GPUVerified

For people buying and selling used graphics cards

Show the card's condition. Prove it's the same card.

GPUVerified is like a vehicle history report for a used graphics card. The seller runs a 10-minute test and gets a signed certificate with an A–F grade, a public page and a QR code for their listing. When the card arrives, the buyer runs a 2-minute check that confirms it's the card that was tested.

Works with NVIDIA GeForce cards on Windows and Linux.

Who it's for

Sellers

Give buyers more than "works fine, never mined". A certificate shows what a standard test measured, so a good card can stand out from the rest of the listings.

Buyers

See the test results before you pay. When the card arrives, check it's the same card and that its memory and compute still pass. No account needed.

Marketplaces and shops

A certificate link or QR code can sit in any listing. Anyone can open it and check it against this server's public signing key.

If you're selling

  1. Create a free seller account. Certificates are tied to it, so every certificate traces back to a person.
  2. Run the test. Open the GPUVerified app and choose Certify my GPU. It takes about 10 minutes; the card gets hot and loud, which is expected.
  3. Share the result. You get a grade, a certificate page and a QR code. Put the link or QR code in your listing.

If you're buying

  1. Before you buy: open the seller's certificate link, or paste its ID on Verify a card. Look at the grade, each check, and the test date.
  2. When the card arrives: install it, open the GPUVerified app and choose Verify a card. Paste the certificate link.
  3. Read the result. In about 2 minutes the app tells you whether it's the same card and whether memory and compute still pass. If it is, the certificate page shows that a buyer confirmed it.

What a certificate is, and isn't

A certificate records how this card performed in our test on one day, at factory settings. It is not a warranty, it can't tell whether a card was used for mining, and a determined seller who controls their own PC could still tamper with the app. Read the limits before relying on one.
