Which MoBo do you guys recommend for multiple GPU mining?
B75 BTC Mining Motherboard
https://www.aliexpress.com/w/wholesale-B75-BTC-Mining-Motherboard.html?If you don’t want to pay a lot of money and struggle with the settings, then buy a ready-made kit in China for 8 video cards.
These motherboards see all 8 video cards without problems, but if you need mining for 2-3 video cards, then almost any motherboard with the necessary connectors will do.
