    Computers actually got slower to boot after DDR5. It was true that ultrafast boot would boot in something like 5 seconds from post, now auto memory timings are harder to get right and so require more iterations to achieve stability.

      Doesn’t memory training only happen once when you first boot the machine (or reset bios).

      I mean having a lot of ram will take a long time to post, but that’s not unique to DDR5. My server is DDR4 with 64 gigs of ram and with it’s original CPU it took ages for the post to finish.

        There are memory trainings that happen automatically every time the machine is booted. The more intense ones happen after a full shut down, but ddr4 was far less noticeable than the intense ddr5 trainings which often even need an additional power cycle to get right. These are not your typical automatic timings applied in the bios, they’re trial and error timings set by the firmware of the motherboard I believe.
