With all the crazy re: BIOS at the end of this discussion here, I’m certainly not going to insert myself!:
For what it’s worth my MoBo brand hasn’t released a new BIOS version for AGESA 1.0.0.7.a., yet. They did release an update to address the EXPO voltage issue, so I’ve updated to that, even though my EXPO voltages were never in the at-risk range.
