CPU Thermal Monitor The Olympus motherboard includes a special heat sensor under the CPU
that monitors the CPU temperature. This heat sensor generates an SMI (System
Management Interrupt) when the CPU temperature is too hot. The SMI can be
set to turn on the external cooling fan and/or lower the CPU clock frequency.
You are warned that the CPU is overheating. The CPU is returned to normal
operating conditions when the CPU temperature returns to normal. This feature
can only be implemented if a power supply with a soft-off power controller is
installed in the computer.
High Voltage Protection The Olympus motherboard automatically shuts down the computer if
the system voltage is 5% over the following standard voltage levels:
•
+12V, -12V,
•
+5V, -5V,
•
+3.3V, and
•
CPU core voltage.
SDRAM The Olympus motherboard provides four 168-pin DIMM system memory
sockets that support up to 512 MB of SDRAM (Synchronous Dynamic Random
Access Memory). SDRAM increases the CPU-to-memory data transfer rate to
528 MBs. The data transfer rate is 264 MBs if EDO DRAM is installed.
You can install 8 MB, 16 MB, 32 MB, 64 MB, or 128 MB SDRAM DIMM
modules.
