Newer RAM on an old mobo?

  1. Hello everyone,

    I could have a nice deal for some 667 mhz RAM but I was wondering if it would work on my old motherboard - it's an Asus A8N SLI Deluxe, which says it supports up to 400 mhz.

    My question then becomes: would it work but clock at a reduced 400 or not work at all?

    Yes, but they will have to be normal DDR, not DDR2. DDR should have a 184 pin interface, and is actually somewhat of an antique, costing many times more than standard DDR2 with much lower performance.

    As a side note, ASUS boards tend to be marginally more temperamental about RAM choices, though there probably won't be a problem.

    Thanks for the quick replies guys!

    Hellokitty - I totally forgot to take that into account, it most probably is DDR2 so it won't even physically fit. Oh well, so much for 4 Gb for 20$... Time to get a new machine I guess! ;)

    Thats actually standard pricing for 4 (2 x 2) sets of DDR2 800, sometimes even 1066.
