Any risk to undervolting?

[ultima_trev]

Due to Hawaii/Grenada's ability to get to over 90 Centigrade, I have been undervolting and reducing the power limit as much as possible. So far I have it stable at -69 mv core / -31 mv aux and power limit set to -30 percent. It runs much cooler and quieter this way although the clocks throttle a bit (950 ish versus 1000), the performance impact is negligible however. Will sustained undervolting damage the hardware?

Nope. It's not like running an engine too lean, or something.

It won't. If any issues arise from it, it will reboot or freeze.

Or could potentially show artifacts/instability, but it will not damage the card.

Appreciate the feedback.

I now have it -81 mv on the core and still stable with power limit at -28 percent. Temps are down to (under load) 70-82 centigrade versus 88-95 and fan speeds down to 60-72 percent versus 90-100. There is some performance impact although it's not noticeable outside benchmark scores, generally <5 percent and Witcher 3 still runs 45+ frames at 1920*1200 Ultra in heavily populated areas.
