Hi guys, I'm trying to figure out what I'm doing wrong here but have tried basically everything and can't get the rig to mine with more than 1 vega 64.
Here's the basic setup:
windows 10
4 gb ram
32 gb page file
blockchain driver
4x vega 64 gpus
MSI z170 gaming M5
1600w gold PSU
I can mine fine with the index 0 GPU in the x16 slot closest to CPU, this is true even if there are multiple GPUs plugged in, and works for any of the 4 cards as long as they are plugged in to the x16 slot closest to the CPU
As soon as i try to mine with any other GPU, or any combination of GPUs even if the combination includes the index 0 GPU, the system immediately crashes (in less than 5 seconds), and looks like below image:

EDIT: one other thing - if I have more than 1 GPU plugged in, I can't see the HBCC option in wattman anymore on any of the cards. Would love to know what's causing this as well.
ONE thing that could be contributing to the issue (but I have no reasons to suspect that it is even i'm monitoring through killawatt and it seems to be drawing power fine) is that the rig is actually plugged into a 16amp limit US to UK plug adapter (the wall is UK, the rig is US). Something like this:

Just about out of ideas here. Please help! Happy to mine to your address for a couple days before moving it off to the office to join the others if you're able to help get it working.
