Hi there, and thanks for the replies to my last post.

System:

1. XP3200+
2. 2x512mb PC3200 Corsair memory
3. 9700 Pro graphics card
4. ASUS A7N8X Deluxe motherboard (rev 1.04 - was only 333 FSB)
5. 360W PSU

Having just upgraded to the XP3200+, I updated the bios to support FSB400. After also updating the nforce drivers, this seemed to work fine.

Problem is system seems stable until I do something intensive (eg run 3dmark03 or start Ut2003) - then the system just freezes.

I'm running all the bios settings at optimal for stability.

Replies to my previous post:

1. Try running voltage at 2.7v - did not help.
2. Run memtest at different settings. Memtest ran ok for 10 cycles with system on proper settings. Only reports error (and system freezes) again when start up any intensive program.
3. Replace motherboard with new a7n8x - apparently the nforce chip was changed from earlier versions and actually doesn't support memory and cpu at 200fsb).

I've been able to run the system at 166fsb, and multiplier 12.5 so think it is maybe the ram (or mb at fault).

Any other suggestions?

PLEASE?!

You can try to increase you FSB by step... Test your system at 175, 180 and 190 FSB.

try some extra cooling on your northbridge chip. Put a fan on it or something to test.

Are you running Raid?
how many hdd do you have in your case running?
how many cd/dvd drives do you have?
how many fans? lightings in your case?
brand of your PSU?
occupied USB ports and for what purpose?

A fine day!

The north bridge and the voltage regulators bothe run too hot at higher fsb. Try taking the side off, and aiming a good house fan at that part of the board. If that does the trick, add a new hsf to the nb and glue some aluminium to the vregs.
