I just did what u sed but still my voltage doesnt get locked to 1.06 v. But hovers over that with auto wattman settings. Something is wrong.

Can u tell me any registry entries to delete myself that specify the driver to get voltage readings.

try doing it with display driver uninstaller(ddu) just make sure to do it in SAFE MODE or YOU MAY HAVE TO REINSTALL WINDOWS.

I have a Sapphire RX 480 Nitro OC with VRAM of the type H5GC4H24AJR.
Is it unlockable to 8GB or not? How do I find out?

I wonder how I would be able to diagnose the problem further. Maybe it's the BIOS not being flashed correctly? Maybe the GPU is still using more power resources under Mac or using it differently? Maybe it's not even power issues at all but KEXT driver instability problems (though I've seen others that had success with the RX480 under Mac OS). Any suggestions as to how to tackle to problem? Anyone?

If the flash was successful the modification would be there smile.gif . I have modified value to F instead of D , F is the highest bias I can enable to make the phases powered by PCI-E plugs to have more loading than PCI-E slot. As now the value is differing from windows driver, so it may change it to D when booted into it. Therefore I would always power down and up before going into Mac OSX if you have booted into windows.

Here is increased bias ROM.

No experience of Mac OSX redface.gif . If in Mac OSX you have a SW tool that can read i2c information from IR3567B, we'd be able to confirm if the register that is setting VRM load balancing is being set as per ROM.

Thank you. I can still return it, so what do you suggest, look for a reference card (I have a custom cooler) or get a better one for +€60?
BTW, does it matter if I have a 6-pin or 8-pin connector?

Find your cards limits with Afterburner/WattTool/WattMan, extract your cards BIOS, modify it as needed and flash it back.
I did it,i flashed other bios,xfx,asus,now I am looking for a bios for much oc.i don't know to modify.
