I spend about 3 hours but still can't fix it
The MB is h81 btc pro
But it can only use 5 cards to mine
The sixth card can't even detect in windows
But when I opened gpuz,it said its running in 6 cards..why?
Also,when I got more than 3 cards
One of the hash rate will be extremely low,I can sure they are using the same settings
Please help
