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 Ac-
cess 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.
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 (Ex-
tended 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.
Install memory in any combination as follows:
DIMM Location 168-pin DIMM Memory Modules Total Memory
Socket 1 (Rows 0&1) SDRAM 4, 8, 16, 32, 64, 128, 256MB x1
Socket 2 (Rows 2&3) SDRAM 4, 8, 16, 32, 64, 128, 256MB x1
Socket 3 (Rows 4&5) SDRAM 4, 8, 16, 32, 64, 128, 256MB x1
Total System Memory (Max 768MB) =

SPD Support
This motherboard supports SPD DIMMs. It is recommended that SPD DIMMS be
used.
