I'm now at 4011MHz with my P4 630 and it won't go any further just pumping the fsb, so should i rise the voltage of the cpu next or what? And how much is should rise the cpu or vdimm voltage if that helps? :confused:

edit: The pcie bus is on auto mode, spread spectrum is disabled, pci clock is set to 33MHz, dram freguancy is on 2:3 and that means when the cpu is running at 267MHz fsb the memory is also at 267MHz so the memory isnt holding me back.

Hey i would appreciate any help from you guys :)

You got 4ghz with no voltage increase at all? Not too bad, try raising it to 1.425 or 1.45 if you have good cooling, past that it should overheat quite a bit. Set youre PCI-E frequency to 100, thats the default lock setting, then try raising the fsb more.

If you're using DDR2 try upping the vDIMM to 1.9-2.0 and if you have DDR1 try 2.9-3v.

Thanks a lot mate, that should help me for now :) And yeah i didn't increase the voltage just the fsb and i'm at 4GHz. I have Antarctica waterblock on the cpu so it should be cooled pretty nicely.

Increase the voltage to 1.5v, you should reach 4.2Ghz easily

I tried upping the voltages and i'm at 4.2GHz now so i quess it helped :D I have to oc some more, cause this ain't enough :D The temps are bit high now cause at idle the water tempereature is 36 degrees celsius and cpu temp is 46 , but i think the room tempereature affects that very much cause it's very hot in here :slobber:

My 630 runs 4,2GHz (15x280) at 1,375v on a Asus P5WD2 Premium. Try not to pump to much voltage into these chips if they're for everyday use. My friends P4 540 started the "Sudden Death Syndroms" after a couple of months at 1,54v.
The chips are excellent overclockers so I would'nt go above 1,45v... that's unneccersary heat and decrease of lifetime just to get 100-200MHz more. The clock speeds archieved at stock voltage are good for everyday use (4GHz+)

Hmm, if it is so then is should lower the voltages :( More benching when the air tempereature gets lower :D
