Memory in RAM

[Estam]

I have a quick question regarding switching off a computer and whether what is in the ram is there when switching back on? Does the ram retain anything when the computer is switched off? Thanks.

No.

Unless you count forensics.

Thanks for the info... Sorry I have to ask this but what do you mean by forensics?

Other than the arcane but interesting example raised by Emulex -- there's a reason it's called "volatile" RAM.

The only way anything remains of a previous session would be through successful recovery of a computer sleep state.

This is the main reason we have Sleep and Hibernation. Sleep for when you have power available, Hibernate for when you do not.

Is there a way of dumping all the ram on switch off. I run a piece of trading software that gives me an error message halfway through the day that I am out of global memory that's originates from the software and I'm trying to figure out what the problem is. It's a decent laptop and have up graded to 3g ram. Any ideas, thanks...

Make sure you have a sufficiently large Page File. That is used as a memory supplement, i.e., Virtual Memory, on the system drive. You should also consider upgrading your memory to at least 8GB, but that would require a fresh install of the 64 bit version of your OS.

What software is giving you this message? Global memory is usually used as a synonym for your virtual memory, which is space on your hard drive that Windows uses as if it were RAM, once you have run out of RAM.

edit: And yes, 8GB of RAM is generally considered the minimum for a business machine these days.

Not necessarily. If he is already running X64 then he can just trhwo it in and call it a day.

But check your page file.
