III. H/W SETUP System Memory III. HARDWARE SETUP 2. System Memory (DIMM) NOTE: No hardware or BIOS setup is required aftrer 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, or 128MB. 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 Socket 1 (Rows 0&1) Socket 2 (Rows 2&3) Socket 3 (Rows 4&5) 168-pin DIMM Memory Modules SDRAM 4, 8, 16, 32, 64, 128, 256MB x1 SDRAM 4, 8, 16, 32, 64, 128, 256MB x1 SDRAM 4, 8, 16, 32, 64, 128, 256MB x1 Total System Memory (Max 768MB) = Total Memory SPD Support This motherboard supports SPD DIMMs. 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 . This motherboard operates at 100MHz, thus most systems 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 for system stability. • Two possible memory chips are supported: SDRAM with and without ECC. • SDRAM chips are generally thinner with higher pin density than EDO (Extended Data Output) chips. • BIOS shows SDRAM memory on bootup screen. • 4 or 8 chips/side modules do not support ECC, only 5 or 9 chips/side modules support ECC. • Single-sided DIMMs come in 4, 8, 16, 32, 64,128MB; double-sided come in 8, 16, 32, 64, 128, 256MB. 18 ASUS P2V-B User's Manual
