OverviewOverview

Overview

The motherboard comes with four 184-pin Double Data Rate (DDR) Dual

Inline Memory Modules (DIMM) sockets.

The following figure illustrates the location of the sockets:

•

For dual-channel configuration, the total size of memory module(s) installed

per channel must be the same for better performance

(DIMM_A1+DIMM_B1=DIMM_A2+DIMM_B2).

•

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 DDR400 Qualified Vendors List on the

next page for details.

• 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 chipset limitation, this motherboard does not support DIMM

modules with 128 Mb memory chips or double-sided x16 memory chips.

• With the 4 DIMM slot, the DIMM slots DIMM_A2 and DIMM_B2 are always to

be populated in pairs.
