SebastiusToday i did some digging. Turns out the 'About my mac' menu can tell you the RAM manufacturer.
The manufacturer code 0x80AD translates to SK Hynix, which is fortunate because it matches the brand i've ordered my chips from. For your record, a partial list:
- 0x014F - Transcend Information
- 0x2C00—Micron Technology, Inc.
- 0x802C—Micron Technology, Inc.
- 0x80AD—Hynix Semiconductor Inc.
- 0x80CE—Samsung Electronics, Inc.
- 0xAD00—Hynix Semiconductor Inc.
- 0xCE00—Samsung Electronics, Inc.
Further digging on the ifixit.com website turns up their 8GB model also has Hynix memory and thanks to their awesome board-photo's i can determine the model RAM on their board (i will need to open my Macbook at some point still to confirm).
It's the H9CCNNNBLTALAR-NUD chip. The ones i ordered are hopefully of the same series, the H9CCNNNCLTMLAR-NUD version. There are two letters different, of which i think i've determined that the B-C stands for the 16->32gigabit upgrade and the A->M stands for the A revision->M revision.
The nasty is that i'm unable to predict a working system because all my variables are unknown:
- Are the chips i buy really brand new and 100% okay
- Will my soldering be good enough
- Will adjusting the jumpers work
- Is there magic in the firmware of the macbooks that is (in)compatible with these chips
- And probably other stuff i'm forgetting...

ok... for those of you that don't want to open your Macs up to find the part number in "human" terms... I (kinda) stumbled on a way of finding it via the "Part number" ('Onderdeelnummer' above).
Copy the Part number from the System information
Go to a hex to ASCII conversion site, I used:
https://www.rapidtables.com/convert/number/ascii-hex-bin-dec-converter.html
pop it in the Hex box, tab out... voila!... I know... simple... saves "minutes" of time... excluding the time chasing those tiny screws around the floor! :)
I am (kind of) assuming that this will work with most manufacturers... but don't quote me on that.
You can also try Googling the "Manufacturer" ('Fabrikant' above) hex address, and that may also point you in the right direction too.
Are you sure? yes | no
