data persists in DRAM even without power

My own experiments in disabling DRAM refresh indicate that the machine can keep humming along for twenty seconds before a fatal error occurs without refreshing the DRAM at all. If you're willing to tolerate a high fault rate, several minutes sounds like a perfectly reasonable window to extract useful data from recently used DIMMs.
