5080 Undervolt/ Overclock thread: How low can you go?...

(Posted this in the big thread but I think it deserves its own post. Mods slap me down if you must....)

I'm beating Jufes with my current work in progress undervolt/ overclock on my 5080 (MSI Gaming Trio). Got a graphics score of 35,140 in TIMESPY with a core voltage of only 0.97. Max power draw about 350w....

With my less aggressive core volts of only 0.94 and max power draw of about 315w I'm pretty much matching....

And, with only 0.91v(!) and max power draw of ~295w, getting 34,109....

For ref in his vid he was doing a quick and dirty sliders only overclock in Afterburner but he was maxing out power to 375w and presumably volts were at 1.02 at least. Really quite impressed with these 5080s you know, especially the undervolting.

What core speed do you set your curve to, with those volts? I personally think it's pointless to try the highest level OC with curve. I get similar 35100+ just with setting core/mem OC and 365W, not worth messing around for 15-20W gain, especially that I had instabilities even if I set it to 1V (for some reason AB was showing 0.96V during test, not sure if there is some sort of offset).

I might play with some lower curves just to see the difference.

Lovely stuff. I'll join in when mine turns up, I always ran my 3090ti undervolted as it was such a power hog otherwise.
