Is this a known problem?

Specs:
Skylake 6700K i7
Gigabyte GA-Z170N-WIFI, bios version: f7
Vengeance DDR4 2133mhz 2x8GB
Samsung 950Pro 256GB m.2 Nvme SSD

Very likely it is a UEFI BIOS bug.
There was new BIOS released for the this motherboard, version F7f, released a couple of weeks back. You might want to try that.

Thanks for the quick response, just tried with F7F and result is the same. Also tried disabeling HT, Memtest detected 4 cpus but the outcome was the same here as well.

As David mentioned, it is likely a UEFI BIOS bug that the vendor has yet to fix. So you may have to settle with running in single CPU mode.

If possible, can you upload a copy of the MemTest86.log under the EFI\BOOT\ directory of the USB drive as well.
