If you only use one of the two cards without others, will it work? And when you use PM to specify -cvddv, do you specify one value or three values such as -cvddc 800,800,800? Note that space is not allows between the numbers. It causes PM to crash when I tried it with 5700XT.
Thanks for your reply.
The card that works fine will work fine by itself or when in a rig with other cards.
The cards that don't work as expected behave the same if they're in a rig by themselves or with other cards.
The same cards fail regardless if I specify the voltages together or individually (eg. -cvddc 800 or -cvddc 800,800,800).
I have reinstalled drivers, reset all the settings for all cards in radeon software befopre running the miner, etc etc.
It feels almost like 2 of the 3 cards have some kind of different hardware on them that regulates voltage and isn't very well supported by phoenix, but that seems pretty unlikely given they're all the same brand and it's a new card...
I've been advised to use the -eres flag since my 6800s used to have problems when DAG regenerated. I use
and I've since found my cards to be a little bit more stable.
