....................... with windows 10 and 11, I have a 14core processor........................ but it is only using 8 of the cores.
Windows probably doesn't need more that eight cores to run efficiently so what you're seeing is probably normal.
Try a program that's designed to use all available cores by rendering a complex project in Adobe Premiere Pro or 3ds Max and checking the number of cores in use. If you can't do that then, as far as I know, Cinebench has the option for a multi-core stress test.
Did you limit number of processors with msconfig/boot/advanced ?Windows is only seeing 8 / 16 cores , but the CPU is a 14/28 cores CPU

Number of processors check box should be unchecked.
Reboot is necessary after changing these settings.
Do you have the F6 BIOS (or newer) ? This page says it is required for your CPU -- https://www.gigabyte.com/Motherboard/X299-DESIGNARE-EX-rev-10/support#support-cpuNo, nether are ticked.
weirdly, if I do tick number of processors, there are only 16 in there an not the 28 there should be.

Could you have been ripped off? Did you buy the CPU new or was this PC a prebuilt ?The motherboard is using bios version f7e. again weirdly CPU-Z reports 8/16 cores and not 14/28
when I run a memtest86, it works perfectly with all cores.Could you have been ripped off? Did you buy the CPU new or was this PC a prebuilt ?
Where did you find this option? A good explanation for future folks looking for a solution would be great.OK, found the issue, if you disable intel wifi compatibility mode, its works again
