I have set up a mining rig with 6 GPUs of RTX 3070. As shown in the image below, GPU #1, is performing at half the expected hashrate of 28 MH/s. I am also attaching my AfterBurner settings with power limit at 69%, core clock: -10, memory clock: 1160.
The rig is set up with a 1500 W power supply that I bought here: https://www.amazon.com/gp/product/B01KP8S83C/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1
In the nicehash tool when I disable one or two GPUs, the GPU#1 starts to perform correctly at 60 MH/s but when all 6 are enabled then the first one operates at half the hashrate. Can someone please help, I am going crazy.
