which can be extended into two USB 3.2 Gen 1 Type-A interfaces
and is backward compatible with USB 2.0 devices.
8
Front audio pin (F_AUDIO)
The audio interface on the front panel of the chassis can be
connected to the front audio pin through the audio cable inside the
chassis, allowing you to implement audio input/output and other
functions through the audio interface on the front panel.
9
BIOS burner pin (JBIOS)
The BIOS burner pin can be used to upgrade the mainboard
BIOS by connecting the BIOS burner when the regular BIOS
upgrade is not possible.
10
Serial port pin (COM)
The serial port pin can be used to connect the serial port module.
First connect the data cable of the serial port module to the serial
port pin, and then fix the module in the empty slot on the rear panel
of the chassis to connect the serial port device.
11
Front USB 2.0 pin (FUSB2.0_1, FUSB2.0_2)
This mainboard provides two front USB 2.0 extended pins, which
can be extended into four USB 2.0 interfaces.
12
Diagnostic card pin (ESPI_HEADER)
The diagnostic card pin can be used to connect the mainboard
diagnostic card and analyze the cause of the mainboard failure
based on the code displayed on the diagnostic card.
13
Speaker pin (SPEAK)
The speaker pin can be used to connect the speaker on the
chassis.

CPU Base
When installing the CPU, please make sure your CPU uses the AM5 slot;
Align the two alignment points and a gold triangle indicator on the edge of the
CPU and mainboard and insert them for installation.
Notice
· When changing the processor, due to the architecture of the AM5 processor, the
system configuration can be cleared and the BIOS is reset to the default values.
· Before installing or removing the CPU, please turn off the power and unplug the
power cord from the socket.
· Please keep the CPU protective cover after installing the processor. Sapphire®
requires a protective cover on the CPU base attached to the mainboard when it is
returned to After-sales Services.
· When installing the CPU, please make sure that the CPU radiator is installed and
the thermal grease (or phase change film) is applied correctly. The CPU radiator is
necessary to prevent overheating and maintain system stability.
· Excessive temperature can seriously damage the CPU and system. Please make
sure that the CPU cooling system used can always work properly to protect the
CPU from overheating and burning.
· If the CPU is not installed, please cover the CPU base protective cover on the
CPU base to avoid damage to the base.

Memory Module Installation
Notice
· The DIMM slot of this mainboard only has single-sided ear clip. Be careful when installing
or removing the memory module to avoid damage to the slot. · To ensure system stability
in dual-channel mode, memory modules must be of the same type, quantity and density.
· When the memory is overclocked, the stability and compatibility of the memory module
depends on the installed CPU and device.
