Thanks Sir,
But if I put the serial number of my OG 512gb I can only order an 512
If I put one serial number of the 2tb I can order all the size of ssd
Oh sorry, I too did checked with a serial number for a 2TB and not with one for a 512 GB MacStudio...
this is insane. Logic boards are identical.
So the question is
Can I put the bigger size ssd if I order with the “wrong” serial number ..??
Yes you can.
NAND modules are not "paired" with a specific board, as I showed it previously with my upgrades on M1 Mac Studio.
Only the data you are putting into the NANDs are "ciphered" with the unique ID enclosed in each CPU, and thus can not be "decoded" on another Mac Studio.
But you can anytime put any properly configured 2TB card in any Mac Studio, providing you reformat them / reinstall the OS with AppleConfigurator.
I'll try explain a little bit further :
In factory, "factory blank" NANDs are soldered on the boards.
Then, after that, the NANDs are configured in a sort of RAID configuration :
- 512 GB configs use 4x 128GB nands in 1 card
- 1TB configs use 4x 256 GB nands in 1 card
- 2TB configs use 4x 512GB nands in 1 card
- 4TB configs use 8x 512 GB nands in 2 cards (which order is to be respected)
- 8 TB configs use 8x 1TB nands in 2 cards (which order is to be respected)
You can order on Apple Self-service repair program a single 2TB module (661-34239) from
any serial number, put it in another M2 MacStudio with
any serial number (just respect the single 2TB module configuraiton = put the single card in the 00 slot), and restore with Apple Configurator and it will work, 100% garantee.
You can do the same with ordering a kit of 2x 2TB modules module (661-34240) from
any serial number, put it in another M2 MacStudio with
any serial number (just respect the dual 2TB module configuration = card 00 in slot 00 and card 01 in slot 01), and restore with Apple Configurator and it will work, 100% garantee.
etc.
What will never work in trying to put 2x "single 2TB modules" (661-34239) as a 4TB configuration...
because they won't have been programmed for that, and that's why Linus Tech Tips or Luke Miani did failed in their attempt to upgrade M1 Mac Studio.
