I began OCing my brand new 2500k on an ASRock z68 pro3-m, i am now at 4500 with vcore 1,32.
It has passed IBT (30 passes standard), but when i test it at High or above levels it comes down to 1600 every minute for 3-5 seconds . Max temp is 70ºC (thanks to pull-push on an Antec620 and good case cooling).
I am installing Metro 2033 and Civ5 to see if this is affecting gameplay, but does anyone have any ideas why it could be acting like this, that is, lowering the core from 45 to 16 every minute?
thanks for the help!
More about :stability testing dropping core velocity minute ibt
Dropping from 4500 to 1600 is totally normall , the frequency will drop when CPU is idle ...
but if ur having drops to 4200 ~ 3200 from 4500 when IBT ing then
try these settings :
Short Duration power Limit : 250
Long Duration Power Limit : 250
Spread Spectrum : Disabled
Core Current Limit : 250
Internal PLL Overvoltage : Disabled
CPU LoadLine Calibration : Level 2
CPU Core Voltage : 1.32
CPU C3 State : Disabled
CPU C1E : Enabled
Package C Support : Disabled
It would seem so. It appears to occur only with IBT for some reason...
I have been playing BF3 and ME3 and checking the temps on a second monitor - they rarely went to 60C, averaging on the lower 40C.
I guess now im up to OC my GTX560ti =D
