The FAULTY_HARDWARE_CORRUPTED_PAGE bug check has a value of 0x0000012B. This bug check indicates that the Windows memory manager detected corruption, and the corruption could only have been caused by a component accessing memory using physical addressing.


This topic is for programmers. If you are 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 will raise 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 Memory Manager detected a single-bit error on a page that was 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 is a hardware memory error.

Parameter Description


Virtual address maps to the corrupted page


Physical page number





Compressed Store Manager Error Parameters

This bug check indicates that a store manager memory error has occurred. It may be an authentication failure, a CRC failure, or a decompression failure.

Parameter Description


FailStatus - Indicates the type of failure


The CompressedSize of the page that is being read


Source Buffer


Target Buffer


This bugcheck can only occur by memory corruption due to physical memory access. The causes for physical memory corruption include:

  1. Defective RAM hardware
  2. A driver or device incorrectly modifying physical pages via an incorrect DMA operation or associated MDL.
  3. Corruption caused by a hardware device or firmware corrupting memory, such as firmware illegally modifying physical pages across a power transition.

NOTE: 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 bugcheck is reported by the Compressed Store Manager if the corruption was not caused by a single bit error.

Windows Memory Diagnostics Tool

To investigate if this bug check is caused by defective RAM hardware, run the Windows Memory Diagnostics tool. In the control panel search box, type Memory, and then click Diagnose your computer's memory problems.‌ After the test is run, use Event viewer to view the results under the System log. Look for the MemoryDiagnostics-Results entry to view the results.
