M7NCG 400 Not Stable @ 400 FSB

[fletch259]

Hello all,

I have a problem with my M7NCG 400 system. I have it paired with an Athlon XP 3200+ and 2GB of G.Skill ram in dual channel configuration (1GBx2). Problem is everything runs great with the ram set to SPD in the BIOS, which defaults it to run at 333 FSB while the CPU is at 400 FSB. If I set the RAM to AUTO, it runs at 400FSB, but will give graphic artifacts and lock up the machine in XP. This happens whether I use my old Geforce 4 Ti4600 or brand new Sapphire X1600 PRO card. What could be causing this to happen? I have it powered by a 330 watt power supply, this should be adequate. Do I need to set specific memory timings in the BIOS (if so how can I find out what the correct timings are?), or is the motherboard bad and need to be replaced? Thanks in advance for any insight into this problem.
