Skyrim die Nutzung von 4GB Arbeitsspeicher ermöglichen - Tutorial

Von diesen 4GB zwagt sich ja auch das Betriebssystem ein bisschen ab, sodass man am Ende nur so 3GB(genaue Werte kenn ich nicht) übrig hat.

Probleme mit invreaseuserva können in Verbindung mit manchen Treibern auftreten, insbesondere bei Grafikkarten, die auf Onboard-RAM zurückgreifen, weil dort das eine GByte Kernelmode-Speicher nicht ausreicht.

I should add a note about the /3GB, /4GT and /PAE Windows boot.ini switches, too, because they often come up when people are talking about 4Gb-plus Windows PCs.
They are all useless to you. You do not want them.
/3GB and /4GT are config settings for different versions of Windows that tell the operating system to change the partitioning of the 4Gb 32-bit address space so that applications can use 3Gb and the OS kernel only 1Gb, as opposed to the standard 2Gb-each arrangement. They don't help at all with the 3Gb barrier, and most applications don't even notice them, so desktop users lose kernel memory space (and system performance) for no actual gain at all.
The /PAE boot.ini switch, on NT-descended Windows flavours, activates the Physical Address Extension mode that's existed in every PC CPU since the Pentium Pro. PAE can also be enabled by the /NoExecute entry in boot.ini, which turns on support for the NX bit which you probably also don't actually want.
PAE mode, in its proper form, cranks the memory address space up to 64 gigabytes (two to the power of 36). The computer can then give a 4Gb addressing block within that space - or even more, with extra tricks - to each of several applications.
PAE's no good to the everyday 3Gb-problem-afflicted user, though, for two reasons.
First, it presents 64-bit addresses to drivers, and thus causes exactly the same compatibility problems as a proper 64-bit operating system. Except worse, because now you need PAE-aware drivers for 32-bit Windows, instead of plain 64-bit drivers for a 64-bit OS.
From a normal user's point of view, PAE gives you the incompatibility of a 64-bit operating system when you're still running a 32-bit OS.
For this reason, Microsoft changed the behaviour of the /PAE option in almost all versions of WinXP as of Service Pack 2. They fixed the endless driver problems by, essentially, making /PAE in XP not do anything to addressing any more. All versions of WinXP except for the x64 Edition now have a hard 4Gb addressing limit, no matter what hardware you use them on and what configuration you choose. All PAE does in those versions of Windows is activate NoExecute support. Which, once again, you probably don't want.
This isn't a big problem, of course, since XP is not meant to be a server operating system. But it's still mystifying to people who try the /PAE flag and can't figure out why it doesn't work.
Oh, and just in case you for some reason still wanted to try PAE: It eats CPU time, too.
(You can read more about boot.ini switches as they pertain to memory and driver breakage on Microsoft's page for driver developers, here.)

This trick was all very well with computers like the original IBM PC, but when people started making PCs that could have more than 640 kilobytes of system memory, that system memory grew up into the addresses reserved for various other hardware. Now new workarounds had to be found if you wanted to find that last few kilobytes to run productivity software or games, and it all became very traumatising and hideous.
I apologise to any readers who have now remembered things that cause them to rock back and forth and mumble.
