I've been having stability issues using Claymore CryptoNote so I wanted to try out SGMiner.

I'm trying to config sgminer 5.5.5 in Simplemining OS for my rigs.  It looks like it is using the commandline to pass in arguments. In SMOS the default is:

--no-submit-stale --kernel cryptonight -o stratum+tcp://cryptonight.usa.nicehash.com:3355 -u [yourwallet].$rigName -p x --rawintensity 1000 -w 8 --text-only

I would like to change the rawintensity, worksize etc to be optimized for my miners. I have two different setups, either RX 570 4G or RX580 8G.

For the RX570 4G I'm trying to pass a --rawintensity 512 --worksize 4. For the RX580 8G, I'm trying to pass --rawintensity 1152 --worksize 8.

However, when I do this, I see no chanage in performance. Also, when it initializes, I don't see any values changing, just shows: Initialising kernel cryptonight.cl with nfactor 10, n 1024

Right now I'm only hashing at 480H/s on the 570 and 677H/s on the RX580. With Claymore I was getting 630H/s and 740H/s respectively.

I've also seen people change the gpu-threads to 2. Does this matter on the RX570 or RX580 cards? Should I be changing these values too?

Thanks.
