3 Blocks a Day with a i5 ? What is your h/s ?
average 90 H/s
Me to with i7 4770k 4T actives before 3 blocks a day but now 1 blocks day only

Something not all right....
Intel Core i5-6600K, 32 GB RAM
How has the configuration of miner ?
I'm mining with a i5 can't tell you what model & how many GB of ram at this point in time but with the
setgenerate true -1 command entered into the debug console it gets between 67H/s-70H/s no tweaking & finds a block maybe every day or two.
