i built my computer myself so it is no one kind. if you need to know what kind of memory you need, just open your computer up with it unplugged and look at one of your memory modules/sticks and the information will be printed on them. this is ddr2 pc 5300 memory
ok, i had to find a magnifying glass. i don't see too well. this is exactly what is on the sticker 1gb 128 x 64 -3, ddr2-667, pc2-5300 and down the side is the number 1152362. i don't see a manufacturer on the chip anywhere. i did find another number on the back B62URCE 1.00 BP ML E186014 94V-0. THAT'S IT I HOPE THAT HELPS.
