Raspberry PI 4 - 8GB has additional voltage regulator, the question is, is it also able to supply 16GB chip?🤔 By the way, the chip exchange was carried out professionally and cleanly - respect!

Best of luck getting the RAM fully working on the Pi! I am inclined to believe you will need a corrected hardware map or similar to prevent having any of the RAM addresses used or reserved for hardware instead of system RAM.
But I read somewhere in the Raspberry Pi forums, that to address 16 GB of RAM more address lines need to be wired to the CPU. Maybe the foundation did not do that? I have no experience how to find out if that‘s true however. Would explain to me, why it suddenly stops - it probably tried to use some of those additional 8 GB. Did you try to boot 32 Bit Raspbian? Maybe it‘ll boot using only the lower 3 GB? Also the 32 Bit version uses hugetables to access anything above 3 GB - would be worth a shot to try and disable that feature.

About why it stops... All OS versions made for Raspberry Pi (obviously except RISC OS) have a bunch of config files, which tell the OS what exact hardware it's running on so it can manage the resources properly. It should work kinda like a switch-case algorithm. Since 16GB version was never released, it is not included in those config files and so the OS just goes into a break-like state.
Did you check to see if there's any additional logging in the serial port? Kernel panic? It's possible that the graphics memory is allocated in a place where the software is not expecting it to be and may need to carve out a section with cmdline options.

The BCM2836 and BCM2837 used the same basic memory controller design but fixed the bug allowing them to support 1GB. Supporting 1GB also required a very specific layout of chip.

Hello. Raspberry PI4 Model B - 4Gb. What chip is installed in Wi-Fi+Bluetooth? My Bluetooth stopped working. Is it possible to replace it, where can I buy it? Sorry for my bad English, I'm using a translator. Thank you.
Hello! Sorry for the late answer I just very busy lately... So it is repairable, by replacing the chip if this is indeed the problem. I can't tell you exact chip number at the moment, but I will check it when I have some free time and I will write it here. Also I don't have any idea if you can actually buy it or not.
Yeah, I did every single thing that you can imagine. In the end, one of my Patrons looked at all the info and data sheets available and we came to the conclusion that - The hardware (the memory controller in the SoC) just can't manage the whole 16GB of RAM, even though the Pi recognizes them... Now I feel kinda stupid, but angry because I really think it wasn't that hard for the "Engineers" in the Pi forum to just explain the issue and why exactly wouldn't the 16GB work on the Pi. But they chose to be cocky and just say (it can't work, locking the tread and also deleting links) without giving any explanation why...
Hey if you upgrade a steam deck from 16GB to 32GB you'd have a product that could sell like hot cakes. (Deck uses an apu so 16gb is shared between cpu and gpu)
In my oppinion the memory is overlapping with other IO. If the Firmware or OS wouldn't recognize the memory it simply woudn't recognize it and done about it and just boot with less memory. Try limiting the memory reported to the OS by applying a kernal command line option like "mem=1G" then slowly increase until you hit the overlapping IO registers. It is quite possible the circuits or board simply don't have enough address pins for more than 16G and then you just can't use a part of the 16gig. But then 15,5Gig also would be nice to have. It is also possible the physical RAM is split by the IO region, don't know the memory map of the Pi4, then you would need to add the memory manually in chunks - back in 486 days it was "physmem=0x12345678,0x100000 or something like that but I think this option is no longer supported. Interesting: forums.raspberrypi.com/viewtopic.php?t=262747

