Didn't DDR3 ram basically make cold boot attacks obsolete? They don't hold any voltage when you power down long enough to even freeze the chips

Interesting, that sounds correct:

Even with cooling they weren't able to recover. However, a warm reboot, would still work. Speculating, but some laptops might have a way to force a reboot like some machines have a reset button. That'd at least restart the system, although proper BIOS config should prevent that from being useful.

hm, it looks to me like they just cover the sorts of temperatures you see in refrigerators.

any idea if work has been done on cryogenic temperatures?
