Important Notes
System Memory Combinations
The motherboard has two dual inline memory module (DIMM) sockets. Minimum memory size is 16 MB; maximum memory size is 256 MB. The BIOS automatically detects memory type, size, and speed.
The motherboard supports the following memory features: - 168-pin DIMMs with gold-plated contacts
- 66 MHz SDRAM only
- 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 | | 16 MB | 2M x 64 | 2M x 72 | | 32 MB | 4M x 64 | 4M x 72 | | 64 MB | 8M x 64 | 8M x 72 | | 128 MB | 16M x 64 | 16M x 72 |
Memory can be installed in one or two sockets. Memory size can vary between sockets.
Note: To function properly, SDRAM DIMMs must meet the Intel 4-clock, 66 MHz, unbuffered SDRAM specification for either 64-bit or 72-bit SDRAM. See the Technical Product Specification for information about these specifications.
DIMM Vendors - Web Sites
The list below contains vendors that have tested their memory for Intel® LM440LX Motherboards, and that have their products listed on their own website. Please visit their sites to obtain information on their products.

DIMM Vendors - SDRAM Non-ECC DIMMs
The following tables list DIMMs that have been tested. DIMMs that are not listed should also function properly as long as their specifications are compatible with the devices listed below. In general, DIMM devices that are faster than those specified for a given platform will work, although no extra performance will be realized.

DIMM Vendors - SDRAM ECC DIMMs
Error checking and correcting (ECC) memory detects multiple-bit errors and corrects single-bit errors. When ECC memory is installed, the BIOS supports both ECC and non-ECC mode. ECC mode is enabled in the Setup program. The BIOS automatically detects if ECC memory is installed and provides the Setup option for selecting ECC mode. If any non-ECC memory is installed, the Setup option for ECC mode does not appear.
The following table describes the effect of using Setup to put each memory type in each supported mode. Whenever ECC mode is selected in Setup, some performance loss occurs. Memory Error Detection Mode Established in Setup Program ECC Disabled ECC Enabled Non-ECC DIMM No error detection N/A ECC DIMM No error detection Single-bit error correction, multiple-bit error detection
