How to Spot Memory Types for RX 470 / 480 (Hynix, Elpida, Samsung, Micron)

Looking to buy RX 470 or 480 for your mining rig? As everyone knows now that the best memory type is the Hynix (31 Mh/s) then comes Elpida (31 Mh/s), Samsung (28-29 Mh/s) and Micron (bios cannot be modded, maybe 22.xx Mh/s and that’s it, send it back).
I am going to help you to understand how to spot what type of memory the cards have by just reading the serial number on the box.
Very important to know is that this serials may be available only for Sapphire models, another thing is that this is not yet confirmed 100% so i am showing you what i got till now, this results are reported from different users.
