Today I launched Phoenix miner 4.1c in dual mode with blake2s on three R9 290. They recently gave about 23 mh/s on Ether in solo. Unlike the RX series, there is no support in AMD drivers for a large DAG size for old cards, so their speed, which was once 30-31 max, has seriously decreased. Got a fantastic speed in the miner window (45 mh/s). Blake2s showed 1300 mh/s, but there were no shares at all.
I was very pleased, but after checking on the pool (Ethermine) it turned out that these are only numbers in the miner's console. The real speed remained 22-23 mh/s as it was earlier.

We have tested extensively with R9 390, which is virtually the same as 290. Most probably your drivers aren't recognized properly. Please check the logs - you will see a yellow warning message "Unknown OpenCL driver version! Hashrate and stale shares may suffer". Here is the list of supported drivers for Windows: 15.12, 17.7.2, 17.8-BETA (Blockchain drivers), 17.8.x, 17.9.x, 17.10.x, 17.11.x, 17.12.x (avoid these, some bugs), 18.x.x, 19.1.1
If you are using one of the supported drivers but the problem still persists, please send us the first few pages from the log file to diagnose the problem.

I am using 4.0B without any issues.
Does this only affect if the miner crash and have to restart?

The DAG issue was already solved in 4.0b (it supports DAGs over 235). So, you don't need to upgrade unless you want some of the other new features.

Just wanted to post a little thank you for your continued work and the new turbo core.

Using 4.1c with the 19.1.1 Adrenalin drivers and my RX580... stable all week and hitting just slightly over 32 MH/s.

Thank you, always nice to hear!
