Ok, just about the temps of this thing.
After doing some F@H benchmarks for temps CPU was getting to 78/79 degrees C
. Too high for me @ stock. This was being caused by an over zealous auto voltage setting in the bios which randomly occured. I have not been able to replicate its effects since. CPU was using up to 1.3V, and was idling at 56 degrees averaged. It would not ramp down.
This was fixed by loading bios defaults and defaults in Gigabytes EasyTune 6. (Handy program that is).
I originally thought it was being caused by a combination of Load line calibration and the Auto CPU Vcore. After trying all 6 combinations of Auto, disabled and enabled for LLC and Auto and Normal for Vcore, nothing had changed. All I had learnt was that LLC causes a complete PC freeze in both occasions when set to enabled.
Now to lower the load temps. Tried some things in bios, didnt change anything. Then I tried playing with the Dynamic Vcore settings to lower the CPU voltage which was always high. Minimum was 0.88V, load was 1.2-1.3.
After slowly lowering the dynamic voltage by 0.05V increments down to -0.200V all was good with great temp drops and stability. I tried for -0.2500V but this caused a no boot and freeze at the windows load logo, same for -0.24375.
Both -0.225 and 0.2125 caused blue screens shortly after booting into windows.
This leaves me where I am currently at -0.20625V.
The i5-760 minimum voltage is reported to be 0.65V. Using CPUID HWMonitor Pro, the minimum CPU voltage is now reported at 0.67V
. Value running F@H on all cores at 100% is 0.96V. Maximum recorded voltage during boot was 1.07V. So now the CPU almost loads at the old idle voltage.
Temps are mow maxxed at 65-66 degrees. Ambient is 32-33. Thats loading at 33 degrees above ambient.
I did not get to this low voltage last night around midnight before bed and the temps then were around 2 degrees hotter whereas ambient would have been at least 10 degrees cooler.
I think this is a great effort and achievement in dropping the temps with the hardware Im using. How bout you guys?
Im much more comfortable with 65 degrees over 79
Edit: back to -0.2000V for stability. Runs @ same temps.Edited by MrGMcD - 2/13/11 at 6:22pm
