<A HREF="http://forumz.tomshardware.com/hardware/modules.php?name=Forums&file=viewtopic&p=563388#563388" target="_new">I feel your pain.</A> Most times it's the RAM timings that are set too aggressively. In my case the BIOS was actually corrupted and I had to send the chip out to <A HREF="http://www.freewebs.com/tmod/index.htm" target="_new">Tmod</A> to be reprogrammed. I'll let you know how that worked out when I get my BIOS chip back probably tomorrow.
