P8P6PRO + 2500k

post #1 of 3
Thread Starter 
Hi guys,

I am running the p8p6pro + 2500k combination and recently just started overclocking. I haven't really touched anything besides the turbo multipliers, so far they are at 41 and everything is rock solid stable in prime95 for 12+ hours.

My question is in regard to voltage; I've left it at auto offset and am thinking that the auto voltage is way, way too high. Under 100% load in prime95 at 4.1 ghz, its pulling 1.38v.

Should I set a manual voltage? I was thinking something around 1.3 would suffice. Or should I leave it at offset, and if so, what kind of offset settings to use? The asus BIOS is not the easiest to understand.

Thanks in advance.

ps - I plan on leaving the CPU at 4.1 or 4.2 ghz. Just looking for some kind of voltage estimate from the community, as I realize all chips are different.

Yes, it would be better to set a manual voltage since 1.38v is definitely too high for "just" 4.1ghz.

My 2600k can do 4ghz with 1.180v and 4.2ghz with 1.200v, if I set it manually.

I'm sure your 2500k can do it with low voltages as well
