I feel like changing the width of some of the IO components on the modules is closer to "tweaking" than to "completely changing".

I wasn't trying to suggest you could do it by changing only the memory controllers and not the DIMMs.

Ah. If you make any silicon changes at all, it is orders of magnitude more expensive and "harder" than just using extra chips like normal ECC DRAM does.

I'm suggesting a change JEDEC could have made when incrementing the DDR number, basically.

Especially since the ECC overhead on DDR5 is so high.
