I know what it is but could someone fill me in as to which chip uses it or if both are? Is it out for amd or intel? What boards support this?

Intel: Granite Bay, SiS 655. (chipsets)
AMD: nForce and nForce2. (chipsets)
I have a question: Does DDR 400 = DCDDR?
DDR400 equals a maximum of 3.2GBs to the processor.Quote:

DC DDR PC2100 (DDR266) allows two seperate channels (a pair of sticks) at 2.1GBs or a total of 4.2GBs maximum, which is similar to Rambus PC1066 which runs the same.
EDIT: This maybe of interest to you.

THe original nForce was DCDDR?Quote:

Yes, but the performance was poor compared to VIA chipset boards and the chipset in general was extremely picky about what memory would and would not work, especially in DC mode.Quote:

yes. The major reason behind DC DDR is for the intergrated GPU. This allows better on-board graphics to be used.
For the nForce boards yes. For Intel, the DC DDR is to supply the 4.2GB of bandwidth the P4 was designed around.Quote:

At stock speeds, it's very close to RDRAM performance.
So which of the two is better to go with for an intel system, rdram or dc ddr?
RDRAM still out performs DC DDR at stock speeds.
Most overclockers will go for the DC DDR or wait for the Springdale chipset. DDR allows using a much higher FSB then people are reaching with a 850E RDRAM board, (about 150FSB for a RDRAM).
Here's a great look at Intel based chipsets,
Dual-Channel DDR SDRAM Arrives for the Pentium 4
Since Intel seemed to discontinue support for later RDRAM chipsets, many are going to DDR boards.
