Is it possible to use 2 different kinds of ram(ddr2 and dimm) on a motherboard?

Question

Will they be compatible to run on a motherboard supporting 2gb of memory? Will there be any effect on the system performance or any other components?

Answer 1

A DIMM, or dual in-line memory module, can be any of the following:

SDR SDRAM

DDR SDRAM

DDR2 SDRAM

DDR3 SDRAM

for more information please post make and model of the mainboard and memory you want to use.

edit: the specs are pretty clear on the typ of memory the can be used with your mainboard:

• Dual Channel DDR2 memory technology
• 2 x DDR2 DIMM slots
• Supports DDR2 800/667 non-ECC, un-buffered memory
• Max. capacity of system memory: 8GB*

that means you can either use 2x 667 MHz or 2x 800 MHZ DDR2 memory, and no you can't mix them.
