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.

Usually would'nt work but every now and then a chip boots but fails to work right. Anyway to test in another board? Am curious about this, i'd give you a few quid for it just to have a mess around, the last chip i got to test like this died within a week.

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.

But don't sell it on before testing in another board!

Wrong FSB setting on the Motherboard 166-200mhz
Not cleared your CMOS after installing the new CPU
Poor heat transfer
Borked hard disk
Borked windows install
PSU slightly out of it's depth

Could be any of them, try the FSB settings and the CMOS first and try the bios flash a few times just to make sure all the pins jump properly, a little tip from a guy that writes bios code for Asus give me.

Right.. gonna see if the pins on my board jump properly! I think you may have been talking to a tier 1 Asus support staff or something dude lol, advising someone to try a BIOS flash a few times is highly dangerous, unless he meant a BIOS clear

The BIOS flashing will make sure the pins or gates have jumped to the new position(you wont see anything jump) somtimes they stick in one position and cause odd problems, just like this. it's not dangerous just flash,reboot flash and make sure if your using a pre payment meter you have credit.
And i dont mean jumping the CMOS or somthing "dude"

I think he meant putting the jumper in the clear position a few times 'dude', once you've flashed once you've basically replaced the last BIOS and sometimes one might flash the bootblock too, though this is not common practice. If you actually know what you're saying you'd realise that theres no 'pins, gates (well not the gates you're on about) and jumps' in a CMOS chip, if you thought it out rationally you'd realise he meant to put the CMOS Clear JUMPER on the Clear setting, which is done via putting jumpers on the pins to whichever is the Clear position. He said to do this as even doing that sometimes dosen't clear the BIOS properly the first time around especially if you did'nt leave it long enough. Flashing a BIOS can cause irreversible effects, especially if its a soldered BIOS, while its easy its also easily messed up and sometimes even doing it right can result in a dead flash. Argue how much you want about it now
