24GB and 48GB DIMMs are useful, and that's what this is about-- allowing non-power-of-2 sizes (in this case, 3x a power-of-2 is now allowed).
This has the potential to noticeably reduce costs in many cases.
- javajosh 4y agoWell yeah but it's not interesting. It's like saying there's a whole new kind of tire - that is 13.5" wide unlike the 13" tires we're used to. Useful? Yes. interesting? No.
- mlyle 4y agoWhat's interesting is subjective. It was never worth it to go to the halfway points before. Slower progress in RAM (and a higher proportion of large system cost being RAM) makes it more worthwhile to fine tune this. I think it's interesting because it's yet another symptom that we're just not getting more density of memories-- now it's justified for memory controllers to be slightly fancier to deal with this. I wish I could have more readily built a 96GB system instead of the 128GB one that I just did. I wanted overkill (more than 64GB), but I didn't need 2x overkill.
- Dylan16807 4y agoIt was never worth it, but "worth it" is a pretty slim difference here. And we had triple channel memory before, which eats of most of the novelty. > I wish I could have more readily built a 96GB system instead of the 128GB one that I just did. Couldn't you have put one 32GB and one 16GB module in each channel?

If reaching peak performance requires stuffing all the memory channels, then you still have choices that vary by a factor of 2 choices. > Couldn't you have put one 32GB and one 16GB module in each channel? It's a mini-itx board, so only 1 DIMM per channel. I also generally just prefer to put one dimm per channel in machines, because more loading on the memory bus often equals having to tune for less performance.
- fnordpiglet 4y agoI’m all for saving money. But it’s a stretch to say it’s particularly interesting news. But my wife gets excited about credit card point promotions, so I guess some folks are excited to save a few bucks and would find this thrilling. But I will always remember this article as the most disappointingly boring article, other than that one my wife sent me about Hilton Honors points.
- Animats 4y agoThis isn't a new thing. It's been around several times before, mostly as a way to improve yield where part of the memory is bad. Interestingly, GPUs don't have the power of 2 mindset. 6GB GPUs have been sold since 2016.
- mlyle 4y ago?? non-power of 2 modules for PCs are completely new to me. When has that happened before? JEDEC DIMM standards didn't allow it.
