1) We'll fix the CPU VDD and CPU Core voltage measurement issues in the next AIDA64 beta update.
2) I don't think your motherboard is capable of measuring VDDQ voltage. I cannot see it listed in ASRock's own utility.
3) There's some weird anomaly about MOS temperature measurement. As you can see, HWiNFO has the same issue about measuring it as AIDA64. Truth be told, AIDA64 shows it as South Bridge temperature
4) We'll check the rest of the issues you've mentioned.
