I have two X5660s and a Tyan s7012. I had some issues getting it to post but was able to get it to post with a single X5660 installed. When I install the second, the system fails to post. I have updated the bios to the most recent revision. A green light blinks near the second cpu socket. I've tried multiple ram configurations, I have tested both processors on the socket without the blinking green light. The system turns on immediately when a cpu is installed in the socket that is not working. There are no beeps, or codes from the display. I have checked the other socket for bent pins and confirmed that there are none.
