No question is naive ...
Either it is :
A- an honest valid question.
B- A ridiculously hilarious question.
Or
C- outright dumb one.

Yours and Maemish's question is an honest valid one.

In the most rudimentary of parallels to keep it as close to home as possible...
think of it like the n8x0's that have 128 mb of ram WITH the ability to give a tiny bit of oomph with up to an additional 128 mb of ram from allocating "virtual memory" to it.
It helps some ..sure.
"allocating" can help a bit..
can help a lot even...
But it only helps with processes and progs which normally would handle an expected load from the device in question
For example...
You can't run world of warcraft (I do not play ...I like more high brow like Neverwinter nights) on a pentium I ....no matter how much virtual fictitious ram you manage to allocate. (along with a plethora of other valid reasons as well)
BUT ...the processes and progs that would normally be able to run on the pentium I (perhaps even a few borderline slower heavier ones too)..you could run a few more of at the same time...or they would be a bit snappier ...
But that would be the extent of your ability..

In short.. nothing takes the place of dedicated ram

So if one were hoping to double or triple or whatever ...their ram in such a way...
you can fake out the system only so far...
but when process(es) or progs which are beyond the ability for the system to handle normally, need "actual" serious ram to run and look to the availability to utilize it...
It won't be pretty as your device tries its best to accommodate and does this in your hand instead

(calls it like I sees it...personally I aim for B or C...A is stultifying -ly boring....since it is predictable and has usually been asked 1000 x before...so ask something way out there...may have a "eureka!" come of it...like a battery mod using electricity from potatoes ...way out there..outright hilarious and borderline dumb / mad...but it would probably work...just need a lot of potatoes or one giant potato hooked up to it...BTW- We REALLY need this mod...For years we have had the super smart solving issues ...and we are now hitting the brick walls...its time to bring in the mad and crazy folks to break through those walls with their ingenious ideas and pulpy bodies ...and solve the unsolvable ...)
