2080ti Abominable performance

[Dragon2hand]

Hello,

 

I would like to preface this by stating the following information about my PC:

• 3900x @ 4.43
• 4x8gb 3600mhz Corsair ram
• Asus 2080ti Strix OC
• Corsair RMI 850
• Asus x570 crosshair viii hero
• All custom watercooled by EKWB

The problem is that my 2080ti started to under perform and display lots of unreliable voltage/power limit indications on MSI afterburner as well as HWinfo. Game stutter and FPS drops/jump have become part of my life again, I don't want to experience it anymore.

 

Here are my userbenchmark and 3dmark stats before it started going downhill:

As of late, here are the current benchmarks:

Safe and kinda-safe OC settings:

 

 

 

Things I have done:

1. Took apart GPU and reapplied thermal paste with good contact (was a problem previously, not this time)
2. Changed PSU cables and PCIE cables (Im using 2x8pin power connectors for my 2080ti)
3. I have set all the power/ temperature limit sliders to the max
4. Switching the physical bios switch on the GPU
5. Uninstalling GPU tweak and other overclocking software that may conflict
6. Clean install of windows 
7. Set Max performance settings in Nvidia control panel and made sure they saved (was a problem previously, not this time)
8. Tried fiddling with Single/Multi OCP
9. Tested default settings for the GPU (Still underperforming )

Misc information:

• My 2080ti currently maxes out at 64c (It used to max around 78c)
• power% graphs show it maxing out at 115% before normalizing at ~45%  (It used to max out and maintain ~110%)
• Voltage graphs show it also maxing out initially at 1.033 then normalizing at 0.817 V (This wasn't the case before i started having problems, the voltage and power would jump to 120% and normalize around ~100% and ~1.01V)
• This is also true when testing default clocks 

 

I have had a similar problem like this before and managed to regain (97-99%) performance back, but I unfortunately have lost whatever little patience I have left in me to figure it out.

 

If someone could guide me through this it would be much appreciated. 

 

PS, sorry if im lacking any info, I wrote this at 4AM...

Are you using 2 separate PCIe cables?

 

In other words not using a single cable from the PSU.

Yes, two separate PCIE power cables

GPU air cooled....?

 

It's really stepping down quickly....

Its watercooled with an EK 2080ti strix classic block.

Might want to check and see if the pump is actually working correctly....

 

Shouldn't be stepping down that fast.... And not that far down either..... Looks like it's going all the way down from your score....

My CPU temps would definitely throttle if that was the case, I have tested that when I first got my PC rebuilt. Between 350-750rpm my CPU would throttle and below that; the CPU would shut off. CPU temps are all good which means the pump is doing great.

There was a bug on the inicial cards not passing 1350mhz clock.

 

Try changing the bios to something else if its not under warraty . If it is I think you need to send it to RMA.

This wasn't a problem till now, I don't think its a Vbios problem and more of a physical problem, I might have a visual look at the pcb to see if anything had burnt up. It'll take me a few weeks to have a chance at seeing if i can pull it off tho...

I had/have a similar problem.

 

My EVGA FTW3 Ultras have a bug when using MSI Afterburner. It is triggered by another program in the system.

 What happens is the power limit gets stuck at around 61%.  

 

The bug can survive a reboot but goes away with switching the computer off.

Fortunately the program conficking with MSI Afterburner does not start up with my computer so this bug appears random.

 

To avoid the issue I stopped using MSI Afterburner to overclock and when I do us it to monitor I make sure that no other program is monitoring the system other than Windows. I also have the GPU startup stock and then add the overclock before I play or bench.

 

What I recommend is put the card in another computer and test.

@Dragon2hand I've got the same card and don't have the problems you mention. My overclock is considerably more aggressive than yours, an we are using the exact same drivers.

Alright bois, I dont know what i did. I managed to fix it and max out my scores:
