Did anyone find a solution to the "half the chips on a module stopped working" problem? I believe there are two unlabeled fuses, and the running theory last I checked was one of these might have blown. I can fix the FUSE1 problem, but not the "5 out of 10 chips cold" issue.

Actually, that was only my theory IFF you don't have a single "FUSE1" fuse. In the case where there is no "FUSE1" silkscreen marking and corresponding fuse, then (at least on my modules) there are 2 "P" fuses side by side about in the same place, and I would expect that one goes to half the chips and the other to the rest. If it's on a module with a "FUSE1" board, then I don't have a running theory - could be a loose capacitor to half of the VRM, not sure.

This fix didnt solve my 5 cold chips in 1 board. So it's wasnt the Fuse. I measured the fuse before soldering and it was ok.
In this board only 5/10 chips are hashing.

All 5 chips cant be broken something else is broken in the board. I have 2 Boards with 5 cold chips
Anyway there are the FUSE1 & FUSE2 i sodlered good bypass for the fuses Cheesy

It's hard to tell - did you just connect each end of the fuses to each other or do you actually have solder going across both ends of each fuse?
