hello folks,

I am planning to upgrade my PC's ram. currently the ram I have is 2x256MB=512MB/133MHz (DDR266) - DDR SDRAM, PC-2100.

My guess is that it has 184 Pins.

I would like to get a DDR2 with 667MHz, 240 pin. Is it possible, since pins don't match. Do they have to match? (there are 3 slots on motherboard for DDR)

regards
