Wait... not 1.288, but just 2.88? That's the oddest thing I've ever seen.
Seems like dead sensors or faulty software. What's it say when you go into your BIOS?
0.288 is what it reads on the bios overview page and in CPU Z. The only place it doesn't read that is the spot in the Bios where I manually enter the Vcore I want (1.21).
