Hi everyone,
I wanted to share my experience with an issue I encountered on my new build featuring the RX 7800 XT, in case others face something similar. Below is a summary of the problem, symptoms, and how I resolved it.
The Problem:
I started noticing unusual behavior with my RX 7800 XT after about 10 days of use. While running a relatively simple scene in Unreal Engine 5, my system crashed unexpectedly. After rebooting, I experienced the following symptoms:
Symptoms:
- Green tint in BIOS since day one:
- The green tint was present in the BIOS from the start, but I didn’t think much of it since it disappeared once I booted into Windows.
- After the crash, the green tint persisted even in Windows.
- One HDMI port worked but displayed the green tint.
- The DisplayPort (DP) port was completely non-functional.
- Other displays and cables worked fine with my old GPU, ruling out external issues.
Troubleshooting Steps:
- I swapped out the PCIe power cables for two new, separate cables to rule out power delivery issues (using a Corsair RMX 1000W PSU). (I didn't know about the rule of no daisy chain PCIE to supply hungry cards)
- I reinstalled GPU drivers and updated the BIOS, but the issue persisted.
- I inspected the GPU closely and noticed a connector near the PCIe slot under the heat sink was not fully seated.
- I carefully pushed the connector fully into place and reinstalled the GPU.
The Resolution:
After reseating the connector:
- The green tint disappeared immediately, including in the BIOS.
- Both HDMI and DisplayPort ports started working as expected.
- My system has been stable since, and the GPU runs perfectly under load.
Takeaway:
If you're facing similar symptoms (green tint, missing GPU features, or non-functional ports), inspect the GPU closely for any loose internal connectors or components. In my case, reseating the connector resolved all issues, saving me from a warranty return.
I hope this helps anyone encountering similar problems.
