(This is a bit overwhelming) I am trying to find out what is the go-to benchmark for GPU performance unless I do need to spend $30 on Steam to use 3DMark's software but in the meantime, I am using SuperPosition by UNIENGINE so hopefully this is OK.

I am completely new to this so bare with me..downloaded Afterburner, dropped my Core Clock down -290MHz and then brought up my curve to 1950MHz @ .925mV as shown:
 



*** I forgot to click the MAX on Board Power Draw but I saw it hover around 335W. That GPU Hot sport temp kind of worries me, is that normal?

My fan curve is basically a straight line from 40% @ 45C to 100% @ 78C. The ambient temp in the room is 75F (24C).

I ran 4K Optimized in SuperPosition and here are my results:
 



When looking at other scores on the site, I feel like I'm a bit farther down the list...then again I see guys on the first couple pages who must be using liquid nitrogen and are truly overclocking...thats not really my goal here which is to maintain or loss <5% of performance while dropping a good 5+C in temps if possible. Can I please get some assistance and direction?


My PC Specs are as follows and everything is STOCK:
ASUS ROG Maximus XII Hero
10700K
3080FTW3 Ultra
2x140 NoctuaA14 intake
1x150 NoctuaA15 exhaust
Noctua U14S CPU cooler
 
 
Thank you!
 

Alright... so first of all if your goal is undervolting then don't bother looking at other people's scores to begin with. Your comparison should be to your stock scores, which you have not posted. Without that information its hard to know what is wrong, if anything. Post that and I will try to help you out with an assessment later (I am going to bed when I hit submit )
 
Second of all, I think you are a bit confused regarding the intent here. You're correct about the temperatures, but undervolting these cards does not "maintain or reduce" performance. You should not be looking for that. Performance will increase, this is the new age overclocking. My own current undervolt is 0.887V targeting 1950MHZ. When I run 4K Superposition using these settings, my clocks stay close to 1950MHZ the entire time. Occasional drops to 1935MHZ and that is it for the most part. When I run Superposition at the stock GPU settings, voltage will typically be around 0.962V with lots of variation. Temperatures will be higher and my clocks will be all over the place, dropping as low as sub-1800MHZ. The resulting benchmark score will be 750-1000 points less than my undervolt score.
 
That should be your goal when you undervolt. You pick a clock speed you want to target, and then find the minimum voltage to hold it there steady (a little fluctuation is fine especially in heavy benchmarking). This results in better temperatures yes, but also increased performance by not pumping unneeded voltage through the card and causing boost to scale your clocks back as a result.

I know the fan curve issue has been discussed between PX1 and AB. I opened PX1 and applied the chainlink at 65% for the fans (in AB it would show 75%, weird). This was applied to both benches. I have not touched the memory clock in my custom Profile..

Profile 1 was using the same curve as shown in OP. Was hoping for a larger score gap. This was the curve for the Stock profile which may be common knowledge at this point

Thanks for that! So when youre playing games your fans are at 100% or are you setting a fan curve? I've locked mine at 65% in PX1 for these benches...maybe I need to adjust. I am getting 375-380W Max Board Power Draw with all of these benches. This was my most recent bench of .912mV @ 2022MHz (have not touched the memory clock):
EDIT: the HOT SPOT section on GPUz shows 83C+...is this concerning???

I did the manual switch to the secondary OC bios and let it handle the fans on its own. I generally didnt bother with the fans because Im ok with the aggressive fan curve and I focused more on good intake case fans. Generally I don't feel a noise apart from air blowing which is absolutely normal.
 
Memory junction/hot spot of 83c is absolutely normal. Thermal throttle of junction starts at 110c.
 
Generally speaking even with temperatures up to 80c for the GPU you don't have any problem other than fan noise. In reality you would rarely hit 80c even with stock settings. However with undervolt you can keep the temperatures low and at the same time you don't reduce your power.
 
I have been running like this for a few months now the system stays very cool even after long gaming sessions and it takes 1-2 seconds to drop temp (again dependent on how good your intake/exhausts are).
 
P.S. Gaming at 1440p FULL ultra max RTX max all no compromises 165 fps where available.
Cyberpunk everything ultra at 85-100 fps with temp 62c max to give you an example.
Witcher 3 full ultra 165 fps 66c max.
Division 2 full ultra 120 fps 67c max
Forza Horizon full ultra 165 fps 60c max
No Mans Sky full ultra 120 fps 60c max
GTA V full ultra 100-140 fps 66c max
 
These are to give you an idea. No Mans Sky is the only game that is unstable at 0.850mv so I stabilize it at 0.875.
