What's your wattage pulling on those guys? Are you running 100%? Someone should runs some tests around 70% power limit and report back for equihash and skein. I've been debating pulling the trigger on a pair of these since they were below $1200 msrp, but tax brings them right back up to $1200/each. I still find myself wanting to seal the deal but need some convincing, that adds quite a lot to the ROI at $4-6/day.
Why on earth would I cripple them with 70% power? I'm at 120% power, +120 core, +500 mem each. I posted a whole slew of benchmarks a few pages back (although those were at +100 core). Depends on the algo, pulling about 280w each right now on Phi. I've seen it as high as 308w
lol i have 50 nvidia cards and I run none of them over 70% TDP
you must not care about power draw
my founders ed draw only 150 watt max
you will find that the hash rate on 10x cards down not vary that much from 70% - 100% tdp
I still get 38 mhs on the star wars with 70% tdp, heck I can run them at 65%
what really raises hashrate for and zcash is memory not the core power
