What's the risks when it comes to mixing ram? I've

Meme from the DDR days of ram, DDR3 and 4 should be fine to mix as long as the voltage is supported on the motherboard

>pretty much everything says "you shouldn't mix ram, only use the same type". Is there an actual reason behind this or is it just some fucking meme?
just check the clock speeds on them, because they'll both be capped to the lowest of the two

It's a fucking meme. So long as the voltages are the same you're fine. The speeds can be different, the computer will simply use the lowest of them.

You can't mix different voltages

Can confirm: I'm mixing unbuffered ecc ram with non ecc ram on a consumer board right now and it works fine too; memtest86 passes

What happens if I do though? Will it just not work or will it somehow fuck my computer?

It's actually not a "meme", if you run mismatched RAM it will run in single channel mode and cut your memory bandwidth down to 1/2, 1/3, or 1/4 of what it should be. This mostly has no effect on applications but some like for file compression and encoding make use of memory bandwidth and will be severely impacted.
