Bug check 0x12B: FAULTY_HARDWARE_CORRUPTED_PAGE
The FAULTY_HARDWARE_CORRUPTED_PAGE bug check has a value of 0x0000012B. This bug check indicates that the Windows memory manager detected corruption. That corruption could only have been caused by a component accessing memory using physical addressing.
This topic is for programmers. If you're a customer who has received a blue screen error code while using your computer, see Troubleshoot blue screen errors.
There are two scenarios where the memory manager raises FAULTY_HARDWARE_CORRUPTED_PAGE bug checks, with two different sets of parameters.
If parameters 3 and 4 are both zero, the bug check indicates that the memory manager detected a single-bit error on a page that the memory manager expected to be zeroed.
If parameters 3 and 4 are non-zero, the bug check is raised by the Compressed Store Manager due to a failure to decompress a page due to physical memory corruption.
Memory manager page not zero error parameters
This bug check indicates that a single-bit error was found in this page. This error is a hardware memory error.
|1||Virtual address maps to the corrupted page|
|2||Physical page number|
Compressed Store Manager error parameters
This bug check indicates that a store manager memory error has occurred. It might be an authentication failure, a CRC failure, or a decompression failure.
|1||FailStatus - Indicates the type of failure|
|2||The CompressedSize of the page that's being read|
This bug check can only occur by memory corruption due to physical memory access. The causes for physical memory corruption include:
- Defective RAM hardware.
- A driver or device incorrectly modifying physical pages via an incorrect DMA operation or associated MDL.
- Corruption caused by a hardware device or firmware corrupting memory, such as firmware illegally modifying physical pages across a power transition.
Compressed Store Manager can detect if the corruption was caused by a single-bit error and automatically corrects this condition without raising a bug check. This bug check is reported by the Compressed Store Manager if the corruption wasn't caused by a single bit error.
For more information on Windows memory manager and memory compression, see Windows Internals 7th Edition Part 1.
To investigate if this bug check is caused by defective RAM hardware, run the Windows Memory Diagnostics tool. In the control panel search box, enter Memory, and then select Diagnose your computer's memory problems. After the test is run, use the Event Viewer to view the results under the system log. Select the MemoryDiagnostics-Results entry to view the results.
