something about ASUS P5KC:
Cons: This motherboard has a big problem running numerous makes of 8500 (1066 Mhz) RAM. Checkout their support forums (
ASUSTeK Computer Inc.-Forum-) to see all the people with 8500 ram having to run it at DDR2-6400 (800Mhz) speed for it to run stable!
Overall: Misleading advertising for Asus to claim it supports DDR2-8500 (1066) when it doesnt. Hopefully this will be fixed in future BIOS release, but its looking doubtful given ASUS's lack of reply to the numerous support tickets/complaints about the misleading RAM support.
