3.3 System Memory Configuration

The FB81 mainboard has two 184-pin DIMM slots that allow you to install
from 128MB up to 2GB of system memory. Each 184-pin DIMM (Dual In-line
Memory Module) Slot can accommodate 128MB, 256MB, 512MB, 1GB and
2GB of PC2700/PC3200 compliant 2.6V single (1 Bank) or double (2 Bank)
side 64-bit wide data path DDR SDRAM modules.

Install Memory:

Install memory in any or all of the banks. The combination shown as follows.
Density
Device Width X8
Single Side 128MB 128MB 256MB 256MB 512MB
Double Side 256MB 256MB 512MB 512MB 1024MB
Note: 1. Maximum installed memory is 4GB.
2. Double -side X16 DDR-SDRAM chips are not supported.
3. Registered DIMM are not supported.
4. Only unbuffered without ECC DIMM are supported.
N o t e : 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
CMOS Setup

Upgrade Memory:

You can easily upgrade the system memory by inserting additional DDR SDRAM
modules in available DIMM slots. The total system memory is calculated by
simply adding up the memory in all DIMM slots. After upgrade, the new system
memory value will automatically be computed and displayed in the field "Stan-
dard CMOS Setup" of BIOS setup program.
