Well, what really prompted this crisis is AI, as well as Samsung shutting down some production (and I have to say I don't think they mind that the pricing has skyrocketed as a result!)
But yes we're going to need more fabs for sure

If the shortage of RAM is because of AI (so servers/data centers I presume?), wouldn't that mean the shortage should be localized to RDIMM rather than the much more common UDIMM that most gaming PCs use? But it seems to me like the pricing is going up more for UDIMM than RDIMM.
Also vary a bit between winter a summer, basically in winter they can get away with putting a bit more volatile compounds coz it's colder
Which, every modern ECU will do automatically based on output from the knock sensors.
In theory, your average Camry running on 87 is pulling spark timing to ride the edge of knock for best fuel efficiency by being lean, but how much? It was designed to be safe on even kinda shitty gas, that has lower than 87 octane at points, and the ECU is going to err on the side of caution.
That naturally aspirated 2AR-FE in a Camry does not have the ability to compress harder, so if you put 93 in it, it may only be able to "utilize" the extra knock resistance up to say 89 by advancing spark timing.
Meanwhile your average Golf TSI probably can, and the VW GTI I have demonstrably gets better gas mileage on 93 octane, even though it is "rated" for 87 octane (and therefore has a lower mpg claim than it is capable of), but this was an engine that previously was rated at 91 octane and nerfs itself so hard on 87 that it is dramatically easier to stall, and the power figures are rated on 91 octane anyway.
You are almost certainly spending more money on gas even if you eke out a percentage point or two extra mpg on higher octane fuels, as they are priced at higher margins and have lower scale.
Wouldn't that mean that a shortage of DRAM chips should cause price difference in all of them? Not sure that'd explain why RDIMM prices aren't raising as sharply as UDIMM. That the fab and assembly lines have transitioned into making other stuff makes sense why'd there be a difference though, as bradfa mentioned in their reply.
The manufacturers make the individual chips, not the modules (DIMMs). (EDIT: Some companies that make chips may also have business units that sell DIMMS, to be pedantic.)
The R in RDIMM means register, aka buffer. It's a separate chip that buffers the signals between the memory chips and the controller.
Even ECC modules use regular memory chips, but with extra chips added for the ECC capacity.
It can be confusing. The key thing to remember is that the price is driven by the price of the chips. The companies that make DIMMs are buying chips in bulk and integrating them on to PCBs.
Quite a few unbuffered designs in the past had a "missing chip". If you ever wondered why a chip was missing on your stick, it's missing ECC. Don't know if it's still the case with DDR5 though.
Also with DDR5 each stick is actually 2 channels so you get 2 extra dies.
Was reading a series of displeased posts about it. Can't seem to find it now.
If so, that's terrible news. It was already difficult enough to find ECC RAM for "workstation" class machines (i.e.: High end, non-server CPUs that support ECC such as AMD Threadripper).
