eist & vcore voltage

[mofnet]

hi all,

i have a qx6700 running stable at 3.2 with nice temps/noise ratio... (i place quite a bit of weight on a quiet system, the last thing i want is not to be able to here myself think!)

i have left the eist enabled in the bios which allows the system to drop to a lower frequency when idle (good for power conservation).

I have tried to overclock above 3.2 which the processor does, but it isn't stable. I have noticed that no matter what i set the vcore to manually in the bios, it makes no difference. Is this because the eist technology has control of the vcore and no matter what i manually enter in the bios, the eist will always select the default cpu voltage, then drop it lower as it reduces the frequency at idle.?

any insight into the eist and cpu vcore relationship would be appreciated, is my interpretation of whats going on accurate?

i would like if possible to leave eist enabled as the ability for the machine to consume less power when idle is nice.

cheers
ian

Stable overclocking and automated power saving are basically mutually exclusive. Disabling EIST abnd C1E will give better stability across everything. What you are currently doing risks crashing your PC and losing data at the very least.

my setup is currently very stable at the moment running at 3.2ghz which i'm very happy with.. this is with all the power saving stuff turned on, so when i'm rendering (100% cpu usage), the eist ramps the cpu up to full speed which is 3.2ghz @ 1.325vcore. and when i'm not rendering, it runs at 1.6ghz @ 1.025vcore. so i'm well happy with that..

i were just wondering if turning the eist off would allow me to get faster speeds by increasing the vcore, and whether the eist was preventing my vcore settings from actually being used... just out of curiosity.
