best mining motherboards

Choosing the best motherboard for your mining rig is a crucial step that some new miners tend to overlook.

Just because a motherboard’s specs meet the required amount of PCIe lanes doesn’t mean its bios settings will support mining of a multi GPU configuration.

However, with the support of several manufacturers, you can now purchase motherboards designed explicitly for mining cryptocurrencies.

With many different variations of mining motherboards to choose from I decided to put together this guide of which motherboards are best suited for GPU mining as well as my top 4 picks of mining motherboards too date.

In the end, the best motherboard for mining in 2021 can vary depending on the end-users specific needs and more importantly budget. For mining with a server case frame then one might choose BIOSTAR TB250-BTC D+ due to its no riser architecture, but for most mining rig builds these days, the ASUS B250 MINING EXPERT is going to be the best option.
