A few generic troubleshooting steps I'd try..
1. Remove all but one GPU
2. Fresh install of SMOS
3. Add one GPU at a time, overclocking each one individually
This might narrow it down to a bad GPU, or riser, or PCIE slot.
Hi, thanks for your advice!
How can I overclock gpus individually?
Just separate the numbers by a comma, no spaces.
For example let's say you want to run GPU0 at 950, GPU1 at 950, GPU2 at 900, and GPU3 at 950 you would enter 950,950,900,950 in the Core MHz field. Same goes for the Memory.
