I7 Voltages

Hey, can you please check if my voltages are fine for my OC

for 4.0ghz stable i need:
Vcore bios 1.38v, cpuz 1.34v and 1.30v load
QPI/VTT: 1.335v
IOH: Auto
Ram:1.66v

thers a massive jump in vcore for the last 100mhz, over .03v

yea its a D0. i cant get it stable with lower vcore.

any advice?

although the temps only reach a max of 80

and is there a possibility i have a chip that just requires higher voltages even though its DO stepping???

for 4ghz, i was hitting 83 on Prime.

for 3.9ghz, i need 1.35v in bios, 1.28v load cpu-z, which hits temp of 80

kinda weird since people with a lot lower vcore hit similar temps

tinkered with the chip all week and had no luck, decided to sell the chip + board to family member.

got new 920, now clocks to 4ghz with only 1.2vcore load

and with temps of 73 max.

One tip which will probably get me in trouble: dont buy OEM as my chip had marks on the surface which at the time did not concern me. Have a suspicious feeling it had been tested by OCUK in their bundles and deemed a poor chip.
