Re: PhoenixMiner 4.9c: fastest Ethereum/Ethash miner with lowest devfee (Win/Linux)

20.3.1 for now,tested one befor and had same problem

Try to remove options
-openclLocalWork 128
-openclGlobalMultiplier 4096

I use -openclLocalWork 32 and don't get incorrect shares. I have been down this path and no matter what you do, you will always get incorrect shares with the value higher than 32.

I don't see any difference at all when using -openclLocalWork 32.

For the older cards (RX470/480/570/580) the default openclLocalWork is 64 and you will get incorrect shares for higher than the default 64 value. For the NAVI cards like RX5700(XT) the default openclLocalWork is 32 and you will get incorrect shares for higher than the default 32 value.
