@Eliovp: Tested your ROM with ETH and ZEC, stock clocks, undervolted and underclocked...
Conclusion: No changes, still getting exactly the same results as the other cards with stock BIOS.
Anyway, no complaints. Thanks for trying!
Cheers!
Haha, i honestly was thinking, no way, that's impossible.
So i checked the rom i uploaded, of course, it's the wrong one

Will upload the right one as soon as i get at my office.
