I have OC my P4-650 (3400 default) to 4000. I have increased the CPU voltage to 1.4. Air cooling (CoolerMaster heat pipe).

Is it dangerous for my CPU that voltage :?:
Regards. Thanks in advance.

Intel specs these chips at 1.25 to 1.4 volts so you are running on the upper end of their specs... so yes, you should be fine.

Whats your idle/load temp?

38 C idle / 58C load Room temperature 20 C.

It is no stable at 4.0 (Prime 95), so back to 3.8 (rock solid).

Hello!

I just bought the same P4 650 and I'll get it next week. I had a Northwood 3.0
which was unstable at 3.4 ghz on stock voltage. I could not even change my voltage on my crappy mobo.

But for what I can remember, I had to use a memory divider and that made me lose a lot of performance. How did you manage your Ram with this 3.4 -> 3.8 OC ??

I will have 2x1024 DDR2 and im not interested in clocking them faster and I also don't want to lose any memory bandwidth to get an extra 400 mhz (11.7% +) on the CPU.
So that's why I'm curious.

I have an ASUS- P5AD2-E Premiun and it is very easy.

I have set the FSB at 224 and the CPU core at a very low figure: 1.30V because it runs stable and generate less heat.

The other settings at auto.

Thats all.
