    Reading through the EEPROM repo issue[1] makes me a little more sympathetic to the "feature", but I still don't like it at all.

    It might help in the short term to stop dodgy resellers who mod the boards with cheap upgraded RAM to make a buck or two...

    But the Pi itself is always taking one step forward, one step back in terms of firmware. I've been tinkering with some Qualcomm boards from Radxa and things are slightly better there, though you don't have anywhere near the ecosystem you get with Pi (or onboarding niceties).

    There were sellers buying the smallest RAM units, changing the RAM chips, and then reselling them as the higher RAM SKUs. The sellers who do this don’t always care to use good RAM chips and may even use QA reject parts. When the unit doesn’t work correctly, the anger and RMA requests are directed back at the Raspberry Pi foundation.
    • Tepix 29 minutes ago
      The user friendly option would be to print the amount of RAM in very large letters on the PCB. There happens to be a lot of suitable surface on the PCB to the right of the text "Raspberry Pi 5" on the PCB anyway (§). Right now the amount of RAM is hard to read and easy to modify (move a little tiny SMD resistor).

      Drawback: You need different silkscreens for different amounts of RAM.

      Btw, if you're worried about RAM-swapped units you can already verify them as described at https://geekworm.com/blogs/news/prevent-ram-swapped-raspberr...

      Mac Minis used to have soldered on SSDs, but the 2024 model is upgradable. A lot of people purchased a cheaper Mac Mini and upgraded the storage themselves. Most people would argue this is a good thing, even if some of those Mac Minis were resold. This is no different.
    • DoctorOetker 54 minutes ago
      could it be construed as anti-competitive to block end-users or resellers from swapping RAM?
      • Aurornis 53 minutes ago
        No. Price discrimination and locking hardware are not illegal.
        • DoctorOetker 33 minutes ago
          lets try proof by exhaustion:

          in those jurisdictions where either price discrimination or locking hardware are not illegal, it is typically perfectly legal to reverse engineer for compatibility purposes. So nothing prevents such resellers from upping their game and learning a thing or two about link training and general SDRAM bringup.

          Once they have acquired the knowledge legally in such jurisdictions the product just flows in the other jurisdictions anyway.

          Courts upheld the monopolistic position of microsoft etc. for decades, but respect has no finality, "re" + "spect" to review, so later such companies were fined for their decades long transgressions.

          But during those decades it may appear legal to the average consumer.

          Inaction is not permission.

          • Grombobulous 24 minutes ago
            All of this is pretty irrelevant from a legal perspective.

            Reverse engineering is legal, but manufacturers don’t have to help you figure out how to reverse engineer their products and they’re allowed to design their products in a way that makes it difficult.

            There’s generally not a lot of jurisdictions out there that make stuff like hardware lockdowns of this nature illegal, especially for companies that are not in regulated industries or are not monopoly/oligopoly players.

            • DoctorOetker 6 minutes ago
              > All of this is pretty irrelevant from a legal perspective.

              I'm not asking for help to figure this out, and of course RP is allowed to shoot themselves in any foot they like.

              Consider Europe where such reverse engineering is perfectly legal for compatibility purposes. Let's consider an idealized scenario, there were no security bugs or other issues with the product that would justify reverse engineering RP blobs in public. When they do something like this, they are GIVING CARTE BLANCHE to public reverse engineering efforts to attain compatibility with other RAM chips. Why would you provide legal cover in some jurisdictions for others in publicly reverse engineering your own products by introducing artificial incompatibility?

              Also from a consumer perspective, RP tries to place itself front and center in maker communties, emphasizing modularity, not just hobbyists, also companies build and design end products using RP units. All of these companies must now be wondering where RP Foundations exact red line resides: can we resell an RP board in a Kiosk we made? or only for as long as it doesn't compete with RP's future Kiosk modules? Today its the RAM upgrade, but tomorrow RP modules may refuse to boot some popular Kiosk hardware intentionally. What prevents RP Foundation from eventually "not copying" end-application hardware like a Kiosk design from their customers, and then enforcing compatibility only with RP Kiosks?

              So not only are they providing legal cover for public reverse engineering efforts, they are scaring part of their customer base.

              > There’s generally not a lot of jurisdictions out there that make stuff like hardware lockdowns of this nature illegal, especially for companies that are not in regulated industries or are not monopoly/oligopoly players.

              That's a very shallow interpretation of law, looking only at what RP is or isn't allowed to do.

              There's generally not a lot of jurisdictions out there that make stuff like reverse engineering for compatibility or security applications illegal either.

                • smilespray 6 minutes ago
                  EU Right to Repair Directive specifically prohibits manufacturers from using HW/SW locks or firmware limits to block part replacement.
      • kmeisthax 34 minutes ago
        Probably not.

        Doing a RAM swap and then selling the resulting unit as if it were a Raspberry Pi of the higher RAM capacity might be construed as trademark infringement[0]. And in general it's fairly difficult to make arguments in antitrust cases that boil down to "yes, your honor, everything they're doing is within their rights but I don't like it".

