I bought a Biostar Mobo 945GC-m4 specifically because it was a socket 478 and I had a 2.6 ghz cpu lying spare. Wanted a cheap system to play around with Linux distos. Nowhere on the box, or on NewEgg which is selling it, does it say CPU support is limited to 7 specific CPUs. Mine isn't one of them and the board won't post. The install guide says the board supports 3xxx CPUs. but their web site has specific part numbers listed. My question is, are all 478, 3.0 ghz CPU's created equal? Is the part number more related to where it was made than what internal architecture it runs?
