I'm stunned that "mapping out" blocks of bad RAM is a thing you can do. It reminds me of the old days when hard disks had to be "low-level formatted" first (ask your parents, kids) and it would ask you for a list of bad sectors to map out. Sometimes hard disks would even come with a list of known bad ones printed on the top.

The race to make laptops thinner is pointless. I wish I could buy a thicker laptop that is more robust, repairable, expandable, and has better cooling, with the extra space filled with batteries.

DRAM problems used to be a common thing, at least AFAIK in the 90s up to early 10s. I wonder if that still the case or is it now a non-issue for the first 5 years of usage. Our Watch, iPad, Phones all have more memory than old computers. Even Apple Watch Ultra now has 4GB of memory which I thought was crazy.
If it is not, how would all these appliance with memory doubt with bad memory?

It is fairly simple business to desolder the old BGA chip and replace with a new one.
There are specialized shops willing to do this around the world. This is especially common in third world countries, Eastern Europe, China etc.. There are people who would do this change for around 5-10 USD in India (as long as you can find the replacement yourself).
I am amazed at how many people on this forum think of this as some scary dark magic.

We used to buy Dells with minimum RAM and add quality third party RAM for way less than Dell wanted for it. They also use ram quantity to leverage other specs we're not bothered about. Of course they are moving to soldered.
