troubleshooting Faulty GPU?

Imitheos · January 30, 2020

Greetings,

I recently won an eBay auction for a EVGA GTX 980Ti Hybrid for only $150 after shipping and tax. The reason for the low price, I would assume, is because the on-board fan connector is broken, requiring me to connect it to a PWM header on my motherboard. This seems to cause no issue, the card stays at 27c Idle, and below 60c under load. The first thing I did when I hooked it up was start playing with the clocks. I got to +165 Core and +350 Memory before userbenchmark runs started freezing, so I downclocked to 160 and 300 respectively, as this seemed to report the highest performance. The problem is, running games at these settings causes them to freeze and crash after only a few minutes. I decided to run a few other benchmarks to see if I could pin point the issue. When the core is overclocked at all I see a few artifacts in MSI Kombuster (Fur Mark donut,) which isn't immediately alarming. Factory settings in the physx test, however, results in way more artifacts than I've ever seen reported by this program:

Does anyone have any insight? Is there a way to fix this, or should I just return the card? Here is my system:

980 Ti Hybrid (Previously RX 570 Strix)

Asus Z87 board

Core i5-4670K

24GB assorted ram

Windows 10

(I did uninstall the readeon drivers and software before downloading Nvidea drivers)

Thanks for any help.

You overclocked your card, you get artifacts and you want to return card because of that?

No, it's not work like that. There is no manufacturer that can give you money back because you can't overclock as much as you can. It's like car engine - you can tune it up, remove muffler, put some modified extreme petrol in it to increase maximum speed, but you do it on your own risk. Do not complain that economy city car can't reach 250 km/h.

And really - how many more FPS do you get by that overclocking? 2? 3?

Um. 1 trillion artifacts measured in less than a couple minutes at factory settings should be more than enough reason to return it. Did you read incorrectly? The inability to overclock is far from the issue here.
