I’m using spark pool and Phoenixminer. Recently, I’ve discovered that the share difficulty set by the pool is so high, typically 8000M, that it’ll take a long time to solve the share, since all the gpus are processing respectively, it’s a weird thing that they don’t work together to solve a share because it’ll take 5 minutes to solve a share for a rx580. I’ve tried other mainstream pools, their difficulties are the same except Binance pool, it has a low difficulty around 100M.
But the miners seemed working just fine, they don’t report any stale shares, only few rejected shares. Here are the screenshots from both rig and the pool.
