Mining rig

A mining rig is a computer system used for mining bitcoins. The rig might be a dedicated miner where it was procured, built and operated specifically for mining or it could otherwise be a computer that fills other needs, such as performing as a gaming system, and is used to mine only on a part-time basis.

Tips

• Motherboards with on-board graphics (also referred to as integrated graphics) often are either problematic or unusable when more than one GPU card is installed. Choose a motherboard with no on-board graphics.
• The following component lists might be used to help in building a new rig. To minimize shipping costs, components from the same supplier were preferred over compenents from the least expensive source.
