Dear PASSMARK

This is Portwell, Inc ERD Hanson
When we used MemTest86 7.5 Free, our project had error in Test13.
When we used MemTest86 8.4 Pro, this error would not happen .
We want to know the difference between ver7.5 Free and ver8.4 Pro


BR,
Hanson

You can find a list of changes here

There wasn't large changes in Test 13 between these releases. But memory ranges less than 1MB are no longer reserved for Bit fade test/Hammer test due to possible memory conflict issues.
But it is unlikely this is the cause of the change of behaviour. Are you sure it wasn't just an intermittent issue and the result is somewhat random.
