TW3X4G1333C9 low density and is it compatible?


Recommended Posts

Not easy to find much info. on P.N. CM3X8GX3M4A1333C9. it appears to be a 2 x 1 GB. with similar timings compared to the 4 GB., (2 x 2 GB.), TW3X4G1333C9.


The second part number is approved for both Intel and AMD systems.


CM3X8GX3M4A1333C9 might be 2 gb because the qvl list reports it as 2gb module. It's also double sided so it has more chances of being a 2gb stick.

NEW Memory Part Number Breakdown


The part number's gotta be a typo on their QVL. Should be CMX, not CM3X. It's an 8 GB kit consisting of 4 x 2 GB sticks.


Note that it's not listed here: Guaranteed-Compatible Memory for your Gigabyte GA-880GM-UD2H


or here: http://www.corsair.com/products/phenomii/default.aspx


CMX8GX3M4B1333C9 and CMD8GX3M4A1333C7 are listed on the 2nd link however.

You guys the reason why i am soo worried about this is because TW3X4G1333C9A isn't compatible with my mobo but the tech guy said TW3X4G1333C9 should be compatible with my mobo because my mobo can't use high density ram? He said something along those lines.


I bought my kit from tigerdirect, it had problems so i rma'd for the same kit and those also had problems so now the tech guy told customer service to ship me TW3X4G1333C9 instead of the TW3X4G1333C9A.


Notice the only difference is the A...


isn't the only difference between TW3X4G1333C9DHX and TW3X4G1333C9 is the heatsink used?


I just want some stable memory !!!!
