Folks,

hopefully, someone can provide some guidance here. Got a rig here full of 6x NVIDIA GPU. Bought a Nitro+ RX 570 8GB, tried installing it, no luck. WIN 10, can't detect it, can't see it in the device manager, never had AMD card on it before so even attempt to run DDU to make sure there's no AMD drivers, no luck. Tried to replace riser, cables and tested it with the NVIDIA card and confirmed not the riser issue. I even tried to put the RX on the NVIDIA riser which I know works and vice versa. Running out of ideas here, any suggestion is greatly appreciated.

hoping to get some feedback from the experienced users. I started with 1060 6GB, looking to add a few more GPU, debating if i should add some AMD for varieties rather as I understand there are range of mining for AMD versus NIVIDIA. mainly using Claymore right now, and seems as AMD is better for ETH.

Love to hear different opinions if i should go with AMD 4GB vs 8GB or NIVIDIA. Seems as the hashrate isn't that much more other than the fact that the card may last longer when DAG files get bigger.

I'm a noob so sorry if my question sounds confusing
