I will not work, PSRAM is dead. buy a new board

@jomjol I did a some tests and in my case, it seems my "dead" board are not dead.
I did cross tests and the result of test depends on motherboard.
Motherboard with only one button makes the PSRAM fail :

With 2 buttons like it works

Maybe this is the issue for some users...
maybe faulty PSRAM for other users : #1295 (comment)
