I haven't mine cryptonight coins for long time. I wanted to switch for haven, but I'm getting only 400h per card (rx580 8GB).
I can set intensity to 270 and get over 1200 per card but SRBMiner is not submitting any hashes then. Anything over 50 intensity is not submitting any hashes (tried worksize 4, 8, 16, 32).
Any ideas?
