How to Install Memory
You can install from 8 MB to 384 MB of memory in the motherboard DIMM sockets. The board
has DIMM sockets arranged as banks 0, 1, and 2. The motherboard supports the following
memory features:
• 168-pin DIMMs with gold-plated contacts
• 66 or 100 MHz SDRAM
• Non-ECC (64-bit) and ECC (72-bit) memory
• 3.3 V memory only
• Single- or double-sided DIMMs in the following sizes:
DIMM Size Non-ECC Configuration ECC Configuration
8 MB 1 Mbit x 64 1 Mbit x 72
16 MB 2 Mbit x 64 2 Mbit x 72
32 MB 4 Mbit x 64 4 Mbit x 72
64 MB 8 Mbit x 64 8 Mbit x 72
128 MB 16 Mbit x 64 16 Mbit x 72
When adding memory, follow these guidelines:
• You can install DIMMs in any of the three banks.
• You can use different sizes of DIMMs in different banks.
• The BIOS detects the size and type 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).
✏NOTE
All memory components and DIMMs used with the SE440BX motherboard must comply with the
PC SDRAM specifications. These include: the PC SDRAM Specification (memory component
specific), the PC Unbuffered DIMM Specification, and the PC Serial Presence Detect
Specification. You can access these documents through the Internet at:
