WHEA_UNCORRECTABLE_ERROR
Fatal WHEA hardware error
WHEA_UNCORRECTABLE_ERROR is bug check code 0x00000124. The built-in table identifies it as WHEA_UNCORRECTABLE_ERROR
; the useful diagnostic question is what Windows component raised the stop and which invariant failed.
This bug check uses the Windows Hardware Error Architecture error record. The source can be machine check, PCI Express, NMI, platform firmware, persistent memory, driver-reported hardware error source, or another WHEA source.
How to read the parameters
- Parameter 1 identifies the type of WHEA error source.
- Parameter 2 is the address of the WHEA_ERROR_RECORD structure.
- For machine checks, parameters 3 and 4 can contain high and low parts of the MCi_STATUS value.
What to check in the dump
- Use !errrec on the WHEA_ERROR_RECORD address when available.
- Correlate with System log WHEA events, firmware logs, thermals, memory tests, PCIe AER data, and CPU/memory overclocking.
- Do not reduce it to one cause; the WHEA source type and error record decide whether CPU, memory, PCIe, firmware, or a device driver source is involved.
