i've heard there are probs with this motherboard hence the reason why elite no brought out the new version 7. all i can say is i have experienced problems : hard crashes, machine rebooting, failing to copy large files.... i am running the xp 1700+ this is meant as information, aparently it works ok at slower clock speeds which i have proved to myself by changing the bios settings. if you are experiencing problems and are running this board check this out first as it has taken me three weeks and high blood pressure to find this out.
