I used that board until recently. Fill out the foxconn support form and request bios file p08 for that board. This file isn't on their webpage. If the new bios file still won't read your cpu correctly, relax, it won't hurt anything to run it that way. Be careful flashing the bios. Here's some links: http://www.foxconnsupport.com/inquiry.aspx

Bios file p07 may also work with your cpu, but increases the ram voltage to 1.8 when you set the ram speed manually. That's why I requested the new bios file from foxconn tech support.
