I want my i7 950 at 4.6Ghz!

post #1 of 18
Thread Starter 
Hello,

I want my i7 950 at 4.6Ghz..

I have it stable at 4.5Ghz with VCore 1.47 volt.
And my QPI voltage at 1.4 volt.
PLL voltage at 1.81 volt.

I raised the VCore to 1.5 volt but it wasn't stable.
I can handle the temps.. Not above 75 degrees...

Please help me with this.

The IOH voltage = 1.2
IOH PCIE = 1.6
ICH = 1.2
ICH PCIE= 1.6

DRAMM BUS = 1.60

What do i need to change to achieve 4.6Ghz???

Asking 4.6 might not be possible unless you move past plain water-cooling...or it might not be possible at all. If you can get there, more power to you. But not all chips can even make it as high as yours, so 4.5 is already a huge achievement! Granted the voltage needed is a little high tongue.gif

Even if your temps are fine, high voltage will fry your CPU and cause damage over time.

You are already at a voltage that I personally would not use, you put any more voltage into that thing and I'd be surprised if it lasted over a year.


IMO - You are at the max that processor will do for 24/7, maybe a bit beyond it.

Intel data sheet lists absolute maximum for the cpu core is 1.55v, and 1.35v for the vtt....

Remember there is a Vcc overshoot (voltage spike) on idle - load transitions of .05v that should be accounted for, so 1.50v would be the max "safe" as per intel...

If you can keep it cool, and dont mind a little degradation I say go for it... Chances are you will upgrade long before you see the side affects from overvolting .03 or .05v


I wish I could do it, but I am having a tough time keeping mine cool enough at 4.0
