Want to create a cryptocurrency mining rig? Whether you're mining Bitcoin, Monero, Litecoin, Dogecoin, Ethereum, etc. it's a good idea to get a gauge on what your processor can handle. Even if you are mining with a graphics card, your CPU might be strong enough to mine an alt coin at the same time!
Instructions:
1) Make sure any CPU intensive programs are closed (unless you want to test under load). If you plan on running for longer than 30 minutes it would be advisable to turn off automatic sleep in the "Power & sleep settings".
2) After opening "What is my hashrate?" set your preferred settings (they can be changed on the fly while running as well). Keep in mind most CPUs have two threads per core.
3) Click "START MINING" to begin. Leave it running until the hashrate has averaged out and the graph is relatively flat. This time varies between computers. Since you should not use your computer while the test is running, it is advisable that the test be left running overnight.
