Thanks mate for getting back, i will be honest with you, the info you have mentioned does not make much sense to me. i was understanding that moving over from 1gb to 2 gb of ram would instantly speed up my computer as i noticed the difference when moving from 512 to 1gb, i do have a nivida ge force fx 5500 graphics card and is running xp prof, a friend did build this computer around 3years + ago and since then over the years have upgraded the ram added pci cards etc,when i upgraded the ram i paid little attention to frequencys etc as lack of knowledge

i would like to make my computer better and faster and is learning all the time from people like yourself is the set up i have bad for my computer or making it disfunctional what would be your best advice.

thanks
