I have a HP slimline model s5123w. It came with 3 GB of ram and I would like to know how to find out what the max amount of ram the computer will accept. This computer was a gift so its not my first choice, so I'm kind of stuck with it. I want to take out the 3 Gb of ram thats in it now and upgrade it to the max amount the mother board will allow. The mother board only has two slots for ram and I know most computers will only accept a certain amount of ram,so if some one can tell me how to find out what that amount is I would be greatfull. I would also like to upgrade the video card, but from what I've read theres not very many choices out there for this computer because of the small case and power supply. But if any one knows of a specialty card, please let me know.malonemarshall071@gmail.com
