Here is what i did
5x Sapphire RX580 Nitro+ 4GB Hynix
First of all i have installed drivers. Win10-64Bit-Crimson-ReLive-Beta-Blockchain-Workloads-Aug23 from official AMD site
Then Bios.
Bios switch - little sitch on my GPU moved to the Outputs (hdmis dvi)
Then i flashed bios. the one from Anorkas site powersaving bios with little mod.See pic.

after that i just restarted PC
i went to watmann on my radeon driver settings driver setting and i OC GPU and MEM manualy GPU-1170mhz MEM-2100MHZ(crash on 2150 and higher also for 2100 extra cooling helps so it's more stable) - voltage values i left AUTO
IN ethminer i set
ethminer.exe -G -F

MY EMAIL IF I WANT TO --cl-local-work 256 --cl-global-work 16384pause
value
--cl-local-work 256 --cl-global-work 16384 should help i did not tryied without it to see if it rly helps
My results are in ethminer test mode im mining 28MHs each gpu, and now my 5x RX580 rig is taking from the wall around 730W where before mod it was 920W si its nearly 200W less !!!! Im happy with that
dwarfpool shows me that my rig is mining average 140MHs sometimes higher sometimes lower but its doing good job mining at that speed and using 200W less !!
sonn ill do some tests on Claymores
So far if i try to mod some CLocks and Voltages on claymore command line it crash!! so just do
EthDcrMiner64.exe -epool
POOL ADDRESS:PORT -ewal
WALLET ADDRESS -epsw x
CLaymore and settings IMG
