pues dentro de ebay hay un vendedor que comenta esto,,, lo pongo tal cual viene en su store,, espero los ancianos del foro puedan corroborar o desmentir, ( lo de ancianos es por maestros no por edad :lol: )

Condition:
Brand new - never been used! Revised version (good underfill)



Datecode:
1102A2 (week 02 - 2011)



Batchcode:
N3P951.S1R (all chips with a batch code ending with R have the revised underfill. They won't go defective!)



Solder balls:
Leaded (reballed by us with leaded balls for easier fitting)



Important information:
Please only buy if you have experience replacing BGA chips. It takes extended technical skills as well as a BGA rework station to fit these chips. Furthermore we ask you to only buy this item if you have experience with NVIDIA chips, and know how to recognize the fake Chinese remarked chips and how to recognize brand new revised NVIDIA chips.

Please mind:

- Remarked chips don't have sharp edges on the mirror. They have been polished to remove and change the date and batch code.
- Revised chips (chips with the good underfill - produced after 0850) have a batch code ending with R.
- Listings saying "with balls" or "tested OK" are mostly fake chips. Ofcourse the chip comes with balls! And why would you test a brand new chip? Honestly, our chips are NOT tested, because there is NO need at all. We DO guarantee you it will work for a long time! If not, we will replace or refund you!
- We actually used many of this exact batch chips for our repairs. We give 12 months warranty to the customers that have this chip replaced by us. If fitted correctly, it should actually never die again!
- Reballing or reflowing a failing chip is useless. It will start failing again within a few month. We have tons of defective NVIDIA and ATI chips. If you are interested in buying this junk, please contact us for a great deal!

Lo de la fecha te aseguro que es verdad. Lo de revisar los bordes del core tambien, muchas veces los chinos mandan chips usados, y lo primero que miro es eso, y que si me mandan mas de uno, al menos tengan el mismo datacode. Igual, no hay mucha ciencia, un chip nuevo sale u$s45 aproximandamente, y uno de menos de eso, es usado.
