Hardware Guide - DDR2

So what's next I here you ask ? Well along with the new motherboards comes DDR2. DDR2 is he next generation of memory sticks, starting off where DDR ended. Don't be rushing out to buy it if you have an older motherboard as it will not be compatible. 

Although released sometime ago this memory type is only now creeping into the main stream. The old DDR ran at 200/266/333/400 Mbps respectively, whereas the new stuff runs at 400/533/667 Mbps.

If you decide to go for the new PCI express compatible boards then this will be the memory of choice for you. Within no time you will have a killer system, which will run every program/game on the market as smoothly as possible.
