That isnt true, with a bios flash it the p5nd2-sli will run a c2d, i just dont know about a quad core. The manufactures website says it will not, but that is incorrect. It can be made to work.
French, your reply is over 2 months old, but I'd like some further comment on this issue. I've flashed my P5nd2-sli's bio to the latest version (0701, I believe), and would like to know if that's all I need in order for it to run a core 2 duo. If not, what other steps would be necessary?
Thanks in advance,
