first look at the inside cover of your system, the ram slot configurations should be posted on it

 

second, check the ram sticks, make sure the dimm model numbers match EXACTLY,  dimm numbers that are slightly diffrent mean the module IS DIFFRENT, and the diffrence could just be timings, or it could be the diffrence between 1/2/4 rank modules

 

3rd, you must be using a 64bit operating system to see/use more than 3/4 gigs

 

a 32bit os is limited to under 4gb, no way around it
