Some people, really... > I don’t quite have the courage to physically short pins, nor the patience to slowly overclock my RAM, waiting multiple minutes for DDR5 link training each time It's not clear to me: when is the DDR5 re-trained? I assembled my Ryzen 7000 desktop PC myself and I don't remember ever having to wait minutes for it to boot, not even the first time. It's a bit slower at boot I'd say than non-DDR5 PCs I had in the past but it's mere seconds, not minutes. And last but not least: DDR5 specs for ECC vs non-ECC, which price difference and speed difference are to be expected?

> which price difference and speed difference are to be expected ECC RAM uses 1/8th more memory chips, so as a rule of thumb it costs 1/8th more. They can have very different dynamics on the used market though, because servers tend to be upgraded to larger modules over time, but there aren't many buyers for smaller modules. Not a big factor for DDR5 because it's too new, but for DDR4 you can get some great deals for 8GB and 16GB modules.
