My hash rate constantly fluctuates between my 3 AMD cards. I have 2-RX580's, 1-Vega 64, and 1-1080TI. The 1080TI is very stable and constant. Between the 3 AMD cards the hash rate constantly drops. I've tried uninstalling/reinstalling drivers. I'm currently running the Relive drivers. Switching to regular drivers does nothing. In GPU-Z the memory controller load drops sporadically goes from 100% to 0% for the 2 580's, and the GPU load on the Vega 64 drops from 100 to 0 as well. I thought maybe my 1000W PSU was the issue so I hooked up an additional 850W PSU, and still the same fluctuations. I'm using Claymore's Miner. Any help or advice is appreciated. Thanks.
Try to check these:
- GPU hardware errors, install Hwinfo to check errors
- Mem clocks and CoreClocks, you can adjust to designated clocks, if you haven't done thru Bios mod
