Memory configurations

You may install 256MB, 512MB, 1GB, and 2GB unbuffered ECC/non-ECC DDR2 DIMMs into
the DIMM sockets.
• You may install varying memory sizes in Channel A and Channel B. The system maps
the total size of the lower-sized channel for the dual-channel configuration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• Always install DIMMs with the same CAS latency. For optimum compatibility, we
recommend that you obtain memory modules from the same vendor.
• Due to the memory address limitation on 32-bit Windows
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:
-
-
• This motherboard does not support DIMMs made up of 256 megabits (Mb) or less.
The motherboard supports up to 4GB memory modules on Windows
and Vista x64 editions. You may install a maximum of 2GB DIMMs on each slot.

• Due to AM2+ CPU limitation, only one DDR2 1066 DIMM is supported per channel.
When two DDR2 1066 DIMMs are installed, all DIMMs run at 800Mhz frequency by
default for system stability.
• The default DIMM frequency depends on its Serial Presence Detect (SPD), which is the
standard way of accessing information from a memory module. Under the default state,
some memory modules for overclocking may operate at a lower frequency than the
vendor-marked value.
