Im starting to rebuild my system : Asus M3A78, amd athlon 64 X2 7750 kuma powerd by a corsair 750 watt psu.

I am thinking about maxing out the ram to 8 gb just for grins, but have been out of the hardware scene long enough to have lost track.

As I look around im not seeing 4gb modules for ddr2 pc2 8500, am I missing something or are they just not available.
