3080ti only using around 200 watts

[Optiks]

well the title says it all

i have bought a 3080ti and i only had problems with it till now

the card sometimes draws around 400 watts when running a benchmark and sometimes only 200 watts

this low wattage can sometimes be fixed by restarting windows but it doesn't work all the time

i already reinstalled a clean windows version, the switch on the card is on P Mode and i have selected "prefer maximum performance" in nvidia settings

the psu is completly new and has 1000w (i know a bit overkill)

is this just an error i did and can fix or is something wrong with the card (the transistor noise is extremly loud when it will only draw around 200 watts on 100% gpu usage)

 

sry for my bad english and thanks in advance

Just a thought; 

Does your 3080 Ti have power LEDs near the 8pin power connectors? Maybe they light up, when the wattage drops to 200 watts. Could indicate a power delivery problem.

No nothing appears. I'm using three independent 8 pin connectors. As I said sometimes a windows restart fixes the problem. Not sure why 

edit: i think my pci-e riser is the problem. On the website it says it can handle pci-e 4.0 but after some searching i have found ppl saying it can not and the gpu-z shows only 30 watts supply over the pci slot. Ordered a different one. Maybe that is the fix

Look at is the power % used. It is a graph on MSI Afterburner. 

On my EVGA FTW3 2080 tis it got stuck at 61% and it was caused by MSI Afterburner conflicting with other monitoring software. It basically froze the bios.

 

Another thing to monitor is PCie slot power and 8 pin power through GPUZ. 

I use Heaven in a window for this.

I have had bad PCie cables and 24 pin cables with new PSUs and it may show up on the readout.

 

Another thing to do is wiggle the cables. That is how I found a bad 24 pin cable that was only effecting the GPU.  

[Optiks]

this is the msi afterburner graph for the power % used during the benchmark

i'll try the Heaven variant to find out if there is a bad 8 pin

edit: i have a spare PSU so maybe i will try this one too

[Optiks]

no changes still the same problem

TDP  is around 61% but fluctuating between 50% and 68% 

i'm still hoping it is just the pci-e cable which is bad and after the search it is falsly advertised, only working with pci-e 3.0, despite gpu-z showing 4.0 capability

i'm a little nervous bc gpu-z shows only 80w drawn by the 8pin connectors

Here is what my FTW3 Ultra 3080 ti looks like at 400 watts.

That is what I'm aiming for. Do you get a perfcapreason? Mine says Vrel which indicates a voltage reliability and VOp

That depends on the application, what card you have and your power setting.

Running Heaven at 1080p stock my FTW3 Ultra shows PWR. If I raise the power limit it shows VRel. If I add +120 I am switching between PWR, VRel and Vop. With = +150 I am back tp PWR.

Time Spy stays at PWR stock, +100, +120 and +150.

Thank you for now 

I'm praying it has nothing to do with a damaged/faulty GPU and I hope the new riser cable will "fix" this. Under time spy stress test the whole wattage goes up to 360 with a tdp of 85% 

But gaming or anything else is a stuttering mess rn (without gsync) despite over 100fps on a 100hz monitor. As soon as I restart there is something else wrong again and the fps drops to 30 in games or to 50. Feels like a poker game Everytime

Have you tried without the riser?

 

The 30 series stutters more than the 10 or the 20 series did. Really good VRR is a must.  

Also any time I want to emulate stutter all I have to do is set Windows power saver.  

[Optiks]

using the amd high performance mode 

can't do it without the riser cable, my case is way to smol

[Slizzo]

PCI-E risers have been found to be at issue on AMD boards that support PCI-E 4.0.

 

Lock PCI-E at 3.0 on all your expansion slots in your BIOS. Should make things work better.

i will try that, thank you. I have a ASUS ROG STRIX X570-F GAMING with a 3950x

i'm not entirly sure but i think as soon as the card really draws power it crashes and activates safemode

edit: i forced pcie 3.0 and i have never had so much fps and smoothness
