I think it's just a really stupid way to say "If 64GB is not enough and 128GB is too much, you can save some money with 96GB."

AMD's competitor is currently selling subscription models for hyperscalers to turn on CPU features on the fly whenever customers want it, so they can charge customers more for having access to various forms of compute acceleration. I'm not sure that just because someone wants it, that it's a good idea.

The article also said these configurations were more "optimal" for modern CPUs in an entirely separate point from overspending by buying more than you need. So that's not what they meant. They think there's some other magic that makes these memory amounts better for modern CPUs.

I'm pretty sure this gonna unearth some design flaws in memory controllers because they're assuming power of two sizes per rank and an even number of ranks per channel. Or some such.

Twerk from Home posted:Sure, I simplified it some and you need overhead for the OS, but once you've got enough RAM for your workload + the most active pages in cache / buffers, adding additional RAM is not going to do very much and memory is expensive. You don't want to just buy 50% more RAM than you can effectively use. So in reality it comes down to this: If your budget happens to line up that way, you might be able to get slightly more memory than you hoped for. And let's not kid ourselves, more memory is always good.

Speaking of which, anyone got any hot takes on the new CAMM memory for laptops? Every time I look at tech articles about it I see a lot of comments with people hating it, often for no other reason than Dell came up with it. It sounds pretty great to me! Why are we still putting memory in paired sticks when you could put both channels on one module? Does anyone even do 3-channel anymore? And it solves one of the most despicable things in laptops: BlankSystemDaemon posted:I doubt it, because it's not exactly uncommon to, as an example, amend 8GB soldered memory with 16GB socketed memory in laptops.

You hit a personal pain point for me, because the last person to be responsible for computing purchasing decisions felt like this, and that's how we ended up with nodes with Xeon Silver 4208s and 1TB of RAM. It's a really inefficient usage of resources to pair $800 of CPUs with $6,000 of RAM.

It's already going through the early processes of approval at JEDEC. It's pretty much destined to become a JEDEC standard at this point. Dell will be collecting royalties for its use, though I'm not sure if this is any different from the currently in-use standards out there.

It's a really inefficient usage of resources to pair $800 of CPUs with $6,000 of RAM. We're about to save a bunch of yearly repetitive cost by moving to right-sized GCP instances and storage for the Cassandra clusters we need. All it took was the usual questions: "why are we using N TB and provisioning 4xN TB?", "why does a recommended 16 vCPU node run on 24 and 32 vCPU instances?" etc. Over-provisioning just because wastes a lot of money at scale. My favorite from the old days was when the megalomaniac we'd left in charge of purchasing twisted DEC's arm to deliver us 4-CPU 21264 Alphas hot off the presses, like no one had 21264 boxes yet. He was proud that NASA(!!) had to be told to wait because he pressured them. Thing is we couldn't use them effectively at our current workloads and they were a huge waste sitting around blocked on NFS I/O. I'd even feel guilty logging onto them and seeing all that wasted cpu that could have been spent on ~space travel~. But faster is better, right? Klyith posted:It's enough for your job and is cheaper. This. Optimization is fitting the solution to the problem, not figuring out how to go fastest or biggest.
