@@uwuanims yes it's possible, however may not be cost effective

I'm unable to read that has I can't boot up the pi past the SDRAM check, but my other pi 5 which was a 4GB originally and demodded from the 16GB and installed a 8GB I have as a server runs around 47 to 52 at idle

Taking a look at 27:56 it doesn't look like the Pico debug probe because the PCB on the probe he's using is red as opposed to the regular green. What he's using doesn't seem to to have the couple of JST connectors that the pico probe has as well. My best guess would be a FT232RL USB to TTL convertor.

Saving? You need to save for a $100? Maybe get a job.

@@edenassos bruh do you even know how much it costs here in India, it takes a whole month salary of average middle class guy, and I'm a student its not easy to get job as a student here, and even if i get a part time job, I will have to work for 5 months to get a raspberry pi 5

@@James_T_Quirk only discovered orange pi 5 after I bought a raspberry pi 5, I enjoy modding and tinkering.

@@oliverer3 no I'm not sure just it can handle bandwidth speeds of up to 17GB/s

@@oliverer3 Addressing Capability: The ARMv8-A ISA confirms that the bcm2712 is capable of addressing 16GB of RAM, as it supports a 64-bit address space.. got that from the robot lol

@@handymandan4736 I'm not certain of this but I believe that's the maximum a chip based on the armV8-a instructions set can be designed for, more specifically 16GB per core cluster not something that is guaranteed. As an example the rockchip RK3568 is based on the same architecture and can only adress up to 8GB while the highest end chip in that series the RK3588 with two CPU clusters and no stops barred can address 32GB. Again all of them sharing the same armV8-a ISA. So I could see it being misleading. The BCM2712 using cortex-a76 cores does make it more likely that it can address a larger amount of RAM though. Again do take this with a major grain of salt, I design PCBs not CPU architectures so I could be completely incorrect.

Yeah that depth of knowledge is beyond me and I can find a datasheet on the bcm2712, I haven't received a response from a pi engineer saying it just not possible, like with the pi 4.

@playwithG91 where are you located? Just yesterday demoded my second Pi 5 16GB to a 8GB so to have functioning Pi and not two paperweights lol

@@handymandan4736 I'm located in Portland Oregon.

@@playwithG91 not sure how to DM you, but if you cover the costs for parts I'll do it for free. Or you could send me a bootloader to try tho I'm not sure how you'll get around the eprom signature check??

@@handymandan4736 do you got Discord?

@@zoeyzhang9866 haven't reached out to them about it, could definitely build a little adapter for under $15,

@@zoeyzhang9866 raspberry OS utilise PD IC handshake protocol with a PD adapter, my little set-up doesn't use this protocol, so although it can deliver 27w pi OS will still see it as an under performing power supply, not the case when using ubuntu, in any case you can always turn off the pi OS load shedding function, just from my observation don't know for sure

@@handymandan4736 Are you interested in any expansion board?

Solder flux paste for the clean up, not to remove,

@@ray-charc3131 I find it satisfying to be able to take something and mod it make it better, but definitely would not recommend starting out on the pi 5 just start with smaller smd chips and slowly work your way up, I started with a cheap gas soldering iron and just removed the tip, it had enough hot air for small stuff but was really good practice.

@@martinparker9044 it's not bricked.. Yet.. I can reinstall the old chip and it'll work fine, waiting a little while longer in the hope that maybe a firmware update will be released that supports the higher ram, probably be released with a pi 5 B+ version...

@@handymandan4736 fingers crossed and I look forward to your next video.

Thanks

@@cameronrich2536 lol yeah wasn't the best, might need to hit skip a few times

What a joke people are these days! Do you have any idea how difficult it is to do a video like this? It's not just record and done. He is doing everything he can to relay this information clearly. This is important! He is explaining why this doesn't work, so that others don't make the same mistake, or so that the community can investigate further, and hopefully find a solution. If you don't want to watch and listen to a seasoned engineer talk technically about shit you don't understand? This probably isn't the kind of content you should be watching

@@Aeronkat Maybe you can explain the spurious S in explaining. 😉 If you cannot spell, maybe you shouldn't be commenting! As for the video, there is a reason why professionals use a script.

@@SpeccyManThank you for pointing that out for me UwU I give you a one out of ten for your vigilance sir. Although, I can't help but notice you too had to edit your comment. Out of all three paragraphs I wrote, I had to edit one thing. You however, wrote three sentences. So, I'm going to have to take away a point, sadly for your inadequate position to have pointed it out in the first place. I thought the UK had developed a rather prestigious reputation for their proper English skills. 🫢 Oh well（⌒_⌒）

Possible maybe, but the pi 5 as a very powerful power management IC so I would think power isn't really the issue, plus the 8 and 16gb chips have the same power ratings

The whole memory is on the old chip so the software is on the old chip so you would have to flash the boot up on the new chip to run the firmware

​@@InspirationalOctopus-pi6dkit's a ram chip not a rom chip

@@handymandan4736 still have to be flashed

@@handymandan4736 you gotta register it some how

@@InspirationalOctopus-pi6dk correct I have loaded the latest bootloader firmware from raspberry Pi, stil the same result. I can just flash it, the bcm2712 boot rom checks for a firmware signature

So it is firmware 🧓🏻👵🏻💣☢️🦅🇺🇲🇺🇲🇺🇲

Nice work getting it to that stage though-hopefully they add support at some point (and maybe an official 16GB version!).

Thanks Jeff! Love your work!

As the current firmware can read the chip manufacturer and its size, I am hoping electrically everything should work. Looking at the data sheet it appears electrically everything would match up to the 8GB chip but the 'Die Addressing' is what is different. Page size, array prefetch, number of rows, configuration 256Mb x 8DQ x 8Banks.

Sorry we are having difficulty with the website being hacked, I will let you know when it's up again and operational
