I've got a Zenbook UX501VW, and it appears that the RAM has some way or the other gone faulty. While running the laptop as usual, it started BSODing constantly, sometimes it even fails to POST and i can't even get an Ubuntu USB to boot (fails with a kernel panic while reading/writing memory pages most of the time).
So i ran memtest and after a few minutes it reported 5500+ errors.
So i went to open up the laptop and discovered that it's soldered onto the board and there's an empty DIMM slot. However, i am guessing that the soldered-on RAM is bank 0 so it will probably always be what the firmware is going to use for POST-ing.
Despite that, flagging memory pages as bad here doesn't seem like a great option because i would probably have to flag hundreds of pages to get it to work properly again. Warranty is also out. So - what can i do? Throw it in the trash?
How likely is it that it's "simply" a cold solder joint? I find it somewhat unlikely that the module just "went bad", unless some regulator on the board failed and killed something on there... not sure...
Is it possible for DDR4 memory to be missing one of the 288 pins and still somewhat work as expected, and POST correctly? (most of the time, anyway)
Or is there a way to "swap" the bank indices using the EFI shell or something like that, and use the DIMM slot for bank0? Not sure what the possibilities are here.
EDIT: just realized this would fit in the troubleshooting section much better, can a mod move this? can't delete/move it by myself it seems
