Is this shit going to be prohibitively expensive?
Going to do a new build for a 5080, so should I be looking out for this shit?
Apparently some new motherboards for Arrow Lake will be using this.

    Its 99% for laptops, it gives LPDDR5/X the ability to be socketed while still using less power and being easier for the IMC to reach stability with faster clocked memory
    If its ever added to desktops before LPDDR6 then it will be pure novelty

      LPDDR has it's own form factor, LPCAMM. That's a CAMM, not LPCAMM. CAMM was however originally intended for laptops.

        CAMM2 standard addresses LPDDR5 and DDR5

        • 1 month ago

          CAMM2 addresses the physical standard, which IS shared, but the pin assignments at minimum are completely different between LP and non LP.
          For example, G01 on CAMM2 is a power enable pin, while on LPCAMM it's a ground. So swapping either one would completely disable the power regulation circuitry and likely wouldn't work. I haven't yet analyzed the electrical differences between DDR5 and LPDDR5, but in that dimension, it likely wouldn't work either.

    Basically, the whole purpose of this is fast as hell ram, but goddamn sure the difference would be at best of 5% more speed than regular 6000hz ram.

      LPDDR5 and LPDDR5X chips are binning well above 8000MT/s right now, some standard offerings are going to be 9000-10000MT/s very shortly. Thats quite a significant increase in bandwidth for systems that need it like laptop SoCs with a large IGP and NPU.
      LPDDR6 is also significantly faster, with higher yet again effective bandwidth, so getting this standard accepted in the industry now will only help later adoption when it really matters.

      It also reduces board complexity, placing all of the advanced routing on the memory module itself, so its cheaper for system builders who can pass the cost of the memory directly to you as a premium lmao

          CAMM2 modules has a bus of 128bits, the same width as the modern CPU memory address. One CAMM2 modules is effectively two DIMM/SO-DIMM.

          but having no upgradeability sucks, yes.

            What do you mean? Its 5 screws holding it in, what's to stop someone going from a bar of 6000mt 32gb to 10gt 128gb in the future? If anything, this should be the end of bespoke ram slots for motherboards, unless they scam it by doing camm3 for ddr6/7 in the future.

            Thanks for the honest discussion, everyone.

            >Money
            Exactly, they'll find some way to frick it up with planned obsolescence.

            It's cheaper to upgrade 4 DIMMS or 2 So-Dimm then one single CAMM2 slot

            >Cheaper for 4 dimm
            Bullshit. Have you seen the price of higher speed ddr5? Also, as others have said, no one does 4 sticks for xoc or gaming. 2 sticks of 7200mt 16gbx2 is still north of two hundred burgers, I doubt a single camm of equivalent speed would cost more than that, the mobos however...

            The main problem is that you can't just buy 1 or 2 modules, and fill in the rest later. Mind you, there are versions that should allow modules stacked on top of each other, but it's anyone's guess to see if that arrangement takes off.

            >upgradability
            That's a good point, but just like with all computer components, there should be a healthy second hand market hierarchy from xoc/gaymer fomo/server to savvy buyers to poorgays just like there is for cpus, gpus and mobos.

            Server RAM often isn't often compatible with consumer platforms, because of the inclusion of ECC. Ryzen technically has ECC support, but often motherboards aren't equipped to have it except edge cases.
            Also, there's sometimes incompatible upgrades. A friend of mine tried to upgrade his Dell box with more RAM but it wouldn't POST with it in.

            It's not the ECC, ECC UDIMMs are electrically compatible with non-ECC platforms
            The issue is with Regiesterd DIMMs and Load reduced DIMMs which are not electrically compatible. They have a buffer or register before the actual memory to reduce electrical load on the IMC.

            You're right, I meant workstations where some of the same fomo types get ridiculous workstations, only to fomo into newer gear in the short term. That's where I assume the 4 sticks guy was coming from. Even if they do hold on to them for the mid term, that quad channel ram usually easily works dual channel in hand-me-down systems.
            >A friend of mine tried to upgrade his Dell box with more RAM but it wouldn't POST with it in.
            I hate to do this to you, but skill issue. I have a dell vostro 200 that I thought died for a similar issue. Turns out a ram stick died and it didn't like running on just 3 sticks. He's probably dumb and tried using ram the shitty mobo couldn't handle.

            4 dimms isn't a thing on ddr5 unless you plan on downclocking to 4400mt/s or lower

            There will also be half wide CAMM2 which is the same as one DIMM but with no easy upgrade

            Won't that half size model still be equivalent to dual channel since all of the pins would still be populated? The only variables should be speed and memory size. right?

        Still haven't been convinced ram speed matters dick
        The arguments have been
        >it makes your games at 1080p with a 4090 faster
        >it's just faster ok, bigger number must be better, it accelerates everything I can prove it (the "proof" being just a memory bandwidth test)

            More like, even with DDR3, affordable parts would NOT run at advertised speeds even when QVL certified. The promises keep increasing, but price-performance parts have consistently failed to deliver those promises. So we know that the only thing that's "improving" with these forced changes to new standards is manufacturer profit.

    I look forward to a future where gpus will be more efficient when they will no longer have to hold the ram on the same board as the core. Perhaps this will be a step towards that.

      Well stackable modules on consumer boards will create variation in the requirements for heatsinks, which opens the door for yet another overpriced accessory to be pushed to market... so it might happen after all, incentive is there.

    I doubt it. It's just a PCB. At worst it's gonna cost a bit more than DIMM until and if it reaches wider adoption which I would expect because DIMM is somehow someway becoming a fricking bottleneck.
    I'm all for it though... You could stick an actual heatsink onto that for once and at least according to what I heard from a finngolian troony, RAM will struggle to clock higher if it gets hot.
