Overclocking a D975XBX and Pentoum D 930

[jbizzler]

I've been trying to use ITK to bring up my CPU clock speed. Pre-ITK, I got to 3.75GHz(+25%). Then with ITK, I managed to bring my FSB to the 1067 setting, but had to underclock to 3.79GHz(-5%). The only difference now is 0.04GHz and now much lower memory speed (used to be 1000MHz, now 760MHz). I was wondering what other settings I could change to aid in my overclock, concidering I've seen Pentium D 920s at 4GHz with stock cooling, while I have a 930 with a CNP9500.

Play with volts and timings til' you get it stable or get better cooling.

Isn't this one of the best air-cooling systems out there?
What voltages would mean anything other than the FSB volatge?

You know there is better cooling than air though right? Look in the water cooling or phase change sections of these forums for some examples. The dual core P4's can get pretty hot when you clock/overvolt them enough, usually you end up heat limited.

Vcore and VDIMM are some other voltages you can try tweaking to see if you can get it stable.

Okay, thanks. I managed to bring my 3GHz Pnetium D 930 to 4.25GHz!!! I think I can go higher, but I don't want to risk it.
