WattMan can't increase voltage above stock on the R9 380

I used to be able to increase voltage to 1225 mV on the R9 380. Starting from 17.3.1 it can't go higher than the stock 1150 mV. There are reports that the same is happening on R9 390s. My card is an ASUS STRIX-R9380-DC2OC-4GD5-GAMING. I have already submitted a bug report.
