Raspberry Pi 5 with 16GB Ram??

The Raspberry Pi 5’s firmware probes the DDR mode registers instead. The engineer explained that the circuit, connected to one of the RP1 chips, can be read by sysfs once the Raspberry Pi is booted up. The RP1 manages various I/O functions, such as the USB bus, GPIO headers, MIPI camera, and display connectors. Upgrading the Raspberry Pi 4B to 16GB of RAM in the past worked after a fashion, but the operating system never saw the extra memory. The official Raspberry Pi wouldn’t even finish booting. The initialization screen showed the 16GB of RAM, but boot up halted after the rainbow screen. The Pi 4B booted when installing RISC OS, but the operating system only saw 4GB of RAM. In theory, we might assume a successful Raspberry Pi 5 upgrade to 16GB of RAM could be possible with firmware modifications. However, we must be satisfied with 8GB of RAM for now.

This is the kind of engineering I love to enjoy You proved a lot here, Subscribed!

Made it 5mins in then realised brain cells were melting together.

When I saw a video linked in an article I'd would have expected it to be more popular. I certainly wasn't disappointed though.

Could be a voltage or trace length matching issue with the PCB. I am thinking they would have included upgraded ram if there wasn't a constraint. I think they wanted to stick to the specific form factor. 🤷‍♂️

Bro, im almost understanding you my friend..im a newb and love it ...thx

Attempt to upgrade Raspberry Pi 5 with 16GB of RAM results in a bricked Pi. Even though the CPU supports it, the Raspberry Pi 5 refuses to play nice with extra memory. We've seen our fair share of attempts to upgrade the memory on the Raspberry Pi single-board computer (SBC), some of which have been successful.

Here is a sub for all that effort :)

WHY ? Orange Pi 5 + is a Octa-Core (8) Core CPU.GPU, NPU with 16GB Ram, I like my Raspberry Pi's but its only a quad core...

Sorry for your fail, but in a 35 min video, which is certainly to long you could mention this debug setup a little. After you don't show it: is it the pico debug probe?

Ish!Ish! New sub here, keep on keeping on! Xx

It may be power supply, 8GB version has additional power supply, which 4 and 2GB versions do not have.

Its like a good movie....im a 3rd in to this....hope it dont cause distruction...😅😅

1g has 1k 2g has 2k 4g has 4k 8g has 8k ...

good job

Do we know that the BCM2712 SoC is actually capable of addressing 16GB of RAM? I've found while designing boards for similar SoCs that it's not too uncommon to be limited to an 8GB address space.

thanks for posting the trials and failures as well , a lot of hardware hacking results in blue smoke and failure

Turn your phone camera 90 degrees. Landscape mode makes all the difference and it is the default for REAL cameras for a reason!

here i'm saving to buy just one pi 5, and this guy is breaking them like they cost nothing

yeahhh, no. just get an rk3588 with 16 gigs or more
