System Memory

This motherboard uses interleaved PC133 Dual Inline Memory Modules (DIMMs).
Six DIMM sockets are available for 3.3Volt (power level) registered Synchronous
Dynamic Random Access Memory (SDRAM) of 16MB, 32MB, 64MB, 128MB,
256MB, 512MB, or 1GB densities with Serial Presence Detect (SPD) and Error
Check and Correction (ECC).
The motherboard supports system memory of up to 6GB in a two-way interleaved
configuration. This configuration requires that you install identical DIMMs (exactly
the same type and size) in pairs. For example, if you installed a 512MB module into
DIMMA1, you must install the same type of 512MB module into DIMMB1. The
same rule applies to pairs DIMMA2/DIMMB2 and DIMMA3/DIMMB3.
The following table lists the DIMM socket pairs and the memory modules you can
install.

3.5.1 Memory Configurations

DIMM Socket
DIMMB1 SDRAM 128MB, 256MB, 512MB, 1GB
DIMMA1 SDRAM 128MB, 256MB, 512MB, 1GB
DIMMB2 SDRAM 128MB, 256MB, 512MB, 1GB
DIMMA2 SDRAM 128MB, 256MB, 512MB, 1GB
DIMMB3 SDRAM 128MB, 256MB, 512MB, 1GB
DIMMA3 SDRAM 128MB, 256MB, 512MB, 1GB
IMPORTANT:
The system chipset only supports 64Mbit, 128Mbit, and 256Mbit
"registered" SDRAMs with ECC. Make sure to use only the specified DIMM
types for smooth system operation.
