Memory Confusion


Recommended Posts


I have a problem with my PC randomly freezing and sometimes even automatically rebooting. Among other things I ran memtest and it passed without errors. However, I still think there's something odd about the installed memory that I found out (I didn't build the PC myself).

The first thing is that CPU-Z/SPD shows CM3X2G1333C9D as the part#. I can't find anything like this on the Corsair site.

Second, on the memory module it says: Dominator, TW3X4G1333C9D. Again, I can't find a module with exactly this description either.


Questions: Why is there a discrepancy between what the label shows and what the SPD info says? How am I able to verify if I have compatible memory modules if I can't find either one of the names on the Corsair web site?


The third thing is that the installed memory says 4GB(2x2). However I got 3 of those modules. But shouldn't I have something like 6GB(3x2)? Do I have the wrong memory modules and is this causing my random crashes?


Totally confused right now !

Thanks for help

CM3X2G1333C9D = STICK part number (not for sale by itself)

TW3X4G1333C9D = KIT part number


When you bought the pre-built kit, did they specify the memory kit number?


Sounds like they may have just taken memory sticks from separate kits and not used ONE kit.

Thanks for clarifying the stick/kit thing.


Just for clarification up-front, I didn't build the PC myself, but configured it instead at Cyberpower (I ordered 6GB tri-channel Dominator, no kit# was available). So I'm trying to figure out what's causing my problems. The reason I'm here in this forum is because Cyberpower's support is absolutely worthless (and that's a friendly description!)


Now, it seems that the TW3X4G1333C9D Kit is no longer available, as it is not shown on the Corsair website. However I googled it and found that it is a dual channel 4GB Kit. So you're right, they added just another stick from a different kit to make it a 6GB tri-channel package. Is this something that can cause the problems I have, like totally random system freeze? Or is it OK to mix and match?


In addition I can't find this kit on the QVL for my mobo either.


Would it be better to get a 6GB(3x2) kit instead and see if the problem goes away?


Thanks again.
