System Memory (Dimm) - Asus P2E-N User Manual

III. INSTALLATION

2. System Memory (DIMM)

Only Dual Inline Memory Modules (DIMM) can be used with this motherboard.
Two sockets are available for 3.3Volt (power level) Unbuffered Synchronous DRAMs
(SDRAM) or EDO DRAM of either 8, 16, 32, 64, or 128MB. One side (with memory
chips) of the DIMM module 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 parity chip) and make
the proper settings in the BIOS Chipset Features Setup. (NOTE: ECC is only avail-
able on the P2L-N motherboard.)
IMPORTANT: Memory speed setup is required through "Auto Configuration" in
BIOS Chipset Setup of the BIOS SOFTWARE.
WARNING: Memory modules must have 18 chips or less. Memory modules
with more that 18 chips exceeds specifications and may cause unstable operation.
Install memory in any combination as follows:
DIMM Location
Socket 1 (Rows 0&1)
Socket 2 (Rows 2&3)
ASUS Memory Examples:
ECC EDO DIMM (9 chips)
Non-ECC SDRAM DIMM (8 chips)
General DIMM Notes: (not true for all memory modules)
• Four possible memory chips are available: EDO or SDRAM with and without ECC.
• 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 ECC, only 9 chip/side modules support ECC.
• Single sided modules are usually 16 or 64 MB, double sided are usually 8, 32, or 128MB.
