- Okay, I have 2 x 256 (equaling a total of 512 DDR/PC3200/184 pin) memory modules in my PC right now and I have 2 open slots…

- I was wondering if I _ **have** _ to put 2 more 256 modules or could I instead put 2 x 512 (1024 DDR \<-- **which is what I want to do** ) with my 2 x 256’s? Basically, do I have to use 256-type memory since I already have 256 in my PC or does that not matter?

- I have a feeling that it doesn’t matter, but I wanted to be sure.

- Thanks.
