Memtestx86

Error explanation

Example of Memtest that has encountered errors. It shows which sector/address has failed.

The first column (Tst) shows which test has failed, the number corresponds to the test number from the list already mentioned above. The second column (Pass) shows if that test has passed. In the case of the example, test 7 has no passes.

The third column (Failing Address) shows exactly which part of the memory has errors. Such a part has an address, much like an IP address, which is unique for that piece of data storage. It shows which address failed and how big the data chunk is. (0.8MB in the example)

The fourth (Good) and fifth (Bad) columns show the data that was written and what was retrieved respectively. Both columns should be equal in non-faulty memory (obviously).

The sixth column (Err-Bits) shows the position of the exact bits that are failing.

Theseventh column (Count) shows the number of consecutive errors with the same address and failing bits.

Finally, the last, column seven (Chan) shows the channel (if multiple channels are used on the system) which the memory strip is in.
