this is so cool imo

while memory dumping attack is nothing new, literally freezing the DRAM sticks using liquid nitrogen so that data remains intact even after power loss is something i didn’t know about, and personally find very interesting

AMD’s Secure Memory Encryption (SME), which is in the Linux kernel, mitigates this

You can forcefully enable SME by passing mem_encrypt=on to GRUB’s GRUB_CMDLINE_LINUX_DEFAULT entry

Perfect for some amazing overclocks!

afaiaa liquid helium is used for that already

or do you mean specifically memory overclocking competitions? is that a thing?

Liquid nitrogen is used for overclocks in general, probably also for RAM. I don’t know the differences with liquid helium in this case.

There are overclocking competitions, the setups are quite amazing.
