Take a look at the image I've attached. It seems temp is not displaying for one of the hashing boards on my R4. I have tried updating to the latest firmware but no joy. I'm using a Bitmain APW3 PSU. It was working fine then one of the boards stopped hashing and I was only getting 4.3TH/s but after the firmware upgrade both boards work fine but temp doesn't display for 2nd hashing board. Any ideas?
