Answer 3

if you are unsure on what type of ram you have turn off your computer and take out the ram... be sure not to chip anything, (for obvious reasons) once you have take out your ram (you only need to take out one stick) check how many gaps it has usualy if it only has one gap it's DDR and is on a later model of computer otherwise if the computer is older than about 3-6 years you could be using SDRAM which usualy has 2 gaps... buf if what your saying is correct than you have DDR and should DDR for PC's ddr ram usualy fits in any later model computer and once again depending on how old your computer is you can get from 126mb - 2gigs of ram (2x1gig) ... well i hope that helped in someway

Answer 5

Call Best Buy. Give them the name and model number of your computer. They will advise you what to buy. You can install it yourself. The bigger the better is certainly true in RAM.
