Pick a pool from the first page of this thread and download ccminer 2.2 (for starters); you will need a Nvidia GPU. Depending on the pool you choose the steps may be different, but most pools have a "Getting Started" section with specific instructions for the coin you're mining.

no calculator that i know about.
you can check in zpool.ca pool interface estimated/current profitability

Old version of Prospector was approximately as fast as Sgminer when mining Signatum. New version should be 4-8% faster.

It can do 18.2 on my GTX 1070, and I have user report of 19.8 on RX 480, making it much faster than Sgminer.

I have 4 x R9 290's and I tried with various options in the sgminer using Windows 8.1, best I saw was about 8mh/s for all 4 cards. A 290 and a 390 are basically the same - with the 390 having more and faster vram. I do have the old 15.12 drivers installed, maybe that was a problem?

I saw a list somewhere suggesting that a 390 should do 10mh/s but I'm sorry I don't know how to set the miner to achieve that. I tried Intensity at 20, 2 threads per GPU, --gpu-platform 0/1/2/-1 and a few other things I can't remember right now but like I said, only about 2mh/s per GPU.

I have an Nvidia rig (2 x 1070 & 3 x 1060) doing 80mh/s.

So I am also interested if anyone has any suggestions about getting AMD hawaii cards to hash SIGT faster?

Do you have a rx480 with 4GB or 8GB of ram? What OS do you use?

This project needs one. Someone should build one. Good idea!

How can I set worker name at this pool?

I do not think you can find an working amd miner.
