• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor. Refer to the DDR Qualified Vendors List at
the ASUS web site.
• Due to chipset resource allocation, the system may detect less than 16 GB
system memory when you installed eight 2 GB DDR memory modules.
• This motherboard does not support memory modules made up of
128 Mb chips or 256 MB double-rank x16 memory modules.
• Do not install double-rank and single-rank memory modules at the
same time.
• The server motherboard does not support installation of three or
five memory modules.
• If you are installing only one memory module, install into the blue socket
labeled DIMM_B4. Installing into any other socket would not work.
