Activity Monitor showing double the cores

[CjBerg]

Been running the mackintosh for a few weeks now, starting to get everything dialed in and working on smaller and smaller issues. For the most part, everything has been really smooth, my biggest problem getting software licenses transferred to the hackintosh.

When I open Activity Monitor, it shows 16 cores, not 8. Every other core is inactive, and it shows 8 active cores. In thee system profiler, it shows properly the i9 and 8 cores.

This is more than a cosmetic issue. I checked some of my software and it is thinking there are 16 cores also.

In Clover Configurator, I have the cpu set to 0x1005 fr an i9. When I originally started the machine, it showed it as an i7.

Any ideas where to look to set the cores correctly?

Thank you,
Cj

@CjBerg,

Nothing is wrong,

Your Intel i9 9900K CPU is a 8 Core / 16 Thread CPU, for each core there are two threads.
In the CPU world this is known as Hyper-Threading, Intel has a good article on it here :-

Intel® Hyper-Threading Technology

Intel® Hyper-Threading Technology uses resources efficiently, enabling multiple threads to run on each core and increasing processor throughput.

www.intel.com

It's quite normal for Activity Monitor to show the activity on all the CPU threads, 16 in your case.
Where as System Info/Profiler will only show the number of physical CPU cores.

There is usually an option in the BIOS to turn off Hyper-Threading if you so wish, but generally you should leave it on as in most instances Hyper-Threading allows the CPU to process more data concurrently.

Cheers
Jay

Mine I just can se the halve acting in the activity monitor, half of the procesor, the benchmarks are fine
