1.4System memory

1.4.1Overview

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:

DIMM A1

DIMM A2

DIMM B1

Channel A

DIMM_A1 and DIMM_A2

 

 

Channel B

DIMM_B1 and DIMM_B2

 

 

1.4.2Memory configurations

You may install 256 MB, 512 MB and 1 GB unbuffered non-ECC DDR DIMMs into the DIMM sockets using the memory configurations in this section.

¥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 builderÕs 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.
