How to fix disabled AMD Ryzen processor cores

Ryzen 7

PCs are funny old beasts, and in the process of setting up my new Ryzen vii 2700X build I encountered a few ... hiccups. 1 of the more than troublesome ones was the PC reporting that four of the 8 cores were disabled, which I verified in several places and ran some benchmarks just to exist sure.

I searched the web, trying anything and everything, including resetting the CMOS (aka the small-scale onboard memory) on the motherboard by removing the bombardment and reflashing the BIOS. Naught worked. Merely somewhen I plant a very unproblematic thing did. All you need is AMD Ryzen Primary.

Update: As folks have been request in the comments, the set of events that triggered it in this example was applying XMP profiles and manual speed increases to the organisation'southward RAM in the BIOS. The issue is (in my instance anyhow) in no way linked to Windows 10 or the Ryzen Primary application, which wasn't used for annihilation merely the steps below.
