No, I would search for your motherboard model and forums to see what situations might match yours so that you might glean something useful as far as settings go. A quick check revealed nothing useful that stands out to me. Resetting all electrical connections was the lone useful tip. (The reddit link blocked me, lol. Fine) Perhaps more detailed (or different) search terms would produce better results.
I think you’ve taken the right steps to this point. Another CPU to test with would prove useful (though your original should suffice). Or another board to test this CPU in. Perhaps the shop you procured this one from has one or the other? Otherwise, I would pursue replacement.
All my sisters went into healthcare. The men all went into IT. I suppose the women care and the men are into constantly fixing things? IDK.
