any ideas to get 28-30 mhs?
Increase RAM clock to 2200 (or close to that, what is stable for you)
Decrease GPU: 1200 MHz
Decrease TDP: -10%
With bios mod, it should give you 28-29-30 depending on the driver/miner version. (I suggest latest available from both + Creative Update for Windows)
You cannot get 29-30 anymore with this card. You are 2 months late. That's because of the hashrate dropping for AMD cards on each epoch. The actual rate now is somewhere 27+. If someone else has better hashrate for this card, please share the bios.
yes you can. my powercolor 470/4 samsung gets 29.3. just strapped 1750 upward. 1040/2100 clocks. my msi 470/4 with samsung gets 27 with same settings. not sure why the msi is lower. kvm is plugged into the powercolor
also this is dual mining sia -dcri 15 setting. each is doing ~400 mhs sia.
so all i did is the memory straps, nothing else in the bios was touched except i raised the power limit from 5 to 25 on the powercolor.
it is possible the 29.3 mhs rate is an error possibly? however rig is stable for weeks at a time, and that card shows no artifacts when displaying the desktop.
EDIT: nevermind, wrong card.
