I have an AMD 5000 Black (socket AM2) and my motherboard doesn't allow me to adjust my voltage or ram timing's (something i'd like to do).I can't even push my HT passed 215mhz withount a lock up.I've used AMD Overdrive to get a stable 3.0Ghz (with stock voltage) overclock but i would like to do more.I realy would like crossfire support as i have a pair of cards.
