Years ago, I went to AMD and saw this demonstrated live by engineers there. They spun up a VM with it turned off and you could basically grep a string out of ram. Turning it on, grep returned nothing. It was pretty cool. Developed by a bunch of true grey beards over the course of many years.

On consumer Ryzen chips you can enable it too if your motherboard supports it. Like error correction code (ECC) support on consumer chips it isn't "officially" supported but it works. I know MSI and ASUS (IIRC) have the option in bios for transparent memory encryption.
