Strange issue – GPU functions just in the lower PCIe lane (x4 slot) once the upgrade was done.
Strange issue – GPU functions just in the lower PCIe lane (x4 slot) once the upgrade was done.
Hi everyone, here’s a summary of your setup and troubleshooting steps:
Your system includes an Intel i5 10400 CPU, GTX 1060 GPU (3GB upgraded to RX 6600), 8GB RAM, and a Gigabyte Aorus B560M Elite PSU. You’re using MSI A550BN with 2x8GB Corsair Vengeance Pro RGB. Windows 11 is installed with BIOS v11.
You moved the GPU from the original PCIe slot to a second PCIe x4 slot, and everything works now. However, when you tried to install the GTX 1060 in the top PCIe slot, it didn’t boot properly—black screen, no VGA light, and the card wouldn’t recognize.
You’ve already done several fixes: CMOS reset, forced top slot to Gen 3, disabled auto driver installs, updated BIOS, and changed the PSU. The RX 6600 still shows a red VGA light in the top slot.
Some suggestions:
- Double-check the PCIe slot connections.
- Ensure the GPU is seated correctly in the new slot.
- Try a clean reinstall of the GPU drivers.
- If issues persist, consider using a different PCIe slot or consulting a professional.
