i7 930 @ 3.7ghz

i7 930 @ 4.0ghz

I'm getting a bit worried about the vcore :/

Prime-95 - 59-65c

So lower your core voltage a bit? 1.36 is high for such an overclock.

Your temps under load, for this CPU, are fine.

I would hope you could do 4ghz with less than 1.3v, but 1.37 should be more than enough. Certainly general experience would agree.

Try this thread.

***The Official Core i7 Overclocking Thread***

Or this one

BLOOMFIELDS CLOCK THE SAME

What is your vcore for 4ghz

Also the max vcore/vid for a bloomfields was 1.35v iirc, ideally it shouldnt need 1.37. How are the temps ..?

cpu voltage is fine for that chip,aslong as core temps stay under 80c,its all down to each cpu some need huge amounts,some dont,i would try and lower asmuch as you can though whilst remaining stable

Attempted 4.2ghz at 1.33 blue screen.

Got to 4.2ghz at 1.376

I'm getting temp wise

Idle (32-35c)

Load 1.4 vcore (60-68c)

Settled at this for the life span of my cpu 1.4v its to high :/

my i7 930 just doesn't like 4ghz

Were you adjusting any other voltages? Ie qpi and ddr ram voltage, theese two and vcore are the main three to adjust when overclocking the 900 series. Bsods ive found, usually relate to issues with qpi or ram under prime95.

wazza300 · 10 Jan 2012 at 22:21

Your temps are good at 68c with 1.4v @4ghz,they Arnt as fragile as sb regarding voltages

setter · 10 Jan 2012 at 22:24

Yep, incredibly good, better than what im achieving at 1.300vcore at 4ghz. But i strongly suspect that that vcore could be lowered a bit.

TommyGrule · 10 Jan 2012 at 22:43

If I try anything under 1.37v at 4ghz blue screen.

No I haven't tried any of them.

Ram voltage, check the info on your particular kit, most triple channel ddr3 needs 1.65v, (1.66v is fine as the increases only go up in two's). Some newer kits require 1.5v, but check your own specs. Qpi, your fine at upto 1.35v on this, id suggest setting it to 1.32v. Vcore wise, at 21x193 i need 1.2750 vcore, at 20x200 i need a jump to 1.300.
