System Memory Combinations
The TC430HX provides four 72-pin SIMM sockets that make it possible to install up to 128 MB of RAM. The sockets support 1M x 32 (4 MB), 2M x 32 (8 MB), 4M x 32 (16 MB), and 8M x 32 (32 MB) single- or double-sided modules. Minimum memory size is 8 MB and maximum memory size, using four 8M x 32 SIMM modules, is 128 MB. Memory timing requires 70 ns fast page devices or, for optimum performance, 60 ns EDO DRAM. If the maximum external microprocessor clock speed is 60 MHz or slower, 70 ns EDO DRAM may be used. Parity, ECC, and non-parity memory are all supported.
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 different types of memory may differ between banks.
The TC430HX 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
Bank 0 (SIMM 1, 2) Bank 1 (SIMM 3, 4) Total System Memory 1M x 32 Empty 8 MB Empty 2M x 36 16 MB 1M x 32 4M x 32 40 MB
It is even possible to have 70 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.

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.

Tested 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 (e.g., for the 100, 133, and 166 MHz Pentium processor). 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.
