Resolve the persistent LED flickering on MSI MEG X570 Ace during debugging.
Resolve the persistent LED flickering on MSI MEG X570 Ace during debugging.
It rarely leaves that 35-37 range. Are you certain it isn’t running in a mode that shows CPU temperatures or other diagnostic outputs instead of debug messages?
Can't provide further advice without checking the manual for the board. The variation within a tight sequence of numbers (mid 30s and now low 40s) seems like a clear indication it's detecting a system "vital statistic." Once the OS starts, the debug screen is mainly for diagnosing issues during boot. I've noticed some boards consistently showing "AA" or similar even when Windows was running. It looks like someone at MSI might have thought it would be useful to change what the display shows while the system is active. Try stressing the system with a benchmark or a demanding game and see if the number changes. You can also use HWinfo64 or a similar tool to verify the value.
The X570 ACE manual lists debug codes in the 30s mainly for post-memory CPU setup. The 40s are mostly reserved for wake-up from sleep mode and aren't used for debug purposes. This supports my belief that the display is interpreting something different, even though it's unclear why this detail isn't documented. Unless someone with a similar board or a recent MSI model can share insights, I suggest seeking help from an MSI-specific community.
I'm seeing the same board with temperatures around 55-60, and after installing Ryzen Master it aligns with the reported readings. It's probably due to the GPU and pump blocking the sensor.
