i want to lower he cost of my custom pc, and i know of two motherboards that are the same except for the RAM. DDR2 ram is cheaper, so i am leaning toward that. but will it make a difference if i get DDR2 instead of DDR3? What's the difference?

Thanks.

EDIT: Also, if i use this motherboard ( http://www.newegg.com/Product/Produc...82E16813128395 ), it says it needs ddr2 240-pin 1333 RAM. would i work if i used DDR2 667 (PC2 5400)??

DDR3 RAM isn't worth it unless you are running a new Core i7 system. I don't know if I would go all the way down to DDR2 667 RAM though. For 2GB sets, I would look at this or this . For 4GB sets, this or this .

the only reason to get DDR3 is if you are buying a new AMD board or you are buying a Core i5/i7 board.


DDR3 on a Core2 is just a total waste of money. The FSB (even the fastest 1600FSB) is saturated by lowly DDR2-800 in dual channel (that and there is a lot of cache coherency traffic on a Core2Quad).

just note that DDR3 must be used with a motherboard that supports DDR3. They support DDR2 or DDR3, but not both.


A Phenon II CPU can support either DDR2 or DDR3, though, depending on the motherboard it is plugged into.

alright. thanks!

one more question, if i get a 512mb geforce 8600 gt (found one for $60), it says it has ddr2 sdram, does that mean it won't work with a motherboard supporting ssr3?

No. It should work just fine as long as you have a free PCI-E 16x slot.

This card is way better than an 8600GT, and it's only about $40 after MIR.
