What does CPU-z say? if you have done all the right steps in BIOS to active all cores and still nothing shows up you may have a DOA processor here and you'll have to contact your seller for a replacement or in case the return period already ended RMA directly with Intel.

Check CPU-Z, though Task Manager should be able to recognize everything totally fine. Check your UEFI to make sure there are no weird settings in place. Run some benches(like Cinebench above), to see what performance is like.
