DRAM Technologies and Organization
"Single sided" below is a logical term referring to the number of Chip Selects attached
to the DIMM. A physical DIMM may have the components on both sides of the
substrate, but be logically indistinguishable from a single sided DIMM with all devices
on one side if all components on the DIMM are attached to the same chip select
signal.
x8
means that each component has 8 data lines.
means that each component has 16 data lines.
x16
All standard 256-Mb, 512-Mb, and 1-Gb technologies and addressing are supported for
x16 and x8 devices.
For DDR2
533 (PC2 4300)
Non-ECC
Version A = Single sided x8
Version B = Double sided x8
Version C = Single sided x16
667 (PC2 5300)
Non-ECC
Version C = Single sided x16
Version D = Single sided x8
Version E = Double sided x8
800 (PC2 6400)
Non-ECC
Version C = Single sided x16
Version D = Single sided x8
Version E = Double sided x8
No support for DIMMs with different technologies or capacities on opposite sides of the
same DIMM. If one side of a DIMM is populated, the other side is either identical or
empty.
Supported components include:
For DDR2 at 533 (PC2 4300) and 667 (PC2 5300)
