Hello everyone!
Specs:
GPU: nGeforce 560 TI
MB: MSI z77ag45
CPU: 3770k-i7
Windows 7
CM storm trooper Case
PSU: corsair 750 W
I have been overclocking my GPU and using heaven benchmark. While I managed to get a stable
1087volt (powerlimits not edited, not sure if I should)
950 core mhz
2150 mhz (edited after I got stability at 950)
and temperatures only getting up to 63-64 at fan speed on 75% (Considering a less noisy replacement)
I read the guide on this site which states that the voltage numbers above 1.1 seems to require +/- 400 watt, that does to me sound like a huge power consumption from a 750 watt PSU. Perhaps this is not quite how it works.
Anyway, To me it seems like I can push much harder when my temps stop at 63-64 degrees, and to me it seems that people recommend max voltage tests if you have great temps. For some reason, though, my system just turns to instability when I increase the volt for no specified reason.
Why is it that my tests on 1.15v, since my temperatures are this low, is basically unstable at even just 975 mhz core and stock memory frequency? I see artifacts, a few spikes and stuff right before a crash in heaven benchmark, usually 40-60 second into the test.
Also, is there any way I can break the fan barrier speed at 75%?
Should I touch other parameters to fix this problem, such as the power limits?
Are there problems in general using 1.15v with this card though I can manage to keep my temperatures low?
Thanks!
