Memory Sub-system
2.1.1 Memory Sub-system
The MCH masters four fully buffered DIMM (FBD) memory channels. FBD memory utilizes a narrow high
speed frame oriented interface referred to as a channel. The four FBD channels are organized into two
branches of two channels per branch. Each branch is supported by a separate memory controller. The
two channels on each branch operate in lock step to increase FBD bandwidth. On the server board, the
four channels are routed to eight DIMM slots and are capable of supporting registered DDR2-533 and
DDR2-667 FBDIMM memory (stacked or unstacked). Peak theoretical memory data bandwidth is
6.4GB/s with DDR2-533 and 8.0GB/s with DDR2-667.

®
Server Board
S5000PSLROMB RAID Controller, and the Intel
®
Storage System SSR212MC2, a pair of channels
becomes a branch where Branch 0 consists of channels A and B, and Branch 1 consists of channels C
and D. FBD memory channels are organized into two branches for support of RAID 1(mirroring).
The server board supports up to eight DDR2-533 or DDR2-667 Fully Buffered DIMMs (FBD memory).
