Question Sapphire Nitro+ RX 7900 XT RGB is not lighting up
Question Sapphire Nitro+ RX 7900 XT RGB is not lighting up
Hello everyone,
I own a Sapphire Nitro+ RX 7900 XT graphics card. After using the TriXX application, the RGB display stopped functioning. The card itself seems fine, only the RGB display is affected. I attempted a clean uninstall and reinstallation of the driver, as well as reformatting it, but it didn't resolve the issue. Anyone have any suggestions?
Which Trixx version are you using? Is your GPU connected to your motherboard's ARGB header? We'll need the motherboard model, BIOS details, and information about any lighting software installed. I attempted a clean uninstall, reinstallation, and formatting, but it didn't resolve the issue. Are you running DDU in Safe Mode?
So before you installed Trixx, the lights were working and the card wasn't tethered to the motherboard with an ARGB cable?
Give the second post suggested in this thread, a shot;

I've formatted the computer with a USB using Rufus and re-downloaded the drivers, but it's still the same.
Where did you source the installer for the OS? Did you install the OS in offline mode? Manually installing all necessary drivers while in offline mode?
When I stated using DDU, I meant running it in Safe Mode to remove all GPU drivers(intel, Nvidia and AMD) then manually installing the latest version sourced from AMD's support site in an elevated command, i.e, Right click installer>Run as Administrator?

include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.
You mentioned the DDU program, but I didn't use it because I completely reset my computer. I downloaded the Windows 11 Pro ISO file from the Windows website and connected to the internet during the installation. So, I didn't do an offline installation.
Since I'm connected to the internet, it probably downloaded the drivers itself. The long RGB portion of my Sapphirenitro+ RX7900XT graphics card still isn't lighting up. I've included a picture for you to understand better.

edit: i did not install the drivers manually.
I saved the Windows 11 Pro ISO file from the official site and connected to the internet while installing. This means I didn’t perform an offline setup. The issue is that the OS will automatically download and install drivers it believes are suitable for your system. Running the installation in offline mode would result in missing or incorrect driver installation.
I’ve attached a picture to help clarify the situation.
I’m familiar with what the light bar indicates. I also revisited an older thread about SignalRGB and wondered if that might affect the outcome.
PSU: DeepCool PF750
Not a very reliable power supply.
