Memory errors that exceed the error-correcting capabilities of ECC RAM.
x64 Exception Type 0x12 Machine Check Exception (MCE) , a critical hardware error indicating that the processor has detected a major internal or external bus error. On HPE ProLiant Gen10 servers, this often appears as a "Red Screen of Death" (RSOD) and is frequently linked to firmware bugs or PCIe communication timeouts.

To prevent this error from recurring:
: The processor has encountered an uncorrectable error, such as an internal machine error, a bus error, or a timeout from an external agent (like a PCIe card). Common Trigger (HPE Gen10)
The , more commonly known as a Machine Check Exception (MCE) , is a critical hardware error reported by the CPU when it detects an internal or external hardware inconsistency that it cannot resolve. Unlike software crashes, an MCE indicates that your physical hardware—or the low-level communication between components—has failed.

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.
This error is frequently reported on servers. In these environments, it often surfaces during the boot process or immediately following an OS installation. Troubleshooting and Fixes What is a Machine Check Exception
Help you interpret a specific iLO log if you can provide it. Direct you to HPE's support matrix to check compatibility.
In the x64 architecture, the CPU uses "Machine Check Architecture" (MCA) to monitor hardware health. When the processor encounters a "poisoned" bit of data, a voltage spike, or a parity error in its cache, it triggers . This immediately halts the system to prevent data corruption, often resulting in a Blue Screen of Death (BSOD) on Windows or a Kernel Panic on Linux. Common Causes of Exception 0x12 a voltage spike
