Overclocking a mining Rig – do I have to overclock each GPU?

Review Contents:

Last updated March, 2018

If you have a GPU mining rig that you want to overclock, you’ve probably wondered if you could overclock the whole rig, or if you have to overclock one graphics card at a time?

The answer is yes, you have to do each GPU separately – sort of. Depending on your overclocking software, you may be able to ‘link’ multiple GPUs together, so that when you adjust the overclock setting it changes many of them. Using the MSI or EVGA overclocking software allows for this.

Another option is within the mining program itself, where you can set overclocking parameters. This can vary from software to software, so you’ll have to look into the docs of the specific mining program to find out – sorry!

However, if you have a little bit of extra time, and you’re interested in getting the most out of your GPU mining rig, then you should overclock each card separately. Over and over again, I come across stories of people who have multiple GPUs that are the exact same brand and model, and yet they respond slightly differently to overclocking and undervolt settings, simply because of variations in the silicon production processes.

What do you think? Do you agree or disagree? Do you have real-life info to share?
