Does your miner show any errors?
no errors..... and no shares.
tried on "pool.mn" same story. 0 valid 0 invalid. Efficiency 0.00%
nothing accepted in miner.
honestly i kinda hate sgminer.... that is not optimized for amd at all. on any coin i ever tried it shows 5-10x lower hashrate compared to performance of similar nvidia cards.
(last example was chc ..... people with one 750ti (!) was getting better performance than my 7950 - thats definitely can't be right).
Maybe because AMD is only good at dagger hashimoto, cryptonight and a bit on equihash? Nvidia is extremely better at most algo's. I seen coins where a 1070 does x10 better than any rx card.
