SDRAM verses RDRAM

[jh3463]

I read, briefly somewhere (and I can find it again), that there is a new RAM either, coming out or is out, called RDRAM. Does anyone know anything about it? If my motherboard takes SDRAM can it still use this new RDRAM? Is RDRAM something that I should think about getting?
Aslo, I was looking at motherboards in a magazine and one in particular stated that it uses DDR memory only. I don't even have the slightest clue as to what DDR stands for. Is there anyone that can, in very simple terms, explain it to me Thanks as always people. Microsoft has nothing on the brain power in this forum

DDram is dual data rate.Meaning it is double the speed of Sdram.Sdram uses 168 pin configuration while Ddram uses 184 pins.So your motherboard must be able to support it to use it.

I don't know much about Rdram(it is also called rambus).I do know it is the fastest and most expensive type of ram.It is being used with Pentium 4 processors and Intel 850 chipsets.It is the best setup for the P4.

The new Intel chipset is the 845,but it only supports DDram so far(as well as Sdram)depending on the motherboard.

Woodys right as usual.Rambus is used for Intels P4 chips but the cost is to high so they will be offering DDR memory soon too.Some motherboards can support either sdram or ddr memory
it depends on your mobo setup but I'm not to sure if they can be on the same board together depends on whether they are registered/buffered.
