When I put all 4 gpu, 1 of them have 0Mhz both GPU and Memory clock and gives 4mh/s. When I try 3 of them, still one give 4mh/s. And again when I try with 2 of them, one still give 4mh/s. BUT when I try each gpu separately they ALL work normal. Any ideas? Also almost never same gpu give 4mh/s.
Thanks in advance.

Im using win10 with 16.9.2 downloaded from guru3d, but in afterburner and amd radeon settings it says that drivers are 16.6
I changed this in mobo bios:
Bios -> Advanced -> PCI subsystem Setting
PEG 0 and PEG 1 set to Gen1
Above 4G Decoding set to Enabled
(this one was important for me because my monitor didn't have hdmi cable)
Bios -> Advanced -> Integrated Graphics Configuration
Initiate Graphics Adapter -> IDG
i tried to use integrated graphic card a time , and i get same result msi ab can't set up gpu's
Naturally turn off your miner while you do it
