test Metro: Last Light simple GeForce GTX 770 bypassing the older version of the Radeon HD 7970 with a meager advantage. Acceleration makes it possible to increase the performance relative to the reference frequencies up to 12%, thereby win half apler at GeForce GTX 780.

According to the results of testing at the level of "ashes", the advantage of the GeForce GTX 770 over the Radeon HD 7970 GHz Edition becomes more explicit - from 1% to 5%. In acceleration, Palit is again comparable to GeForce GTX 780, and at the minimum FPS - even with Radeon R9 290.

The game is tested on the "ash region" and in the third mode, with the active effects of PhysX.

AMD video cards in this mode show a good middle frame rate, but at the time of the imaging effects of PhysX, prepayments are possible below 30 FPS. The performance of the GeForce smooth, without sudden drops. In this case, the overall level of FPS is very high even on a simple versions of GeForce GTX 770.

Middle-Earth: Shadow of Mordor

Middle-Earth: Shadow of Mordor is known for its stiff memory requirements. Even with high quality textures (instead of Ultra), no less than three gigabytes are recommended. A huge gap for minimal FPS between RADEON R9 285 and Radeon HD 7970 such recommendations visually confirms. Between GeForce GTX 770 and GeForce GTX 780, the difference is less, but the increase in the minimum FPS with increasing frequencies is completely meager. And according to this parameter, the GeForce GTX 770 loses Radeon HD 7970. With a larger memory, GeForce could be eaten otherwise.

Ryse: Son Of Rome

In the most severe smoothing mode, the Thief benchmark will use up to 2.2 GB of memory, but this is enough to lead to rare, but significant FPS prepires. Large gap for minimal fps graphic maps 3 GB from 2 GB comrades. And although the GeForce GTX 770 for the average frame rate is not inferior to the Radeon HD 7970 GHz Edition, the minimum parameter loses about 70%. In reality, everything is not as bad and on GeForce can be played without substantial discomfort. If you lower the quality of SSAA, then you can forget about the drop in productivity at all.

Watch Dogs.

There is no sharp difference between average and minimal FPS in Watch Dogs, although the game at ultra-quality also requires three gigabytes. According to the average parameter GeForce GTX 770 better Radeon HD 7970 GHz Edition, and at the minimum slightly bypasses simple Radeon HD 7970. The Palit advantage over the usual counterclaim to 7%, the increase from overclocking 3-9%. Increased frequency reduction from GeForce GTX 780 to a minimum. The leader is Radeon R9 290.

GeForce GTX 770 has a middle position between the Radeon HD 7970 GHz Edition and Radeon R9 290. Palit is 8% better than the fellow and 10% weaker than the senior GeForce GTX 780.

RADEON R9 280X 2% better than GeForce GTX 770. Palit Jetstream is 1% more productive Radeon HD 7970 GHz Edition. Palit acceleration gives an increase relative to reference frequencies to 13%.

Energy consumption

A little unexpectedly looks like a large power consumption of GeForce GTX 770 with regard to the senior GeForce GTX 780. The cause is in the floating frequency of the latter, which is sharply reduced when the temperature limit is exceeded. With acceleration, GeForce GTX 780 is able to demonstrate much greater readings. The factory parameters of the Palit speaking and the role of the reference version of the GeForce GTX 770, also have an impact on the final picture. The general level of energy consumption in solutions on the GK104 and Tahiti in the face value is close. In the radeon acceleration, the most voracious, which is associated with a significant increase in the voltage, which is necessary for high frequencies.

conclusions

According to the results of testing in the opposition of GeForce GTX 770 and Radeon R9 280x out of 16 test applications for AMD, a victory in seven (given thief) remains, and the representative of NVIDIA wins in six tests (taking into account the meager gap in Battlefield 4). In the remaining games (Alien: Isolation, Far Cry 4 and Watch Dogs), you can talk about a certain parity - Radeon wins a little over the minimal FPS, and GeForce on average. When overclocked for the AMD member, the victory in 10 applications, let them go somewhere and with a minimum separation. Well, it is worth considering that the results in acceleration will depend on the potential of each individual instance. The question of choice finally dispels the comparison of the price tags. RADEON R9 280X is cheaper, which automatically makes this card with the best acquisition. To overpay for GeForce GTX 770 makes sense if you want to play games with PhysX. Without video card NVIDIA Get sharp drawdown FPS (Metro: Last Light) or the complete absence of some special visual effects as Turbulence particles system in Lords of the Fallen. A competitor has a different counterproof in the form of the Mantle API, which allows you to raise performance on systems with not a particularly powerful processor (Battlefield 4, Thief, Dragon Age: Inquisition).

