I have to differ with the opinion on FSB settings.
A7N8X Deluxe
AMD 2500 Barton 200x10.5 multiplier
2-sticks 512 LL Corsair 3200
Asus 9600 XT - but not for long it's a piece of crap
I run this puppy with the FSB set at 200, never change it
That puts the Ram, the MB and the CPU in sync. The difference in test scores between running the CPU at 2100 vs 2200 is only about 10% increase. Not worth the instability to me. But...
when I bump the FSB from 333 to 400 performance and scores jump about 30%. The system reads it as an AMD 3000 and it performs like one. I can run the CPU at 2200 but it crashes when I play Forgotten Battles.
It has run like this for six months now and I have never had any issues related to overclocking.
The reason I stopped by here is problems w/ the 9600xt and was looking for compatiblity issues w/ the A7N8X.
Recommendation
Check Power Supply
Be sure you have a good heatsink and fan
Check Bios settings - this can cause blue screens too
Put a heatsink fan combo on the FSB
I took off the HS that came on the board and put a on Vantec copper orb that is really meant for a vid card.
Good luck and happy gaming
