my micron 5x8 cards (sapphire nitro, se and normal) are doing 34.3mhs 1240/2250 @ 865mv
no mem errors nor incorrect shares
It really is possible and achievable but at the same time...unless bragging... I'm not sure why will I push them so much...
I'd rather prefer to not turn this thread into claymore vs others war and d*ck waving. Lets just pretend that everyone is happy

with latest updates Claymore has the same speed with nVidia as Phoenix.
Phoenix's AMD kernels are more "tweak-able" and are faster than Claymore's.
But Phoenix doesn't work as expected with latest 19.5.1 + drivers. We need an update
On the last part I agree, we need an update for both windows and linux latest drivers + I have contacted developer to add support for ROCm too. Lets hope they are busy doing it
PS: Some phoenixminer results for last.
