6 hours into with about 48k MH/S and no block yet. Port 4004 isn't open though I'm not getting any errors - it shows the node as running and error log doesn't throw anything suspicious either. If there's no result in a couple of hours I'll open that port and see if that will do anything.
Also, these calculators are nuts. According to them I should be doing over 1k$ per day...

No - RX480 are supported from 16.xx upwards. 16.9.1 works pretty well for me.

Wow. How did you get 28-29 MH on ETH double mining?
I got 3x XFX Radeon RX480 GTR Black and they only hash about 25-25.5 MH/s Eth and about 35-37 MH/s LBR per VC.

I'm running 3x XFX Radeon RX 480 GTR Black and 1x XFX Radeon RX 480 GTR on one Rig using the latest Crimson driver and claymore's 6.3.
The hash rate per card is approx. 25.5-26.5 with some slight overclocking on the memory.

So far the system runs more or less stable. What difference would a switch to crimson 15.12 make and is it even possible/recommended with a rx 480? I've read they improved the energy consumption significantly with the latest version.

Also, has anyone been able to achieve higher hash rates with the 480s using claymore than what I got? If so, how?
