So, an update since i know you guys could barely sleep without knowing what happened.
Short of it, at all stock, the card was pinned to 300w (according to MSI AB). This appears to be some kind of limit, because card would be throttling to about ~1530mhz.
Playing around in AB, with 50% power limit, I set -50mV which seems to have taken it down to about ~280w and boosted clocks to ~1580mhz. I'll play around stonet more tomorrow.
I don't see any option in AB to undervolt memory though and that is hotter than the core!
