I started out with 128 MB RAM in my PC when I bought it and then I added another 256 MB and never had a problem.
The only thing that confuses me a little is that when I open my System icon in Control Panel, it tells me I have 368 MB. 256+128=384...so why doesn't the extra 16 MB show up?
Will my computer improve performance beyond the 512MB ram if I leave the 256MB in the 1st DIMM slot, and just add the 512 to it??
Is that possible or does the ram in dimm slot 2 need to match dimm slot 1?
