hey everyone im new to SIGT and SKUNKHASH all together.
im hoping someone can lend me their expertise on my set up, i have been mining for weeks not months but have only been using claymore.
i will list my steps and settings, thanks a ton again for reading!

steps:

1. downloaded client wallet for windows from https://signatum.io
2. downloaded AMD miner from https://signatum.io
3. created account on suprnova.cc for sigt mining.
4. set my bat file with these current lines:

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

sgminer -k skunkhash --gpu-platform 1 -o stratum+tcp://sigt.suprnova.cc:7106 -u hidden.hidden -p hidden -I 20


my current stats in the miner, i assume my hash rate it 19? FYI im running 3 brand new rx580s asus strix all samsung memory an flashed. these were pushing a nice 30+MH/s in claymore for ETH mining.

GPU 2:  52.0C 1401RPM | 19.21M/19.20Mh/s | R:  0.0% HW:0 WU:0.205/m I:20

how can i push my machine to higher hashrates, i read its the -I command line that pushes the cards more?
Should i be using a different miner for AMD cards?
What type of hash should i expect from 580s?
