To start tweaking the card with watttool i just put the card in system and then run the program in windows, nothing else?
Or is there some other steps like, i need to flash vbios first?
I would appreciate a little step-by-step tutorial just to be sure Wink
I just haven't done this before, only tweaked in msi afterburner which doesnt let you tweak that much. voltage control locked etc.

For wattool there is no problem. You dont need to flash anything.
But to change the memory straps(and get higher hashrate) you need to save the cards bios with atiflash, open the rom file with polaris bios editor. And change the straps. Save the bios file(save as new file, keep the original you saved at first) and then flash with atiflash, reboot.
Which card you have exactly?

600W Bronze running 4 cards? I can only run 3 cards. The system will boot on the 4th but when heavy hashing then the PC will hang. 750W Gold with 5 cards? Interesting...

Probably better configuration for the cards. And maybe slight difference in PSU. And also maybe not dual mining but eth only.

Yes, ETH only. I gave up on dual mining with SIA dropping in value a lot over the past month, and my risers heating up.
Each card is at 1050/1870 - 870/870 with 1500 strap, and the 4 card system draws ~475W from the wall so the 600W Bronze works just fine.

That is quite efficient. It seems that the Ethereum mining might be replaced by the ZCash mining soon.
