Yep, windows and cpu-z are having a problem.

It may be that your motherboard needs a new bios.

This kind of problem is almost always the result of a bad BIOS. The fact that the BIOS may, in its Setup screens, report the right information does not guarantee that they do not have bug(s) in their initialization or O/S-reporting code. If nothing else, you need to be talking to Asus and having their BIOS engineers look into this.

 

That said, I am bothered by the fact that Intel's IPDT is not reporting this properly. I would expect that this tool uses the CPUID and RDMSR instructions to properly identify the processor, not just what is reported by the Windows O/S. While it's true that the tool can only run its tests on the cores and threads that are exposed within Windows, I would have expected the tool to report this discrepancy. Is there anything to this effect within the LOG file? Please upload it. Intel Customer Support needs to look into this aspect of the issue as well.

Thanks for uploading. Unfortunately, the log says nothing about supported cores/threads. Intel Customer Support needs to look into this aspect of the issue as well.

i think if i reinstall windows this issue will solve, might be a problem on register of windows that do not dected all, that's why cpuZ dont see rest of them...

The processor is validated and warranted for DDR4-2666, which means everything from DDR4-2133 to DDR4-2666 is fully validated. You are using DDR4-3000, which is a mild (XMP-based) overclock of the memory bus and has not necessarily been validated (nor is warranted to work). But, provided everything is working ok, I wouldn't replace this memory.
