III. H/W SETUP System Memory III. HARDWARE SETUP System 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. To utilize the chipset's Error Checking and Correction (ECC) feature, you must use a DIMM module with 9 chips per side (standard 8 chips/side + 1 ECC chip) and make the proper settings through Chipset Features Setup in BIOS SETUP. Memory speed setup is recommended through SDRAM Configuration under "Chipset Features Setup" in BIOS SETUP. 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) = NOTE: At the time this User's Manual was written, 256MB DIMMs are only available as registered memory. SPD Support This motherboard supports SPD DIMMs, and it is recommended that SPD DIMMs be used. General DIMM Notes • For the system CPU bus to operate above 100MHz, use only PC100-compli- ant 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 (FS) to 66MHz for system stability. • 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-sidedDIMMscomein16,32,64,128MB;double-sidedcomein32,64,128,256MB.
