My card now throttles because I can't raise the power limit or the drivers will just stop detecting my GPU.
I have an XFX GTR, so I just had to flip the bios switch and everything works, but now it throttles.

Yep, new drivers enforce BIOS checks again.
On an unrelated note, I've been poking around for the optimal frequency on my RX 470 Platinum. I hit a huge frequency wall at ~1100. 1100 takes only 925mv (935mv in wattman) while 1200 takes a bit over 1050mv.
At 1100mhz and 925mv I am seeing core power around 75w with 100% load. 1200mhz/1060mv is pulling nearly 100w. It looks like AMD is outside the efficiency curve by a large amount at stock boost clocks (1206 on RX 470). I am losing only ~8% performance compared to maxing out the power limit and tweaking voltages to hold maximum boost for stock clocks, while cutting 25% off of power consumption (75w vs ~100w).
With the reference -1 cooler (no copper inlay in the heatsink, just a chunk of aluminum), temps never go above 75c with fan speeds never going above 1300 RPM. Why is this GPU not in a notebook by now?
