CPU Thermal Monitor The Atlantis 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 waned 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 Atlantis motherboard automatically shuts down the computer if
the system voltage is 5% over the following standard voltage levels:
+12V,
+5V,
+3.3V, and
+2.8V.
SDRAM The Atlantis motherboard provides three 168-pin DIMM system memory
sockets that support up to 384 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.
The integrated I2C controller optimizes the memory timing parameters.
