Anyone have a good .bat file for dual mining ETC + XVG? Or an other Blake2s coin? I’ve try to mine ETC+XVG with this card but the hashrate for XVG was extremely low (200 Mh/s a card) I’ve got a second rig with normal RX580 cards and there is the hashrate for XVG for one card 1500 MH/s

In reply to Andrew Furtas. hi Andrew, yes at the end i had to lower mclock to 2140 to have low memory errors and stable card, but that puts me at 30.3mh/s ... screenshot from the post suggest 31.5 for this bios. Other, hynix one works just fine. Im puzzled :)

In reply to Marko Manojlovic. Hi, try -cclock 1200 -mclock 2250 -cvddc 850 -mvddc 900 or -cclock 1200 -mclock 2200 -cvddc 850 -mvddc 900

Can you post voltages and clocks for Samsung Memory bios you have offered in post for download as the one in the post (-cclock 1200 -mclock 2250 -cvddc 850 -mvddc 850 ) are not giving stable results and are producing lots of memory errors @ about 30.3mh wich is not the same as from screenshot posted for Samsung Bios, above)?

I tried lowering clocks and raising voltages to 950 but same thing happens at lower mh rate.

Thnx in advance
