The memory chip is embedded in the SoC, how do you envision a way to do replacement of memory chips with this design/architecture?

- berbec 2y agoIt is possible but very hard and dangerous. I wouldn't recommend it to anyone. 0: https://www.chongdiantou.com/archives/73084.html https://www.chongdiantou.com/archives/73084.html
- jsheard 2y agoAs discussed in the iMac thread yesterday, LPCAMM2 makes it possible. There are LPCAMM2 modules with the same 7500 MT/s spec as the M4s integrated memory, and two of them running in parallel would match the M4 Pro. https://www.anandtech.com/show/21390/micron-ships-crucialbranded-lpcamm2-memory-modules https://www.anandtech.com/show/21390/micron-ships-crucialbra... Even if Apple wanted to support modular memory, which they obviously don't, the ultra-tiny form factor of the new Mini would probably still rule it out though. Soldering the memory down is still more compact.
- Rohansi 2y agoNo way the new Mini is too small to allow upgradability. You can buy a Windows mini PC that is not only smaller than the new Mini but also allows upgrading both RAM and SSD. And that's without using LPCAMM2 - just normal SO-DIMMs. (Example: https://trigkey.com/products/trigkey-green-g4-16g-500g-n100 https://trigkey.com/products/trigkey-green-g4-16g-500g-n100)
- wtallis 2y agoThat system you linked to is an extremely poor example. It relies on an external power brick, is incredibly underpowered, only gives one PCIe lane to the M.2 slot limiting it to ~800MB/s according to their specs (meaning it's only PCIe gen3), and has only one SODIMM slot (meaning it's operating with just a 64-bit memory bus, half the bandwidth of mainstream consumer PCs). It's basically a 12 year old PC shrunk into a tiny box and low power budget.
- Rohansi 2y agoSure, it's not on the same performance level but this isn't the only option. There is a wide range of options available in the same form factor. Here's something higher end: https://www.bosgamepc.com/products/bosgame-mini-pc-p3-amd-ryzen-9-6900hx https://www.bosgamepc.com/products/bosgame-mini-pc-p3-amd-ry... Probably still uses an external power brick but I imagine that's just to reduce costs. My point is that this size of device is already available with upgradability so the form factor isn't the issue. Apple is significantly better at engineering products than these random companies and they could surely have made this new Mac Mini upgradeable. I do understand why they wouldn't want to though!
- sliken 2y agoSure. Generally with 1/2 the memory bandwidth (or usually less), a worse iGPU, and slower CPU. That N100 is an Intel Atom, quite a bit of a downgrade from the M4 with the fastest CPU cores out there.
- sliken 2y agoM4 pro uses LPDDR5X-8533.
- wpwpwpw 2y agoI am not talking about DIMMs. Talking about the chips themselves. I am pretty sure they don't make different APUs for different memory sizes, it's just a fuse or something like that. If CPUs can use sockets, so do memory chips.
- buildbot 2y agoNope. Not reliable ones. The pin density on a bga memory is like, 0.3mm for the type typically used by apple. That’s 200 0.3mm pins that have to line up and work at 4GHz and survive you dropping it 5 feet.
