Hey Vargoneti, and luck with this, were you ever able to go above 700? I am in a similar situation... have the same cards. Thanks!

try to add: -g 1 --auto-fan --thread-concurrency 22528
delete: -g 2 --gpu-fan 30-75

if you want to undervolt, download TriXX from AMD site, and try it, card wouldn't be voltage loked

hello ,

i bought one of these 2 weeks ago , after playing with various settings and clock speeds the best i could get ist around 690 kh/s. Could anyone tip me how to go above ?

settings i use currently :

--shaders 2048 -g 2 -I 13 -w 256 --auto-fan --gpu-fan 30-75 --temp-cutoff 90 --temp-overheat 85 --temp-target 72 --gpu-powertune 10

gpu clock 1040 , mem clock 1500 , vddc 1225 (if i try to go lower than 1200 it crashes ).
gpu powertune 10 or 20 did not improve anything.

Any help is much appreciated !
