System Memory Combinations
The Intel® VS440FX Motherboard provides four 72-pin SIMM sockets that make it possible to install up to 256 MB of RAM. The sockets support 1M x 32/36 (4 MB), 2M x 32/36 (8 MB), 4M x 32/36 (16 MB), 8M x 32/36 (32 MB), and 16M x 32/36 (64 MB) single or double-sided, parity (x36), non-parity (x32), or ECC modules. Minimum memory size is 8 MB and maximum memory size, using four 16M x 32/36 SIMM modules, is 256 MB. Memory timing requires 60 ns fast page devices or, for optimum performance, 60 ns EDO DRAM.

The four sockets are arranged in two banks of two sockets each. The sockets are designated Bank 0 and Bank 1. Each bank provides a 64/72-bit wide data path. Both SIMMs in a bank must be of the same memory size and type, although the types of memory may differ between banks. The following tables show the possible memory combinations and an example of memory installation.

The Intel® VS440FX Motherboard supports only tin-lead SIMMs.

  Bank 0 (SIMM 1, 2) Bank 1 (SIMM 3, 4) Total System Memory Populated Empty Varies with SIMM size Empty Populated Varies with SIMM size Populated Populated Varies with SIMM size

• SIMM Memory Example

  Bank 0 (SIMM 1, 2) Bank 1 (SIMM 3, 4) Total System Memory 1M x 32 Empty 8 MB Empty 4M x 36 32 MB 2M x 32 8M x 32 80 MB

It is even possible to have 60 ns Fast Page DRAM in one bank and 60 ns EDO DRAM in the other. In that case, each bank is independently optimized for maximum performance. Bank 0 only, Bank 1 only, or both of the banks may be populated. There are no jumper settings required for the memory size or type, that is automatically detected by the system BIOS.

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

All Sizes: Tin-lead contacts

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

Note: 60ns EDO SIMMs are required when the external CPU clock is set to 66 MHz. Either 60ns or 70ns SIMMs can be used for external clock frequencies of 50 MHz and 60 MHz, but no additional performance will be seen with the 60ns SIMMs.

All Sizes: Tin-lead contacts

SIMM Vendors - EDO ECC SIMMs

In general, SIMM devices that are faster than those specified for a given platform will work, although no extra performance will be realized.

Note: 60ns EDO SIMMs are required when the external CPU clock is set to 66 MHz. Either 60ns or 70ns SIMMs can be used for external clock frequencies of 50 MHz and 60 MHz, but no additional performance will be seen with the 60ns SIMMs.
