How to Identify My GPU When CPU-Z and Physical Labels Disagree?

[Andriy Andrusyk]

I recently bought a used GPU that was advertised as an MSI GeForce GTX 1080 Ti. The backplate label also identifies it as a GTX 1080 Ti, and the label looks untampered.
However, when I run CPU-Z, it detects the GPU as a Radeon RX 480.
I inspected the PCB and found a second label near the gold connector reading: V341 VER:1.1 From what I've found online, V341 PCBs are typically used for Radeon RX 480, while GTX 1080 Ti cards usually use a V360 PCB.
Is it possible the card was BIOS-modded or relabeled? What's the most reliable way to verify the actual GPU model I have?

Also the power connector, the GTX 1080Ti uses 1 8-pin connector and 1 6-pin power connector, or 2 8-pin power connectors from the power supply (depending on manufacturer), while the RX 480 uses either a 6-pin or 8-pin power connector (depending on manufacturer)
If you mod the vBIOS on an AMD card you also need to install patched AMD drivers, as the drivers wouldn't load on a modded vBIOS (back in the day when the RX470/480/570/580 were used for crypto mining some people used modded vBIOS with tighter RAM timings to get better hashrate)

You can post a screenshot of GPU-Z to check

I only see 1 power supply connector on your card

The "warranty sticker" at one of the screws, those stickers are sold at aliexpress, i doubt a GPU released 8 years ago hasn't been opened to change thermal paste

Picture of the MSI GTX 1080Ti Gaming X, spot the differences at the power connectors, also it has 2 SLI connectors near the rear bracket, also notice the GEFORCE GTX branding
Google "msi gtx 1080ti gaming x review" to get more pictures of the card




Looks like the seller made a new label, if you bought locally i'd get a refund as "not as described"

It's an RX 480. If you want to be sure you can take the HSF off and look at the core markings. And also the driver it's running. (Plus it's easy to relabel two near-identical looking GPUs... but you can't exactly mod a BIOS from AMD to Nvidia).

I am guessing you bought this from AliExpress or similar? The RX 480 is significantly less powerful than the GTX 1080 Ti so more than likely you have been hit with a relabelling scam.

You're right — it turns out to be a case of fraud. I was sold an MSI Radeon RX 480 instead of the advertised MSI GeForce GTX 1080 Ti. After comparing with pictures of genuine cards, the evidence is clear. The seller has disappeared into thin air. Thank you!
