FSB Strap to North Bridge : 400
Set this to auto.

DRAM Frequency: Auto = Otherwise unstable
Then pick a speed you know your RAM can handle. Shoot low for now. You can up it later.

Ai Clock Twister : Strong Relax = 0
Try setting Relax to 1 if you're having stability issues.

North Bridge Voltage : 1.49
Set to around 1.52
FSB Termination Voltage : 1.4
Set to 1.5

Try that and see what that does for ya.
