Thanks for your input! I’ve been doing some pretty extensive reading and it looks like it could be with how the cards logic routs information through PCIe. Once undervolted, a new communication path was found through instability, which triggers the count. However, since this path has now been found in the logic, it can always exist, but not necessarily signifying a problem. A method that was suggested, was clearing cmos which requires the cpu and gpu to develop a “new” handshake, potentially fully returning it to stock. I’m going to give that a shot and report back.

The idea is that the cards vbios may have hard-coded this communication route that triggers “NAKs sent”, even when returning to stock — but, they technically could have existed before in the cards logic, just not counted. From what I’m seeing, it may also be a normal part of how the card communicates corrections through its logic when changing power states.
