How to Resolve the MemTest86 Error on Test 10


Maintenance & Performance



What am I seeing?

When you run MemTest86 testing software, Intel® Server Boards and Intel® Server Systems may pass all tests but report failure on Test 10 [Bit fade test].

Instead of the expected 00000000 or FFFFFFFF, the address may contain a different hexadecimal value.

Some pages allocated with the AllocatePages() service may be above 4 GB if memory is present above 4 GB. The UEFI driver may dynamically overwrite the addresses reserved by MemTest86.

This behavior is normal and doesn't indicate any hardware failure.

How to fix it.

Entering BIOS setup and setting Boot Options > EFI Optimized Boot > Enabled allows the Bit fade test to pass.
