This follows on from Part 4 of my step by step guide on how to build a 6 GPU Mining rig. Now that Windows 10 is installed, we can install and setup our miner ready to start mining your first coins.
GPU Monitoring Software
First up you will want to download some monitoring software to check your GPU temps, settings and memory type. GPU-Z is a great piece of software that will tell you pretty much everything you need to know about your cards. You can download this from the following link:-
Once installed you can fire it up and you should see something like this:-
This first tab shows you your card details, including your memory type and clock speeds. For this card you can see I have Samsung memory. Your memory type is important if you decide to flash your cards to get better performance, which I will explain later on.
The next page shows you your live stats, including GPU & memory clock speeds, temperature, power usage and voltage.
Now you will need to download a miner. I suggest starting with Nicehash Legacy to test out everything, because it is extremely user friendly and quick to get going.
First you need to register an account which you can do here. After signing up and verifying your e-mail address, the login should take you to a screen with your wallet address like this:-
You need to copy your wallet address ready to enter into the Nicehash miner software.
Once you have registered an account you can download Nicehash legacy here:
After you have downloaded and extracted Nicehash Legacy, open the NiceHashLegacy.exe file. After agreeing to their T&C’s and downloading a few updates you should get to a screen like this:-
Now you need to paste your wallet address where it says Bitcoin Address. After this you can click on Benchmark.
Benchmarking will run a series of tests on your cards with different miners, to work out how profitable each one is. The Nicehash algorithm will then use these benchmarks to work out which is the most profitable coin for your GPU’s to mine. As prices, difficulty and demand for different crypto currency changes, Nicehash will automatically switch to the most profitable miner for your GPU rig.
Benchmarking takes considerable time and you will need to run all the benchmarks again once your rig is finished and all your cards are overclocked for their best performance. For now we just want to test out your one card with a single miner. You should get a screen like this:-
If you have been following my guide you will only have one GPU connected, so it should only show GPU#1 in the top box. Now deselect all algorithms except for DaggerHashimoto (Sgminer). Tick the box “Start mining after benchmark” and hit start.
The benchmark shouldn’t take too long and once it’s finished another window should open and you should see something like this:-
Congratulations! You are now mining your first crypto currency. Well to be more accurate, someone else is paying you in bitcoin to use your GPU Mining Rig, but I’ll talk more about that later.
You can see your mining speed in the Nicehash dashboard (it will take a little while to settle down to your actual speed). You can also see an estimate of your bitcoin and US$ earnings per day if you left it running 24/7.
Now don’t worry too much right now about your Mh/s, or your estimated earnings, as you are still using the card on stock settings. We will get a lot more hash power once we have adjusted your cards voltage, memory timings and clock speeds which is covered in Part 6.
For now I suggest just running the miner for a hour or so and checking your GPU temperature in GPUZ to make sure everything is working at stock speeds.
When you are ready you can move on to part 6 where we will flashing your card to get the best performance.
