I have a Phenom X4 9750
(Operating speed: Up to 2.4 GHz
Number of cores: 4
Bus speed: 3600 MHz HT3)
I have 8 gigs, four DDR2 SO-DIMM (240-pin), PC2-6400 MB/sec
My mobo shorted out a month or so ago from a faulty power supply. Wasn't too bad, no smoke or weird things, just simply stopped working, won't even roll over or blue screen.
