Thread: HD 5770 overclocking?

Hello everybody!

I wonder if it would be "profitable" to overclock my HD5770?
I never overclock anything, could you explain to me quickly?

Thank you.

I tried only with CCC: 895/1335

With the benchmark short farcry 2:
AA4x-in 1920x1080 and all high: of 39.50Fps to 41.90fps
Temperature-5mn benchmark: 62 ° C
Fan speed 5 minutes: 75%!

Perf level and temperature is average I think you it can someone advise me better?

Its pointless to go too much RAM, mounts over the GPU and less RAM, it will be more efficient. 950/1250 test and if it happens not just the voltage increases. Once the voltage surge, you may be 1000/1250 attempt, then it will be better.

Ok, as much for me, because when you know it and we see that the card brand new to the 65/70 ° C with a "participation rate" is 87%, its scary! I recognize a more pleasant fluidity Farcry 2.

Réctifiquation first display problem after a few minutes of testing (10min farcry has donf, and 5 minutes from metro 2033 DX11). I launched Total War, and there was the display that started buger I therefore returned to the office and told me that CCC GPU utilization to 97%!

Following the little bug in the games I rebooted the PC and restart the desktop everything worked while the virus runs and hit a bug! Lines, square and weird colors etc. pc unusable! Tell me there are ways to retrieve the base frequencies in the BIOS and can say that it was only a big fright!

I touched nothing has the 5770.

No one to help me with my problem?

I increase the values of 20 (gpu and ram) under FurMark 20min test pass with a 71 ° C max Xtreme burning with the tower open but when I restart a few seconds after entering my password is a bug huge display, full color, black screen and pc unusable!

How does your fan speed can vary so much? me my fan not exceed the 45% is a Sapphire HD 5770 at 900/1400 MHz without increasing the voltage and I not exceed 70 degrees Celsius on crysis.

Well I have not done any benchmark test but so far no blem.

In terms of overclocking the HD 5770 is not a lightning war, and performance varies very little. I advise instead to add a second HD 5770 in Crossfire. That's what I did, and it sends the steak.

980 for 1.2?!

Trials like 930-940 @ stock voltage AC will heat much less for a fall of perf not great. I noticed that to pass certain frequency you have to go hard on the vGPU.
