Where to buy NVidia BGA chip?

[djdynamix]

Sorry to bring up this hoary old chestnut again, but I'm trying to source an NVidia BGA chip: GT86-631-A2 as a replacement for the GT86-603-A2 in a Sony Vaio.

There are loads of links on eBay, but I've heard too many "horror stories" about re-badged seconds, 603's and 630's to trust that what I'd be getting is genuine.

Obviously, I need to stay away from Chinese ones for $10 with photoshopped pictures, but other than that, I'm lost.

Please can you recommend a good trustworthy supplier for these BGA chips?

Is there any way I can tell from the other numbers on the chip whether it's genuine or a "knock off"?

Thanks.

Me too have this problem with Bga chip, chip and other chips .

Chinese most of them are defective.

I found this one on ebay from a "UK Seller": http://www.ebay.es/itm/Genuine-NVIDI...cAAOSwpDdU5Gva

Any way of telling if it's genuine?

I can recommend this one
http://www.ebay.com/itm/DC-2012-Bran...AAAOSwPhdU98xL

The specific seller is the one you can trust.
Also mentions the date code of the parts.
Be sure to buy the parts with <new> condition as he also offers refusbished ones.

Thanks @rookieme. At least that one looks genuine in the picture. On a lot of the others on ebay, the chip number writing doesn't look right: either too "white" or the wrong font.

Does anyone else in here have any experience of that seller (Strong Exuberant Electronics (HK) Co., Ltd), or of the British seller, "ChipBay UK"?

Sorry if I sound "paranoid", but I've been caught out before and ended up buying fake electronic components online, and changing this BGA is going to take 3 to 4 hours of my workshop time (for which I could be earning 35€ an hour), so I really don't want to have to do it twice!
