Introduction
SUPER i2DMR-8G2/i2DMR-iG2 User's Manual
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning
function in the BIOS. This allows the user to define an overheat tempera-
ture. When this temperature is exceeded, fans will speed up, and the
warning LED is triggered.
Auto-Switching Voltage Regulator for the CPU Core
The auto-switching voltage regulator for the CPU core can support up to
20A current and auto-sense voltage IDs ranging from 1.1V to 1.5V (*sup-
ported by VRMs only). This will allow the regulator to run cooler and thus
make the system more stable.
1-5 ACPI Features
External Modem Ring-On
Wake-up events can be triggered by a device such as the external modem
ringing when the system is in the SoftOff state. Note that external modem
ring-on can only be used with an SSI compliant power supply.
1-6 Power Supply
As with all computer products, a stable power source is necessary for
proper and reliable operation. It is even more important for processors that
have high CPU clock rates.
The SUPER i2DMR-8G2/i2DMR-iG2 requires a 24-pin connector and two 4-
pin 12V/15A connectors for CPU VRMs. Although most power supplies
generally meet the specifications required by the CPU, some are inadequate.
You should use one that will supply at least 500W of power, and an even
higher wattage power supply is recommended for high-load configurations.
Also your power supply must supply 2A for the Ethernet ports and the
E8870 chipset.
It is strongly recommended that you use a high quality power supply that
meets SSI EPS 12V 1U 500W PS Specification. To verify the status of SSI
compliance, please visit the web site at http://www.ssiforum.org/. Addi-
tionally, in areas where noisy power transmission is present, you may
choose to install a line filter to shield the computer from noise. It is recom-
