overclock I5 2500K to 4.3 (43 X 101MHZ)
mb: p67x-ud3-b3
ps: ss 620w
gpu: 6950 2gb dirt 3 (oc to 925/1475)

the problem is the vcore i put 1.275 & i see on core temp 1.0 rc3 1.3711/1.3661 in cpuid i see 1.056.

i'm in tesr prime 95 (256KB) i have stop it after 1H & 10M

i have found core temp to be unreliable for monitoring Vcore. if you have speed step enabled that is why cpuid is reporting lower Vcore.

you could do some tweaking the the BIOS to get it perfect but if your temps are fine and getting no errors in prime95, " if it ain't broke don't fix it"

no errors ^^
& max temp 75 avg is 64 so i'm ok ^^

I would use cpu-z as this is the most accurate frequency figure. Otherwise, it looks like you are set.

i5-2500K - P67 Overclocking

ASUS P8P67 WS Revolution B3 (nf200)
(PLEASE NOTE THESE ARE MY ACTUAL SETTINGS AND ONLY A BASE FOR OTHERS.)

* hit multiplier to 44
* disable turbo boost
* disable speed spectrum
(some motherboards will disable turbo when speed spectrum is disabled)
* LLC - regular or medium (x45 and below)
* Phase Control - optimized
* enable internal PPL overvoltage
* enable execute disable bit
* enable Intel Virtualization Tech
* disable CPUID Maximum
* disable overspeed protection
* CPU @ 120%
* CPU voltage - offset mode (-0.015)
* long and short duration times, set them both to 150...
* make sure power saving features are enabled:
C1E, C3/C6, CPU EIST
* set hardware monitor | fans no less than 62.5%
* XMP RAM
* save and exit
* boot into windows

default voltage levels with multi up to x43: 1.24-1.26V
multi x44 up to x47 voltage: 1.30 - 1.375v

LLC - load line calibration
x45 = medium / x49 = high

CPU temp: idle @ 30C (package) / load @ 61C
CPU cooling: CM TX3 with dual 92mm fans (push/pull)


tweaked my 2500K unit....
