In addition, Hotmine kits are pretty difficult to get ahold of even if you have the money for the minimum order amount; many people have tried to contact Hotmine to order the blades and in most cases there was no response. Sidehack also has planned to manufacture Bitfury S1/3/5 upgrade blades in the future, but it will be a while until even the first prototypes are made. Besides these two options there's not much you can do with them to increase mining performance.
Thanks for the info. If you know of any group buys for the hotmine kit or anything like that I would love to know. I think I can get my hands on some extra hash boards. I am going to try and see if I can mate 4 hash blades to one controller. At least then each of my s5 machines will do at least 2 TH/s. Not blazing but for what I paid they aren't horrible lol.
