Thanks a lot for the advice, sp_!  I understand that you are well versed, please tell me another moment - is it worth trying to change the overclocking of 6700 for results of 50+ or ​​49.5 is this the maximum that is possible?

can you recommend something?  
I have already advised all my friends and acquaintances and sent my results to all the communities and forums in which I am a member, I think that  soon there will be a very good increase in TeamBlackMiner users
