I don't have the 2 bios switch, Pulse edition only have 1.
Ouw sorry, I don't have a pulse series. I thought that same as other RX.
You have to disable GPU`s BIOS by soldering a wire between two pins on BIOS chip on card before starting machine, and when booted to Windows you have to enable it again, then you can flash orginal BIOS back again and turn off computer and remove soldered wire. Then start it again and it should be normal.
So you say:
1) Sold pin on BIOS chip;
2) Turn windows on (i've read Dos is better, should i use it?);
3) Flash the original bios;
4) Turn off system.
5) unsold.
Am i right?
If your card still on warranty, RMA would be better, if not you can be tried that method. Someone has tried on this thread.
