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. So it must be some bug in applying --CL. Also the timings are reset to default when i run miner. If i apply them while mining - Bluescreen.
