Memory configurations
You may install a 512MB, 1GB, and 2GB unbuffered non-ECC DDR2 DIMM into the DIMM
socket.
• 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.
• For dual-channel configuration, you can:
-
install two identical DIMMs in DIMM_A1 and DIMM_B1; or
-
install four identical DIMMs in all four slots; or
-
install one identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow slots) and
another identical DIMM pair in DIMM_A2 and DIMM_B2 (black slots).
• Due to the memory address limitation on the 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 either of the
following:
-
Install a maximum of 3GB system memory if you are using a 32-bit Windows
®
OS.
-
Use a 64-bit Windows
®
OS if you want to install 4GB or more memory on the
motherboard.
• This motherboard does not support DIMMs made up of 256 megabits (Mb) chips or less.
• This motherboard supports up to 8GB on Windows
indows
®
XP Professional x64 and Windows
®
Vista x64 editions. You may install a maximum of 2GB DIMMs on each slot.
. You may install a maximum of 2GB DIMMs on each slot.
• The default memory operation frequency is dependent 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.
• For system stability, use a more efficient cooling system to support a full memory load (4
DIMMs) or overclocking conditions.
