The system memory controller supports DDR2 and DDR3 (SO-DIMM only protocols) 
with one 64 bit wide channel accessing two DIMMs. The controller supports a maximum 
of two non-ECC DDR2 DIMMs or two un-buffered DIMMs, single or double sided; thus 
allowing up to four device ranks. Intel® Fast Memory Access (Intel® FMA) is 
supported.

The system memory controller supports only one memory organization mode: single 
channel. In this mode, all memory cycles are directed to a single channel.

The system memory controller supports the following DDR2 Data Transfer Rates, DIMM 
Modules and DRAM Device Technologies:

•

DDR2 Data Transfer Rates: 667 (PC 5300), non-ECC

— Rawcard C = single sided x16

— Rawcard D = single sided x8

— Rawcard E = double sided x8

•

DDR2 Data Transfer Rates: 800 (PC 6400), non-ECC

— Rawcard C = single sided x16

— Rawcard D= single sided x8

— Rawcard E = double sided x8

“Single sided” above is a logical term referring to the number of Chip Selects attached 
to the DIMM. A real DIMM may put the components on both sides of the substrate, but 
be logically indistinguishable from single sided DIMM if all components on the DIMM are 
attached to the same Chip Select signal.

•

x8 means that each component has 8 data lines.

•

x16 means that each component has 16 data lines.

There is 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. 

There is no support for 4Gb and 8Gb technology.
