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). 1 CPU Configuration (Required for CPU1) DIMM_A1 DIMM_B1 DIMM_C1 1 DIMMs P 2 DIMMs P P 4 DIMMs P P P DIMM_D1 P • *Refer to ASUS Server AVL for latest update. • Install the DIMMs starting from slot A1 (CPU1) and E1 (CPU2)..
