A8V cant run ddr400

[saadu]

I have a 1 gig of Twinmos (2x512mb) PC3200 DDR400 with 2.5-3-3-8 200Mhz according to SPD settings in CPUz. But for the system to remain stable without random stop errors at 0x000008e, i have to reduce the memory ratio and have it run at 333 as 2.5-3-3-7. Has someone elese experenced this or am i doomed to run my system at a lower speed than its capacity? I dont want to overclock but i dont want to run the system at a lower spec than what i bought it for.
Also, in the AI overclocking, i have left it to auto, but i have a feeling that it tries to overclock. Im not too sure about manual settings, could someone recommend me default settings for the cpu and memory
Thanks

You put the RAM into the correct pair of sockets? Else you'd have them both on one channel, and then, the reduction to 333 would be a perfectly normal requirement.

Yes i put the ram in correct slot (blue) as per motherboard manual. And while booting the bios informs me that dual channel is enabled. I got rather disappointing reply from asus. Some dude from china wrote me saying why i put non recomended ram in the motherboard. And also all my board are belong to them hence i must do as website. --typical confucious mentality there.

I hate their mobos.
