Just flashed this 450w bios, but not really any improvement. I can't get the card to use over 400w in any benchmark. All sliders maxed out. It doesnt seem to use the max voltage most of the time either. I know the mhz limit is around 2115, if it goes to/over 2130 it crashes. It does go over 1050mV (upto 1093mV) on rare occasions. But it usually hovers around 2055-2070 mhz @ 1012-1050mV @ 370-390watt or so. Any reason it is not using max power? Temps roughly 65°C. 3440x1440 resolution. Or any benchmarks / tips to make it use the full 450w? Flash is confirmed in GPU_Z, but I am not even sure everything is ok, as I have never seen it over 400w basically. Using MSI Afterburner with the voltage slider working.

 
I’m still having this exact same problem...gone so far as to nuke and reinstall windows fresh, have tried just about everything I can think of with the same results. At this point, I guess I just fall into the “we don’t guarantee increased performance” Jacob listed, maybe it’s why it’s labeled beta? I just wish there was some way to confirm my card can’t do more than 400w because of (x) reason even though my power target is 450w

same here, My crash number is 2145, I think a get peaks about 433w but its not close to pulling 450w ever. 

The quality of those cards and the conditions in which they are run do not require more power than thay are already drawing.

When undervolting, it becomes pretty clear that for each (lower) voltage you can set a max frequency before it crashes. I would think that for overclocking, if it would at least pull (close to) its max 1093mV more consistently, it might be stable a bit over 2130mhz (for my card). Hence, it seems to my layman's eye that it's not using its available increased power budget to push higher stable frequency. Am I wrong? (e.g: if I could force feed it more juice, it might be stable at higher frequency?)

I could accept this answer if I wasn’t sitting at 400w with power limit showing and clocks dropping sitting at 60c max core temp, I didn’t think that would be too warm? Regardless of that, I don’t really want to run the card full time over 400w, but I should be able to see it even briefly with my setup and I can’t, that’s what’s frustrating. Everything says I can hit 118% power target, but sits at 105% as if I never installed the higher power bios.

Open GPU-Z, got to advanced, select nvidia bios. Does it show a 450w maximum?
 
You need to understand that 450w bios doesn't mean the card will pull 450w, that's just what is available to the card. If the card isnt a great clocker then it wont need 450. I had a 3090 that was a poor clocker and it would clock any higher than needing 420w to hit its max. You could throw a 750w+ KP bios on the card and it still won't draw more power than it needs for clocks (and voltage) it can reach.

Yes, GPU-Z shows 450w under Nvidia bios. I understand there are many factors that go into how much power the card will draw - but the only limiter I’m hitting in Timespy is power, it happens at 400w and clocks/voltage drop because of that tho I’m stable. There is no clear answer for me why it won’t go past 400w, which is what I’m trying to find.

wrong thread, sorry X_X

I too am unable to break the 400W wall despite using the 450W bios. Not quite sure what to do, the card just refuses to use above 400W and gives pwr as the perfcap reason. Bios definitely shows the 450W maximum in GPU-Z, and I've updated both the OC and normal. Neither can do it.

Same here, not able to reach 401W... anyways I got a bad binning because my memory wont go higher than +600Mhz stable and it is a 3080 FTW3 ULTRA... meanwhile my friends 3080 amp holo reaches +1650 on memory ;_;
