P67-UD4 Auto Voltage Overclock, Am I Safe??!!?

post #1 of 8
Thread Starter 
I have a 2600k with a giga P67-UD4.

I used the Turbo feature, leaving the base multiplier at x34, but moved the turbo up to x40 while using 1, 2, 3, or 4 cores. Everything else is left as is(auto).

CPUID Hardware monitor and CPUZ both claim my VCore is at 1.068 while under load. With no load they say my vcore is 1.056. Are these numbers right? And if they are, and I can pass 10 runs of IBT as well as 8 hours of prime I should be fine with this correct?

My max temps are 55 under load and 21-29 (big range huh) under idle.

Thanks

The ud4 b3 displays the VTT voltage in cpu-z, to see the vcore use hwinfo32.

So you think that the voltage is higher than what it is saying? Let me download HWinfo32 and see what that says. Ill get back. Thanks

Ok... So HWiNFO32 is claiming my VID (Vcore?) Is 1.3311 V while running prime. This seems pretty high for x40 multiplier huh ?

I guess I am just a little confused. I have read a bunch of guides but was only getting blue screens.

Am I suppose to change my turbo, or the base multiplier. Basically can I change only the multipier, and votage, and leave everything else on auto. I am very rookie (my first overclock) and dont want to screw anything up.

game plan: (not sure if i want to do this on turbo, or regular multiplier)

Set multipler to ~40-42x
set voltage to 1.33
test stability and go down from there

Am I on the right track? I would take a lower overclock If I can leave the power saving features on.

I'm still pretty new with the sandy bridge rig, I disabled the power saving features (not a daily driver rig) & just set the core voltage & upped the multiplier, leaving all else on auto.

Looks like you are on the right track, if you are completely stable at x multi & x volts then you can either reduce volts & test at the same clocks or increase clocks & test at the same voltage.

Thnx for ur help 420. I would rep you if I knew how. (or roll one up if i saw you smile.gif )

I may just stick with a modest x38 in the turbo and let everything else be. Really dont want to screw things up.

Thanks again for your help, and showing me hwinfo32!

No problem, taking it slowly never hurts. You still have headroom to clock it higher as you get more comfortable with it, still in very safe voltage & temperature ranges.

VID is calibrated directly by Intel from the factory. And as long as you are using fully "supported" turbo multipliers (example: 35-38 on a 2600k), then the VID shown is 100%, fully, completely safe, as this is tested on all CPU's by Intel.

Once you go beyond the normal "built in" turbo functions and start going manually up to x40 and beyond, the VID still increases on how the CPU was calibrated, and of course, the vcore the CPU actually needs for stability may be much lower than the current VID. But this becomes a crap shoot as you overclock farther, as Intel does NOT test the cpu's to see at what voltage they will be stable at 4.5 or 5 ghz. Rather, the VID shown will be what the CPU needs to at least power on successfully, since you're in non-supported area here. For example, once you get close to 5 ghz, the voltage the cpu needs for stability may be much higher than the VID shown for that frequency. But the CPU should still POST to bios.

Read an article on how VRD 12 works, for more information about VID and frequency.
