ASUS L1N64-SLI WS/B 2-
2.4 System memory
2.4.1 Overview
The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory
Modules (DIMM) sockets.
A DDR2 module has the same physical dimensions as a DDR DIMM but has a
240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched
differently to prevent installation on a DDR DIMM socket.
The figure illustrates the location of the DDR2 DIMM sockets:
Channel Sockets
Channel 1 DIMM_A1 and DIMM_B1
Channel 2 DIMM_A2 and DIMM_B2
• When using only one CPU, install memory modules to DIMM_A1 and
DIMM_B1 slots only.
• Always use memory modules with same memory size and frequency.
• For dual-channel memory configuration, the DDR2 DIMMs can be installed
in DIMM_A1 and DIMM_A2 either in one CPU mode or dual CPU mode.
