Hey everyone,
I'm having a strange issue where the card will completely crash my system when i have two displays plugged in. My card is a Gigabyte 7800 XT GAMING OC 16GB. My main display is a 1080p 144hz monitor plugged through DisplayPort, and my secondary display is a 1080p 60hz monitor plugged through an HDMI connector. The crash happens when running games, at random times, and does not appear while stress testing; the main screen goes black, the secondary HDMI screen goes green for a few seconds, and the whole system reboots.
After speaking to several users online, i'm not the only one with this specific problem, as several users with this same monitor setup have the exact same issue. I am positive that the problem is the GPU, as i'm using a system that was completely stable for months otherwise before installing this GPU, and the problem disappears when i replace the 7800 XT with a GTX 1070.
Fixes i have tried:
- Changing my power supply to rule out power issues
- Disabling XMP
- Doing a clean driver reinstall several times, using DDU in safe mode and replacing the driver by both the 23.9.1 versions and the 23.9.3 versions, in full, minimal, or driver only installs (the crash persists in all of these scenarios)
- Disabling MPO
- Doing a complete clean reinstall of Windows
- Plugging the secondary monitor through an HDMI-DP adaptor
- Updating my motherboard BIOS to the latest version
- Plugging both monitors into the card in different ports (i tried all possible combinations)
None of these measures helped stop the crashes. The only thing that has actually worked to stop the crashes is using only my main DisplayPort monitor, that is to say, unplugging the HDMI monitor.
I'm looking to see if there are any other users here who are experiencing this issue, see if there is anything else i haven't thought of trying, and to maybe find out if this is a known issue that can be fixed by a driver update, or if i should return the card.