At the time of the predecessors in the face of GeForce GTX 680 and Radeon HD 7970, NVIDIA positions were clearly stronger than in the case of the current GeForce GTX 770 and Radeon R9 280x. Modern games operate in large amounts of data, which increases the requirements for the memory volume and tire bandwidth. In some cases, it is clearly seen how the GeForce GTX 770 potential is not disclosed because of two gigabytes - Shadow of Mordor, Thief. And in other cases you can see the negative impact of insufficient memory, albeit at a much smaller scale. All this can be compensated by small edits of graphic settings in each game menu. But if you buy now GeForce GTX 770 with a prospect of long use, it is better to take a video card for four gigabytes. This version should be more interesting and more productive RADEON R9 280X. Although with a light-up to the price of such models, you can think about the acquisition of GeForce GTX 780.

The Palit GeForce GTX 770 Jetstream considered in this article offers a standard amount of memory with a substantial factory dispersion of the kernel. Operating temperatures and noise levels. Acid potential above average. Against the background of the previously tested GeForce GTX 680/770, this card looks very worthy and good. If its price arranges, then Palit Jetstream will be a pleasant acquisition.

As it was promised earlier, pleased to present an advanced review and Test of the Palit GeForce GTX 770 Jetstream 2048 MB. It features the factory overclocking of the core and the original cooling system. Whether all this is the pleasure of overpayment in the amount of $ 25, we learn during comprehensive testing.

The output of the 700 series into the market is a big soil for disputes like NVIDIA fans and amd camp adherents. This is due to the fact that the company did not go to the full update of the filling and nucleus, but on cosmetic update and rebranding.
That is, in the face of GeForce GTX 770, the buyer receives the actual already familiar GTX 680. And the top GTX 780 according to unofficial data is only a rejection in the production of NVIDIA GTX TITAN. Oils in the fire added today's news to the ready-to-make market to the market with a GTX 760 marking hiding inside GTX 670. Anyway, but the situation is currently such. In justification, you can only say that the price tag is not very different from the predecessors from the 600 series. That is, for comparable cost, you can take a fresh version of execution with similar filling, but more productive.

If in the case when GTX 670-GTX 680-GTX 690 video cards are already installed in the system, the appropriateness of the update is under a big question, then when assembling new system Or when making a decision to update from 500 (and below), the series will already be justified by selecting proposals from the 700 series. Palit in turn has proven itself to russian market And rightfully gets much attention from buyers. And this is not surprising: thanks to the pricing policy, the video card of this manufacturer is beneficial to stand out among competitors, and besides, it is worth adding the quality of performance and assembly, the result becomes obvious.

In general, the cause of the closure in the camcorder market is the economic crisis and the overall downturn in the volume of sales in the desktop market. Yes, and that hide, in the game segment, too, everything is far from ideal, modern games have ceased to be the engine of progress, and also a growing segment of free online games with low system requirements is of great popularity. It is in this background that AMD and NVIDIA and began to be engaged in modernization instead of another development cycle.

Within the framework of this test, a full range of measurements of performance and performance of the Palit GeForce GTX 770 Jetstream 2048 MB will be carried out. BUT consolidated tables Results will be more interesting in doubly, since there are already fresh data on and. The difference in the data you can see clearly.

Accessibility Palit GeForce GTX 770 JetStream 2048 MB

At the time of test, the average cost, according to Yandex.Market, is 14 140 rubles. On the basis of the same adapter available: Reference Palit GeForce GTX 770 1046MHz PCI-E 3.0 2048 MB (13 840 rubles), as well as a similar JetStream with 4 GB of memory. The difference in the cost between the reference and overclocked with the original cooling is minimal, and has to choose in favor of the representative of the JetStream series.

