DDR Progress .........

hardocp.com
There will be two different varieties of DDR modules, Registered and Unbuffered.

The Registered modules will primarily go into workstation/server boards. IBM is taking the lead in designing the first modules, working with Reliance, which will have the first Server chipsets. Sample modules will probably appear right around the first of the year. Production is not expected until 3rd quarter of 2000. Interestingly, a special high end version of this module will likely be introduced. This version will contain additional devices called "bus switches". The bus switches allow the modules to be isolated from the system bus, reducing the capacitive load. This will enable many registered DDR modules to share the same bus in extremely high end servers.

Micron is taking the lead in introducing the very first unbuffered DDR modules for desktop boards. Via is introducing the first chip set with samples appearing very soon. I would not expect production until mid to end of first quarter.

In both cases, the first devices will use 100 MHz SDRAM's modified to transfer data on both edges of the 100 MHz clock signal (in other words 200 MHz data transfer). 133 MHz devices will follow with data transfer rates of 266 MHz.

As you would expect, Corsair intends to be a supplier of DDR modules.

This is no doubt gonna be the schiznit when it arrives. Rambus my ass... Our thanks to the guys over at Corsair Memory, they rock the house, and their memory is pretty damn good also. I happen to have 256 Megs kicking in my box right now.
