hey my first post here and i can actually help someone

try www.newegg.com for all your computer up grade needs.......

i USUALLY build 3-4 PCs a year and they get 99% of my business

do you know which TYPE of memory you need??

if not go here http://www.cpuid.org/cpuz.php

when you run that program (its free) click on the "memory"tab and it will list the TYPE of memory you currently have........

just buy the same stuff.........type and speed

any questions please feel free to ask

crucial AND kingston both make EXCELLENT ram

OCZ is another good brand

with RAM to a certian extent you get what you pay for.....however if youre not overclocking and really pushing the envelope any decent brand will perform about the same for you
