Hello All!

Just wanted to know what the differences are between these types of memory:

DDR
DDR2
Dual Channel DDR
Dual Channel DDR2

What are the the advantages/disadvantages of each? What are the differences? Is there any website you can link me to so I can read more about them? Perhaps some comparison testing review sites?

Any info is appreciated. Thanks.

DDR2 is faster than DDR basically. Not sure about Dual Channel though.

DDR is the most common memory out there right now, it's pretty much your basic RAM. (Right now, anyway)

Dual Channel DDR is a feature of some motherboards that runs 2 identical sticks of DDR, and makes them act as one...you get a small performance boost, usually not noticeable except in benchmarks.

DDR2 is the next form of DDR, it's faster, and better, but not compatible with regular DDR, so if your motherboard only has support for DDR, you won't be able to use DDR2 because DDR2 sticks are bigger.

Dual channel DDR2 I'm guessing is the same as regular dual channel, except it uses DDR.

For reviews, check out www.tomshardware.com and www.anandtech.net, they'll probably have something on them.

...what he said. Your going to want to check your motherboard manual for what kinds it supports(ddr vs. ddr2, dual-channel vs. non, pc3200 etc., that kind of stuff).
