errors in v4 but not in v6?? what is this

[rayuki]

so im having some weird BSODs with my PC at the moment coming up with Memory_Management so i thought i'd double check my ram was fine first before looking at other stuff. i ran memtest and it at first loaded up in usb mode so loaded up the old v4. i got something like 500+ errors over the run.

ran it about 3 more times to check and all the time tons of errors with v4. decided to load up v6 in UEFI and it just finished without a single error.

any idea what the hell is going on here?

Could be a BIOS bug causing MemTest86 v4 to test system address ranges not belonging to physical RAM.

Can you post a screenshot of the errors.
