Removing and installing memory modules

The four DIMM sockets on board accept 64-, 72-, 128-, 144-, 256-, and 512-MB SDRAM (synchronous DRAM) DIMMs for a maximum memory upgrade capacity of up to 4 GB.

For the system to function properly, you have to install at least two DIMMs of 1.3 or 2.4 ___. Install it in either DIMM slot ____ or _______.

The SDRAM DIMMs should work under 3.3 volts only; 5-volt memory devices are not supported. The mainboard supports both 200 and 266 MHz SDRAM DIMMs (PC-1600 and PC-1200). Contact your dealer for qualified DIMM vendors.

This mainboard supports 100 and 133 MHz SDRAM. However, they cannot be used at the same time in the system.

Warning! Do not use both 100 MHz and 133 MHz SDRAM together. This might cause your system to malfunction.

Each of the DIMM sockets is independent from the others. This independence allows you to install DIMMs with different capacities to form different configurations.

Removing a DIMM

Before you can install a new DIMM in a socket, remove first any previously installed DIMM from that socket.

1Remove the system cover. See page 37 for more detailed instructions.

2Locate the DIMM socket on the mainboard.
