3.3 System Memory Configuration
The AB48/AB48N mainboard has two 184-pin DIMM banks that allow you
to install from 128MB up to 1GB of system memory.
Each 184-pin

184-pin DIMM (Dual In-line Memory Module) bank can accommo-
date 128MB, 256MB, 512MB, and 1GB of PC2100/PC2700 compliant 2.5V
single or double side unbuffered with or without ECC Registed DDR SDRAM
modules. DIMM slots are arranged in two banks, each memory bank made of
one bank and providing a 64-bit wide data path.
1. Install Memory:
Install memory in any or all of the banks. The combination shown as follows.
Maximum installed memory is 2GB.

Note: You do not need to set any jumper to configure memory since the
BIOS utility can detect the system memory automatically. You can
check the total system memory value in the BIOS Standard CMOS
Setup menu.
2. Upgrade Memory:
You can easily upgrade the system memory by inserting additional DDR
SDRAM modules in available DIMM banks. The total system memory is
calculated by simply adding up the memory in all DIMM banks After up-
grade, the new system memory value will automatically be computed and
displayed in the field "Standard CMOS Setup" of BIOS setup program.
