Graphics Card Power Issue?

[KingKyah]

PC Specs:

• Evga Black 2080ti
• Ryzen 9 3900
• 2x16gb trident z neo 3600 mhz cl 16 ram
• corsair rx 1000 power supply w/ cable mod custom cables

So I've had this card for probably about a year now and it was running completely fine. I had an overclock on it with the power target set to max about 100 mhz on the core and 500 on the memory, but then it started to give me a black screen with all my fans ramping up and my system completely locked until I hit the psychical power switch. This probably went on for a week on and off until I completely reset the oc and now if i set my power target over 90% ill get the black screen in a few minutes. I've tried memory speeds and timings, set cpu to defaults, reseated my gpu and dduing and reinstalling the driver along with bios updates and chipset drivers, and the only thing I got to work was setting the power target to 90% or lower. It happens in games from Rainbow six siege, csgo ,oblivon, 3dmark, everything I tried to make it crash on it would. Any suggestions or recommendations to anything is greatly appreciated!

What are the temps?

The driver should have crashed in that case in order to protect the GPU,if it didn't then bye bye GPU!

 

You can try testing the GPU with GPUPI 3.3.3,Press Calculate then use the following settings:

32B HWbot GPU

choose your GPU in OpenCL GPU devices

Batch size: 20M

Reduction size: 512

Then press OK to start.

(Press cancel if a message about HPET appears)

 

Tell us if you get any errors while testing.

This is what I got after running it at a 87% power limit the only thing that happened was it told me I had a timing issue and it had to change it for me before I could start other than that i didn't get any errors so I'm going to try again at 100% power and see what happens, and my temps usually stay around the mid 70s (itx case I know that's not the greatest temps) Ps. When I tried it at 100% I got the same black screen thing that's been happening.

You did the wrong thing:

You need to disable it,since it can cause weird issues - including performance issues.

I turned it off and I got the same result. Did it just fine at lower power target but then black screened when i put it up to 100%

It indeed sounds like a power issue.

[KingKyah]

would it be more like a power supply issue or graphics card?

I don't know.

I would find what exact size thermal pads you need for each section of the card (may need different thicknesses depending on if VRAM, VRM's, chokes/spacers, etc, or front or backside), and consider replacing the thermal pads and repasting the GPU Core.  I would do this before tossing money around on PSU's.  Some cards simply have the pads degrade and overheat without any way to monitor anything but the GPU Core temp itself.