From competitors I will note: MSI GeForce GTX 770 1098MHz PCI-E 3.0 2048MB (18 135 rubles), Gigabyte GeForce GTX 770 1137MHz PCI-E 3.0 2048MB (15 663 руб.), (16 332 руб.).

For comparison, it is worth noting: Gigabyte GeForce GTX 680 1071MHz PCI-E 3.0 2048MB (16 065 rub.), Palit GeForce GTX 680 1084MHz PCI-E 3.0 2048MB (16 051 руб.), MSI GeForce GTX 680 1110MHz PCI-E 3.0 2048MB (17 587 rub.).

Complete set Palit GeForce GTX 770 JetStream 2048 MB

The Palit GeForce GTX 770 JetStream 2048 MB video card is supplied in the traditional Jetstream solid packaging line. On the color design and placement of information blocks and images, it does not differ from the previously considered Palit Jetstream.

The video card itself is hidden in a separate box inside the main packaging with a folding lid.

In addition to the video card itself, there are: PCI-Express Power Cable, HDMI-DVI, HDMI-DVI, Disk Drivers, Instructions and Case Sticker.

The equipment is very good.

Appearance Palit GeForce GTX 770 Jetstream 2048 MB

The main distinguishing feature of the Palit GeForce GTX 770 Jetstream 2048 MB is the original cooling system. It uses a massive cooler with a plastic casing and three fans.

The size of the cooling system is greater than the size of the width and length. A similar approach is a bit strange, although in practice the engineers were guided by the minimization of noise from the "impact" of the air flow into the plastic casing. The increase in dimensions will complicate compatibility with a computer case. Jetstream is not the only long card on the market, and not the longest. The question is rather to the body than to the map.

After installing the video card occupies three slots at once in the system unit.

The Palit GeForce GTX 770 JetStream 2048 MB has two SLI connector, if you wish, you can create a tandem of four video cards. But whether it will be possible to place such a quantity in the body, a big question due to a height of three expansion slots.

The video card itself Palit GeForce GTX 770 Jetstream 2048 MB is built on black pCB from pCI-Express Tire 3.0.

On the back of the board there is a block for stress measurement.

Food is organized from tandem 8- and 6-pin connections. For comparison on the reference GTX 680 there are two 6-pin. The video card can consume up to 300 watts.

On the rear panel Released: Two DVI, HDMI 1.4A and DisplayPort. To one video card you can connect up to three monitors at the same time.

Cooler Palit GeForce GTX 770 Jetstream 2048 MB

The average fan has a larger size compared to extreme, and also distinguishes lED backlight. Also in this part of the casing has a visual difference and large dimensions. In general, such an execution of the casing seems more interesting than the smoothed forms among previously considered Palit Jetstream.

The fans have changed the shape of the blades, they are a little curved relative to the axis. Profiled blades increase air pressure while maintaining the speed of rotation.

The plastic cover is hidden: a copper base with direct contact, copper tubes and two blocks of aluminum radiators. It is cooled not only the GPU, but also memory with VRM.

Filling Palit GeForce GTX 770 Jetstream 2048 MB

Palit GeForce GTX 770 Jetstream 2048 MB is based on the already familiar Kepler GPU architecture. The 28-nm GK104 GPU chip is used, exactly the same as the GTX 680, the same architecturally, but updated audit. The kernel has 1536cuda with TDP170 W.

The kernel itself GK104 KEPLER with a 256-bit bus is already acquainted with pain, including solutions with 2 GB of memory and alternative 4 GB GDDR5. In GTX 770, the working frequency of memory up to 7 GHz with a capacity of 224 GB / s was raised, but the same tire remains at the heart. The core base frequency is at 1046 MHz, in the Palit GeForce GTX 770 Jetstream 2048 MB it is overclocked to 1150 MHz. The power controller is implemented using onsemi NCP4206, you can forget about monitoring, the same solution is used in gTX video cards Titan and GTX 780.

