Inline Memory Modules (SIMMs)
Equium™ Models 5120D, 5200D, and 6200D computers come equipped with 32 MB of
RAM.
Models 5160D and 5200D SIMM Configuration
The system board in Equium Models 5160D and 5200D, the Intel CU430HX, has six 72-pin,
tin lead SIMM sockets, arranged as three banks, each with two sockets. Some important
considerations are:
• The board supports 60 ns Extended Data Out (EDO) SIMMs.
• The board supports non-parity SIMMs only.
• Both sockets of a bank must be used.
• Both sockets of a bank must contain the same type (EDO), speed (60 ns), and size of
SIMM.
• Only tin lead 72-pin SIMMs can be used with the standard tin lead SIMM sockets.
• There are no jumper settings required for the memory size or type. This information
is automatically detected by the system BIOS.
The sockets support the following SIMM sizes:
Model 6200D SIMM Configuration
The system board in the Equium Model 6200D, the Intel AP440FX, has four 72-pin tin-lead
SIMM sockets that make it possible to install up to 128 MB of RAM. The sockets support
1M x 32 (4 MB) single-sided modules, 2M x 32 (8 MB), 4M x 32 (16 MB), and 8M x 32 (32
MB) single-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 60 ns fast page devices
or, for optimum performance, 60 ns EDO DRAM. Both parity and non-parity memory
modules are supported. With parity SIMMs, the board can be configured to support ECC
operation.
