QR Code on GPU

[Dozer]

saw your live stream. Could you find out the numbers of the other gpus and what could be the meaning?

No Title

I checked my charge I got. The 216-0810005

is 1608 d/c
PAW 533.00
price was 35$(22.03.2017) bought from my trusted dealer in china.

The "216-08..." is not printed, its etched.

There are no scratches on the caps around from probing and I found no scratches on the backside between the balls.

it has in the left upper corner a QR-Code

2016 chips with etched 0810005 are probably fake. I have seen them with 1605/1613/1630 date codes now. Do they all have the QR code?

i bought 20

16 i still have

from the 16 are 13 with QR-code and 3 without

I ordered the micrometer and will post the measures

 

[Dozer]

today i got the micrometer

i measured first the 216-0809000


I measured until now 2 of them

1. 1628 PVX584.00 1.515mm
2. 1628 PVX584.00 1.515mm

next, 2 originals

1.1109 PAA696.00 1,535mm
2.1106 P4T084.00 1,53mm



All old and new ones dont have QR codes

next time i will measure the 216-0810005 ones

and next chip i will measure i will edit this post to add it one after the other

Would expect about 0.02mm to be ground off. See if it is consistent with other chips.
