EVGA X299 Micro (131-SX-E295)
POST Beep codes
POST beeps are used in conjunction with the POST Code indicator to help determine
the root cause of the issue when your system is malfunctioning. However, with the
advent of modern UEFI/BIOS, the USB detection can throw off the number of beeps
making the POST code, while helpful, not as useful as it once was. The motherboard
will typically beep 1-2 times per USB device plugged in at boot; some will beep more
based on functions of the device. These may occur at the same time as the system's
POST beeps, so it can
sometimes be a challenge to
separate the POST beeps from
the USB initialization. Since the
POST code indicator now fills
most of the role previously held
by audible beeps, there are far
fewer POST beeps to help
debug problems, compared to
previous motherboard
generations.
1 Beep: This relates to BIOS boot passwords. The BIOS will beep, indicating that a
password is required to boot. If you incorrectly enter your BIOS password when
prompted by the BIOS, you will receive one beep.
4 Beeps: This is an error relating to some small recovery errors, which can occur when
coming out of sleep/hibernate.
5 Beeps: This error is stating it cannot detect a keyboard. This can also indicate a video
card is not detected.
6 Beeps: This relates to either a failed BIOS update, or a failed Intel ME Firmware
update.
7 Beeps: This relates to a failed CPU INIT request. EFI/UEFI Reset protocol is used
when a processor INIT call is used and was not successful. This returns either an
"EFI_UNSUPPORTED" error if the INIT type is not supported or an
"EFI_Device_Error" if the error occurs while generating the INIT; either will result in
seven (7) POST beeps.
8 Beeps: Error given when an incompatible PCI Express device is installed and cannot
initialize properly.
