New update if this tells anyone anything - I am still getting the failures with constant resets. Last night I had these running for 12 hours or so and it had cycled through nearly 180 of these errors:

And so on for hours on end. I found it when I woke up today and restarted everything, but one of my miners is getting that failure error every few minutes or so. It successfully starts again at 100mHz and eventually goes up (I have them set to max 150 right now to make sure overwork isn't the cause of this) until it resets again. Cycling through this process means my overall hash rate is about 10-15 less than it should be when averaged out... plus the unsettling feeling that one of these is on the verge of breaking...
