1.2 Processor and Chipset Overview

Built upon the functionality and capability of the AMD EPYC
SP5 sockets. The H13DSG-O-CPU motherboard offers maximum I/O expendability, energy
efficiency, and data reliability in a 5-nm process architecture, and is optimized for embedded
storage solutions, networking applications, or cloud-computing platforms.
With support of the new microarchitecture 5nm process technology, the H13DSG-O-CPU
drastically increases system performance for a multitude of server applications.
The AMD EPYC 9004 series processors support the following features:
TM
•
ACPI Power Management Logic Support Rev. 6.4
•
Adaptive Thermal Management/Monitoring
•
PCIe 5.0 w/transfer rate of up to 32.0 GT/s and SATA 3.0 w/ transfer rate of up to 6.0 GB/s
•
System Management Bus (SMBus) Specification Version 3.5 or later

1.3 Special Features

This section describes the health monitoring features of the H13DSG-O-CPU motherboard.
The motherboard has an onboard System Hardware Monitor chip that supports system health
monitoring.

Recovery from AC Power Loss

The Basic I/O System (BIOS) provides a setting that determines 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 press the power switch to turn it back on), or
for it to automatically return to the power-on state. See the Advanced BIOS Setup section
for this setting. The default setting is Last State.
