Tehát van egy asztali gépem ubuntuval felvértezve, és mindehez 5Gb RAM-om. Szeretném kihasználni. Hogyan lehetséges ez?
Csak követni kell a következőket:
Fel kell telepíteni ezeket a csomagokat a gépedre.
sudo apt-get install linux-restricted-modules-server
sudo apt-get install linux-headers-server
sudo apt-get install linux-image-server linux-server
Restart után látnod kellene az összes memóriát a gépedben.

Linux cannot use more than 3 GB RAM per process on a 32 bit machine (using the default CONFIG_VMSPLIT_3G=y).
But if your CPU supports PAE (http://en.wikipedia.org/wiki/Physical_Address_Extension) - which is very likely - you can use more than 3 GB RAM for the whole system.

Can you explain how this is even possible? The addressable limit on a 32-bit processor is 2^32 => 4 GB. Thus, it seems there should be a hard-cap at 4GB. 32-bit Windows actually gets a little less than this, because additional address space is reserved for other hardware I/O.
How does this separate kernel (I assume that’s the difference) provide addressing over this cap?

You want to use your system for gaming - and you install a kernel made for non-interactivity - the server flavor..
Sounds like a bad choice if you ask me..
Better way to do it would be to grab the sources and config for the desktop kernel, add PAE support yourself, build a package.. Done in a couple of commands.. or just go for the 64 bit version..
.. oh, and you should probably also explain a bit about PAE-mode and so on, not just write “install server kernel”..
