Investigate issues with AMD 6900XT experiencing frequent crashes or black screens after nine months of use.
Investigate issues with AMD 6900XT experiencing frequent crashes or black screens after nine months of use.
Every time I launch a game, my graphics card software crashes completely, turning the whole screen black and preventing recovery. I’m forced to restart the machine, then open Device Manager to turn the GPU back on. The problem repeats consistently—either the same failure occurs or I get stuck in an endless loop. I’ve tested the newest Radeon drivers, switched to older versions, used professional settings, and even reinstalled chipset firmware. RAM checks passed, and no logs provide any helpful clues. I’ve changed everything, tried disabling MPO mode, and examined the Radeon developer tools for analysis, but nothing makes sense. The crashes keep happening repeatedly, lasting over six months now. They sometimes disappear briefly before returning. I’ve reset my system several times and even wiped my Windows installation on both Windows 10 and 11, yet the issue persists. It isn’t limited to one program or game; it appears across various titles and even while browsing in browsers. I’ve found articles mentioning similar problems, but nothing useful. It might suggest a hidden hardware fault, though I remain skeptical. I run stress tests and benchmarks from tools like 3D Mark and Furmark, and no faults are detected. Performance metrics look normal—stable clocks, no artifacts, no crashes during long tests. Despite these checks, I still face this persistent problem. At the moment, it’s just a frustrating bottleneck with no clear solution. If you need any files to assist further, feel free to share and I’ll do my best. My current setup includes: OS – Windows 10 Home 64-bit; GPU – PowerColor Radeon RX6900XT; RAM – G.Skill Flare X5 32GB; CPU – Ryzen 9 7900X; PSU – Corsair RM850X; Display – Asus VG32VQ1B and Dell SE2222H.
I don't connect cables directly, but I can help you figure it out. Typically, you'd use separate 8-pin PSU cables for each power source. Some setups might combine them into a single cable, while others prefer two for better reliability. Custom cables or extensions are possible depending on your needs.
I connected the cable that came with my power supply, which features two 8-pin connectors at the end for the graphics card. I don’t have any custom cables and avoid using extension cables; everything is standard.
Use the second cable from the PSU box. Both cables are PCI-E 8-pin and separate. This should probably fix the problem.
Make sure you have two separate cables for your GPU power instead of using just one. Or, if needed, consider swapping out the current cable.
After three days of use, the problem vanished once you connected a second cable. It wasn’t by chance—it makes sense now. I thought the dual 8-pin cable would handle the power, but it didn’t. This issue seems resolved; I never considered trying that before. Thanks for your help!
