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

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.
Code Reason for Beep
1-5-2-1 No CPUs installed or first CPU socket is
empty.
1-5-2-4 MSID Mismatch
1-5-4-2 Power fault
1-5-4-4 Power control fault (power good assertion
timeout).
1-5-1-2 VR Watchdog Timer sensor assertion
1-5-1-4 Power Supply Status

Revision 1.1
Description
Short beep sounded whenever a USB device is discovered
in POST, or inserted or removed during runtime
System halted because Intel
Technology detected a potential violation of system
security.
System halted because a fatal error related to the memory
was detected.
Recovery boot has been initiated
BIOS recovery has failed. This typically happens so quickly
after recovery us initiated that it sounds like a 2-4 beep
code.
Associated Sensors
CPU1 socket is empty, or sockets are populated
incorrectly
CPU1 must be populated before CPU2.
MSID mismatch occurs if a processor is installed
into a system board that has incompatible power
capabilities.
DC power unexpectedly lost (power good dropout)
– Power unit sensors report power unit failure
offset
Power good assertion timeout – Power unit
sensors report soft power control failure offset
VR controller DC power on sequence was not
completed in time.
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.
