P5Q SE Plus CPU Voltages

post #1 of 5
Thread Starter 
Hey Folks I have been attempting to OC my E8400 C0 Cpu everything has been going great I have managed to get it up to 3.51ghz stable, I will be pushing it more, Only thing is in my Bios I noticed that when my Vcore voltages are set to 1.30 in the bios it is showing up as 1.26v in CPU-Z. I know the safe operating Voltages for those processors are 1.45v.

So my question is which of those numbers can i rely on being accurate the BIOS or my CPU-z reading? Also when I look at the Hardware monitor within the bios the reading for the vCore shows the same reading as CPU-Z

neither can be ruled accurate however the CPU-Z is probably closes as there will be a voltage drop when the CPU is in use

Go by CPU-Z as that's the actual Vcore..

That difference between Vcore set in BIOS and in Windows is known as Vdrop and every motherboard has it..

Now Vcore will drop even further under program load and that's being known as Vdroop..

Keep the Vcore under 1.40V (LOAD) for safe 24/7 usage..

CHEERS..

Excellent thanks for the info guys, Will continue the OC process tonight would love to see my CPU @ 4.0ghz Although this may not likely happen as I am stuck with the C0 version of the e8400 xD

That P5Q SE Plus is almost identical to P5Q SE2 (Which I had), except for the Plus has a Digital optical out. These motherboards av a HUGE Vdroop under load! If I remember correctly, when I chose 1.35v Vcore in bios it dropped to under 1.20 Volts under load!

So keep that in mind.

Edit: It is possible the Vdroop was even bigger! I have never seen a motherboard with a bigger Vdroop under load. And this motherboard does not have Load Line calibration either
