How to Find the Hash Rate of a GPU for Mining Ethereum on Windows

I have a laptop with the GeForce GTX 980M on it. I want to find out what my hash rate is to see what my profits could be from mining Ethereum over the Windows platform. Here’s how to do this:

  • Download the latest release of ethminer. Make sure to download theĀ Latest release and not theĀ Pre-release. Unzip it somewhere.
  • Open the command prompt to where you downloaded and unzipped ethminer. Run the ethminer -U -M command:
 C:\Downloads\ethminer-0.11.0-Windows>ethminer -U -M
 Using grid size 8192, block size 128

 Trial 2... 12578719
 Trial 3... 13273113
 Trial 4... 12570341
 Trial 5... 13277536
 min/mean/max: 12570341/12995449/13277536 H/s
 inner mean: 13043122 H/s
  • The inner mean is your hash rate. I’m sitting at about 13043122 H/s, which according to some online mining profitability calculator, could earn me about $30.45 / month if I don’t have to pay for electricity.

I'm not entirely sure what makes me successful in general programming or development, but to any newcomers to this blood-sport, my best guess would be that success in programming comes from some strange combination of interest, persistence, patience, instincts (for example, someone might tell you that something can't be done, or that it can't be done a certain way, but you just know that can't be true, or you look at a piece of code and know something doesn't seem right with it at first glance, but you can't quite put your finger on it until you think it through some more), fearlessness of tinkering, and an ability to take advice because you should be humble. Its okay to be wrong or to have a bad approach, realize it, and try to find a better one, and even better to be wrong and find a better approach to solve something than to have had a bad approach to begin with. I hope that whatever fragments of information I sprinkle across here help those who hit the same roadblocks.
