Ryzen 7950x3D + MSI X670E ACE - MHz incorrect

[UdoG]

Fresh installed Windows 11, all BIOS setting default.
Is this normal that the max. MHz is around 5300 on some cores? I thought it should be around 5700 MHz on one or more cores?

Seems the problem is a wrong BCLK calculated due to HVCI (Core isolation): https://www.hwinfo.com/forum/threads/core-frequency-reading-in-windows-11.7537/
Also you might rather want to watch the Effective Clock: https://www.hwinfo.com/forum/threads/effective-clock-vs-instant-discrete-clock.5958/

I have the same CPU and Mainboard. I've observed few times (it is rare) a strange behaviour where the CPU temperatures goign up from e.g, 65°C to 97°C (CPU Tctl) withn 1,5 seconds up and back without the other values arround would showing plausibility that this can be real, like the CPU temperature from Nuvoton. I saw also - (negative) temp values or 0°C values.
For the moment i just ignoring it.

I can't confirm the clock issues, it seems to be correct here. If you want, i can check more with you. I assume you also have the only existing BIOS for X3D CPUs, 1.64.
