System Memory Installation
You can install from 16 MB to 768 MB of memory in the motherboard DIMM sockets.
The board has DIMM sockets arranged as banks 0, I, and 2. The motherboard supports
the following memory features:
• 168-pin SDRAM DIMMs.
• 100 MHz or 66 MHz unbuffered SDRAM DIMMs.
• Non-ECC (64-bit) or ECC (72-bit) memory.
• 16 MB, 32 MB, 64 MB, 128 and 256 MB modules.
When adding memory, follow these guidelines:
• You can install DIMMs in any of the three banks.
• You can use different size DIMMs in different banks.
• The BIOS detects the size of installed memory.
• For ECC operation to be available, all installed memory must be ECC and you must
enable the ECC Configuration feature in the Setup program (see chapter 3).
The motherboard layout at the beginning of this manual shows the location of the DIMM
sockets. To install DIMMs, follow these steps:
1. Turn off all peripheral devices connected to the computer. Turn off the computer.
2. Remove the computer cover and locate the DIMM sockets.
3. Holding the DIMM by the edges, remove it from its anti-static package.
4. Make sure the clips at either end of the socket are pushed away from the socket.
5. Position the DIMM above the socket. Align the two small notches in the bottom edge
of the DIMM with the keys in the socket.
6. Insert the bottom edge of the DIMM into the socket.
7. When the DIMM is seated, push down on the top edge of the DIMM until the
retaining clips at the ends of the socket snap into place. Make sure the clips are firmly
in place.
