POST Error Beep Codes
The following table lists the POST error beep codes. Prior to system video initialization, the
BIOS uses these beep codes to inform users on error conditions. The beep code is followed by
a user-visible code on the POST Progress LEDs. For complete details, refer to the
BIOS for

Beeps Error Message POST Progress Code Description
1 USB device action NA Short beep sounded whenever a USB device is discovered
in POST, or inserted or removed during runtime
1 long Intel

0xAE, 0xAF System halted because Intel

Trusted Execution
Technology detected a potential violation of system
security.
3 Memory error See Table 45 and
Table 46 System halted because a fatal error related to the memory
was detected.
2 BIOS Recovery
started NA Recovery boot has been initiated
4 BIOS Recovery
failure NA BIOS recovery has failed. This typically happens so quickly
after recovery us initiated that it sounds like a 2-4 beep
code.
The Integrated BMC may generate beep codes upon detection of failure conditions. Beep codes
are sounded each time the problem is discovered, such as on each power-up attempt, but are
not sounded continuously. Codes that are common across all Intel server boards and systems
that use same generation chipset are listed in the following table. Each digit in the code is
represented by a sequence of beeps whose count is equal to the digit. For complete details,
refer to the

Code Reason for Beep Associated Sensors
1-5-2-1 No CPUs installed or first
CPU socket is empty. CPU1 socket is empty, or sockets are populated incorrectly.
CPU1 must be populated before CPU2.
1-5-2-4 MSID Mismatch MSID mismatch occurs if a processor is installed into a
system board that has incompatible power capabilities.
1-5-4-2 Power fault DC power unexpectedly lost (power good dropout) – Power
unit sensors report power unit failure offset.
1-5-4-4 Power control fault (power
good assertion timeout). Power good assertion timeout – Power unit sensors report
soft power control failure offset.
1-5-1-2 VR Watchdog Timer sensor
assertion VR controller DC power on sequence was not completed in
time.
1-5-1-4 Power Supply Status The system does not power on or unexpectedly powers off
and a Power Supply Unit (PSU) is present that is an
incompatible model with one or more other PSUs in the
system.
