I am relatively new to mining and have built several rigs with Nvidia GPUs and so far it is going fine except one thing.
Based on calculators online I should be getting more money for my hashrate than I actually do. My hashrate is steady, and pool confirms it, but i get significantly (30%) less ETH income on my wallet then calculator say so (without other expanses). I use Nvidia optimized Etherminer and tried Nanopoool and Ethmine, both with similar results.
Can someone help please?
