Upgrading DRAM Memory
You can upgrade the system memory by replacing the factory-installed SIMMs with
higher-capacity SIMMs.
Caution
Since the SIMMs sockets on your motherboard are tin-plated, use only tin-
plated SIMMs when upgrading your system memory. If you use gold-
plated SIMMs, your system may become unstable.
To plan your SIMM configuration, refer to Table 1–1. Contact your Unisys Sales
Representative for the availability of SIMMs.
Note: If a 36-bit SIMM is installed, use the “ECC/Parity Config” setting in the
BIOS to enable ECC/Parity support.
