Hello, @Kongrong
Thank you for posting on the Intel® communities.
I am sorry to hear what is happening with your processor.
We can provide you the information of how the cores work and how many you have, for example, your processor has 4 P-cores and 8 E-cores, you can actually verify this information here.
However, if you have any other problems identifying the E-cores or P-cores in your OS or getting messages regarding this, you need to contact the OS developer for further assistance.
Best regards,
Jocelyn M.
