3.HARDWARE SETUP

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) of 16, 32, 64, 128MB, or 256MB.

This chipset does not support ECC. However, ECC memory modules may still be used, but the ECC function will not be available.

Memory speed setup is recommended through SDRAM Configuration in 4.4.1 Chip Configuration.

Install memory in any combination as follows:

Location

168-pin DIMM SDRAM

DIMM1

Single-Sided

 

 

(Rows 0&1)

Double-Sided

(Rows 2&3)

Double-Sided (DIMM3 must be empty)

3.5.1 General DIMM Notes

•When this motherboard operates at 100MHz, PC100-compliant modules must be used because of the strict timing issues involved under this speed. If your DIMMs are not PC100-compliant, set the SDRAM bus frequency to 66MHz RAM but onboard graphics performance and PCI expansion cards will suffer tremendously.

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

•SDRAM chips are generally thinner with higher pin density than EDO (Extended Data Output) chips.

•BIOS shows SDRAM memory on bootup screen.

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