Re: PhoenixMiner 5.1c: fastest Ethereum/Ethash miner with lowest devfee (Win/Linux)

For my RX 580 8Gb rigs Phoenix 5.1c didn't create DAG epoch №385. It creates DAG for 0,5 sec and all shares are incorrect. Speed shows normal.

I think PM just didn't support epochs 385+

Looks similar here, since estimated 6 hours almost all shares on ETC-Mining (Ethermine) are invalid.
ETH seems to be working properly, still ...

Doublecheck with NBMiner, no issues! Seems to be a problem with Phoenix only .... oh wait, NBMiner produce many (>20%) rejected shares at ETC-Mining currently ... Huh

I'm use lolMiner now. All fine.

Problem solved by using other miner. Teamredminer or lolminer works fine for me if I run the nVidia and AMD Cards in parallel instances.
It seems PhoenixMiner have a problem on Radeon since Epoch 385. NBMiner as well!

My Rig:

16GB RAM

1x Radeon VII (16GB) >TeamRedMiner
2x Radeon RX 5700 (8GB) >TeamRedMiner
1x Radeon RX 5700XT (8GB) >TeamRedMiner
1x Geforce GTX 1660 Super (6GB) >PhoenixMiner
1x Geforce RTX 2060 Super (8GB) >PhoenixMiner

After further testing with newer drivers and other PC, the problem still persist.
PhoenixMiner have definitely a problem from Epoch 385 on at AMD .....
