I am having problem with the CPU:RAM running at 1:1 ratio.
At 400FSB, 3200Mhz CPU, 1:1 DDR2-800 5-6-6-15 I'm getting numerous error in Memtest86 Test #7
At 390FSB, 3120Mhz CPU, 4:5 DDR2-975 5-6-6-15 Memtest86 seems to be running fine.
At 400FSB, 3200Mhz CPU, 4:5 DDR2-1000 5-6-6-15 No Boot

CPU is at 1.25V and Ram is at 2.05V, with all other voltages set to auto.
I wonder what is wrong with my setting, as it crashes running lower ram speed.
And I wonder how can I tweak those NB/SB/FSB voltage setting?

Last night I booted into windows at 433FSB 1:1, 4 minutes stable in p95 and immediate crash for blend. I'm very confused right now.

Cheers
Arthur
