How far should I overclock WITHOUT changing my voltage???

post #1 of 6
Thread Starter 
My processor is an Intel Pentium D 925 3.0GHz. I want to know how far I can overclock this thing without upping the voltage. Any suggestions?

I want to get at least a 3.5 or 3.6 out of it. If I have to up to voltage, could someone tell me how to do that?

Stock cooler on CPU, Antec Nine Hundred case stays very cool.

Until it becomes unstable, when its unstable it could mean one of two things. Ram has surpassed stable speeds so divider is needed to get back down to stable speeds. Next step if ram is within limits is to increase core voltage, and nb a tad.

I think that you should be able to reach that mark. But then again I am not a intel expert. A rule I use often with over clocking is 15% - 20% is a safe range with stock cooling and voltage.

Put your system specs in your sig, it will help us out.

You may be able to reach that without voltage increase. Got my pentium d from 2.8 to 3.5 with no voltage change

You can try setting your processor to 3.5 by setting your fsb in bios to 233 if it post run orthos. If it doesnt give erros for a few hours then you dont need any extra voltage.

keep increasing the speed til windows won't boot up then go back to the last known worked speed and run prime 95 or orthos.

You want 3.6 on a pentium D on stock cooling?!?! You should really invest in some aftermarket cooling, even if you could get up there, which actually shouldnt be too difficult, the heat is just going to kill the proc eventually.

In the bios you should see something along the lines of system voltages, or anything with voltages and the vcore is the the cpu's voltage and youll adjust that.
