You can freeze the computer, remove the DIMMs, and then pop them into a different machine to read them: https://electronics.stackexchange.com/questions/32189/freezi...

I thought that wasn't possible since DDR3 or 4?

[ATsch]

Smaller capacitors will keep their charge less long, which makes this more difficult, but I understand that there are no fundamental mitigations.

[jleahy]

The fundamental mitigation is full memory encryption using a randomly generated key that changes each time the CPU boots. That exists for some CPUs.

[ATsch]

Well, that's not part of the ddr3 or ddr4 spec :)

[Spivak]

Where do you store the key?

[danielheath]

CPU registers - much harder to pull off and reattach elsewhere.

There's (T)SME.
