ASUS DSBF-DE Series

2.4 System memory
2.4.1 Overview
The motherboard comes with eight 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 gure illustrates the location of the FB-DIMM sockets:
2.4.2 Memory congurations
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 Qualied Vendors List on the ASUS
web site.
This motherboard does not support memory modules made up of 128 Mb
chips 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.
