III. INSTALLATION System Memory III. INSTALLATION 2. System Memory (DIMM) Only Dual Inline Memory Modules (DIMMs) can be used with this motherboard. Three sockets are available for 3.3Volt (power level) Unbuffered Synchronous DRAMs (SDRAMs; 8, 16, 32, 64, or 128MB) or EDO DRAM (8, 16, 32, 64, 128, or 256MB) to form a memory size between 8MB to 768MB. One side (with memory chips) of the DIMM module takes up one Row on the motherboard. If ECC-supported DIMM is used, you can enable the ECC function through BIOS setup - CHIPSET FEATURES SETUP "Data Integrity Mode." IMPORTANT: You must first set the memory speed through the "EDO/FPM Configuration" under the BIOS Chipset Setup of the BIOS SOFTWARE. Install memory in any combination as follows: DIMM Type 168-pin DIMM Memory Modules Total Memory Socket 1 SDRAM 8, 16, 32, 64, 128MB x1 (Rows 0&1) EDO 8, 16, 32, 64, 128, 256MB Socket 2 SDRAM 8, 16, 32, 64, 128MB x1 (Rows 2&3) EDO 8, 16, 32, 64, 128, 256MB Socket 3 SDRAM 8, 16, 32, 64, 128MB x1 (Rows 4&5) EDO 8, 16, 32, 64, 128, 256MB Total System Memory (Max 768MB) = WARNING: Memory modules must have 18 chips or less. Memory modules with more that 18 chips will cause unstable operation. ASUS DIMM Module Examples: ECC EDO DIMM (9 chips) Non-ECC SDRAM DIMM (8 chips) General DIMM Notes: (not true for all memory modules) • Four possible memory chips are supported: EDO or SDRAM with and without parity. • SDRAM chips are generally thinner with higher pin density than EDO chips. • BIOS shows EDO or SDRAM memory on bootup screen. • 8 chip/side modules do not support parity, only 9 chip/side modules support parity. • Single sided modules are usually 16 or 64 MB, double sided are usually 8, 32, or 128MB.
