I'm going to run it on my 6xVega rig for a while.
It's on a riserless Onda D1800 board sporting a very shitty CPU so if there are any bottlenecks, I guess I'll see them happening.
At the moment it's chugging along at 12.2kh/s with less than 20% CPU usage.
24 hours later, zero crashes, no slowdowns.
CPU usage at 10%.
I then increased core clocks by 40Mhz to gauge the difference. 100W more total power draw at increased voltage and the gains, while non negligible, were still too marginal to make up for the difference, imo.
