im wondering what the last 3 numbers of a batch signify.. so, for example

3218C021: what does the '021' signify?

 

serialization code unless anything has changed

 

1st letter or digit = plant code (Malay)

0 = San Jose, Costa Rica

1 = Cavite, Philippines

3 = .............., Costa Rica

6 = Chandler, Arizona

7 = .........., Philippines

8 = Leixlip, Ireland

9 = Penang, Malaysia

L = ............, Malaysia

Q = ..........., Malaysia

R = Manila, Philippines

Y = Leixlip, Ireland

 

2nd digit = Year of production (2001)

 

3rd & 4th digits = week (49th week )

 

5th - 8th digits= lot number

 

10th - 13th digits = serialization code

cool thanks. but ive never seen the "10th - 13th digits". all of them ive seen on sandy/ivy follow the 8-digit format, like

3218C021

L204B515

etc

Any good batches that it's possible to buy?

 

We're putting emphasis on voltage for 5GHz and IMC...... I'd like to see binning info on what chips can do with PCI-E controller.

 

3213B472 CR... PCI-E problems start at -65. By "useful" temperatures, forced to PCI-E 1.1, else crash during windows load.

 

L212B308. No problems that I remember
