Two days ago I undervolted my 6800 XT from 1150mV to 1120mV and overclocked its VRAM to 2150MHz with fast timings with Adrenalin. These settings seem stable, I haven't crashed once in Cyberpunk 2077 these last two days and haven't had a driver crash either. At first GPU-Z was working fine and showed me all the sensors and read frequencies with no problem when I was testing and monitoring to see the impact of the UV/OC on the card's behavior, but yesterday it stopped reporting frequencies and half the sensors (such as fans speed and GPU power draw and voltage) I had the previous day were missing. Frequencies are missing from both the "Graphics Card" and the "Sensors" tabs.
I don't think I updated GPU-Z in between, I believe I was already on v2.55.0 from the beginning. I rebooted the computer and redownloaded the app (I use the portable version) but it didn't change anything. Adrenalin and HWiNFO are both able to read the frequencies (though I know HWiNFO doesn't use the AMD API to read sensors while GPU-Z does).
