bro, its about your drivers,

install 16.11.2 driver,

if it not fix; try

 first close the automatic ''driver update'' (and also windows update on windows)   (there are videos on youtube about that, its easy)

 download the ''16.11.2'' here:

 http://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-Edition-16.11.2-Release-Notes.aspx

16.11.2 is important, do not use timely new drives on rx470 and rx480,


   if it not fix; try

    restart and install DDU, (you can delete the drivers with this program). delete drivers  (close the driver update, (i m not talking about windows update, driver update is a diffrent thing. )   restart and install 16.11.2

   dont change the riser socket position everytime on mobo,

    sorry about my english Cheesy if you have headache again fell free to asking here or PM

Man i really appreciate your reply but i tried that and nothing :S, in fact the problem is not the 5th GPU, the issue is the pcie x16, when i use my 4 pcie x1 everything is fine.

my mobo is Asus Prime H270 PLUS

5x Asus Strix RX 480  8 GB

4GB RAM

Celeron CPU

and use gpu -z program, and take a screenshot of your card specification and install here, and we can find a custom flash for your cards,  flashing is more efficent, for energy, heat and hashrates

You have to flash your gpu's. There are plenty of threads here and in the ethereum forums with personalized ROMs.

Hello everyone, i have a mobo with 4 pcie x1 and 2 pcie x16, i tried to connect my 5 RX 480, but if i connect just one of them in the pcie x16 slot afterburner wont let me overclock and in fact the hash rate during the ETH mining is very poor but if im only use the 4 pcie x1 everything i smooth and fine.

i dont know if i have setup something in the Bios for fix this issue, please help!!
