III. H/W SETUP System Memory III. HARDWARE SETUP 2. System Memory (DIMM) 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 to form a memory size between 8MB and 768MB. 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 in Chipset Features Setup under BIOS SETUP. Memory speed setup is recommended through SDRAM Configuration in Chipset Features Setup under BIOS SETUP. IMPORTANT! (see Notes below) • To make using bus speeds ≥95MHz possible, SDRAMs used must be com- patible with the current Intel PC100 SDRAM specification.. Install memory in any combination as follows: DIMM Location 168-pin DIMM DIMM1 (Rows 0&1) SDRAM 8, 16, 32, 64, 128, 256MB Total Memory x1 DIMM2 (Rows 2&3) SDRAM 8, 16, 32, 64, 128, 256MB x1 DIMM3 (Rows 4&5) SDRAM 8, 16, 32, 64, 128, 256MB x1 Total System Memory (Max 768MB) = NOTES • DIMMs that have more than 18 chips are not supported on this motherboard. • To make using bus speeds ≥95MHz possible, use only PC100-compliant DIMMs. Most systems will not even boot if non-compliant modules are used because of the strict timing issues involved with speeds ≥95MHz. • SDRAM chips are generally thinner and have higher pin density than EDO (Extended Data Output) chips. • BIOS shows SDRAM memory on bootup screen. • Single-sided DIMMs are available in 16, 32, 64, 128MB; double-sided in 32, 64, 128, 256MB.
