My point here is that it has worked just fine for months, then for some reason, most likely a couple weeks back, or maybe a bit more, it started to show too low MHz. During this time I have not made changes to the hardware, only changes has been Windows updates.
It MAY have become like this due to updating Aida64 one version prior to version v6.32, I do not know which versions it was, but I do remember updating AIda64 a few weeks back. So it MAY have started then, but I do not know for sure. I just started to notice this in the version before v6.32.
I am having the exact same issue with BCLK frequency showing as 24MHz rather than 100MHz, which results in 9900k frequency showing as 1176MHz rather than 4900MHz. I have no virtualization running on my windows 10 home system, so not sure what is causing the issue.
Incorrect sensor display problems since about 2 versions ago (CPU and RAM MHz)
