Currently I'm Prime95 and LinX stable with 1.33V. I thought it was okay at 1.28V but got rounding errors on one of the cores during the Blend test. I'm slowing working my way down again to see how low I can go.

Corsair Vengeance LP 1600Mhz 4GBx2 9-9-9-24 (1.35V)

Auto OC may in fact put the BLCK setting from 100 to 102

I wouldn't want that but your mileage may vary.

Read the Asus tech reprsentatives settings and recommendations for these boards.
Its online. At Hard OC

Heck I even have my cpu capability at 100% only and I get my sig. 4.7

So i tried the Asus auto-OC thingy on the bios, and my computer now has to restart itself several times on a cold boot.

I'm thinking it's trying to figure out what voltage to supply to the CPU.

I'm getting really tired of it, so I was wondering what's the maximum voltage for the 2500k (just so I know so that I don't ramp it up to the max lol).

Thanks.

I read the max safe voltage (according to Intel's technical docs) is 1.51V as long as your temps are under control. What clock speed are you trying to achieve? I would start off at 4.5Ghz with 1.32V then lower the voltage until Prime Blend is unstable and bump it back up a bit.

Awesome thanks. I was having trouble finding the multiplier but I figured it out. Thanks!

edit:

Actually, is it normal for CPU-Z to show that my core speed and multiplier is changing from 1600mhz (multiplier @ 16) to 3800mhz (multiplier @ 38) when i open up a program or do something? Is it purposefully underclocking??

edit#2:

Anyways bumped up the multiplier to 42, so I should be running 4.2ghz at 1.25v...now to test.

restarting on a cold boot means the overclock has failed.
max voltage is 1.4-1.45
