Got them running around 666 sol/s or 10200 sol/s total now as I dropped the powerlimits to reduce heat and noise. I have mostly founder's editions as well as a few gigabyte gaming OCs, 2 gigabyte turbos and two pny 1080ti blowers. Overclocks don't really have so much affect on hashrate with equihash I believe, but everything is running at 150+ core and 450+ memory.
