Holy shit, that's nice man.
Is it stable? Is this ubuntu or you use hiveos/minerstat/similar?

Ubuntu 18.04.2 LTS and AMD-gpu-pro 18.50

Still struggling with 4.15 kernel not able to set clocks properly.
Anything above 1700MHz in P7 state puts the GPU in crimp mode. So I have to use 1700/1030mV in P7 to get the highest possible coreclk. Ideal would be something like 1800/975mV in P7, that would make ~1650 effective clock in P7 at much lower wattage
I learned I will have to upgrade kernel, but don't know which version, there are also complains everywhere about 4.17-4.20 all over the forums.

I'm currently testing stability.

Wondering what would be the eth hashrate with these timings.
Implying on CN algos it gives +15%, 45mh*1.15=51.75mh
Gonna test it later.

Dear god man... forget about the kernels and dial that thing down.  I get this is a dick measuring contest, but you’re prob running 225-250w for that 2100h/s, or about 80-100w more than you would need for 2000, without timing mods (I got 2K @ 837mv.)  +50% power for +5% h/r is not worth it - even if your power is free!
