If you connect this video card to the 16x port, then there should be no problems. I have no data on how this video card works through the raisers. But the payback period of this video card now is - never.
It is on the x16 slot but it is not recognized by the motherboard, I don't know why.
The temperatures are okay, you can check on my videos mining different algos: RTX 4090 Hashrates Playlist - https://www.youtube.com/watch?v=561nJJrl2Xk&list=PL0X8pLdX8UE6dOZrgrUk9bV3YOAKk9HKI&index=1
Nice video. I gave you some merits
For this video card, you need to come up with a new coin on a more adapted algorithm for core performance.
It is pretty much like the 2080ti was to the 1080ti.
As a mining device it is crap go find a 3090 better yet get a pair of 3060ti's