Chips are used sAMSUNG memory K4G20325FD-FC28, this memory Different with higher efficient frequencies.

Testing Palit GeForce GTX 770 JetStream 2048 MB

It's time to see what is capable of Palit GeForce GTX 770 Jetstream 2048 MB. According to the adopted method, we conduct an assessment of the efficiency of the cooling system, an assessment of energy consumption and productivity in games and synthetic tests. It will already be a third video card test with a visual display of the operation of the test video card in games.

1. Temperature mode of video card
The cooling system used has shown itself better than the reference, the temperature level is lower.

2. Noise
If the temperature level is little concerned about the PC private user, then the noise is more important and feel during operation. Measurements are carried out in two modes: a simple and load at a distance of 50 cm from the video card. The cooling system used showed itself perfectly, the video card is not heard even during the full load of the GPU, the noise level changes only by 1 dB.

3. Power consumption
Thanks to the lower level of the kernel operating frequency compared to GTX 680, the level of energy consumption has become less, but when it has become expected above, but very close to GTX 680 data. On average, energy consumption is approximately 200 watts. When installing one video card, Palit GeForce GTX 770 JetStream 2048 MB will require a power supply of at least 550 watts, with a tandem from 750 watts and higher. It is better when choosing a power supply with a power supply, this will make the system more stable.

Overclocking Palit GeForce GTX 770 JetStream 2048 MB

Via utilities MSI Afterburner managed to raise the core frequency to 1205 MHz, and the memory up to 7714 MHz. The frequency of rotation of the fans and the voltage did not change. The overclocking level is approximately similar to the percentage ratio obtained on GK104 in the percentage, the union overgrown level is higher.

(Left - manual acceleration, right - factory overclocking)

Overclocking manipulations were reflected in the FPS level, in the tables above the results in a number of games used to verify stability, marked in the field - Palit GeForce GTX 770 OC Jetstream. In Battlefield 3 Grocery - 8fps, Hitman Absolution - 2fps.
At the same time, the noise level remained at the same height, and the temperature rose only to 1 degree in the full load mode.

Video Overview Palit GeForce GTX 770 Jetstream 2048 MB

Results by Palit GeForce GTX 770 JetStream 2048 MB

Palit GeForce GTX 770 JetStream 2048 MB showed itself as balanced ratio cost / performance solution. Summing up, I note the advantages: low cost, low noise, high overclocking potential, good equipment and opportunities. Of the minuses, there is a dimensional cooler. The result of the test becomes well-deserved award: "Gold..

The cooling system used was already familiar to us earlier and showed itself well. Still, the height often can determine the choice in favor of a particular solution. The final buyer is essentially without the difference of kernel temperatures within 5-10 degrees.

In general, overall impression From testing GeForce GTX 770 remained positive, but in the presence of a productive video card, the update will not give weighty gains. But when assembling a new system, new items are quite interesting. From AMD, there is still no worthy competitor, the same Radeon HD 7970 is less productive and also more expensive.

If you are wondering how to neglect the video card, you exactly hit the address.

Most gamers with the release of each new game are faced with such negative phenomenon as a decrease in FPS indicators.

The reason for this phenomenon is known - specifications Video cards do not meet the requirements of the running game.

Consider the basic principles of overclocking video cards and consider the acceleration process in practice.

Note!Regardless of the method and level of overclocking, work on elevated, compared to factory, frequencies leads to a reduction in the video card service and even to failure.

Theoretically, the breakdown as a result of overclocking is not warranty cases therefore thoroughly think about the feasibility of holding such an event.

Overclocking principles

1. High frequencies can be achieved by increasing the voltage on the kernel and memory chips, therefore the load on the computer power supply is increasing, and the need for cooling is increasing with an increase in the load.

Therefore, it is necessary to ask your power reserve.

2. It is necessary to establish a special software that allows you to control the temperature of the PC components, not only.

After that, measure the heat dissipation of all components before the overclocking operation.

3. An increase in the voltage directly proportionately increase the heat dissipation, so in advance you should take care of the video card cooling system.

Overclockers accelerating video cards for sports interest use liquid nitrogen for these purposes.

