2.3.1 Overview
The motherboard features eight fully-buffered DIMM (FB-DIMM) sockets to support
240-pin FB-DIMM modules. You can purchase extra FB-DIMM modules based on
your needs. An FB-DIMM module has a different pin-out from DDR2 DIMMs so
you cannot install DDR2 DIMMs on an FB-DIMM socket. Note that an FB-DIMM
socket has an Advanced Memory Buffer (AMB) chip that allows memory-to-CPU
connection at gigabit speed.
The figure illustrates the location of the FB-DIMM sockets:
