or any of the AMD 64 bit CPU's can use DDR 2.
The reason is that in a billiant and great move at the time, they put the MCH [memory controller hub] inside the CPU chip. Now that people are going to DDR 2, AMD will have to create new CPU's. That isn't planned until mid 06 and then will require a new mobo.
But be sure to use Dual Channel mode for memory to get best performance [buy pairs of memory].
I was looking at getting some new ram and I see the DDR and the ddr2 ram - was wondering which was the fastest ram - I have a amd64 3000 / 939 / MSI neo4 motherboard - can either work in that setup. Thanks for any info - use the computer for games mostly
