Ok today we are finding out once and for all what causes an issue I've come across multiple times... This won't be for the faint of heart...
This is a series X and this series X crashes when you fire up any triple A title. I've swapped it's PSU, I've cloned it's SSD and still it continues to crash.
Next to it are some donor boards I've harvested an Ethernet and some other bits from... Anyway I want to find out once and for all what causes the crash.. I suspect it could be one of two things.
1) Possibly the vrm fails to deliver power and the machine crashes (I think this is less likely but possible)
2) Memory, the series X has a dual memory subsystem with the majority of its memory 10gb running on a 320bit bus at 560GB/s and 6gb on a 192bit bus running at 336GB/s, could it potentially be that when a game pushes memory and hits that secondary subsystem?
Now I don't know the answer but I do have a donor board and I'm not bothered if I cook it... It's time to potentially find out...
I think straight off the bat I'll just swap the entire vrm from the donor. If the issue remains I'm going to swap one memory chip at a time until I've done them all or I've found the bad one.
To start let's pull off all the power stages mosfets..
Just pop them off and lay them out

do we even know these are fully good? Not really but who cares, this is likely not going to end well and if i kill it I kill it for science.
This is one of the VRM's
This is the other...
And goodbye memory...
Right this is all the parts we might need.
Put simply we are either going to work out what causes this issue or we are going to break it. To be continued....
