Ok heres whats happened, i just recently upgraded my computer from an XP1800 to a XP2500 and upgraded memory from 2 sticks of Crucial 256 PC2100, to 2 sticks of K-Byte 512 PC2700. I have an A7N8X which supports up to 400mhz fsb. So now that I have my new 2500 and ddr333 ram, i should be able to run at 333fsb. Well everytime I do Windows XP crashes after a while, and games crash. Right now it running pretty stable at 266fsb and downclocked to an XP1900. So I called asus tech support and they told me to repair windows xp. They said that it should be running at 333fsb. They said that it could be either defective ram(which its not) or not enough power. Right now I have a Skyhawk 300W psu. Oya and bios is updated and the 2 sticks are running in dual channel mode(which isnt the problem either). Do I really need a new power supply and does anyone know any answers? Thanks

300W psu (+5V=30A +3.3=20A)
Athlon XP2500
1 gig of PC2700
Geforce3 Ti500
Audigy X-Gamer
DVD drive
CDRW drive
80gig harddrive
4 case fans

Well I use a 400W PSU and only run a Duron, would not use anything less, I also have XP Pro and it is running daily, no probs.

Take a look at post...Subject: K7N2 Delta-L install xp problems 7/19/03

You definitely need a bit more power. 400 wouldn't be too bad. And for the 333 fsb I think your going to need some very good memory.

i'v encountered a buggy Athlon once, it didnt want to boot at 133 FSB but it booted at a lower clock
