I have an ASrock Taichi 7900 XTX and I wanted to undervolt for lower temps while maintaining stock performance. By default, meaning sloting it into the system my hotspot would lie between 95 to 102c with an ambient room temp of 26-29c pulling up to 400w. The summer sucks and I don't want a warm GPU soaking heat into the rest of my system. I just realized this card and many other AIB cards have a bios switch, out of the box it's on performance mode. I moved the switch to Q while the system was off and used the AMD auto uv with a -100mhz to the max frequency. By default the max frequency was 3040mhz. This along with the max frequency of 2900mhz there was a drastic reduction to hotspot temps ranging now between 75-89c.

So many ppl that have cards that aren't reference cards complain about high hotspot temps. Most don't thermal throttle and pull more than 350w. So here's a neat uv that should be stable for the most part. Quiet bios, 1125mv, 2900mhz, adjusted fan curve 0 on pw limit, stock vram timings and frequency.
