2.3 Memory Sub-system

The Intel

boards that use the Intel

5000 MCH support several fully-buffered (FBD) memory

modes of operation.

 Single-channel mode (single DIMM mode)

 Single-branch / dual-channel mode

 Dual-branch / dual-channel mode (four channels)

 Memory sparing mode

 Memory mirroring mode

The Intel

5000 MCH provides an integrated memory controller for direct connection up to four

channels routed to eight connectors supporting registered DDR2-533 and DDR2-667 FBDIMM

memory (stacked or unstacked). Each channel can support up to 2 Dual Ranked FB-DIMM

DDR2 DIMMs. FBDIMM memory channels are organized in to two branches for support of RAID

1 (mirroring). The MCH can support up to 8 DIMMs or a maximum memory size of 32 GB

physical memory in non-mirrored mode and 16 GB physical memory in a mirrored configuration.

The read bandwidth for each FB-DIMM channel is 4.25 GB/s for DDR2 533 FB-DIMM memory

which gives a total read bandwidth of 17 GB/s for four FBDIMM channels. Thus, this provides

8.5 GB/s of write memory bandwidth for four FB-DIMM channels. The read bandwidth for each

FB-DIMM channel is 5.3GB/s for DDR2 667 FB-DIMM memory which gives a total read

bandwidth of 21GB/s for four FB-DIMM channels. Thus, this provides 10.7 GB/s of write
