This is what I have so far. Vcore doesn't match reality though and I'm not sure why, since it should be in range of the ADC (so scaling shouldn't be required), if I'm understanding things correctly. sensors says 0.90V, BIOS reports 1.05V, and i7z says 1.15V. Which is correct?
Also, BIOS reports DRAM voltage, but I'm not seeing any value here that could be that, without scaling. Am I missing something?
