Crucial recommends DDR2-667:

Actually, the proper RAM for an Athlon 64 X2 system is DDR2-800. Since the memory controller is built into the CPU, I don't see why DDR2-800 wouldn't work. DDR2-533 or DDR2-667 should also work, but there will be a slight performance hit.

Did you buy standard RAM that runs at 1.8v? If you bought so-called "gaming RAM" that requires 2.0v or higher, I suspect that is the problem.
