Thanks for your report.
Sensor values for this mainboard shall be fixed in the next (Beta) build.
But I'm not sure what happened to the UCLK - does it always show such value, if not when did that happen?
I think it just happens when I run HWiNFO64 for a long time (for a couple of hours). The values are normal at first but then negative values show up
It might have something to do with the fact that I was stress testing my RAM, but I think my RAM is stable as memtest doesn't show error even after 5 hours
Thank you for the fast response! It is working now, but the value seems a bit lower than what I set in bios and what the Asrock software reports. I don't know which is more accurate, that's just what I see
