Undervolting 3080/3090

[EggyRepublic]

I plan on buying a 3080 for 3D rendering, which means the card will be pretty much going peak power all day. I'm wondering if anyone have tried undervolting it to reduce power consumption, and what results you have gotten (or expected to get).

 

I've heard of other cards' power draw being reduced by 30% by sacrificing just 10% performance, and since Samsung 8nm isn't exactly that power efficient compared to the TSMC 7nm, I think undervolting might be a good idea (similar to what people did with the Vega 64).

 

Any general tips and warnings to undervolting a card would also be appreciated, thanks!

I haven't seen anything online yet about this but you'll see a bunch of it soon with the 3080 AIB capacitor design issues which are going on, should be decent undervolting potential given most cards are boosting way past 1900mhz on stock settings.
