3.3 System Memory Configuration

The FN41U mainboard has two 184-pin DIMM slots that allow you to install
from 64MB up to 2GB of system memory. Each 184-pin DIMM (Dual In-line
Memory Module) slot can accommdate 64MB, 128MB, 256MB, 512MB,
and 1GB of PC1600/PC2100/PC2700/PC3200 compliant 2.5V single or
double side 64-bit wide data path DDR SDRAM modules. 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.

1. Install Memory:

Install memory in any or all of the banks. The combination shown as follows.
Density
Device Width x8
Single/Double SS/DS
184 pin DDR 64/
DMMMs 128MB
Note: The total installed memory does not exceed 2GB.
Note: Installing a DIMM in any slot leads to a 64-bit data transfer
rate. To activize a dual-channel feature of a 128-bit data
transfer rate, install DIMMs in both slots.

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.
