Question MemTestx86 not working

[BlazingAngels]

I have msi z370 pro carbon and corsair vengance 3000 mhz ram and I am trying to boot into memtest on flash drive but I keep on getting a message your pc needs to be repaired, under that it says your device you are trying to boot off of is ethier improperly configured or unreadable. Any advice to get this to work properly?

MemTestx86 is not anything that comes up in an internet search. Memtest86+ was a memory testing program that ceased being updated in 2013 after it developed problems using the UEFI type BIOS. Maybe that is what your using or there is a Passmark Memtest86.

MemTest86 is the original self booting memory testing software for x86 and ARM computers. Supporting both BIOS and UEFI, with options to boot from USB.
