System Memory (Dimm) - Asus SP98AGP-X User Manual

III. INSTALLATION

2. System Memory (DIMM)

Only Dual Inline Memory Modules (DIMMs) can be used with this motherboard.
Three sockets are available for 3.3Volt (power level) Unbuffered Synchronous
DRAMs (SDRAMs; 8, 16, 32, 64, or 128MB) or EDO DRAM (8, 16, 32, 64, 128, or
256MB) to form a memory size between 8MB to 768MB. One side (with memory
chips) of the DIMM module takes up one Row on the motherboard. If ECC-sup-
ported DIMM is used, you can enable the ECC function through BIOS setup –
CHIPSET FEATURES SETUP "Data Integrity Mode."
IMPORTANT: You must first set the memory speed through the "EDO/FPM Con-
figuration" under the BIOS Chipset Setup of the BIOS SOFTWARE.
Install memory in any combination as follows:
DIMM Type
Socket 1 SDRAM 8, 16, 32, 64, 128MB
(Rows 0&1) EDO
Socket 2 SDRAM 8, 16, 32, 64, 128MB
(Rows 2&3) EDO
Socket 3 SDRAM 8, 16, 32, 64, 128MB
(Rows 4&5) EDO
Total System Memory (Max 768MB)
WARNING: Memory modules must have 18 chips or less. Memory modules with
more that 18 chips will cause unstable operation.
ASUS DIMM Module Examples:
ECC EDO DIMM (9 chips)
General DIMM Notes: (not true for all memory modules)
• Four possible memory chips are supported: EDO or SDRAM with and without parity.
• SDRAM chips are generally thinner with higher pin density than EDO chips.
• BIOS shows EDO or SDRAM memory on bootup screen.
• 8 chip/side modules do not support parity, only 9 chip/side modules support parity.
• Single sided modules are usually 16 or 64 MB, double sided are usually 8, 32, or 128MB.
