Samsung Unveils 32 GB DDR4-2666 SO-DIMMs
by Anton Shilov on May 30, 2018 12:15 PM EST
Samsung on Wednesday introduced its first consumer products based on its 16 Gb DDR4 memory chips demonstrated earlier this year. The new SO-DIMMs are aimed at high-performance notebooks that benefit from both speed and capacity of memory modules.
Samsung’s new 32 GB DDR4 SO-DIMMs based on 16 Gb DDR4 memory ICs (integrated circuits) are rated for a 2666 MT/s data transfer rate at 1.2 V. Because the 16 Gb memory chips are made using Samsung’s 10 nm-class process technology, the new module is claimed to be 39% more energy efficient than the company’s previous-gen 16 GB SO-DIMM based on 20 nm-class ICs. According to Samsung, a laptop equipped with 64 GB of new memory consumes 4.578 W in active mode, whereas a notebook outfitted with 64 GB of previous-gen DDR4 consumes 7.456 W in active mode.
Samsung did not say when exactly it plans to start shipments of the 32 GB DDR4 SO-DIMMs. Meanwhile, DRAM producers usually make announcements after they ship the first batch of new products. Therefore, it is highly likely that Samsung’s customers among makers of high-end notebooks have already received the new 32 GB modules.
Samsung is gradually expanding its portfolio of 16 Gb (2 GB) memory chips for PC applications. Earlier this year the company introduced 16 Gb GDDR6 for graphics adapters and then demonstrated its server RDIMMs based on 16 Gb DDR4 chips. This week Samsung also mentioned 16 Gb GDDR5 chips for video cards.

personal opinion, these will go into apple mac pros. The market for that level of an all in 1 are the only ones who price is not an issue and capacity is.jordanclock - Wednesday, May 30, 2018 - link
DTR workstations also would like these.peterfares - Wednesday, May 30, 2018 - link
iMac pro uses full sized DIMMs though. Would be silly for the new Mac Pro when that comes out to use SODIMMs if even the iMac uses full sized.repoman27 - Thursday, May 31, 2018 - link
The Mac Pro and iMac Pro are Xeon platforms and come with full-size ECC UDIMMs. Theoretically, the iMac Pro and 12-core Mac Pro can be outfitted with LRDIMMs, allowing for up to 256GB of DDR3-1866 in the Mac Pro and 512GB of DDR4-2666 in the iMac Pro.These SO-DIMMs would work in the regular 4K and 5K iMacs though, so long as the platform supports them. Intel has yet to post any client platform validation results for 32GB modules.

Mac OS X currently is limited to 252GB in the kernel though.CheapSushi - Wednesday, May 30, 2018 - link
Consumer Mini-ITX and M-ATX boards should just go all SO-DIMM. Most of the pins on full DIMM aren't used anyway and DDR4 SO-DIMMs still have more pins than full DDR3 DIMMs. We don't get ECC and buffered DIMMs on consumer boards (most of the time) since artificially segmented. I don't really see the point of full DIMMs anymore. It's just floated still because no one is really pushing for it to change.bolkhov - Wednesday, May 30, 2018 - link
Two currently most important questions left unanswered:1. Will current CPUs suport 32GB modules?
And if "yes", which ones: Skylake, Kaby, Coffee? Which lines -- only -S and -H, or -U too?
2. Will 32GB modules raise "Max Memory Size" limit from 64GB to 128GB?
