Macbook 15 2011 GPU, Fake or not? "made in china"

[Salvatore951]

I spent 320$ for 10 GPUs for macbook 15 2011 (5 x 6490m and 5x 6750m) I received them but it's written Made in China, date 1204 and 1208, while in the original broken one it's written Made in Taiwan.
Are them fake? Seller told me that AMD has 5 manufacturers, 2 of them are located in china, is it true?
I have always seen "made in Taiwan" on AMD chips, it sounds strange to me.

That's from SEE-IC right?
I have no idea where these things are made but the chip is probably genuine. The story is it's been knocking about for a few years and probably kicked accross the floor a few times. I have been told that some litttle china man just found these somehwre forgotten about in a dark corner of the warehouse. Not sure how true that is but looking at the chips in the die it can't be far wrong.
I think they have graded these chips on how beaten up they are and price accordingly.

If it's not from SEE, I have no idea.
Personally I'm not buying these graded chips. There are factory fresh chps floatting about.

Duke will be able to tell you that one but...
The fact that they are old and battered, might be an issue.

Are you re-balling them with lead solder?
Using a profile or eye?
Removing all edge bonding from VRAM?

They look fine. If you bought them as "real new" from SEE then chances are very good they are actually good. Cannot 100% confirm from a picture like that.

Do you re-ball with lead solder.
Do you remove all edge bonding from VRAM.
Do you use profiles or use your own sense.

Don't buy these 2012 battered chips. I would not trust them to work even though they are likely genuine, they have had a hard life.
I did buy one of these chips. It was the least battered and the highest price of these old ones and it worked but I have it on good authority that it would be a mistake to buy a shit load of them.
