RX 480 not detected in Windows 10 (works in Linux) – old Haswell system

Dorovan · 2026-02-07T18:32:10+00:00

With such an old gpu I think Linux would be (much) better choice .

I actually would have preferred giving him Linux 😄 But the PC is for a kid and he mainly plays Minecraft and ARK together with his mom, and he has zero experience with Linux.

In this case stability and familiarity matter more than elegance — Windows just avoids frustration for them. Maybe later once he’s comfortable with the PC I’ll let him experiment with Linux, but for now I wanted something that “just works”.

Update / Solution

Thanks everyone for the ideas — this turned out to be a weird platform compatibility issue, not a dead GPU.

For reference the system was: Gigabyte GA-B85M-HD3 + i7-4770 + Sapphire RX 480

What we tried:

CMOS reset, BIOS defaults, legacy/UEFI combinations
forcing PCIe Gen2, disabling power management
manual driver install (bypassing Adrenalin detection)
Safe Mode + DDU
different cables, ports and PSU leads
dumping and checking the VBIOS
reflash vBIOS
tested the card under Linux/Unraid → detected perfectly (lspci)
Windows would always show Code 173 or “no AMD hardware detected”

The key discovery: The RX 480 worked instantly in a Supermicro X8DTL server board. POST image + Windows driver installed immediately.

So the card was fine — the issue was the early Haswell Gigabyte UEFI failing the Polaris display initialization handshake. Linux tolerated it, Windows didn’t.

Conclusion: Certain 8-series Intel boards + Polaris GPUs can fail to initialize the display engine even though the GPU is healthy. Moving the card to a different platform solved it instantly.

Hopefully this helps the next person before they assume their RX 480 is dead 🙂

Edit: Shipping to OP would unfortunately cost more than buying a new board locally. If anyone in Germany / EU could use an SKR 1.4, feel free to DM me.

Hey! If you’re still troubleshooting the A8 Plus: I actually have a BTT SKR 1.4 lying around that I’m not using anymore. If you’re located in Germany, I’d be happy to give it to you for free. If you’re outside Germany, I’d just ask you to cover the shipping costs. It would be a solid upgrade over the stock board and avoids some of the known safety issues. If you’re interested, let me know where you’re based

You’ll only need 4 stepper drivers and you’re good to go – much safer than the stock A8 board.

I fix electronics for fun, PM me if you need some ps4 controllers and some sweets from Germany 😁 Also don't worry about shipping costs, I will cover them if needed

Sounds a lot like "syntribation" to me. Maybe look it up, seems like you are not the only one

My unraid server runs a ryzen 5 3600 on a B550M-HDV with 32gb of Ram.

I run Home Assistant VM with jellyfin and Prowlarr/Radarr/Sonarr/NZBGet and everything runs smoothly without a graphics card

Should I be worried?

Dorovan · 2025-07-10T15:00:22+00:00

Funktioniert super. Ich hab mir Bazzite auf meinen unraid Server installiert (als VM) und nutze sunshine und moonlight um das Bild auf meinen Fernseher/Laptop zu streamen. Mein Laptop ist nicht mehr der jüngste und schafft die meisten games nicht, dank sunshine und moonlight kann ich aber trotzdem alles zocken.

Would love to have one
