AMD Threadripper 3970X under heavy AVX2 load: Defective by design?
He&#x27;s not alone; I&#x27;ve had similar problems with my 3960X.<p>It seems to be a power delivery issue, and fortunately fixable if you disable all spread-spectrum and VRM power-saving options, but the Zen series seems a tricky beast.<p>I&#x27;ve had machine crashes triggered by using the &quot;wrong&quot; CPU scheduler under Linux. It&#x27;s amazing, in a horrible way.
