No, you can't enable Threadripper's extra two dice
by from Techreport on (#32MBZ)
Gather 'round, gerbils, I've got a tale to tell. See, before AMD's Ryzen Threadripper released, notorious hardware destroyer der8auer ripped apart a chip and found what appeared to be four silicon dice under the lid. This interesting bit of info arrived shortly before AMD said that Threadripper made use of only two eight-core "Zeppelin" dice, and that the two extra bits of silicon were non-functional "dummies."
