Max vcore for a pentium 4 2.80ghz

post #1 of 8
Thread Starter 
Well this is my first overclocking session and I managed to get
my cpu from 2804mhz to 3234mhz with the vcore at 1.728V and
the temp at 41~42.5c (with my windows(not the OS) open XD, I'll buy proper cooling soon)

My question is; How high can I push my vcore without frying my cpu?
(btw I already read the sticky but it would be different for every cpu right?)

Rule of thumb for voltage should be no higher then 1.7, if your going higher then this then it sounds like something else is causing issues, because that CPU should be able to get to 3.2 without a ton of voltage. Im guessing your running a northwood CPU which usualy has a stock voltage of 1.5-1.6. Have you tried to test your stability? Idle temps are usless as the CPU is doing nothing but idleing, stress it with Prime95 or OCCT or something that will stress the CPU fully, if your temps get to 55c then you need to back off the voltage and get some better cooling.

ya your vcore is already over the "safe" limit... and your temps shouldnt break 55c as adeo. said.... post your load temps with prime95 running for about 5min. and well will help you from there....

47C is what it gave me for running it 10 minutes-ish

PS
I brought my cpu down to 3.15ghz and power to 1.696V ~ 1.712V

For Northy, it's 1.700, for Pressy it's 1.525.

It might differ depending on what cooling you have.

ya with a northy i would try and stay under 1.7. when you OCed, did you just crank the vcore right away or did you up it in small increments as needed?

Well I increased the CPU external frequency with 5mhz per boot and when it started giving error messages I put the vcore up with 0.1V and then repeated the whole thing till I couldn't get it higher put the Vcore up again by 0.1V and then I couldn't get it higher then 231mhz with the CPU external frequency & the vcore on 1.73V

I have now put it back to CPU external frequency-225mhz and vcore-1.6750~1.71V
