Hi

When you overclock the CPU by raising FSB do you need to raise the vcore at some point?


And do you need a better PSU when raising FSB or is it only when u raise vcore??

Only raise the vcore if your overclock isn't stable. What are your PC specs?

1 if it becomes unstable and you want to go further than you are

2 neither as long as the psu is neither faulty nor overloaded

I get a blue screen... but i can raise 200mhz stably. after that its either blue screen of hangup.

So the PSU cannot become overloaded by overclocking?

Well it depend what size of a psu you have.

Say that you have a psu that is 400w

And all the components in ur comp take up exactly 390w so when you overclock it will use more power so it will use more than your 400w psu will be able to handle.

what cpu mb video and psu
August 12, 2009 11:43:06 PM

Processor: AMD Athlon(tm) XP 3000+
Mainboard: ASUS A7V8X-LA (kelut)
GPU: Ati radeon 9600
Memory: 2 x 512 ddr PC 3700 (400mhz but they run 344 i think , mobo doesnt allow to change)
OS: windows XP

the mobo's bios doesnt allow to change anything regarding overclocking so i use cpucool to change the fsb. so far i havent found a way to change the vcore...

sorry I'm not very familiar with amd products and i can't seem to find the spec sheets for the mb or cpu

Hi, i would recommend you do not overclock that cpu any more, i used to have an amd long ago and the chip / everything got messed up as i was using clockgen.

thanks freezed1. i find some stability problems even with the 200 mhz overclock :/ 
but i wonder if the better PSU fixes this.

505090: i dont know the specs either... only that mobo has:
Northbridge VIA KM400 rev. 00
Southbridge VIA VT8237 rev. 00

Then I found from the net about this same processor's overclocking, that a divider should be set, it was suggested as solution for the instability.
Unfortunately i cannot change that one from bios either.

is there a way to programmatically change the divider?

no a divider would be set in bios
