Pc-Check Windows Memory Chequerboard Test Failure Information

Group Number 100X

Device Memory

This is a group that tests physical memory.

100% of the memory cannot be tested due to certain hardware devices and drivers that load in the Windows® environment. The memory between 641K and 1024K is not tested, as this is where BIOS and other system resources reside. The reported amount of tested memory may vary from one test to another due to background activity of the operating system. Once any test is executed the system maybe slow to respond as the Windows® OS has been reduced to a minimum amount of memory. Any subsequent tests maybe slow to respond whilst windows recovers the memory therefore it is recommended this test is executed last.

If you are executing 32 bit Windows® diagnostics the maximum amount of tested memory is 2GB. It is recommended all external programs are closed whilst executing this test. Any interface running the test will slow down dramatically in response.

Note: If the user tries to stop the running of a memory test or the entire group of tests when the system is busy, there may be a delay in the response.

Note: The Pseudo-random seed is shown twice in the table with the maximum value depending on platform. Only one will be valid and used.

Note: If testing with a duration, for all tests this should be greater than 59 seconds.

Test number 307

Test Name Chequerboard

Writes pattern 0xA into memory and verifies that it was stored correctly. Then writes pattern 0x5 and verifies that this pattern was also stored correctly.

PARAM1: Duration

Time to run the test. (in seconds) The minimum value for this parameter is 60 unless a test on coverage is desired. In this case, 0 should be used.

PARAM2: Coverage

Percentage of maximum testable memory to test.

PARAM5:Memory Allocation

Percentage of memory allocated from available Physical memory to be used for the test.

ERRORCODES & TROUBLESHOOTING

Mismatch of memory. CODE="0x00/3FF"

TROUBLESHOOTING_ID:0: The data written and read did not match or information was unable to be read from the memory. The memory appears to be faulty.

Unknown communication failure. CODE="0x01/001"

TROUBLESHOOTING_ID:2: This error is either caused by the memory or is a Windows® Related Error. Retest with operating system group.

Memory failed integrity check. CODE="0x02/3FF"

TROUBLESHOOTING_ID:0: The data written and read did not match or information was unable to be read from the memory. The memory appears to be faulty.

Memory writing error during test. CODE="0x04/004"

TROUBLESHOOTING_ID:0: The data written and read did not match or information was unable to be read from the memory. The memory appears to be faulty.

Error attempting to obtain or free memory to test. CODE="0x07/001"

TROUBLESHOOTING_ID:0: The data written and read did not match or information was unable to be read from the memory. The memory appears to be faulty.

Duration parameter invalid. CODE="0x08/3FF"

TROUBLESHOOTING_ID:1: Parameter error associated with duration. Duration should be at least 60 seconds.

Failure to create process to execute memory tests. CODE="0x09/001"

TROUBLESHOOTING_ID:2: This error is either caused by the memory or is a Windows® Related Error. Retest with operating system group.

Unknown memory result. CODE="0x0A/3FF"

TROUBLESHOOTING_ID:2: This error is either caused by the memory or is a Windows® Related Error. Retest with operating system group.

Internal error. CODE="0x0B/3FF"

TROUBLESHOOTING_ID:2: This error is either caused by the memory or is a Windows® Related Error. Retest with operating system group.

General Windows® Exception during memory tests. CODE="0x11/008"

TROUBLESHOOTING_ID:0: The data written and read did not match or information was unable to be read from the memory. The memory appears to be faulty.

Unable to gather all required information about system memory. CODE="0x12/3FF"

TROUBLESHOOTING_ID:2: This error is either caused by the memory or is a Windows® Related Error. Retest with operating system group.

Failed to read diagnostic records from event log. CODE="0x13/3FF"

TROUBLESHOOTING_ID:0: The data written and read did not match or information was unable to be read from the memory. The memory appears to be faulty.

TROUBLESHOOTING_ID:3: Windows Memory Diagnostics may not have been run. To launch the Windows Memory Diagnostic tool, open the Start menu, type Windows Memory Diagnostic, and press Enter.
