Advice on replacing 1GB stick of RAM with 2GB

I am wanting to replace one of the sticks of RAM on my computer with a 2GB stick for a total of 3GB. I have 32-bit version of Windows 7. This is what I have currently installed:

Crucial 2GB (2 x 1GB)

on this motherboard:


Would like to know which memory would cause trouble:

Kingston ValueRAM 2GB


The main reason for this is that I'm trying to run Star Wars: The Old Republic but run constantly into single digit frame rates. My graphics seems to suffice, but even at low settings I get crappy FPS.

Sapphire Radeon HD 5670 512MB

Somewhere I read that increasing the amount of RAM to 3GB+ would greatly help, and I believe it will. One reason is that when loading and exiting the game (particularly exiting), it takes several minutes. For example when exiting, it'll take at least about 5 minutes, which I'm guessing it's because it's deallocating that memory.

  1. Either one will work since they're both DDR3-1333.

    Either would work, but you would be running in single channel mode. Run your memory modules in matching pairs to take advantage of the dual memory controllers. The Corsair XMS 4GB (2x2GB) kit below is $18 after rebate.

    Or if you don't want to deal with a rebate.. GSkill 4GB (2x2GB) for $21...

    Having a 32bit OS will hinder you a bit by only using 3.5~GB, but you stay in dual channel mode.

  4. I wasn't exactly sure how much memory the 32-bit version could address. I don't care if it can't address the full 4GB, so long as I get more RAM available. I won't be able to use that last 0.5GB but I'll still be gaining 1.5GB of memory.

    Thanks a lot to both of you.
  5. Windows 32bit recognizes 2GB of ram while 64bit recognized 4GB or more. It never hurts to have more ram with the low prices at the moment.
