ryzen BSOD on Ryzen 5 (\WHEA_UNCORRECTABLE_ERROR)

0TBFree · October 6, 2017

Following on from my recent thread*, I no longer have the system lockups but now have experieneced a BSOD (Black Screen)

The system unexpectedly crashed into a blackscreen and then restarted itself, presenting this error name and code in "WhoCrashed".

I managed to obtain a dump if it helps anyone to deduce the issue, but from the careful browsing I've done and what little information I managed to get from the Event viewer, it to me at least, points toward the CPU being the culprit.
