Raspberry Pi Zero W Chip Fake?

Hello

I bought a Raspberry Zero W from a German dealer. But he has a different chip than usual.

That's the PoP (Package-on-Package IIRC)** mounted memory chip - historically they can be from different manufacturers so i doubt it's a fake.
Trev.
** The SoC (CPU/GPU) is underneath that.

As FTrevor said, the memory chip on top of the main chip can be from different manufacturers. That looks like a Micron memory chip which has been seen before on other versions of the Pi.

Yup, the "chip" you see is the RAM, not the SoC (which is underneath the RAM). If you look closely at the edge you can make out a small layer separation between the 2 components.

So what you have "discovered" is that not all Pi0 computers use the same RAM chip. Nothing revolutionary there. Components often change over time in any system. It's quite common, actually.

EDIT: added crappy phone picture.

Thanks, then everything is fine.
