i got 2 920 cpus ones c0 oned d0.. Ok heres the point of this,
I got 3931a324 batch d0
and 3839a594 batch c0
i got ht on and trubo on o i got 4,200mhz.
ok this is the part i need help with, Im running 1.375 volts lowest i can go if any lower bsod. @ 4.2 with ht off i can do 1.337 volts. It seems like thare high.
Dose anyone got away to keeps volts lower. Like raising the qpi vtt or qpi pll or something in the range of that ? To many treads to read thought , On the 920 co i can get 3.2 @ 1.2 volts. Well. let the games began . I know my mobo is not the best for overclocking but still.

the uncore/vtt = the L3 memory cache and IMC, and the pll is the clock generator. So in short, no theres not really a another voltage that you can substitue for vcore. But 4.2ghz @ 1.375v is a pretty good oc... some D0s have trouble hitting 4.0ghz believe it or not.

If you're really determined to lower that vcore, you could try bumping the vtt voltage and set a 300ps clock skew.

well i could hit 4ghz on old c0. I got anew cooler coming in. with prime 95 i hit 82 degs . and thats too hot for me. I like to be jut to hit 70 degs, just keep reading ppl hit 4.2 ghz with like1.27 volt. Cooler i hope to hit lower temps is 1,900 RPM 110 cmf push pull and that mounted on to Prolimatech Megahalems Rev B. should keep 5-10 deg cooler i hope.

keeping the temps down will help. But those amazing 4ghz @ stock or 4.2 @ 1.27 are usually people that got lucky with a good overclocker... most people will hit a wall at 4 or 4.2ghz.

Do you got all cores on, turbo, or ht on(muilt treads) also whats you qpi settings? just thinging if i lower cpu volts and mess with the qpi vots i could get lower temps. also i know my mobo gots only 8 phase power. newer mobos got 12-24 phase.

Yes, i have all cores on, turbo enabled, but HT off in the oc in my sig. The cpu will use the same voltage and generate the same amount of heat, whether is 191 blck x 21 multi for 4ghz or 200 bclk x 20 multi for 4ghz. The higher the cpu multiplier, the less overall heat your system will generate because the mobo isn't being overclocked as much.

Your board is a fine overclocker, don't think it's holding you back. I've had over a dozen different 920's, and only one is capable of 4.2 at less than 1.3v. Your at 1.375, is that in bios or cpu-z reading in windows? You don't say what your memory is at. I would set it at x6 multi just to rule it out while you are finding the limit of the cpu.

that is in bios. memory is corsair 8-8-8-24 t2 @ 7-8-8-20 -t1 rams @ 1.64 volts cpu/pll 1.88 just cant do qpi voltage. can do both pll and vtt the resign i say mobo is not good. is because the mobo just has 8 voltage regulators, its notas clean power as most mobos.

hell I wish my d0 get 4.2ghz at 1.375 volts, this brick needs around 1.44, that's not half bad at all, more vvt maybe?
