I ordered up a Mining Cave 12 gpu rig (no gpu’s included) because I liked how clean it looked and getting 12 gpu’s running on one rig was my goal. The motherboard is supposed to be setup from them. I installed all the gpu’s, 9 - 3070 ti’s (6 EVGA ftw3 and 3 EVGA xc3) and 3 - 3060 ti’s (Asus Tuf). I was able to set the power limit on everything to 190 watts and I can set fan speed. It mines just fine with those settings but I’m obviously well below the hashrates I should be getting, and am getting on other rigs of mine. The second I set an overclock on one of the gpu’s, the miner crashes and rig goes offline. The screen I have connected to the rig keeps finding shares sometimes but all the gpu’s go to zero MH.
I upgraded the ram from the 4gb it came with to 16gb thinking this could somehow be the issue. Did nothing. I’ve checked all cables and everything is connected properly and risers are obviously working since it mines without overclocking. I tried reflashing the ssd with the latest kernel that all my other rigs are running on (5.10.0-hiveos #83), didn’t fix it. I am updated to hiveos 0.6-215@220409. Nvidia driver is 470.86. I tried upgrading Nvidia drivers to latest version before reflashing the ssd and it didn’t help anything. The rig came with two mining cave 1,600 watt power supplies, the b250 btc-12p motherboard with a pentium g4400 cpu, Kingston 120gb ssd. I should be below the 80% rule on the power supplies with my power limits set.
Anybody with any information would help greatly. I should be getting around 690 MH with the correct overclocks but I only get 588 MH. I should also be able to reduce the power limits of the 3060 ti’s to 150 which would be nice to lower my power consumption.
