1.7.2 Memory Configurations
You may install 64 MB, 128 MB, 256 MB, 512 MB and 1 GB unbuffered ECC or non-ECC
DDR DIMMs into the DIMM sockets using the memory configurations in this section.
y IF you installed four 1GB memory modules, the system may detect less
than 3GB of total memory because of address space allocation for other
critical functions. This limitation applies to Windows XP 32-bit version
operating system since it does not support PAE (Physical Address
Extension) mode.
y IF you install Windows XP 32-bit version operating system, we
recommend that you install less than 3GB of total memory.
y For dual-channel configuration, the total size of memory module(s)
installed per channel must be the same for better performance (DIMM_A1
+DIMM_A2=DIMM_B1+DIMM_B2).
y When using one DDR DIMM module, install into DIMM_B1 slot only.
y When using two DDR DIMM modules, install into DIMM_A1 and
DIMM_B1 slots only.
y 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 memory Qualified Vendors List on the next
page for details.
y Due to CPU limitation, DIMM modules with 128 Mb memory chips or
double-sided x16 memory chips are not supported in this motherboard.
