This is one possibility. Note POSSIBILITY. And only that.

You may have modules paired wrong, so that you have one module of each
type on the same channel (instead of having each channel comprised of a
pair of identical modules). Verify the configuration with the manual,
or TRY swapping two modules of different types.

Hi,

I'm trying to get the following memory modules running on my GA-EP35C-DSR3
board:
2 x 1 GB OCZ2G8002GK (Platinum Edition, PC2 6400, )
and
2 x 1 GB OCZP800R22GK (Gold Edition, PC2 6400, ).

The CPU is not over clocked nor the memory, however I'm getting some
strange CRC failures during the installation of e.g. large update files for
games in Windows XP Pro.

I've tested the memory with Memtest86 and all seems to be OK, at least no
errors where indicated.

Perhaps I've got some timing problems with this memory. When removing one
pair, all runs well!

Any advice if I can use those memory modules altogether on my board or
perhaps it isn't possible at all.
