Hashing on SGminer with standard clock GPUs mining SGB - this pool rejects a lot of shares. I mean a lot of shares. Same miner same settings on any other DGB pool and it's all sweet.
I have similar troubles , difficult to understand . Mining dgb groestl with nvidia and ccminer on the blocks factory - works fine. If i use sgminer with amd (rx470 )no way to get any share. On suprnova works well sgminer but no way to make it run with nvidia.
Admins are in holiday ?!
Sorry, I don't have an AMD card to test.
