Dogie, in your Ares 256 review you recommended to set difficulty to 16000+ in Ghash.io pool settings. I tried increasing it to 51000 and the miner is now capable of up to 360 MH/s. Two Ares units output 680-720 MH/s, while retaining the same power consumption! Note: environment temperature is 22C.
IYFTech, regarding the Uranus, you can write whatever you wish, but I personally know HC are building two datacenters for this model. The miner exists thats a fact, visit them to make that certain for yourself!
