As title says, my card is unstable and throwing nvidia display driver has crashed in windows event log on stock (untouched) voltage with power target set to 120% during some fps games like Overwatch and Lawbreakers. Sometimes complete freeze, other times driver recovers after black screen. Temps get to about 78C (hot ambient room temps) with latest WHQL driver and GSYNC on. Question is my card defective or do I need to up the voltage in precision to run it stable at 120%. It is boosting to about 1979mhz stock and memory stock. Every other component is stable and tested. Thanks for the help. Edit: Even unstable with power target at 105% and higher as explained later in this thread. Has been becoming less and less stable at stock power target too.

Just to double check, are you only sliding the power target to 120% or are you OC'ing the memory or GPU clock?

Just the power target slider to 120% and temperature is linked so it goes to 90C. My card defective?

I don't know if I should say it is "defective" if it is stable without increasing the power target but personally.. I would RMA a card that is unstable when only increasing the power target.

Try turning off Gsync to see if that's affecting it?

I will try with that but I would prefer Gsync on. It seems stable at stock clocks and stock 100% power target with Gsync on. Edit: Tried turning off gsync putting power target to 120% and overclocking memory by 50mhz. Immediately within 5 minutes had green artifacts all over screen in game. Do you think something might be wrong with my PSU, it is an EVGA supernova 1050W Gold. No issues after 1 hour gaming on stock power target and clocks for about an hour though. Maybe my SC Black needs more voltage at 120%.

Are you using a single pci-e power cable to power the card or two separate cables to power it?

2 separate power cables from psu's vga labeled slots to the card. PSU is evga supernova 1050gs. Which is optimal, 1 or 2 cables?

2 cables is the best option. At completely stock settings it's boosting to 1979 mhz? What does the card try to boost to at 120%?

At absolute stock 100% power target, it boosts to 1962mhz core at its highest. Does not spend much time there though, spends most of its time in the low 1800s high 1700smhz.

Down clock both the memory and core clocks by 200mhz and test for stability. If reducing the clocks eliminates or reduced the crashing, the GPU is defective.

I wonder if defect lies in that my card is overdoing power target. I see max on HWMonitor that it is hitting 125% at times. SC black is capped at 120%. I still have not gotten it to crash at power target 100%. Think its worth testing at maybe 110% or 115% power target? At 110% power target, 90C temp slider, +0 core +0 mem I got crash which looks like this. https://ibb.co/g2stBa Very disappointing that I will have to RMA a card just over 30 days old it looks like. The card is defective?

125%? Maybe you're having Energy Spikes when in max Power Target? Try checking if your 12v / 5v / 3.3v rails are running ok (+/- 5% margin of variance). This might cause artifacts at you GPU as well, as black screen and hard resets.

Power Target hovers around 100% what I have it set to in precision but I see spikes in HWMonitor up to 107% momentarily during intense games. Interestingly, at 100% power target I can reliably OC memory quite a bit have tested for 2 hours of gaming up to +250mhz and no crashes but when I set my power target even at 110% I crash pretty fast in intense games. Still cannot figure out what is wrong with card, but I do not get any crashes at 100% power target. My power rails are running right on target.

I think there's sth wrong with your card's vrm...I had the same problem with my 1080 FTW in last September, mine was worse because once the power reached 100% the screen turned black (although I can still hear sound in the background). It turned out that the VRM was out of specs, had to RMA the card (was a pita because I had to tear my loop down).

Here is what I would try before sending it in for rma... #1 Try a different set of pci-e power cables. Make sure to use a different set of sockets (where the pci-e cables plug into the psu) too. #2 Try the card in a different pci-e slot. #3 Contact evga tech support, and have them help you reflash the vbios on the card. #4 Test the card in another computer.

I have tried new set of cables from PSU to card in different slots on the modular psu. Have not tried other pci-e slot it is 8x not sure if that will make difference. I can try calling EVGA about bios reflash later today. Unfortunately do not have another computer nearby to test in.

I tried upping voltage slider to 100% and setting powertarget to 110%, on stock core and memory and still crashed.

Sorry to hear that. Testing the card at a local computer repair shop is always an option.

Look at how low my voltage is at almost 100% load. Why is that the case? This is always the case with my card. Over the last month of using my card, it initially started out stable but has become more and more unstable over time. http://imgur.com/a/n958M

The vbios on the card may have some values set incorrectly. Did you reflash the gpu yet?

I am going to proceed with RMA. Anyone else with a Ti SC Black what hardware revision do you have? Also do you think EVGA precision xoc flashed something to my card which ruined the vbios? Edit: tried in my other PCI-E 8x slot and same issue is occurring. The card is also getting less and less stable even at all stock settings where it was fine before as I keep getting nvidia driver crashes more and more often. Why does it seem to be degrading more and more?

Tried a full reformat just to remove any possibility of it being software related, but still getting immediate artifacting and crashes at 120% power target. Any way for me to have an indication that it is my EVGA supernova 1050watt PSU failing? The 12v 3.3v and 5v rail readings look fine via motherboard BIOS.

Don't think it's your psu, but if you want to make sure it isn't your psu you could swap in a different psu.

So I usually crash in a game, at stock power target and settings, like Overwatch or Lawbreakers when the GPU load has dropped such as when a round has JUST ended and it is going to the menu not during the intense load of actually playing the round. Any idea if this can help diagnose?

What MB, CPU & RAM ? What OS ? Is your CPU or RAM (XMP) OC ? What happens with your MB/ CPU /RAM at stock settings ?
