3.5System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory.

This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM). One side (with memory chips) of the DIMM takes up one row on the motherboard.

Memory speed setup is recommended through SDRAM Configuration in 4.4.1Chip Configuration.Install memory in any combination as follows:

DIMM Location

168-pin DIMM

 

Total Memory

 

 

 

 

Socket 1 (Rows 0&1)

SDRAM 8, 16, 32, 64, 128, 256, 512MB

Socket 2 (Rows 2&3)

SDRAM 8, 16, 32, 64, 128, 256, 512MB

CAUTION! If the total installed memory exceeds 512MB, the system will hang during startup.

3.5.1 General DIMM Notes

•For the system CPU bus to operate at 133MHz, use only PC133-compliant DIMMs. When this motherboard operates at 133MHz, most system will not even boot if non-compliant modules are used because of the strict timing issues involved under this speed. If your DIMMs are not PC133-compliant, set the CPU bus frequency to 100MHz RAM to ensure system stability.

•ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the memory of choice for best performance vs. stability.

•BIOS shows SDRAM memory on bootup screen.

•Single-sided DIMMs come in 16, 32, 64,128, 256MB; double-sided come in 32, 64, 128, 256, 512MB.
