Hi all,
I have been trying to OC my 970 for a couple of days now and have had trouble getting it stable. I have looked at guides and how to's for help but have had no success. I have tried many combinations of CPU-NB, NB and CPU voltages and speeds but none have been stable. I am aiming for 4Ghz (3.5Ghz stock). I got fed up with all the failure so I set the multi up to 4Ghz with stock HT and NB clocks and volts and put the CPU volt up to 1.5V (1.520V in CPUID) I have run it for 2 hours and has been stable, which is an hour longer that the previous failures.
I will run again overnight to make sure its good but is 1.520V too high? Temps maxed at 57° and 59° using speedfan (core and core2).
I have over-clocked most the CPU's I have owned and the fails usually end with a BSOD or a freeze BUT with this one I get an error in prime95 where one core will fail and the rest carry on (usually 3 or 4). the error has always been the same FATAL ERROR: Rounding was 0.5, expected less than 0.4.
Any advice would be much appreciated, also a side question, I left quiet and cool on but it doesn't seem to clock down when idle. is that normal?
specs:
CPU : Phenom II x4 970
Heatsink : Noctua C-14
Motherboard : GA-870A-USB3
RAM : 8GB (2x4) Gskill RipJaws
PSU : Ocz moodExtreme 700W
Windows 7 64bit
