That seems likely as you seem to have another chipset. The changes here are mostly correct (see notes) for the NCT6686D chip. What you do have though, I'm not sure. I cannot find it. Perhaps you can check your motherboard physically and see what's written on it.

Following up here, I tried running this nightly and also do not see displays show up with my B650E PG-ITX. Will try charging this back to 0x41

I can confirm what @intositeme saw, only seeing information display on my B650E PG-ITX WIFI (Windows 11) if I change this constant back to 0x41. Created a new ticket #911 for resolving. Much appreciation for this initial support / reverse engineering.
