Urgent - What memory speeds for Athlon X2 4200?

Posted on 2006-05-25
Last Modified: 2013-11-10
I've suggested to my friend that he gets Corsair 2GB DDR2 XMS2-6400C4 TwinX (2x1GB) memory for his new build PC, but he's going Athlon X2 4200 and I'm normally an Intel man. I've got myself in a bit of a panic that I might have suggested he buy memory that's just too darned fast for an Athlon (Giving that the CPUs run at slower clock speeds).

Have I done a silly? What speeds are suitable?

    Most Athlon boards I've seen don't support DDR2 - just DDR.  What board does he have (I was just looking over this for an Athlon X2 3800+ I bought less than a month ago and I don't recall seeing any boards that supported DDR2.

    Yes, the Athlon64 cpus do not support DDR2 at the moment.  You will have to wait for the AM2 socket cpu to come out before that happens.  Fast PC3200 RAM is more than sufficient; the HyperTransport bus works internally in the cpu.

    He's getting the Asus A8N-SLI Premium:

    It says dual-channel DDR400. 6400 would be 800, I guess (been a while since I built, and never done an AMD)

    AMD only uses DDR becasue mem speed is slower.

    Here are some FAQ's about DDR2 vs DDR

    Hope this helps

    The specs on that board clearly state:
    4 x DIMM, max. 4GB, DDR 400/333/266, ECC, non-ECC, un-buffered memory
    Dual Channel Architecture

    How's about Corsair 2GB DDR XMS3200C2PT TwinX (2x1GB) CAS2? Sounds right...
