I think that is stretching even optimistic state-of-the-art

Most DRAMs are rather destructive to their contents as power fades.
They don't just die at their last state: at modern system speeds power
off is a gradual failure.

I'm very skeptical.

I think modern DRAMs unpowered are going to lose their coherence rather
quickly.  They rely on a lot of power and high frequency updates to even
be reliable.

Now... there is the new magnetic RAMs... that should be interesting in a
security context.

The biggest problem though is that egress auditors have no idea how to
do their job in most cases.
