I5 3570k E1 and Gigabyte Z77X-UD3H

That's beyond me. It's my understanding that no material is 100% conductive, meaning there should be some kind of VDrop. But right here in front of us is showing your board as showing no VDrop. I don't know. This definently isn't my line of specailty though.

like i said load-line calibration is at Ultra high...could mean the board is adding on it´s own 0.15V to Vcore on load.

possible

On normal it stays at 1.2V and drops a few times to 1.85V And of course.....crashes....

so Ultra high adds 15mv

I am testing for 4.4ghz. It is stable in prime with 1.404v as shown in CPUZ. Should I only pay attention to the CPUZ core volt number rather than the bios number?

Edit: and its crazy hot. 86*C max!

Edit2: IBT runs it at 99*C, time to abort!!! I'll try gradually lowering the voltage and see if it remains stable, I kind of skipped a lot of voltages because I got tired of getting BSOD and having to reset my CMOS.

Edit3: The BIOS was set for 1.350v but the CPUZ was reporting 1.404v, is that typical? I just tried lowering it to 1.345 volt, to see if it can lower the temps.

Edit4: with BIOS set to 1.345, CPUZ shows 1.416v. Whats up with that?

I hate my cpu already reaching over the 60s i my self try to keep below 72C°

Does your mainbaord has Load-line calibration? And if what did you set it to.

My board on auto settings and auto oc applys 1.34V right of the bat for 4.2ghz so watch it don´t fry your cpu with testing!

I noticed that my voltage stays at 1.416 despite lowering it in the bios. Is this the offset voltage I have been reading about? Is there a way to disable?

as you can see in my screenshot of my bios i can set it to Offset or manual.
Offset just deceases or increases the standard voltages of your cpu.
for example your cpu runs on auto with 1.2V and you set offset to 0.2V you will get 1,4V

I don't see any way to turn off the offset. I changed my vcore from auto to 1.35 and it greyed out the DVID +.0v. Is the DVID the offset?

Then you set it to manual mode every Brand is calling it different in their bios.
Check your Load-line calibartion <---could also be named different

quote from a review of your mainboard :
With my Core i7-3770K, I was able to attain 4.7GHz at reasonable voltages on the GA-Z77X-UD3H; just like what I have done with other motherboards I have tested with it. To achieve this, I changed the PWM Phase Control to 'High Perf', Vcore Voltage Response to 'Fast', and Vcore Loadline Calibration to 'Extreme'. Next up, the CPU voltage was modified to 1.270V in the BIOS, with a minor adjustment of the Vtt, PLL, and IMC voltages to 1.060V, 1.085V, and 0.930V, respectively. Overall, I am quite pleased with this overclocking result, as the Gigabyte GA-Z77X-UD3H delivered on everything as expected.

Got it. You set it to Normal. It still says +.00v but once on normal it no longer adds voltage to the custom cpu core volt parameter.

Just tried this. Voltage went to 1.356 load from 1.345 so these settings do add some kind of voltage addition. I guess I should try these settings but lower my core volt in the bios to get it back down to ~1.350. I am running IBT. Its very very hot. 91* C max but its stable at 4.4ghz. Now lets see if I can get the temps down by lowering voltage again.

Try first how far you get with 1.25-1.3V much saver range for Vcore for the cpu

OK will do. Maybe now that I have the voltage settings correct it will overclock farther with the default voltages.

My super pi is 8.315 @ 4.4ghz, pretty good!

once you found a stable setting post a core temp cpu-z screenshot under load for temps and Vcore

Will do. Thanks a lot ruff0r (and everyone else!), its not such a crappy chip after all, just confusing bios

[amp281]

How does this look?

Prime 95 temps are 62-70* fluctuating.
Intel Burn test temps are 75-82*C fluctuating.

I would be happy with that for now. Maybe try tuning the voltage down some more, but those settings and temps are totally acceptable and safe as long as your not going to run at full load for extended periods of time.

Agree with big wolfy there...also *throws old E6850 at him* you can have him he has done good work

[amp281]

Thanks Barbaricsoul, I tried lower core volt but this was the minimum to get it stable unless i am missing some other bios setting again. Its been prime stable 2 hours now, 60 to 70 c never higher than 70.

I've been reading about delidding and it sure sounds tempting... I just don't want to spend another $180. Maybe I'll try it in a few months when I have some more spending money (physical therapy is eating up my money quick).

are you talking about Removing the IHS? if so ...yes and no.
If you got bad temps spreading over your cores. for example core0#60C° ,core3# 75C°! then yes that would solve it and bring both cores down to nearly the same temps...
FYI: i killed my first chip i tried that on but that was soldered and not like the 3570k with thermal paste which is pretty easy to do and could get you better temps

Yes, removing the stock heat spreader and installing a thin bead of thermal paste. Some people are getting 15*C to even 20*C cooler on air! Right now though its still running great. Prime 95, almost 4 hours in, about 68*C on average.

Note that all of those results with those big gains are usually replacing TIM with Coollabratory Pro, and from what I've seen, most are using watercooling to get 20C difference. 10-15C is about average.

me, I got about 10c with my 3570k on air, using MX4.
