I could be wrong but IIRC, some MBs of that era require very specific DIMM timing parameters and/or require "registered" (buffered) DIMMs when populating all slots for dual-channel operation. Usually they are more tolerant when running only a single bank or not running in dual-channel. If you can find the manual, you might want to check that possibility. -- Clifton -- Clifton Royston -- cliftonr@iandicomputing.com / cliftonr@lava.net President - I and I Computing * http://www.iandicomputing.com/ Custom programming, network design, systems and network consulting services
