2x CMSO8GX3M1A1333C9


Recommended Posts

Hi, I purchased 2 x CMSO8GX3M1A1333C9 (8GB SODIMM 1333Mhz) for a 8560W


1.- The 8560W already 2x 4GB with the same timings.

2.- I added the 2 x CMSO8GX3M1A1333C9 and it wouldn't boot

3.- I swapped out the 2x4GB for the 2xCMSO8GX3M1A1333C9, wouldn't boot.

4.- Tried 1 by 1, no problem.

5.- Changed the order of the CMSO8GX3M1A1333C9 boot.


So if one of the CMSO8GX3M1A1333C9 is in either slot 1 or 3 and there's another used slot it won't boot.


What's the deal with that?

Have you checked with the system manufacturer to be sure it will support memory made with 512M X 8 Memory IC's? Do you have the make and model number of your system? Listing it as 8560W is to generic sorry!

I bought 2xCMSO8GX3M1A1333C9 we'll call them A and B.


A works:

1.- By itself

2.- With the other 2x4GB dimms in any combination


B works:

1.- By itself

2.- In slot 2 or 4 when A is in 1 or 3


B does not work (computer won't boot):

1.- in combination with either of the 4GB modules

2.- in slot 1 or 3
