Can someone help me? I tried graft mining with 6 amd gpus, I started two days ago. But I don't get as much as I should, online calculator says one gpu with 950 h/s should mine 47.45 GRFT a day, so 285 for one rig. But I get much less, only 39 per card or 234 per rig. Miner is rock stable, I get even more, 990+ h/s per card, there is no incorrect/invalid shares, I used that miner for XMR, ETN, Sumo... without problem. I'm on graft.hashvault.pro pool, I see pool is strong, 10.5 MH/s finding blocks frequently.
What's going on?
