do you guys mine this with asics or gpu? I only have gpu, 6.6 on r9 280x and 9.1 on r9 390. I've read the r9 390 can do 15-25mh but can't replicate that, what hashrates you guys have ?
The developers create costumized software what can make much more speed. The way to get that, is buy it from the devs like w0lf.
Dont know the price, i toucht 0,5 or 1BTC for that software.
They optimized (for what i know) the GPU drivers or something, they getting 2-3x more speed then i do with the ''free'' miner.
To do that, u must have many knowledge about developing on GPU software, if you dont, u will never get that high speeds. Unless you pay the miner developer enough to get that same software.
What people mostly do, they rent a rig on miningrigrentals.com there u can rent like 100mh/s.
I talked with w0lf a time ago:
I am selling it for 0.25 BTC. I could tell you some of the edits, but you wouldn't really get it, or if you did, not how to implement them.
Heavy modifications to the GPU code (in OpenCL) and some light edits to the host miner code (in C.)So its about that modifications to the GPU code, on that way they get much more performance.
It's a great guy what like to help people (most of it he is know about his free good working miners), but u can pay him for 100% optimized software.
In short words: Yes you can get 20-30Mh/s with ur R9 390, but u need to edit your GPU code (in OpenCL). U can not get that speed with just add a line in the .bat file. If you want that high speeds, u must contact w0lf and pay him for let him optimize your GPU code.
I see GREEDYJOHN dont understand ur question, my answer is the answer on your question.
