This bug check indicates that a fatal hardware error has occurred. This bug check uses the error data that is provided by the Windows Hardware Error Architecture (WHEA).
This error is one of the few that doesn't point at any particular component, but based on past experience, the number one cause of this BSOD is a bad OC or low voltage condition. I also note the three GPU's in the system, which is why I ask what the PSU is, since it simply might not be up to the task.
I am running this system on a Cooler Master 700w PSU with 28A on the 2x12v rails I think.

I did realise this somewhat later after my PC crashed in Prime95 after a matter of seconds...The system is now stable at 1.385 processer voltage and 1.425 NB voltage. Is 2.93GHz about the best that my processor can do or is it capable of more?
