OCing my 3.0 prescott

post #1 of 3
Thread Starter 
hello. in my bios i can change my fsb, cpu voltage and system core voltage and also memory voltage.

i have overclocked successfully upto 3.2ghz by only changing my fsb from 200 to 210. now i want to overclock even more.

can u tell me how to do it and what other things i must change such as voltages.

also i think that my multiplier is fixed @ 15x.

TIA.
My System

Your multiplier is 15 so you must have set FSB 220 to get a 3.2 out of that Prescott.

Check this excellent guide for all the details: http://www.overclock.net/intel-cpus/...ing-guide.html

Standard procedures to follow before overclocking:
  • Make sure you know how to operate your CMOS jumper correctly
  • Make sure your PCI-E/AGP/PCI locks are locked at 100.0MHz/66.6MHz/33.3MHz (you will have either PCI-E or AGP, PCI-E is most likely)

As for overclocking, when you increase the FSB you will also increase the memory speed, make sure that your RAM does not operate much higher than the frequency its due to run at or else it may not work, this can be fixed by using either a divider or by increasing the vdimm (RAM voltage).

As long as your PCI-E/AGP/PCI clocks are locked you should be able to overclock quite far.

Note: Try to keep the vcore below 1.525v for a Prescott or 1.7v for a Northwood. As for temperatures keep a Prescott below 65C and a Northwood below 55C.

This is no where near a good answer of mine, resort to NoAffinity's guide for a better one, I don't have much time to post this, I can post a long answer when I get home