So technically if i just buy 8gb chip for a 2gb version no software modification ? the easy way
Yep
Can we upgrade to 32 gb
would the "MT53D512M32D2DS-046 AIT:D" work you think
Yeah, but that is 16Gb chip which equals 2GB :)
@@MadEDoctor how is 16gb = 2gb
@@mr.potato8841 Gb stands for gigabits and GB for gigabytes and 8bit = 1byte so you take the Gb and divide them by 8 to get GB
BGA 200 Chip?
I would love to be able to buy a Pi with 16GB But this form of soldering, is not one of my skills.
Please try and to run VMware esxi for arm on it!!!!
Great job, please add some contact details to your about page so people can use your services
Great suggestion, thanks!
hey an os that might works is windows 11 for arm
can be done something like that on a raspberry pi 3b+?
Sadly, no, because there is a CPU limitation.
@@MadEDoctor I forgot the RAM on PI 3 is part of the microcontroller.
Hello. Raspberry PI4 Model B - 4Gb. What chip is installed in Wi-Fi+Bluetooth? My Bluetooth stopped working. Is it possible to replace it, where can I buy it? Sorry for my bad English, I'm using a translator. Thank you.
Hello! Sorry for the late answer I just very busy lately...
So it is repairable, by replacing the chip if this is indeed the problem.
I can't tell you exact chip number at the moment, but I will check it when I have some free time and I will write it here.
Also I don't have any idea if you can actually buy it or not.
Here is the code of the chip: CYW43455XKUBG
Sadly I was unable to find it online.
Good luck!
Thank you@@MadEDoctor
bet because of this relationship with Sony the next RPI boards will have this epoxied.
Even more funny is that this can’t stop me🤣
Have you update the rp eprom ? sudo rpi eeprom update
Yeah, I did every single thing that you can imagine.
In the end, one of my Patrons looked at all the info and data sheets available and we came to the conclusion that - The hardware (the memory controller in the SoC) just can't manage the whole 16GB of RAM, even though the Pi recognizes them...
Now I feel kinda stupid, but angry because I really think it wasn't that hard for the "Engineers" in the Pi forum to just explain the issue and why exactly wouldn't the 16GB work on the Pi.
But they chose to be cocky and just say (it can't work, locking the tread and also deleting links) without giving any explanation why...
Sad. Thanks for the great work.
How much for a raspberry pi 16gb?
Well, it turned out to be impossible -_-
And the limitation is the SoC
Hey if you upgrade a steam deck from 16GB to 32GB you'd have a product that could sell like hot cakes. (Deck uses an apu so 16gb is shared between cpu and gpu)
Really great suggestion, thank you!
I may actually try this, but before that I need to save up a little more money :)
@@MadEDoctor Its still on summer sale. :P But, thank you for considering.
does raspbian working on 16gb ram after upgrade?
Nope. It turned out there is a CPU limitation on the maximum addressable RAM
@@MadEDoctor i have order a bulk 8gb ram chip to replace for my friend in here 😆😆 i tell them upgrade from 1gb to 8gb is real
@@hanaloginstruments8930 At least that works, yeah😅😅
I want my bord!
A w Ubuntu 23.04 jaka ilość ramu widzi wersja 64 bity?
Wersja 32 bit na prawo widzieć tylko 4GB
👍😁👍
In my oppinion the memory is overlapping with other IO. If the Firmware or OS wouldn't recognize the memory it simply woudn't recognize it and done about it and just boot with less memory. Try limiting the memory reported to the OS by applying a kernal command line option like "mem=1G" then slowly increase until you hit the overlapping IO registers. It is quite possible the circuits or board simply don't have enough address pins for more than 16G and then you just can't use a part of the 16gig. But then 15,5Gig also would be nice to have. It is also possible the physical RAM is split by the IO region, don't know the memory map of the Pi4, then you would need to add the memory manually in chunks - back in 486 days it was "physmem=0x12345678,0x100000 or something like that but I think this option is no longer supported.
Interesting: forums.raspberrypi.com/viewtopic.php?t=262747
Could you upgrade my pi?
If you want up to 8GB and you live in Europe, than yes.
I wanted to inquire if it is possible to upgrade my Raspberry Pi to 16 or 32GB of RAM too, and if so, what the cost would be ( I live in europe). PS/ Amazing work bro!
@@quanghoangnguyen3759 I don’t think there exists 32GB / 256Gb LPDDR4 in one chip. About the cost it’s actually not possible at all at this moment, because the minimum order quantity of the 16GB chip is 1360 pieces…
Ну вот слышно, что русский)
It really seems like the controller just can't handle 16GB RAM.
Ярковыраженный русский акцент
More like Bulgarian :)
yea lets just blur out the part numbers on the chip.
What do you mean ?!?!? The FBGA code is D8CBG and it can be decoded using www.micron.com/support/tools-and-utilities/fbga to get: MT53E4G32D8CY-046 WT:C as a part number
@@MadEDoctor when I was watching the video when you were soldering the new ship in place it was blurred out.
The terribad english just makes the video mysterious and better.
Have you tried FreeBSD? Maybe that works.
