On another note, I sent one of my Acorns to be RMA'ed, so I'm down to just one 215+.  I asked them for some VRM heatsinks too.
I discovered something really interesting with running one Acorn. 

There is definitely some inadvertent GPU boosting happening when I'm running one 215+ mining, but not boost to GPU mining, but boost to GPU gaming performance.   

I recently got around to running 3DMark tests on my Threadripper/CrossFire VEGA workstation and I am shocked to discover my scores are higher when I leave the AcornMiner running mining Tribus.   No BS.
