Channel A DIMM_A1 and DIMM_A2
Channel B DIMM_B1 and DIMM_B2
• 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).
• When using one DDR DIMM module, install into DIMM_B1 slot only.
• When using two DDR DIMM modules, install into DIMM_A1 and
DIMM_B1 slots only.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommended that you obtain memory modules
from the same vendor system builder’s website for the latest
qualified vendors list (QVL).
• Due to chipset resource allocation, the system may detect less than
4 GB of system memory when you installed four 1 GB DDR memory
modules.
• Due to CPU limitation, this motherboard does not support DIMM
modules with 128 Mb memory chips or double-sided x16 memory
chips.
