    flash bios. uninstall all your drivers with DDU then install latest AMD drivers. if this doesn't fix it then it is not compatible with your card.

    If you want you can do the modifications yourself on the card. Just save bios with atiflash (atiflash -s [number] name.rom. then edit with Polaris Bios Editor. Copy memory straps from boysie rom. copy gpu, core settings. If you want you can make some fine tuning regards the fan control. Save. Flash. Should be okay now.

    my rig finally turned out to be a 5 card rig instead of a 7 card rig (thanks to the crappy Z170 chipset). So I had 2 cards leftover. of course what to do next. I bought another 3 cards and made another one just like it. And then...:)) of course I bought another 6 cards (since I finally got a H97 mobo). So from the 7 card rig I rounded up to 16:)) but my guess is all of us are doing the same. "Ethereum fever" LOL

    rig 1.
    Gigabyte Z170 Gaming 5 mobo
    5 x RX480 reference (3 cards are actually XFX Black Edition, but reference rom works perfect on them)
    120 SSD
    8 GB DDR4
    Intel Celeron 1151 CHIPSET
    1000 watt Corsair Gold PSU
    USB powered risers

    rig 2.
    Gigabyte Z170 Gaming 5 mobo
    5 x RX480 reference (3 cards are actually XFX Black Edition, but reference rom works perfect on them)
    120 SSD
    Intel Celeron 1151 CHIPSET
    8 GB DDR4
    850 watt Corsair Platinum PSU
    USB powered risers

    rig 3.
    Asrock H97 Anniversary
    3 x MSI RX 470
    3 X Gigabyte RX 470
    120 SSD
    Intel Celeron 1150 CHIPSET
    8 GB DDR3
    1000 watt Corsair Platinum PSU
    USB powered risers.

    hopefully I will stop here :)))))

    Sorry if I'm impolite, but do you mind actually searching for info? Your question has been asked and answered to death since rx480s are around here.
    Get atiflash, polarisbioseditor, download rom from here(search for it, you can do it) flash rom and voila 30-31Mh/s depending on how lucky you are. Some cards need individual settings in biose, some cards can hold 1185 Mhz @ 975mV, others want 1075mV for a stable hashrate at that freq.

    You should mind a gap between performance and a waste.

    30mhs is already a good score in rx480 trying to push it further will cost you a card that you using.

    Ok i understand we all want more money because we can right? Well considering variables of bioses and brands that will change for every one of those rx480s because not every card can easily go 2350 while some stuck at 2150.

    1250\2300 can give you 31-32 but at what cost. %20 higher consumption, degradation, decreasing lifespan, higher temp. I dont think thats a good idea to push a card waaaay further than its limits. 30mhs with 80-100w is a great gain already.
