The RAM is not compatible EDIT: with each other. This is very common when mixing memory modules. The same specs do not guarantee compatibility. Suggest that: you return the newly purchased RAM, and, if you want 2 GB, PURCHASE 'matched RAM' for dual channel - this will be 4 x 512 MB modules, or 2 x 1 GB modules, check your MB MANUAL. If you want 1 GB, use the 2 x Corsair or the OCZ, whichever you didn't return - just be sure that you install the RAM into the correct slots per the MB manual. Best of luck! EDIT: The MB spec that I looked at suggested that the board will only run PC3200 (400) SPEEDS for MSI CERTIFIED memory. May be an issue for you trying to run at 400 mhz. However, the difference between running at 366 v 400 is insignificant.

I just upgraded, I think, from 756mb ram to 2gig. I have a problem though.
