What's a good voltage for 4.0ghz-4.4ghz OC'?

post #1 of 13
Thread Starter 
Hey everyone, I'm just tried the auto overclock feature on my Asrock Extreme4 motherboard and it seems decent to me.(I'm a total newb to OC'ing) I chose the 4.0ghz turbo setting and on Prime95 it gave me an average of 3991ghz core speed and 1.312 average core voltage. Now from what I've heard, people say that would be a bit high for the core speed. So I just wanted to know what's a good voltage for clock speeds ~4.0ghz-4.4ghz?
EDIT:
What should I use for my stability tests? Prime 95? Intel Burn test? Linx? OCCT?

It totally depends, CPUs are binned differently and each chip can run at a different voltage even within the same batch.

If you're happy with your OC then start lowering voltage until it becomes unstable, then bump it back one notch and you've found your chips lowest voltage for your given OC.

I'd recommend LinX(Linpack) 20-50 pass for faster testing than 24hr Prime95 blend. Always watch your temps with Realtemp when you run stresstests.

Aye, thanks though I use HW monitor and Core Temp to monitor my CPU activities. I will try lowering my Vcore to 1.25now

Ok this is very strange. I have set my OC manually to 41x multiplier so far it's running stable at 1.27 volts. The strange part is that my Vcore is 1.27 when idle and 1.20 when under full load. Can anyone explain??

Load Line Calibration- The lower the number the less voltage drop during load. (I run mine on 1)

Thank you, so even though the vcore is reported to be higher it doesn't consume more power?

Oh and since we have the same motherboard, what settings did you tweak? All I did was change the multiplier and the vcore.

Thats Vdroop aka LLC. It runs a higher idle voltage and a lower load voltage, it ramps the voltage better for the chip. Its a feature recommended by Intel.

People turn it off to get lower voltage overclocks but its better to keep it on.

If you want lower idle voltage you can enable EIST/Cx States, but should keep Vdroop on.
