Need help finding RAM for PC


My parent's current PC is this (with a 600W PSU and HD 6750):

One stick of RAM went bad (not sure of the cause; might have been when I re-seated it and static killed it or something like that). I'm not sure what RAM to get now. The previous RAM was I think Samsung Green Memory. Anyway, what RAM will work on the MoBo? I want to keep the other stick, but f I have to, I am willing to remove it. If I can keep it, can anyone find my a stick of 4GB RAM which will be supported (for a total of 6GB)? Or at least a pair of dual channel RAM (2x2GB) if i have to remove it?


The link you posted for the PC you have shows that you can use up to 4 GB. DDR3 1066/1333 RAM on a 32 bit O/S and 16 GB. on a 64 bit O/S. Any Phenom II approved RAM should work so I'd buy ONE matched, tested RAM Kit consisting of 2x 2 GB. DIMMs if you have a 32-bit O/S or One RAM Kit of 2x 4GB. if you are using a 64-bit O/S. The link below should help. Make sure the RAM kit you select is approved for use with AMD Phenom II CPUs. Do not mix the new and old RAM. Use just the new RAM kit.
