rklesla Posted December 28, 2005 Share Posted December 28, 2005 I bought about a year ago a corsair stick XMS2 that is 512MB. I wanted to buy another one to dual channel it, so I decided to look around. My current memory module says the part number is: CM2X512-5400C4 675MHZ However every single module I see on the net is 667MHZ. Is there a reason why mine says differently? Which module should I buy then to make dual channel work? Thanks, Rklesla Link to comment Share on other sites More sharing options...
RJLeong65 Posted December 28, 2005 Share Posted December 28, 2005 Actually, the "675MHz" rating on your sticks is rounded. DDR2-667 memory is technically "PC5333" - but marketers like the "PC####" ratings in even hundreds (as in "PC##00"). And yes, you can add another stick of CM2X512-5400C4 - but make sure that the revision number is the same as your current stick, and the lot number is very close to that of your current stick.

rklesla Posted December 28, 2005 Author Share Posted December 28, 2005 Thanks for the info. When I buy these sticks with same part number and they say 667MHZ is, that basically saying 675MHZ, because it rounds up then? Thanks, Rklesla Link to comment Share on other sites More sharing options...
