2-14 Chapter 2: Hardware information
2.4 System memory
2.4.1 Overview
The motherboard comes with six 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:
2.4.2 Memory configurations
You may install 256 MB, 512 MB, 1 GB, 2 GB, and 4 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.
• This motherboard does not support memory modules made up of 128 Mb
chips or double-rank x16 memory modules.
• If you are installing only one memory module, install into the white socket
labeled DIMM_00. Installing into any other socket will not work.
