Thank you all for your help. I just change the monitor to a GPU at a PCIe 2.0 x16 instead of PCI Express x1 and the five GPU are working at 22 Mh/s (110 Mh/s Total).
Any advice for a better performance? I don't want to overclock GPU. But maybe with other driver.
Now both rigs are using Driver 22.19.162.4. I prefer no to upgrade is performance will be the same.

Also I have other rig with 6 GTX1070 and is working at 27 Mh/s each (162 Mh/s Total). I don't know if this ones are better, or if it the CUDA that makes them work at 27 vs 22 Radeon.

Thanks again.

Drivers will mostly have little to no effect on your mining performance, If you want to get more mhs you'll have to either overclock your card or flash the bios, i recommend flashing a bios because it gives significantly better performance, sometimes with no overclock at all.

Check anorak's bioses here:

and see if your card with your memory type exists and try flashing.