In most cases, in practice, liquid cooling is used, since the noise level is increasing when using air cooling and the quality is inferior.

4. Increasing the frequency must be made gradually and step by step. Step rate equals 5-15% of the original frequency of the video card.

Important! After each frequency increases, you should run a test or game and testing at least half an hour. If during this time the game or test does not hang and there are no artifacts - distortion of the picture, twitching the image, ripples, flashing - can be increased frequency.

All the actions described above should be repeated until the signs are not stable workAfter their detection, you should return to the previous step and perform the test.

Overclocking methods

Software (software) acceleration. This type of acceleration is carried out with the help of special utilities, some of them are included with video card drivers.

This method is more secure, rather than acceleration by flashing.

The most common overclocks for overclocking :, PowerStrip, GeForcetweaker, Atitools, TNTedit, TNTCLK.

Refracting BIOS video cards.

This type of overclocking is to replace the standard video card BIOS to edited, overclocked BIOS for the same model or BIOS older model.

Tip!This type of overclocking is quite dangerous, so do not advise you to engage this type Dispersal of beginners and people with curves.

Acceleration of GEFORCE NVIDIA video cards

Initially, overclocking procedures need to know the frequency of the graphics core, memory and shader blocks.

GPU Clock (graphic core frequency) - 783 MHz.

Memory (frequency of the video card) - 902 MHz.

Shader (chader block frequency) - 1566.

To change these parameters, we will use free utility Nvidia Inspector. This utility does not require installation and after downloading is enough to run it.

In the lower right corner of the program, press the "Show Overclocking" button, and in the next window, confirm the opening of additional parameters.

Before us overclocking the video card:

Run the Shader Clock parameter by 15% of the base frequency, moving the slider to the right to the value of 1800 MHz.

Please note that following it, the GPU Clock parameter is also raised.

To confirm the changes, click the "Apply Clocks & Voltage" button. Before proceeding with an increase in the memory of the video card, you should test the changed parameters.

It can be done by running any capacious graphic application (for example, one of the games) or special program For test test (for example,).

Important! During the test, it is unforgettable to monitor the temperature of the video card. If the temperature exceeds 90 ° C, you should stop the test and reduce the parameters that have been changed, after which it is re-test.

If everything is in order, open the NVIDIA Inspector program and increase the memory frequency by moving the slider in the MemoryClock field. Confirm the changes.

We again test the video card for stable operation.

For stable work, Vienecartes on new, higher frequencies, we recommend slightly increase the supply voltage of the video card (the "Voltage" field).

In our case, the voltage was increased from 1.075 V to 1.125 V.

We run CPU-Z and watch performance indicators: PixelfillRate (pixel sketch speed) 6.3 GPIXEL / S - 7.2 GPIXEL / S, TextureFillRate (Speed \u200b\u200bSpeed \u200b\u200bSpeed) 25.1 GTEXEL / S - 28,8 GTEXEL / S, Bandwitch 57.7 GB / S - 66.4 GB / S.

In this case, we deal with linear addiction - Increased frequencies by 15% gave 15% performance increase.

Note! NVIDIA Inspector allows you to save settings in configuration file. (Button "Create Clocks SHORCUT"), which is created on the desktop.

To change the video card when starting a computer, it is necessary to copy the created file to the startup folder.

Acceleration video cards ati radeon

The next mark for overclocking was the frequency of 1200 MHz, but after passing a number of tests it became clear that the work at this frequency is the limit of the work of this video card (artifacts began to appear in games).

An increase in voltage to 1.25V did not bring the expected results, and the VRM value came close to critical 95 ° C.

It was decided to return to the previous frontier of 1,100 MHz, since refining modes at this frequency practically do not differ from the standard operation mode and the risk to overload the video card is minimal.

As a result of overclocking, we received a 25% increase for the following performance indicators: PixelfillRate (pixel sketch speed) 28.8 GPIXEL / S - 35.2 GPIXEL / S, TextureFillRate (texture sketch speed) 100.8 GTEXEL / S - 123.2 GTEXEL / s.

Theoretical bandwidth Memory tires (bandwitch) remained unchanged at 240 GB / S.
