Re: [ANN] [HVC] Heavycoin - Ultra-secure, Decentralized Block Reward Voting, Fast

i'm having 3 290, with the newest miner,each can reach 21m, but one of the 3 doesn't work, anyone has some ideas about this

Does it list the card as "off" in the cmd window or does it show 0 hash rate? Try restarting your computer.
