It is strongly recommended that you use 32-bit memory approved by your machine manufacturer. Using 16-bit memory instead will degrade overall machine performance.
If you see one of the following messages:
FATAL: parity error on the Motherboardsome part of your hardware is sending a ``non-maskable interrupt'' (a signal sent by the hardware that halts the operating system). The precise message will depend on your particular system. You should run your system's hardware diagnostics tests, if available. In addition, physically reseat your memory cards, SIMMs, or individual memory chips, checking for bent pins. If these measures fail to correct the problem (or you do not feel comfortable in checking your hardware yourself), seek professional hardware support.
