Added the Q8400 and the MB will not even boot. Any ideas?
My intel mobo DG33FB initially only supported only 1066 FSB quads [was even printed on the box]
After 2 years while i was updating to the latest bios , i went thru the list of added features, and it said that the mobo now supports 1333mhz quads, as well as half multipliers
just check on intel's website regarding whats included in the latest bios for ur mobo
Put your old processor back and upgrade to the latest available BIOS from the Intel website (or wherever available)..
I didn't even update the BIOS. Added the CPU (used to run on an old P4 CPU) and everything worked. I did update the BIOS to OC better much later on though, and it dramatically increased speed. I find it confusing.