        [0] At the same time, the scammers could probably get away with this by putting "Upgraded to 16GB!" in the title of their eBay listings or whatever, in the same way that fraudulent storage devices are labeled as "upgraded" (read: lying about their capacity). That doesn't impact the antitrust analysis though.

        • DoctorOetker 30 minutes ago
          I certainly agree that such a reseller should clearly state the modification, and not pretend its an authentic RPi 8GB unit.

          But if this is the real concern, they could just display the fact that "Unoriginal RAM detected" to inform the user its not a vanilla RPi Foundation product, so buyers understand the situation, but continue booting normally.

      But bricking retroactively in the field is a bad move, and sends even more anger and RMA requests back towards parties.

    The real story here is that people are selling modded Pis as higher-memory versions. And this check actually caught them + is circumventable. The restriction is somewhat annoying to a small subset of enthusiasts but seems to catch genuine fraud.
    • Wowfunhappy 18 minutes ago
      If it's circumventable, how does it prevent fraud? Seems like it would likely just hurt the enthusiasts.

      You can already check whether the RAM has been swapped via https://geekworm.com/blogs/news/prevent-ram-swapped-raspberr....

      > The restriction is somewhat annoying to a small subset of enthusiasts but seems to catch genuine fraud.

      What fraud are you speaking of?

      • alibarber 42 minutes ago
        The memory that they are placing in it has to be cheap enough to be worth their while. Which in this climate is highly probably faulty memory, or memory that runs at a different speed/spec to the one advertised to come with the RPi. That is fraud.
        • horsawlarway 14 minutes ago
          Yeah, I'm split on this because

          1: I think people should be able to replace chips on an RPi as they desire, so I don't love that they're actively preventing this

          2: As a buyer, I absolutely want to know if I'm buying an RPi that has had chips replaced

          3: A shady seller changing the SKU to mimic a better board after changing chips is just flat out fraud.

          ---

          It's the classic "Mattress tag" case - it should be illegal to remove as a seller, and fine as the final customer.

          But that's really hard to functionally enforce.

          • alibarber 3 minutes ago
            Absolutely agree.

            It's unfortunate, but given that there are so many ways you could end up with a poor quality knock-off (i.e. Amazon, sorry, 'third party marketplaces') it's probably something that skews the tradeoff quite significantly.

            I guess there are more individuals who will be upset when they can't run something on their equipment as it was advertised to them than will be upset that they can't re-solder the RAM.

            There are probably even fewer individuals who'll do due diligence in their own supply chain. Whilst those that suffer are technically suffering from some kind of crime / civil wrong - the chance of them getting a remedy for this is going to be non-existent.

      • Grombobulous 20 minutes ago
        Whether it’s fraud depends heavily on how it’s sold.

        If it’s represented as a new product or offered with manufacturer’s warranty, that would cross into fraud.

  • throwa356262 7 minutes ago
    I think the bigger problem is that this was pushed as a firmware update, bricking previously working devices.

    Remember when FTDI did this and suddenly medical equipment at some hospital stopped working?

    Raspberry Pi is going down the way iRobot did, succumbing to pressure from chinese players like radxa or orange pi.

    Sad to see industry pioneers lose to players that copy them and undercut prices using cheap labor.

    • edg5000 8 minutes ago
      Why do you think they are going down? My impression is that their prices are actually good. Especially for CM4 compatible alternatives. They fab in China just like everybody else. Although they do some or all assembly (soldering) in UK I think.

    • dave78 45 minutes ago
      > their platform is built for hobbiests and tinkerers

      I don't think that's been true for a long time. Their main market is commercial users now - reference what happened with COVID shortages and RPi prioritizing nearly all of their capacity to commercial users, leaving tinkerers with little to no stock.

    • _joel 48 minutes ago
      Maybe originally, I'm sure their larger market share is now the embedded market. The whole compute module thing.
  • kingstnap 52 minutes ago
    I mean the Pi currently makes little to no sense to buy anyway. So locking down parts barely moves the needle. The value proposition is unbelievably bad at spending upwards of $423 CAD for a 16GB Raspberry Pi. Which is literally just the bare board.

    The 2026 financial report is apparently this Thursday on Sept 24. So will see how this played out for them. Their stock is all over the place anyway with low float.

    • edg5000 6 minutes ago
      I think the Pi units have much higher margins on higher RAM versions plus RAM is expensive, so the 16GB is indeed a bad deal. For my workloads I heavily use all onboard peripeals, GPU and CPU, but need only 1GB RAM. So I get a good deal even compared to Chinese alternatives.
    • bluGill 42 minutes ago
      The pi is useful because it is well supported. Either buy a x86, or buy pi - anything else and good luck keeping it working. You need to plan on spending your time writing/maintain the drivers to keep your system working.

