NOTE: Only socket AM2+ processors are supported with this motherboard.
It's an AM2+ board (which apparently will only
use AM2+ CPU's), so it should
AMD Phenom II Quad-Core
AMD Phenom II Triple-Core
AMD Phenom Quad-Core (A) 9xxx series (AM2+)
AMD Phenom Triple-Core (T) 8xxx series (AM2+)
AMD Athlon X4
AMD Athlon X3
AMD Athlon X2 (B) (AM2+)
That's what should work, and the X4 9650 falls into that category.
Also, any 95W AM2+ PII CPU's should work too.
