AM2 officially supports DDR2-800.

"Before February, the plan was to support all memories up to DDR 667 but AMD eventually decided that it can and will support DDR 2 800 MHz from the outset. Now the migration to DDR 2 finally makes sense, as DDR 2 800 MHz can sure show sume difference compared with DDR 1 400 or even DDR 1 overclocked to 667.

It will simply offer more bandwidth and knowing that AMD places its memory controllers on the CPU it also means that it will show a bigger difference than Intel's DDR 2 capable chipsets. "
