2.3.2 Memory Configurations
You may install 2GB, 4GB, 8GB, and 16GB RDIMMs or 2GB, 4GB and 8GB* with
ECC/Non-ECC UDIMMs or 8GB, 16GB and 32GB* LR-DIMMs into the DIMM
sockets using the memory configurations in this section.
Always install DIMMs with the same CAS latency. 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.
You may install varying memory sizes in Channel A, Channel B and
Channel C. The system maps the total size of the lower-sized channel for
the dual-channel or triple-channel configuration. Any excess memory from
the higher-sized channel is then mapped for single-channel operation.
Due to the memory address limitation on 32-bit Windows OS, when you
install 4GB or more memory on the motherboard, the actual usable memory
for the OS can be about 3GB or less. For effective use of memory, we
recommend that you do any of the following:
- Use a maximum of 3GB system memory if you are using a 32-bit
Windows OS.
- Install a 64-bit Windows OS when you want to install 4GB or more on
the motherboard. For more details, refer to the Microsoft ® support site
at http://support.microsoft.com/kb/929605/en-us.
This motherboard does not support DIMMs made up of 256 Mb (32MB)
chips or less (Memory chip capacity counts in Megabit, 8 Megabit/Mb = 1
Megabyte/MB).
