Greetings. Who can explain why, after adding 6700xt to the previously working RX478, on the air in Phoenix Miner 5.8c under Windows 10, driver 21.4.1, ping 45-70, Phoenix began pouring stales, (there are no stales on the statistics website 2MINERS.COM) I turn off 6700xt - everything is fine, there are no stales. I don't understand how a new card can do stales?

rx 6700 xt uses best -clkernel 1 and -rxboost 1 is for polaris cards. If PhoenixMiner -list shows
rx470 as gpu1 and rx6700xt as gpu2 try this:
PhoenixMiner.exe -coin eth -pool eth.2miners.com:2020 -rvram 1 -wal 15bYe_______toB4.r1 -proto 4 -cvddc 1:0,2:870 -mvddc 1:0,2:870 -cclock 1:0,2: -mclock 1:0,2:2090 -tt 65 -fanmin 1:30 -hstats 2 -clKernel 1:0,2:1 -rxboost 1:1 -fpwm 2:4
1=rx470 2=rx6700xt
My settings for rx6600xt I use under linux are:
Phoenixminer -amd -acm -clKernel 2:1 -hwm 2 -tt 2:60 -ttmem 2:70 -hstats 2 -fpwm 2:4 -cclock 2:1100 -mclock 2:1170
I don´t set the cvddc and mvddc as the AMD driver under linux takes care of that automatically.
