I have windows 10 with Claymore miner. Mining eth in nanopool. I have 6 cards running on the new rig, it has 8 installed but I cant get the M.2 pcie risers to work. Maybe windows 10 needs to update as the 2 cards are not recognised by the device manager.
Are you using ASUS PRIME Z170A Motherboard? and the right M2 to pcie?
I have the Asus prime Z270P motherboard and M.2 to pcie x4, then normal pcie 1x riser to 16x for the card as in all the other working slots. I'm gonna watch some more youtube videos to see if I can find a solution.
ASUS PRIME Z170A is the recommended for the 8 GPU set up, I think that is you issue, sell you MOBO get the right one.
I'm gonna stick with the Z270P (thanks for your advice.) I got 7 cards recognised at startup yesterday. I had to grind the front edge off of the M.2 connectors to get them to contact properly. The PSU is 1200w, it may not be enough to mine with 8 cards but it will be enough to start a system with no load on the cards. I also have a link cable and spare 550w PSU I can add if I need to.
My rig has 6 1070 750w on eth 70%, and 980w 85% equihash, you might be able to mine with the 1200w, but put some cards on the 550 for sure. What Model GPU you have?
When I started mining a couple of months ago I bought a 1070, it seemed to have the best ROI but I saw that a lot of people were using AMD cards and getting about the same hashrate, so I looked at AMD and I realised that the rx470 8GB was about £100 cheaper and decided to use the rx 470's due to the much faster ROI. At the moment I have a small rig (my first) that runs 4 x rx470 and my new rig that has 4 x 470s and 4 x 480s, my hash rate on the small rig is 110 and my new one on 7 cards is 184, all of the cards are bios modded but they still need to be undervolted and tweaked for performance. I've been working on it for days now, it's almost like having a full time job. : )
The same happened to a friend in the Dominican Republic with AMDs, Nvidia way easier to OC UV.
I agree, I set up a rig for a friend the other day using nvidia cards and it was much more straight forward. Once I've done the initial setup with amds it should be ok, it's just a lot more fiddly and sometimes frustrating.
