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:

Memory configurations

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.
