post #6481 of 10701
so munaim if i go buy another retail cpu brand new in box never used before and set the vcore to 1.5v will that cause it to require more voltage for X multiplier??? or is it only because of the ''burn in/settle'' that i am experiancing this frustrating nomnomonomoing of the vcores and while you say its cause of the settle ini thing for the last 2 weeks i ran the tests multiple times at the same voltages and it was stable (have screenshots to prove) but EVER SINCE I RAN 4.9GHZ @ 1.43V IN BIOS now im not stable at what was previously stable so i believe it has to do with IF YOU GIVIE THE CHIP MORE voltage (when i first got it i baby it up from 1.3 in 0.05v increments and stopped at 1.365v stable now require at least 1.375/1.38 and not stable!!!!) it is bad only maybe im crazy tho...

Yup, thats the plan munaim, to switch to offset once I know what my stable voltage is..so I will run this as is now and see if I can get 12 hours out of her and then try offset

now, ive read that you should subtract the voltage at load in realtemp from what is in cpu-z, and that is your offset..

but are you supposed to subtract what you set in the BIOS for voltage (in my case 1.32) or what it drops to under load in cpuz (in my case 1.304-1.312)?

Im assuming under load?

Okay, so I took:
CPU-Z core voltage (under load, it varied but the highest I saw was 1.432v)
RealTemp VID = 1.3611

This left me with 0.0709 (1.432 - 1.3611). I set 0.07 offset in BIOS, turned C3 and C6 off and changed LLC to High.

Opened p95, blend test and CPU-Z reported WAY lower voltages than 1.432v.

Changed offset to 0.0900 in BIOS (1.45 (vcore as set in BIOS) - 1.3611) = 0.0899.

Now CPU-Z reports (under load) around 1.392-1.400.

Did I do this right?

I notice the same thing with my p8z68 Deluxe. The calculated vcore offset was less than the setting I actually needed to obtain my desired vcore under load.

You beat Lord Xeb and taken the 5ghz golden entry smile.gif
Have you tested the max multiplier? With those kind of voltages I bet you could go much higher if you're on water. As for max multi might be a 57 or even a 58.


Thank you,

Actually my current goal is just trying to see what a 212+ can push my CPU too under 90c during Prime95 test.

I actually tried Vcore at around 1.304 range @ 5Ghz and it will run Prime95 fine, but it will just go to Blue Screen after I stop Prime95.

I haven't try test the max multiplier because I don't think my current 212+ can take it and keep it under or between 85c to 90c.

I will try to push it to 5.1Ghz and 5.2Ghz stable for 12 plus hours and trying to stay around 1.4v

Hi Guys,
New to oc.net forums as I was interested in telling my story smile.gif

I started off with an Intel 3930k and Gigabyte GA-X79-UD5.
This performed almost EXACTLY like the vcore curve someone else posted :
15g89ie.jpg
I ran 4.3GHz at 1.27v and couldn't do 4.5 unless I picked 1.41v as shown in the curve.
Unfortunately during this time the GB burning boards debacle started and I started hearing a VRM buzz coming from my board (got recordings haha).
This lead me to send back the GB board and order an Asus Rampage 4 Extreme.
Now strangely the R4E board clocked my chip to 4.5GHz at 1.32v 3hours prime stable as well as several LinX and IBT runs which passed with flying colors(just did moderate testing).
So I was all happy and stopped doing heavy lifting for a while and started more normal usage like watching movies etc.
Now after 2 days I suddenly had a 0x101 crash, so I was all huh ? retested prime and it locked up within a second.
I then had to increase my vcore all the way up to 1.41v to get it prime stable again...

I could call it cpu degredation but as it already ran at that speed before... can I really ?
Now running 4.3GHz at 1.27v again.

Didn't check my voltages using the OC key in the beginning so I am unable to comment if any of the "auto" voltages increased or decreased.
Obviously pretty annoyed because I really wanted that 4.5GHz but I guess I'm stuck with it as running 1.41v is unacceptable for me.

Success!! submitted for your approval, hope I didnt forget anything!! May I join pretty pretty please??

First time intel OC, seems like I got a great chip...I can definitley push it further, but I am happy with 4700 wink.gif

Not sure if it will help anyone, because all chips are different, but my BIOS settings for my 4700 overclock above are as follows:

47 multiplier
1.32 vcore FIXED (for now, until i change to offset)
CPU PLL 1.709
LLC level 2
Thermal throttling enabled
VTT auto = 1.059v
VCCSA auto = 0.925v
PCH auto = 1.059v
Internal PLL overvolt DISABLED
Turbo Boost Power Limit Manual
Short duration 250
Long duration 250
Long duration maintained 1
Additional Turbo voltage auto
Core current limit 250
Spread Spectrum disabled (was making my bclk 99.7)
C1E enabled
C3/C6 enabled
Speedstep Enabled


under load, i am getting vdroop between 1.304 - 1.312v, so that is why I set it to LLC 2
post #6490 of 10701
Ok, so I need some help understanding/setting offset voltage mode now that I am stable and I know my voltages.

In the BIOS I have 1.32v fixed, with LLC 2
Under load, I see the vcore dropping between 1.304 and 1.312v, so I assume my goal with offset is to get it as close as possible to 1.312v?

In realtemp, my VID under load is 1.3711 so I am supposed to take the difference of that and my load vcore in cpuz, so 1.3711 - 1.312 = 0.0591

So, my offset is approx - 0.06?

The part that confuses me is what am I supposed to set my vcore to in the BIOS? Since I want to be as close as I can to 1.312, so 1.312 + 0.06 offset = 1.372? And then set the LLC to whatever gets me closest?

Sorry, I am confused about offset frown.gif
