gigabyte 7950 v1 1050/1300 220H/s, Sapphire vapor x 280x 1100/1600 265H/s
moded bios.

Your bios mod for 280x sucks, Sapphire 280x @ 1085/1625 = 305 H/s (Hynix), Elpida gives even more...
Stock clocks with bios mod gives ~270 H/s ...

Hello guys. Little help please

I run 3x470 + 2x390 system with h81 pro btc. But I lost some hashrate on the 390`s. It shows me 295 h/s with 16.9.2 driver. I tried with 16.12.2 but the system fails when load desktop. Any idea which driver will go 3xx and 4xx series and keep 350h/s for the 390`s?

Put 470 card in x16 slot, and the rest 2 next in x1 slots, 390's in rest 2 slots.
Should be fine. Pay attention that "synchronize similiar cards" option doesnt work correctly on newer drivers.
Uncheck it and set each card manually.

p.s. 16.11.1 Drivers give normal speeds in Polaris/Tahiti combo's, tested.
