1-3 Special Features
Advanced Communications Riser Card (ACR)
The ACR (Advanced Communications Riser Card), combining several
existing communications buses with new and advanced
communications buses, provides low-cost, high-performance
communications solutions to the industry. The ACR Specification
supports modem, audio, Local Area Network (LAN), and Digital
Subscriber Line (DSL). Pins are also reserved for future wireless bus
support. The ACR Specification enables riser-based broadband
communications, networking peripheral and audio subsystem designs.
ACR accomplishes this in an open-standards context.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the SUPER
370DDE motherboard.
Seven Onboard Voltage Monitors for the CPU Core, Chipset
Voltage, +3.3V,
± ±
± ± ±
5V and
± ±
± ± ±
12V
The onboard voltage monitor will scan these seven voltages continuously.
Once a voltage becomes unstable, it will give a warning or send an error
message to the screen. Users can adjust the voltage thresholds to define
the sensitivity of the voltage monitor.
Four-Fan Status Monitor with Firmware/Software On/Off Control
The PC health monitor can check the RPM status of the cooling fans. The
onboard 3-pin CPU and chassis fans are controlled by the power manage-
ment functions. The thermal fan is controlled by the overheat detection
logic.
Environmental Temperature Control
The thermal control sensor monitors the CPU temperature in real time and
will activate the thermal control fan whenever the CPU temperature ex-
ceeds a user-defined threshold. The overheat circuitry runs independently
from the CPU. It can continue to monitor for overheat conditions even when
the CPU is in sleep mode. Once it detects that the CPU temperature is too
high, it will automatically turn on the thermal control fan to prevent any
overheat damage to the CPU. The onboard chassis thermal circuitry can
monitor the overall system temperature and alert users when the chassis
temperature is too high.
