• For dual-channel conguration, the total size of memory module(s) installed
per channel must be the same (DIMM_A1 + DIMM_A2 = DIMM_B1 +
DIMM_B2).
• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from the
same vendor. Visit the ASUS website at www.asus.com for the latest DDR2
Qualied Vendors List.
• Due to chipset resource allocation, the system may detect less than 8 GB
system memory when you installed four 2 GB DDR2 memory modules.
• The motherboard can support up to 8 GB on the operating system listed
below. You may install a maximum of 2 GB DIMM on each slot.
