In the summer of 2019, Crucial was among the first brands to demonstrate 32 GB unbuffered memory modules, which were based on Micron’s 16 Gb DDR4 chips. Now after a bit of a wait, those 32 GB UDIMMs as well as 32 GB SO-DIMMs have finally hit the retail market.

Crucial’s 32 GB unbuffered DIMMs and SO-DIMMs are rated for DDR4-2666 with CL19 at 1.2 V and DDR4-3200 with CL22 at 1.2 V operation. The modules are not equipped with any heat spreader and since they operate in JEDEC-standard modes, they are compatible with a wide variety of PCs that can support 32 GB UDIMMs in general.

At present, Crucial’s 32 GB UDIMMs and SO-DIMMs are available as 64 GB dual-channel memory kits priced at around $330 at the company’s website. Interestingly, the faster DDR4-3200 kits are only $2 more expensive than the slower DDR4-2666 kits. Meanwhile, expects Crucial’s 64 GB dual-channel DDR4-2666 SO-DIMM kit to arrive on February 3, 2020.

It is unclear why Crucial did not start selling its 32 GB UDIMMs and SO-DIMMs to general public earlier, as there are a number of brands that have been offering competing 32 GB UDIMMs using the same Micron chips for months now. In any case, Crucial’s 32 GB DIMMs are finally available.

    Does this mean that we'll see 32GB single-dimm laptops with soldered memory now? Seems like soldered memory is limited to 16GB, at least for the slimmer lines of laptops.

    Maybe, but I'm hoping not. Single channel memory leaves a bit of performance on the table due to the memory bottleneck. Sure its somewhat workload dependent, but it is a little annoying to get a nice new laptop that's hamstrung by a pennies-on-the-dollar shortcut the OEM took by using one instead of two SO-DIMMs.

    There will still be plenty of low cost machines that can't go above 16GBs regardless of what the OEM wants. Intel limits their addressable space, such as in the brand new i3-10110y, to a max of 16GBs. Sure, that isn't an excuse for higher prices alternatives, but it still gets us a glimpse of what is on the minds of OEMs.

    Also, for many common workloads, the performance difference is often times only detectable by benchmarks. Then again, there are still laptops shipping without any SSD.

    That's a good point, I'd want dual-channel memory too. What about those Dell 15" OLED laptops? They seems great, except they are limited to 16GB... I believe one DIMM. If only they put two DIMMS in them.

    This one for instance only support 2x8GB, instead of the expected 2x16GB:

    I'm not paying $3,000 for a laptop if it's still limited to 16GB. 16GB is 'ok', but not enough for a full gaming machine these days if you mod games and all of that.

    I don't think you can call it a "module" if it's soldered on the motherboard...

    I long for the days when laptops had 2 SO-DIMM slots.

    IF you take something 17'inch they will.
    in 15 inch you need to checck,
    in anything smaller don't even waste your time.

    There are plenty of 14" and 13" laptops with 2 SO-DIMM slots, and even some 12" ones.
  • Retycint - Thursday, January 30, 2020 - link

    But if the slots are removed then the laptop can be made even more compact, or with a bigger battery, or thinner etc. SODIMM slots are humongous relative to the size of some ultrabook motherboards, and sometimes it's worth sacrificing upgradeability for portability. Especially when 80% of consumers will never open up their laptop anyway
