Introduction
Each Intel 5520 supports up to 36 PCI Express Gen2 lanes with peer-to-peer read and write
transactions. The ICH10R provides up six SATA ports and 10 USB connections.
In addition, the SB5520DT1 chipset also offers a wide range of RAS (Reliability, Availability and
Serviceability) features. These features include memory interface ECC, x4/x8 Single Device Data
Correction (SDDC), Cyclic Redundancy Check (CRC), parity protection, out-of-band register
access through SMBus, memory mirroring, memory sparing, and Hot-plug support on the PCI-
Express Interface.

Special features

Recovery from AC power loss

The BIOS provides a setting for you to determine how the system will respond when AC power
is lost and then restored to the system. You can choose for the system to remain powered off
(in which case you must hit the power switch to turn it back on) or for the system to
automatically return to a power- on state. See the
setting. The default setting is Last State.

PC health monitoring

This section describes the PC health monitoring features of the SB5520DT1. All have an
onboard System Hardware Monitor chip that supports PC health monitoring. An onboard voltage
monitor continuously scans these onboard voltages: CPU1 Vcore, CPU2 Vcore, CPU1 Vtt, CPU2
Vtt, CPU1 DIMM, CPU2 DIMM, 1.1V, 1.5V, 1.8V, 3.3V, 12V, 5V, 3.3 Vsb, and VBAT. Once a
voltage becomes unstable, a warning is given or an error message is sent to the screen. The
user can adjust the voltage thresholds to define the sensitivity of the voltage monitor.

Fan status monitor with firmware control

The PC health monitor can check the RPM status of the cooling fans. The onboard CPU and
chassis fans are controlled by the BIOS Thermal Management (refer to
