p5n32-sli se and XMS2 2GB DDR2 1066 (PC2 8500)

I have been suffering with this combination for a few weeks. My system would randomly lock-up under load at default settings in bios. Unfortunately the BIOS reads these memory modules and assigns the speed to be 800 mhz at 1.85 volts. After re-reading the manual there is no mention of any 800 mhz compatible memory, only 533 and 667 listed. After lowering my memory speed to 667 I finally have a very stable system. I can now run 2 instances of Prime95 with 3dmark2001 looping endlessly for 24+ hours while overclocked to 3466 mhz( 266 FBS * 13 multiplier).

 

My questions are:

1) what voltage do you recommend for the XMS2 to get as tight timings as possible at 667?

2) what are the tightest timings have you found to be possible with this combination of mobo and memory?

3) any chance that a bios update will improve memory speeds?

1. The Corsair DDR2 memory is fine and within warranty up to 2.1v.

2. I have heard that the 8500 "might" run the same timings as the 6400C3 at DDR667 speeds. It's made with the same ICs so you will just have to test it. It's similiar to the way the PC3200XL/PC4400C2.5 DIMMs, and the PC3500LL 2gb/PC4400Pro 2gb kits are actually the same ICs underneath.

3. It usually is best to run the latest bios but again, no guarantees.
