I am a complete noob when it comes to mining but thought I would give it a crack as a hobby. With my gaming PC which is fitted with a RTX 2060 Super card. I was getting on avg 35mh/s. so I thought I might as well buy a second card with a riser and see what I get from that. I then removed the 2060S card and fitted a RTX 3060 Ti to my PC - this card on it own produces a hash rate of 50mh/s without any OC and keeping this standard.

So when I eventually connected both, the miner confirms both cards but they both together only produce on avg. 40Mh/s??? doesn't make much sense how the one card alone (rtx 3060 Ti) performs better that both together? Probably left out a lot of technical info that would be required by any assistance will be much appreciated.
