3.5 System Memory (DIMM)
This motherboard uses only Dual Inline Memory Modules (DIMMs). Three sockets
are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random
Access Memory (SDRAM) of 8, 16, 32, 64, 128, 256, 512 or 1024MB to form a
memory size between 8MB to 3GB. One side (with memory chips) of the DIMM
takes up one row on the motherboard.
Memory speed setup is recommended through SDRAM Configuration under “Chipset
Features Setup”.
IMPORTANT (see General DIMM Notes below for more):
•
SDRAMs used must be compatible with the current Intel PC133
SDRAM specification.
•
DO NOT attempt to replace PC133 SDRAMs with VCM SDRAMs.
•
The motherboard only supports PC100 / PC133 unbuffered DIMM
SDRAMs for system memory. Registered DIMMs are not supported.
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, 256, 512, 1024MB x1
Socket 2 (Rows 2&3)
SDRAM 8, 16, 32, 64, 128, 256, 512, 1024 MB x1
Socket 3 (Rows 4&5)
SDRAM 8, 16, 32, 64, 128, 256, 512, 1024 MB x1
Total System Memory (Max 3GB) =
3.5.1 General DIMM Notes
•
DIMMs that have more than 18 chips are not supported on this motherboard.
•
For the system CPU bus to operate at
100
MHz/133MHz, use only PC100-/PC133-
compliant DIMMs.
•
ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the
memory of choice for best performance vs. stability.
•
BIOS shows SDRAM memory on bootup screen.
•
Single-sided DIMMs come in 16, 32, 64,128, 256, 512MB; double-sided DIMMs
come in 32, 64, 128, 256, 512 and 1024MB.
WARNING!
Be sure that the DIMM you use can handle the specified SDRAM
MHz or else bootup will not be possible.
