I doubt this is possible in modern hardware given the bandwidth & switching speeds they operate at.
- jrockway 5y agoProbably possible. You're not going to connect up like 32 eBay oscilloscope probes to someone's computer and get their data, but you could build a custom RAM module that saves interesting data. Obviously there are computing devices that operate at the speed of modern day CPUs and memory -- modern day CPUs and memory! I think that these aren't widely available because if you want someone's data you can email them and say "hey I'm the CEO and I need your password right now, I'm locked out of my account!" Much easier than engineering a 4GHz logic analyzer into a DDR4 form factor.
