Possible reasons for not loading OS

[( |-| |2 ][ $]

I've just bought a second hand Athlon XP 3200 to replace my XP 2500.
Trouble is I can't get it to load Windows at stock speed, or even past 190*2FSB. My XP 2500 loads at 200*2 FSB no probs.

The XP 3200 is trying to set it's Vcore to 1.8V as well which I find strange.

So aside from a nackered chip are there any possible causes of this? One issue might be power as it's only 220W but the XP3200 is compatiable with my system.(AOPEN XC CUBE Ez18)

So would an XP 3200 need more power at stock than an overclocked 2500?

System: AOPEN XC CUBE EZ18, Nvidia something 6200, m-audio sound card
2*512mb PC 3200 RAM cruical i think

PS i'm using Windows Vista but i'm sure it's not that because it crashes when loading the setup DVD as well.

If at the same vcore and speed then it should use about the same juice. What do you mean by 'past 190*2FSB. My XP 2500 loads at 200*2 FSB ' ? Do you mean you're running your 2500 at 200x11 for XP3200 speeds? (2.2Ghz). Try a BIOS update since it may be having trouble with the chip as it sets it to 1.8v.

Got the latest bios. Yes, I do mean my XP2500 overclocks from 166 to 200FSB no problem. But the 3200 which is meant to run at 200 won't even touch 191.

Sounds like a worn chip if power's not the issue.

Hmm, I might give it another try tomorrow then, might even give it the 1.8Vcore it seems to want.

If not I think i'll just sell it on again, after it could just be my board.
