3. HARDWARE SETUP 3.5 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 Ac- cess Memory (SDRAM) of 16, 32, 64, 128MB, 256 or 512MB. to form a memory size between 16MB and 1.5GB. One side (with memory chips) of the DIMM takes up one row on the motherboard. This motherboard also supports NEC’s Virtual Channel (VC) SDRAMs. To use the chipset’s Error Checking and Correction (ECC) feature, you must use a DIMM with 9 chips per side (standard 8 chips/side + 1 ECC chip).
Memory speed setup is recommended through Configure SDRAM Timing by SPD (see 4.4.2 Advanced Chipset Setup ). Install memory in any combination as follows: IMPORTANT For optimum signal integrity, inserting the DIMMs in the following order is recommended: DIMM1, DIMM2, DIMM3. SDRAMs used must be compatible with the current PC133/PC100 SDRAM specification. DO NOT attempt to mix SDRAMs with VCM SDRAMs. System Memory 3.
H/W SETUP Location 168-pin DIMM Total Memory DIMM1 (Rows 0&1) SDRAM 16, 32, 64, 128, 256, 512MB x1 DIMM2 (Rows 2&3) SDRAM 16, 32, 64, 128, 256, 512MB x1 DIMM3 (Rows 4&5) SDRAM 16, 32, 64, 128, 256, 512MB x1 Total System Memory (Max 768B) = 3.5.1 General DIMM Notes This motherboard supports SPD (Serial Presence Detect) DIMMs. This is the memory of choice for best performance vs. stability. This motherboard does NOT support registered memory. SDRAM chips are generally thinner with higher pin density than EDO (Ex- tended Data Output) chips. BIOS shows SDRAM memory on bootup screen. Single-sided DIMMs come in 16, 32, 64,128, 256MB; double-sided come in 32, 64, 128, 256, 512MB.
