i also have the same question, here is the screenshots

450

Besides, I wasnt able to find a place to set the vcore, and the turbo cannot be turned off. Currently trying 4gz and the vcore keeps changing, is it possible to get it fixed?. Prime95 full load will get it to 1.172v and temp around 80C. I think it would be possible to run at lower voltage but cant figure with this asrock pro 4. a screenshot of CPU bios setting as below. Any thoughts are welcome biggrin.gif

looks like you have to set the vcore through offsets, which is not optimal for OCing IB as the stock vcore will change, but i guess go with it, find your stock vcore and set voltage on top of that. That is the Pro4, it uses a STMicro analog PWM, i didn't think it would be that bad as you can't set manual, but it does look like you have to set Vcore through offset.

So don't touch those limits, if you start getting stuck, then increase those limits to the max you can set.

No I have the voltage in fixed mode at 1.32. I have the plane current limits set to auto since I have no clue what they do.

Also they do not have selectable limits. It is a static value you have to type in or leave it set to auto.

It is the ASRock Z77 Extreme4. Seems legit , I am at 4.7 but I believe I need to start increasing some other values. On my q9550 I had my hands in all types of different voltages, pll vtt tons of nonsense. I need to learn more about this mobo to get a better oc.

Temps are killing me though. I read somewhere it is because of the small die size.

Played with offset for a while, from -0.7 to + 0.45, unable to get to 4.5 without satisfactory temp. Currently running at 4.4gz at +0.2v (full load vcore on CPU-Z is 1.2v) max temp ~ mid 80s, looks ok but Prime 95 crashes after 10 min instead of giving error msgs or BSOD. is it possible to reduce PLL voltage below 1.8 and VTT/PCH voltage below 1.05 to help reducing temperature?

@aar0nsky, Temps are killing me also, what temperature u get with prime95 @ 1.32V and what cooler are you using?

PLL can be reduced. I'm running 1.5 right now. Note, it doesn't work for everyone.

I was however, able to go from 1.275v 46x to 1.325 47x by reducing the PLL from 1.8 to 1.5, and keep my temperatures the same (80c load in Prime95)

@aar0nsky, Temps are killing me also, what temperature u get with prime95 @ 1.32V and what cooler are you using?

I have 82*C+ temps in prime95 right now @ 1.32V. Im running a water cooled setup with a 2x140mm rad and an xspc raystorm cpu block and xspc rasa gpu block both in the same loop. Ambient temps right now are 27.0*C.

I can help you out, ive got the board pretty much figured out except the primary plane stuff. you have some values that need to be changed. refer to this guide as it is very similar but take it with a grain of salt since I am not sure the differences.

And about the voltage, set your CPU Voltage to fixed instead of auto or offset. then you can set a value for what exact voltage you want. Also turn Load Line Calibration(LLC) to level 1 to hold that voltage all the time(reduces vdroop) I say reduces since it is not sticking 100% for me.

@aar0nsky, Thx. tried at bios, seems like the cheaper version pro4 dun have an option to set fixed, CPU voltage is either auto or offset.. and LLC only has option of 100%, 50% or 0%. no clue what would level 1 would translate into that. too bad extreme4 was out of stock for the promotion, otherwise would have gotten that instead of pro4 ~.~

Isn't offset voltage better than fixed, since the voltage reduces when you're not doing anything intensive (ie. web browsing)?
