Hi i overclocked my cpu like half a year ago its still running stable at 4.0 GHz<br />
its an Intel Pentium 4 515 2.93 GHz 1MB L2 533 MHz FSB<br />
Family: F Model: 3 Stepping 4 <br />
Ext. Family: 0 Ext. Model: 0 Revision: 0<br />
seems that one guy made 5281 MHz with the same processor with the same stepping exactly the same processor as mine<br />
when i raise the fsb over 184 MHz x 22 <br />
i cannot boot anymore my pc wil automaticly reset to default speeds<br />
its an Gigabyte GA-8S648FX LGA775<br />
now i need to know what my bottleneck is<br />
is it my PSU it is an 300 Watt generic psu<br />
is it my mobo ? <br />
its ok if nobody knows but maybe from the symtones u see what it is <br />
if i overclock it to 4.00 GHz and clock some past that i made 4200 MHz CPU-Z verrified its an +10% incraise voltage and my mem is not 1:1 so the mem is not the problem

Gigabyte boards arnt the best overclockers, but the biggest problem I see is the PSU. At <b>minimum</b> you should have a 400W PSU powering that system. 500W to be safe.

have you tried raising the vCore manually? you might not have enough vCore to sustain that overclock.

my mobo only gives the options to raise the vcore<br />
- 5 %<br />
- 7.5 %<br />
- 10 %
