For 4xx cards (Polaris) Crimson 16.12.2 is recommended.
I'm using latest driver.
for 5 hours so far working well.
Except for temp/fan RDP malfunctioning.
Is there any speed up in the latest driver?
top speeds for polaris reached around ver 11 or so...
16.10.4 is better for 4xx as it doesn't require bios signature patch and also one of the few versions that have no issues with accidental 100% fan on various miners(weird, but true) running Cryptonight kernels...
