    I have 2x ddr 800 sticks.
    A ma770-ud3p Gigabyte Motherboard.

    I have an AMD 7850 Athlon x2 running 2.8ghz on a 14x multiplier.

    Everything is stock, afaik the math should be:

    200 (host clock) x 14 = 2800Mhz

    Which means the ram calculates out to:

    2800/7 = 400 (which fits with ddr2 800 due to dual data rate)

    However what appears to be happening is 2800/14 = 200 (which means my ddr2 800 is FSB limited)

    Can anyone lend me a hand?
