I just want to share my experience on here for people who might be new to crypto mining, I spent hours on trying to find what could be wrong with a motherboard day ago, if you are using a gigabyte motherboard or planning to don't waste time here are what I noticed will be a challenge for you
1. Without changing gen to gen 2 you will have problem
Imagine loading up windows and everything start acting weird once you connect more than on GPU on board, crashes and lagging here and there, the fix is gen 2 activation
2. You using a new model GPU like RTX series? They can start getting abnormally hot for no reason if you use the two pcie 16x slot which was meant for SLI/Crossfire, the fix is still the gen 2 and if you have 3070ti make sure another 3070ti goes into the second SLI/Crossfire slot, don't insert gtx card in one and RTX card in the other
This could sound weird as it was to me buy gen 2 solves my problem, mind you I have other motherboards that are presently mining with none of this issues, this is my first rodeo that's why I decide to share, who knows? Might help someone
I don´t understand why people change the pcie to gen1. This is not needed, in any case. You can always stay on the highest pcie generation. And this has nothing to do with gigabyte mainboard. You using an very old mainboard and that is the problem.
SLI is not supported by the rtx cards, so it don´t care what slot you are using.
