Samsung Unveils 32 GB DDR4-2666 SO-DIMMs

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.

Insert obligatory ECC comment here.

Samsung press release. Also at Tom's Hardware and DigiTimes.

    My desktops have a minimum of 32 GB of memory. But no Swap. I don't want swapping putting wear on the SSDs. I'm coming up on 3 years of no swap. Works perfectly. If for some reason I ever needed swap, I could create a swap file. It would be as efficient as a partition because SSD has no seek or rotational latency. Every sector is as near as every other.

    I start using memory if I run VMs. Or if I run a certain Java program that parses huge data files creating a model in memory.

    My Pixelbook has 8 GB memory. The Ubuntu on it has 11 GB of swap, just in case -- because I occasionally might launch Eclipse and related programs on it. But I don't treat it as a development machine.

    As for programs demanding more and more memory, they also demand more and more cpu cycles. There's a reason for that. Software is getting far more sophisticated. There is a huge difference in features between Notepad and LibreOffice Writer. Or between Notepad and Eclipse. Writer and Eclipse can edit text, but each brings a vast feature set. Things we now take for granted. Spell checking as you type. And as you type in your source code.

    Or Excel takes so much more memory than Lotus 123. But modern Excel has way more features and sophistication.

    Developers put more into software. Making it bigger and slower. People like the features, but pay for it with Moore's Law.

    As long as my SSDs don't begin developing a vibration, I won't worry about it.
