Why not go directly to the source article that has a lot more details? https://www.theregister.com/systems/2026/06/29/zuck-saves-me...

It is amazing how this is attributed to "zuck", like he actually knows these things.

That's just El Reg being El Reg (the Zuck-buck rhyme was apparently too good to pass up). But it's a far cry from their glory days, when they coined nicknames like "The Beast of Redmond" for Microsoft or "Chipzilla" for Intel...

I have always wondered why there was never a big market[1] for "cheap PCI/PCI-X/PCI-e card you can stick a boatload of your old/surplus/n-generation old simms/dimms on and use as swap/slow memory/ram disk/etc". It's rare you can populate a motherboard with a full address space full of 'new' memory, and you can teach kernels to prefer some memory to others because of speed[2], so it seems like a no-brainer. I seem to…

Not exactly the same but I'm building a NAS box with old parts. Most of my spare RAM sticks are laptop DDR4 SODIMMs. There are SODIMM -> desktop DIMM adapters... it did not go well. The system would boot 1 out of 5 times. No adjustment of memory speed settings would make the system stable.

It will be interesting to see what happens to the consumer electronics market the next few years. Companies are right now gambling that consumers will pay extra because of RAM shortages. I suspect with the cost of everything else rising as well, a large portion of consumers (remember, HN, not everyone makes tech money) will just not be buying new devices for a bit.

The interesting part of this "RAM crisis" is similar to other fields where a problem results multiple parties looking for alternative solutions. This yields for exciting ideas or workarounds that might result a post-crisis memory boom (hopefully) also for local machines. 1. Lowest, Apple is evaluating new Chinese manufacturer which means change of supply demand if indeed it has reasonable QA. ( https://www.ft.com/con…

> suddenly single channel is 'ok' Single channel RAM surely beats any disk-based swap.

of course, but I was under the impression the real shortage is RAM mostly.

Earlier quoted context omitted.

Nobody voted for it, that's true. But since reality held closely to it for decades right up to the present, it's reasonable to believe that transistors get smaller and cheaper as time passes.

"Moore's law" is a marketing gimmick. The real physical law that held for decades is Dennard scaling, which stopped to apply already in 2006 once transistors got too small so short channel effects and gate leakage kicked in.

Dennard scaling hit a wall but Moore's Law did not. Worth considering why. One of these is physical and the other is economic.

It’d be nice if there were a consumer version of this. I have plenty of old RAM.

Gigabyte had a ram disk addin card years ago. Not exactly the same but since it's presented as a storage device you could use it as OS swap space. https://en.wikipedia.org/wiki/I-RAM

observation that I've noticed recently: what's with wikipedia downsizing the hell out of images site wide? Every image I look at is garbage and I have to dig through multiple links to find the original.

At the beginning of William Gibson’s Neuromancer , the protagonist is trying to sell 3 MB of RAM in underground markets. This is often cited as one of the ways the book has not aged well. But, looking at the direction of the memory market now… maybe we just haven’t gotten there yet.

It's sort of a cool idea. "Pre-RAM" without the tracking/AI integration so it can be used for clandestine activities in a dystopian future.
