Memory
The MPCBL0050 MCH supports four Fully-Buffered DIMM (FB-DIMM) memory channels.
FB-DIMM memory utilizes a narrow high-speed frame-oriented interface referred to as
a channel. The four FB-DIMM channels are organized into two branches of two channels
per branch. Each branch is supported by a separate Memory Controller (MC). The two
channels on each branch operate in lockstep to increase FB-DIMM bandwidth. A branch
transfers 16 bytes of payload/frame on Southbound lanes and 32 bytes of payload/
frame on Northbound lanes. Each FB-DIMM module, in addition to DRAM chips,
contains an Advanced Memory Buffer (AMB) device that is responsible for
communication between an FBDIMM memory module and MCH over the FBDIMM
channel. See
Fully Buffered DIMM channels
The key features of the MPCBL0050 FB-DIMM memory interface are:
On the MPCBL0050, each FBDIMM channel provides 1 GB/s throughput. Full memory
bandwidth of 4 GB/s can be achieved only by populating all four memory slots.
• Four Fully Buffered DDR (FB-DIMM) memory channels.
• Branch channels paired together in lockstep to match FSB bandwidth requirement.
• Support for up to 4 dual-ranked FB-DDR2 4GB DIMMs (16GB of physical memory)
(up to 4GB)
