Hello all,

Let's try to explain my issue :) 

My graphics card never operates at 100% of its power in game (vsync disabled), 1080p / Ultra ++ in the most demanding games like WD or MLL, or even in benchmark tools meant I suppose, to use the card fully (3dmark Firestrike, 3DMark11, Vantage, benchmark MLL) etc. ..

Except Kombustor, which is the only tool to push the card to its power and temperature limits, every other program aforementioned develop a GPU power between 75% and 82% (approximately 75° temp). The card is on a 1280/2000 OC profile, stable, without throttling, and I enabled the power target to 107% power / 89° temperature in afterburner.

I performed the same tests at stock frequencies after a reset of my afterburner profile (just in case my oc was not stable), and the maximum power achieved is even lower (about 72%). I tested adaptive and maximum power options in the Nvidia control panel, but nothing works. I also tried a reset of 3d application settings in the control panel, but no gain, except 1 or 2 fps more.

So I don't understand, whether I did something wrong, or my card is very lazy :heink: 

Is that behaviour normal ? I suppose the card should reach the power or temperature target in benchmark mentionned above ?

Some details about my specs (BIOS / drivers up to date)
MSI OC 770 gaming 2Gb
I7 4770k @ 4.2GHz
Motherboard Asus Z87-PLUS
16GB 2400MHz RAM Gskill TridentX
Corsair H60
PSU Corsair CX600M
Samsung SSD 840 250gb Evo

Thank you for your help.

The PSU could be the problem.
The Corsair CX series of PSUs uses cheap capacitors that can't output the amount of power they state they can for a long period of time(600W in your case). I would replace the PSU immediately before it damages the GPU.
One guy had the same PSU and the 280X and it died after some intensive gaming.

Antec HCG 620M or XFX Core 650W are my recommendations for the PSUs.
Hope this helps. ;)

Thats actually fairly normal behavior. What temperatures is it hitting under load?

I seriously doubt its the PSU unless its faulty. The thread you linked shows no proof that it had anything to do with the PSU.

Thank you guys.
GPU temperature is about 75° in load (for around 80% power), and CPU temp is around 55°. I also doubt about PSU issue since I play intensive games for more than six months without specific crashes.
@RobCrezz : How could we explain that Kombustor pushes the card to the power and temp targets (107% / 89%) while other benchmarks or ultra gaming develop 82% power / 75° temp ?

What are you using to monitor your GPU usage? If it's MSI Afterburner, then I found out it has a weird tendency to never actually show anything above around 82% usage. Download something like Aida64 or some other utility that can monitor your GPU usage, and use that to check your GPU usage.

Source - I have an MSI GTX 770 as well, and a keyboard with a little display on it that I use to monitor various system statistics. I had the same problem and asked somewhere (probably here) and ended up using Aida64 to monitor my GPU usage in benchmarks or demanding games, in both enviroments, MSI Afterburner would show 82% max usage while Aida64 was showing my GPU usage at 100% in both enviroments. It wasn't Aida reading it wrong, the usage would fluctuate as you would expect by pausing the game, going to a less demanding part of the game etc.

So just check out another utility for monitoring GPU usage, I suggest checking out Aida64, it has a free trial. I personally found it useful enough to purchase it outright.

It depends entirely on the load and where the performance is being limited. Kombuster doesnt hit the memory control at all hardly, but can work the the gpu very hard. Also the power target doesnt always directly correlate to the power usage - You might find even if you keep the power target the same, you can increase the gpu clock and in turn the power usage.

On a normally clocked 770, its fairly normal to see 90-100% GPU usage, but only 80ish% power usage.

Load up the sensor page on GPU-z at the same time and it will tell you what is holding it back from increasing further.

GPU usage is different from GPU power, do you mean GPU power ? I have both metrics in afterburner and GPU usage is effectively around 97-100% in load, while GPU power reaches 82-83% max. (Except in kombustor as I mentionned).

OK thanks, it reassures me :) 
I will check gpu-z sensors this evening and will get back to you.

A good way to see if its running correctly, download and install unigine valley, run at Extreme HD preset and post the score.

Hello RobCrezz,

So I tried Unigine benchmark, on Extrem HD settings, and my score is 2110.
By the way, something strange, the program detected core clock @1330mhz (while gpu was oc @1280mhz in afterburner, confirmed by gpuz or even hwmonitor). So @1330mhz the program crashed o_O

I had to downgrade my core clock @1240mhz in afterburner, to be detected @1291mhz by unigine tool, and pass through the test without crashing.

Other point, my CPU overclocking @4.2ghz has apparently not been detected, as it was mentionned stock frequencies on the result page.

I also checked gpuz sensors, and the only limit which seems to be reached is the GPU usage (at 100%), while GPU power usage still remains at 85% max.

So is everything normal ? Is Kombustor the only tool capable to push the card to its power limt ? BTW, the reason of my topix is a friend, who has a gtx 780 Zotac amp!, which always reaches its power limit in every benchmarks, or even in games. So I wondered why my gtx 770 did not !

Thanks again for your help :)
