Every combo I've tried on Polaris (even translating modded bios strap values) results in a crash to blue screen for me. At this stage, I'd say this tool is unusable for Polaris cards.
I have noticed that if you throw out --cl value it doesn't crash when applying string. But without it the hashrate is even lower than stock. So it must be some bug in applying --CL.
Interesting. I guess my point still stands then. Unusable currently on Polaris.
