System memory

2.4.1

Overview

The motherboard comes with sixteen fully-buffered DIMM (FB-DIMM) sockets to
support 240-pin FB-DIMM modules. 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:

You may install 512 MB, 1 GB, 2 GB, 4 GB, and 8 GB registered ECC FB-DIMMs
into the DIMM sockets.

For optimum compatibility, we recommend that you obtain memory modules
from the same vendor. Refer to the Qualified Vendors List on the ASUS
web site.
The FB-DIMM 800 MHz has to work with the 1600MHz FSB CPU or above;
otherwise the memory module downgrades and runs at the speed of
667MHz.
If you are installing only one memory module, install into the white socket
labeled DIMM_00. Installing into any other socket will not work.
