CPU Installation
CPU Installation Notes
Please visit ASRock website and refer to user manual pages 14 to 23.
CPU Fan Connector
1. Please connect the CPU fan or radiator fan to the header “CPU_FAN1”. This way,
the CPU temperature will be used as reference for the CPU fan.
(If for some reason you would like to use a different header for the CPU/radiator
fan, make sure to select “Monitor CPU” as “Temp Source” for that header.)
2. If an AIO water cooler is used, please connect the pump to CPU_FAN2/WP, as it is
set to W_PUMP mode and full speed by default.

(incompatible slots).
2. Debug code "00" is shown during AMD AGESA initialization. This code can be seen
for a relatively long period during the first boot, and it is does not mean that the
system has crashed or frozen.
*The boot time provided is for reference only. The actual boot time may vary depending on
the system configuration.

Other important topics
1. AMD Overclocking Notification and Registration.
When you attempt to overclock the system, the BIOS will display an AMD
overclocking notification. This notification is part of AMD's overclocking
mechanism. Press “yes” if you want to enter overclocking mode. This will be
registered within the AMD CPU, for reference by the AMD warranty team.
A CPU will generate this warning message only once. After accepting the message
and consequences, the BIOS will no longer display this message with this CPU.

2. Connecting a Secondary PSU
A secondary PSU is not mandatory but can be used. It can be connected to the 3-
pin ATX Power Connector ATX_CON1, using a Multi PSU Adaptor Cable. All the
power cables from the secondary PSU will be available for connecting to the
motherboard.
The Multi PSU Adaptor Cable will come with the TRX50 WS package.

3. Flashback Feature
TRX50 WS supports the flashback feature. It allows you to update the BIOS
without powering on the system, and even without CPU. The flashback button and
the corresponding USB port are on the Rear IO panel, as shown below.
The flashback update procedure can be found on the ASRock website and
user manual page 56.
