Hardware: Tyan S2696 mobo 2 x 2GB DDR2 PC-5300 667 MHz FB-DIMM 2 x Xeon X5355 the rest is irrelevant I hope Software: Vista Ultimate 32-bit CPU-Z 1.46 I get the following results: Why is my memory speed reported as 332.6 MHz? Is CPU-Z fooled by FB-DIMMs? I see no mention of that in the readme. Vista's Windows Experience Index reports the memory as a 4.7, for whatever that is worth.
I think you are asking why its 333 not 667. Its DDR, therefore 333 IS 667 as its double data rate. So while its running at 333 (or 332.6) its effective speed is 667.
