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 either 8, 16, 32, 64, 128MB, or 256MB.

The SiS 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:

DIMM Location	168-pin DIMM		Total Memory
Socket 1 (Rows 0&1)	SDRAM 8, 16, 32, 64, 128, 256MB	x1
Socket 2 (Rows 2&3)	SDRAM 8, 16, 32, 64, 128, 256MB	x1
Socket 3 (Rows 4&5)	SDRAM 8, 16, 32, 64, 128, 256MB	x1
	Total System Memory (Max 768MB)	=

3.5.1 VGA Shared Memory with DIMM

When using DIMM as shared memory for the onboard VGA, be sure that there is a DIMM inserted into DIMM socket 1.

3.5.2 General DIMM Notes

•For the system CPU bus to operate at 100MHz, use only PC100-compliant DIMMs. When this motherboard operates at 100MHz, 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 PC100-compliant, set the CPU bus frequency to 66MHz RAM to ensure system stability. NOTE: For motherboards that support asynchronous mode, set the memory bus frequency to 66MHz.

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

•Two possible memory chips are supported: SDRAM with and without ECC.

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

•BIOS shows SDRAM memory on bootup screen.
