Fake gpu for 2011 macbook pro 15?

[Salvatore951]

I ordered 10 gpus from aliexpress, I payed them 25$ each after I raplaced it, macbook boots fine, loads system but no video. Is Gpu fake? 6490m 216-0809000 are dated 1710, 216-0810005 are dated 1717 and 1613, 216-0810084 are dated 1708. Is there a way to understand if they are fake or not?

(216-0810084 comes from a different seller)

Yes they are all fake. I don't see any real GPUs on Ali at the moment. SEE on Ebay has some real ones at the moment.
Look at the side of the GPU all the fake ones will be darker brown color, new ones will be much lighter in color. Also the die is not perfectly flat as it has been sanded and polished.
File a claim for that Ali garbage you got!
