For end-users, the appearance of this error often means hardware replacement is necessary—usually memory, power supply, or the motherboard itself. For system administrators, implementing proactive monitoring for corrected errors, maintaining proper cooling and power protection, and using ECC memory on critical systems can prevent many MCEs from occurring in the first place.
A is a critical hardware-level error indicating that the processor has detected a severe, uncorrectable internal error. It is often displayed on a red screen during boot-up, commonly reported on high-end systems like HP ProLiant DL380 Gen10 servers.
Often triggered by a faulty processor, memory module (DIMM), or I/O device.
Excessive heat can cause thermal expansion issues or electronic migration that disrupts signal integrity.
A , often presented as a "Machine Check Exception," is a severe hardware-level error. This error typically occurs on high-performance servers (such as HPE ProLiant Gen10) or workstations, indicating that the processor has detected an internal, uncorrectable error, often related to the PCI Express bus or memory sub-systems.
Following common troubleshooting steps from the HPE Community , the admin checked the low-hanging fruit:

Help you interpret a specific iLO log if you can provide it. Direct you to HPE's support matrix to check compatibility.
The exception type 0x12 refers to a specific type of Machine Check Exception known as the Machine Check Exception Link. This exception allows for the linking of error records to provide more information about a hardware error that occurred.
