Do what thinbear suggests, it is the most fail safe approach.
I've personally never had a RAM compatibility issue myself (my old Compaq Presario upgraded from 2x 512MB to 2x 512MB + 2x 1024MB perfectly fine, and this computer is using 2x 2048MB modules from Corsair), the only time that my computer beeped with the RAM failure error code was when I tried to overclock the RAM from 800MHz effective to 1066MHz effective.
