3.3 System Memory Configuration

The FB75 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 accommodate 64MB, 128MB, 256MB, 512MB,
and 1GB of PC2700 or PC3200 compliant 2.5V single (1 Bank) or double (2
Bank) side 64-bit wide data path DDR SDRAM modules. You need not 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.

Install Memory:

Install memory in any or all of the slots. The combination is shown as follows.

Note: Maximum installed memory is 2GB.
DIMMs population:
1. 128 Bit Mode: Exactly the same size and type DIMMs on Channels 0/1.
2. 2*64 Bit Mode: DIMMs installed on different Channels.

Upgrade Memory:

You can easily upgrade the system memory by inserting additional DDR
SDRAM modules in available DIMM slots. The total system memory is calcu-
lated 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 "Standard CMOS Setup" of BIOS setup program.
