Ok we did some quick test now with another R01F resistor (don't try this at home please unless you're experienced in SMT soldering).
This will void your warranty! By changing the resistor to 2.2k gives us 0V74 Vcore. This will push the hashrate up a bit and support higher clocks. We will run a production batch with this resistor to try to bring the cards within spec.
Fans are highly recommended in anything but polar regions 
Meanwhile full sized miner is falling quite a bit short (10-20%) on hashrate, but the powerconsumption is.... 250W AT THE WALL.
When full sized (400gh, 16 boards) fall 10-20% short, i guess so does every single h board? Wow, two times 80-90% is like 160 - 180%, thats 40-45 gh per original uni

plus 250w on 400, thats 60-70w per two hboards. This. Is. Madness.
Im freaking excited!