      Even for pi, the real value is in industrial companies that don't want to hire their own maintainers.

        Reminds me of Adobe's history to be honest. They also were big on hooking the young to their ecosystem, including turning more than one blind eye towards piracy, and once they had a captive userbase plus a lack of competition, they enshittified.

  • kmeisthax 43 minutes ago
    I think this is really dumb and stupid. Not that I don't agree with their reasoning - it's actually very reasonable - but that I have a lot of distaste from "saving the customer from themselves" type antifeatures.

    Practically speaking, though, this antifeature doesn't affect most people, because I don't think most people are willing to take a heat gun to a microsoldered part just to save a few bucks on RAM. If the RAM was socketed somehow - which at this scale and performance tier is not possible - then I'd probably be way angrier.

    > raspberrypi locked and limited conversation to collaborators

    Way to read the room, jfc. Hardbricking hardware is not the answer, see FTDI.

    I get why they are doing that... but I think there should be a way for users to flash a separate firmware, maybe tied to the hardware key similar to the old h264/mpeg license, that allows the usage of a modified board.

    PS: Arrest Sam Altman who caused all of this mess in the first place with his market manipulation stunt.

  • dannyw 1 hour ago
    That's quite disappointing. Whose hardware is it anyways? Yours, when you pay for it.
    • sbarre 1 hour ago
      I find their explanation to be completely reasonable.

      As they clearly explained, giving you the choice to swap the RAM chips would create broader systemic problems that would lead to bad customer experiences and a support burden for their organization.

      You'd be ok with that trade?

      Local maximalists like to imagine a world where everything is aligned with their own personal incentives, but then present this world as being filled with freedom and choices. Just not anyone else's freedom or choices, only their own.

      • choo-t 14 minutes ago
        They could have :

        • etch the ram around on the board itself.

        • provide a pre-RMA check so user can verify if their unit is genuine (serial number linked to ram amount)

        • void warranty on resoldered board.

      • VCFundedGenYer 48 minutes ago
        The entire point of the RPi is the user can do whatever they want with it.

        So no, it's not reasonable at all.

        Buy an Apple product if you want what you're stating.

        • camgunz 41 minutes ago
          No, RPis are very inexpensive computers. What you're advocating would considerably increase the price of a Raspberry Pi to pay for the additional support burden (if this is even reasonable--should they hire a bunch of people just to answer "you bought a RPi w/ bootleg RAM" over and over again?), and that defeats the point.
      • dingaling 37 minutes ago
        > You'd be ok with that trade?

        Umm, yes...?

        Just put a 'warranty void when removed' frangible sticker on it. Seems to work fine for PCs.

        But so many people these days seem to be brainwashed into accepting that computing devices should come with soldered RAM and locked bootloaders, they probably can't even envisage how hardware used to be. Yes, modding my device voided the warranty and I didn't care. Freedom has a cost.

        • camgunz 20 minutes ago

      Except that they have to deal with angry people who bought a dodgy chipped unit.

      Yeah it's stupid, but people doesn't know better, they'll complain loudly Raspberry PI is sh* it doesn't work and the Pi Foundation are scammers.

      • pmontra 1 hour ago
        Replacing a part voids warranty, this is common and well understood by everybody.

        I can't help thinking that they want to sell maxed out devices to max out margin.

        • alibarber 1 hour ago
          In the GitHub issue posted as another comment it's clear that what has happened is:

          - 8GB Pi is out of stock / too expensive - due to RAM shortage

          - Someone bought a load of non-8GB Pis

          - Replaced the RAM with whatever they could get their hands on (cheap enough to be worth the hassle, cheap because no one else wants it even given the ongoing shortage - so probably pretty suspicious / of dubious quality)

          - The end user buys it and has no idea it has been modified and the warranty is void

          - RPi probably don't want to spend their time supporting it. Probably can't if the memory is a load of crap, even if they wanted to. It gets bricked.

          The point here is someone bought something else (a fake pi) than they thought they were getting. Not that someone willingly wanted to go hacking.

      • dsr_ 1 hour ago
        They could permanently mark the board when they install the RAM on it.

        Since, presumably, nobody would try to sell a board with less RAM on it than shipped, a count-down scheme instead of count-up would work.

        16GB board: no holes drilled in a marked area; 8GB: one hole drilled; 4GB: two holes drilled; 2GB: three holes drilled.

        • Aurornis 1 hour ago
          These things don’t matter to buyers. When the board doesn’t work right or crashes a lot they don’t care which step in their personal supply chain is at fault. They demand the original manufacturer give them a new one for free, which they believe is the terms of the warranty.

        Why they want or don't want something doesn't matter at all.

        There is always a reason someone does any bad thing. There is always obviously some advantage to the perpetrator.

        The fact they are only reacting to some other bad actions doesn't excuse it because there are any number of ways to to react. This way is the one way they chose when they have infinity to choose from.
