This is fantastic, I love seeing people replace SMC with consumer level hardware and know how. Great instructions for others to follow.

Why not 16GB? Why not 32GB?

EDIT: MadEDoctor claims in the YouTube comments he is going to give a 16GB mod a try and report back results. Also, 32GB chips are in excess of $100. Helps to read.

Hi guys, I have sad news about the 16GB upgrade...
Important update: There will not be a 16GB upgrade as I intended yesterday... I know there will be so much hate about that, but there is the reason.
So as probably many of you already noticed I order the majority of my stuff from Aliexpress and so do the RAM chips I am using. Today when I got to order the 16GB chip I realized something very suspicious, the prices for the 8 and 16GB chips were identical (2 - 3$ difference and we are talking from the same seller) and so I decided to check the chip number to confirm that the chip I am ordering has the advertised capacity. And to no one surprise the chip they sell is actually 4GB and not 16 as listed.

As I did more research on this I found out that there is only one LPDDR4 Mircon chip that was made. The problem with that is I can't find it available anywhere, so it is impossible to me to make the video happen. You will find its name below. I will be extremely thankful if somebody could find it available anywhere.
This is the name of the real 16GB / 128Gb chip that is needed for the upgrade: Micron D8BKW or Micron MT53E2G64D8TN-046 AUT: A https://eu.mouser.com/ProductDetail/Micron/MT53E2G64D8TN-046-AUTA-TR?qs=W%2FMpXkg%252BdQ6VXnrtne2CXQ%3D%3D
I feel really bad for misleading you... I am sorry! 😔

That's a lot of LPDDR4 for one chip. So, Arrow and Allied (US distributors) were out? Digi-Key?

Hi, I was thinking about the same upgrade, because RPI4 BCM chip is said to have 16GB physical address space (Eben Upton's claim).

I can only suggest to contant manufacturer directly and ask for samples. Should suffice for a test.
