Hey do you think it's worth taking apart my Xc3 3080 ti hybrid and replace the thermal pads and thermal paste to more of a premium ones to get better thermals?

Has anyone try to undervolt their 3080Ti card below 812mV and core memory below 1093.75mhz or 17.5Gbps memory bandwidth? I've eVGA 3070Ti but would be good to know if 3080Ti behaves the same too. I'm using both MSI AB 4.6.4 beta 3 and Precision X1 and I'm unable to get both to work. I'm not gaming or mining but running distributed computing (maybe quite close to mining) projects and trying to figure out the efficiency curve. Thanks in advance. 
 
P.S. I know there is a min limit and I think it should be able to go lower. Maybe this is defined in nvidia P-states or perhaps there is a way to tweak via nvidia-smi tool?

Undervolt to get virtually the same performance and reduce your cooling bill

gpu temps only tell half the story
games utilizing the entire gpu(rtx and dlss) most certainly can and will max out the power limit,even with a custom voltage curve
If the vram is not sufficiently cooled (low fan speed,poor air flow) it will overheat without you even realizing it.
 

Can't stress the enough.  Put my 1300w Seasonic Prime into protect shutdown while locking 1V and 2,040 mhz on a DX11 game in 4K VRR at ~425w.  Some of these newer games with poor optimization (like New World) can easily produce a full power load at .9V vcore, or even less.  So if can't cool your card properly, set your power limit to actually restrict temps, not undervolt.

I've a feeling "The Ascent", a new game from a small Swedish studio, is a similar story. The game runs like an absolute dog on DX12 with Ray Tracing on, and my 3090 acts weird. GPU utilisation all over the place, framerates and frametimes all over the place, a creaky sort of coil whine that I never normally hear. The temps themselves look absolutely fine (58C GPU, 82C memory junction), but I've stopped playing until they release some patches because I can tell my system is having a horrible time trying to run it

What’s funny is that an undervolt actually exposes how poor it runs stock. With 70 watts less power consumption, a lot less heat and fan speed requirement your Timespy graphics score will actually increase. More horsepower on less fuel!

What these high power cards expose is how poorly most people's PCs are set up for cooling.

Its kinda hard to do a balance of a good overclock with undervolting. Its one of those fine tuning things to find exactly where your card is most stable where performance is increased while also trying to get better overall temps. 

The balancing act is tedious, but for me its quite fun. 

Currently got a somewhat stable .943mv at 2010Mhz, with +1150Mem through AB, but I'm experiencing some minor issues with random frame drops or slo-mo just with something like youtube or twitch every now and then - whether multi-tasking a game on main monitor and watching video on 2nd monitor or not. This may actually be due to using multi-display power saver from Inspector as I previously had an issue with my 980Ti GPU not throttling down when there is no load. And after getting the 3080Ti and putting it on water, i kept using multi-display power saver. I've since disabled MDPS but have yet to do any more testing or have the curve applied as I havent been in the mood for gaming. 

I should have had MDPS disabled in the first place when getting the 3080Ti as the "full clock" behavior that I had with the 980Ti using multiple monitors doesn't plague me with this card. 

At least while on that curve while gaming at the time, it would go up to 2050/2100Mhz and temps would stay at a rock solid 54c playing Metro Exodus Enhanced at 1440p. 

Dedicating one more weekend to troubleshooting this odd slo-mo issue with my normal gaming habits this weekend should do the trick. And then I can continue playing with the voltages a little more as the days and weeks continue when I have the time, tweaking little by little and testing each change. I like seeing a nice smooth transition but so far this is where I'm currently at. Then..... I'll start overclocking the 9900k

So is decreasing power limit to 80% the best way to solve instability issues with an undervolt?

I've tried tons of different voltage frequency combinations on my 3080 Ti FTW and always think things are stable, until I find a new game they crash in. Originally I tried 1929@900, then 1875@900, then 1845@875, and still no luck.

Most solid was the latter, and it held with optimal results (-8c, -2-4fps, -80-100w) in tens of hours of testing Apex Legends Maxed, but now I'm trying Doom Eternal maxed out with RT and DLSS and the game is crashing every little while, even when clocked down to 1830@875.

Would I be better off just power limiting the card to control power use and temps? Where should I start, 80%? Any other changes I should make?

i put 50 hours in new world on my 3080ti ftw3 ultra at 875mv at 1900mhz. barely noticed any fps difference. yet my temp went from 80c to 70c.
