In cases of deviced with soldered/integrated RAM (eg tablets and ultrabooks), a defect in the memory means that the computer becomes an expensive paperweight.
It is clear that the best alternative is to replace the defective RAM, but when this is not possible, and the equipment no longer under warranty, is a good time to try other solutions.
I have been researching
bcdedit /set badmemorylist and
bcdedit /set badmemoryaccess without success.
This question discussed the issue a few years ago: Running Windows with defective RAM
At that time and in those cases, there was a possibility to replace the RAM, and no more was investigated.
Now I have no possibility of replacing the RAM, and I want to revisit the issue.
