Does RAM perform differently under different operating systems?

Hello,
I have been told two different answers: Yes , and guess what? No!
I was told RAM will only perform differently if I change the actual hardware. What do you guys think? Thank you.

Question:
Does RAM perform differently under different operating systems? If the answer is yes, I will need to prove it using tests.

No, All RAM works the same under ANY OS.

The OS may USE it in a different manner, or allocate it differently but no in essence RAM works the same on any OS. How much is needed, used and in which ways it is allocated etc can be different though.

Can one way be more efficient than another? What allocates? If I was to test the allocation efficiency, how would I do that on both operating systems.

How certain processes are arranged, or if they are used with Virtual RAM or whatever.


What exactly are you attempting to do, Or trying to figure out?

I need to:
1) Know if Memmory RAM management is different between Ubuntu And Windows XP.
2) If so, what is the difference?
3) Create a hypothosis of which is better.
4) Run tests on the two operating systems.
5) Draw a conclusion
6) Share my conlucion

Simply, the scientific method

Memory Management is different YES.

Windows uses Virtual Memory along with RAM. I am not too sure what Ubuntu uses, But I doubt they use Virtual Memory like Windows.

Ubuntu does use virtual memory for paging in an explicitly different partition called swap.
However, that doesn't answer any of my questions mate.

Then it's the same, Swap file / Page file is the same thing. It's all virtual memory.

Maybe wait for someone who knows more about this, Lol. I have just gone and confused myself even more.
