I built an AM5 system because I wanted to ensure that if I want to upgrade it, I won't have to buy an entirely new motherboard. Coming from Intel who change their socket every two weeks, I thought it was a great idea at the time.
The cost wasn't prohibitive, the kinks ironed out quite fast. But I don't like DDR5 RAM. Like, it's RAM, I don't notice anything spectacular about it. What I do notice, is that it takes FUCKING AGES to post!
Startup finished in 20.971s (firmware) + 4.818s (loader) + 785ms (kernel) + 4.440s (initrd) + 7.741s (userspace) = 38.757s
graphical.target reached after 7.697s in userspace.
It's taking 21 fucking seconds to do some kind of "memory training!" It used to be over 40 seconds! For what? No noticeable difference in user experience other than it taking forever to boot.
