RAM does not have persistent memory. Remove the refresh cycle (i.e. power off the device) and it is gone. Same goes with graphics cards. They don't magically store the last image displayed on a screen. 

However, SD Cards, HDD and SSDs do retain data after power off (it's why they exist) so guidance on them may be required. The odd thing though, is that in 5 years with a SHPO, I was never once asked for access to my offline storage media so they could have a look at what was on them. Or access to the browser history on my Amazon Firesticks (even though I'd declared them and never deleted anything).

Of course, most of the traps are there to catch out those who are trying their best to play by the rules. I'm not going to detail it here, but there is a way to use a computer that is virtually undetectable by the police for anyone who was really determined to reoffend, regardless of any monitoring software. It's my considered opinion that most of the device rules are in the "We must be seen to be doing something" category rather than have any actual effect on preventing offences.

Hi
Technically we are both right as it depends when the "power" dissipates from the "ram" module, not when the PC is turned off; there is a timescale difference in its decay and so become unreadable. Also the temperature can have an affect. But accessing it all depends on the scenario the module has  / is in. I mention it because as you mention there is always advancement and pressure put on the individual when being questioned as if the "investigator is knowable in all matters".

In my case they raise my IT background in the terms "you have the ability to hide things because of my career". I just replied "do you think Billy Gates knows everything about computers?"

Its same the reason you should not take a lie detector test after being repeatedly questioned and accused ; a movie called "Regression" is a find example of an innocent man pleading guilty to a crime though he knew nothing about the event due to the interviewing technique used. based on a true story that actually brought interview technique changes. 

I actually complained to my PPU that after numerous years I was still being accused of events / thoughts etc which had been disproved. Subsequently the emotional aspects of visits changed!

RAM loses its retention of data within seconds of the refresh cycle being removed. Effectively the data is stored in capacitors that the refresh cycle recharges. The physical size of the millions/billions of capacitors on a chip is a limiting factor on how long data could be saved for. It would take a huge decree of sophistry from a PPU to suggest that RAM is capable of retaining memory. It would never hold up on court 😉

Hi

As I said we are both right.
As it retains data; even for the briefest amount of time, it could be in all honesty be said by an "interviewer". Therefore used as a pressure question to induce the person being interviewed to say something that could allow other questions to be asked. The "retention" point does not have to be raised in Court. However, as we both have said it does, so they could in all honesty prove it; it is just the duration that would be subject to criticism, but only if the interviewer actually stated "time" factors. 
Distraction and pressure can still achieve the desired aim. 

take care and hope you get my drift
