Hi all. My parents have a Dell Dimension 2400 pc that i recently just replaced the cpu in (the 2.4 celeron i think was making the system lock up after 5 minutes of use, installed an old 1.6 p4 and its fine now) The system only has 256mb ram and i was wondering if getting another 256mb module (ddr 333) to make 512mb ram would make much of a difference in performance. The system runs extremely slow as it has avg 8.5 running all the time. Plus it is running IE8 and MP11. So would 512MB ram improve the performance of the computer much? Building or buying a whole new computer is not an option (i tried to tell them that that is the better way to go, they would rather keep this one). I dont think my parents would be willing to pay the extra for 1gb ram either. Bit overkill for what they do anyway (web surfing and spider solitare is all it is used for). The system is running Windows XP Pro Service Pack 2.
