I used WIN-RX480-31.25-Boysie-v2.rom for my HIS RX 480 IceQ X² Roaring OC 8GB, it worked fine for 5/6 card, but I have faced a problem one of my VGAs is keep slowly drop to 24Mhs after a few mins, i have checked with gpu z, memory controller load is drop from 100% to 80% after few mins, I have set fan speed to 100% but no help
however BIOS 29MH LOW PWR worked fine for all of them
Do you have any ideas how to fix it @boysie
