It's one major part of a multi-part solution Step Modifications recommends for dealing with this limitation on 32-bit games. ENBoost is included by default in ENBSeries versions that support it, and can be implemented as a standalone memory manager without the graphical effects from ENBSeries.

The effectiveness and performance of ENBoost is determined by a number of factors, such as size of system RAM / VRAM, quality of video card, version of Windows OS, CPU, and even motherboard memory channel speed. Fortunately, there are a number of ENBoost settings to help account for the variety of system configurations. Step Modifications considers ENBoost to be an essential tool recommended for ALL Skyrim LE users. In order to understand how ENBoost works, it is important to first know how some 32-bit applications manage memory. Skyrim LE will be used for this explanation. The main Skyrim LE game executable, TESV.exe, is a 32-bit Large-Address-Aware (LAA) application.

This means that although TESV.exe can only use a maximum of 2GB of system RAM on 32-bit Windows systems, it can access up to about 3.1GB of system RAM (4GB minus about 900MB of system resources) on 64-bit systems. To drive the video card in displaying the game's 3D rendered graphics, TESV.exe must store object geometry (the shapes of things in the game) and texture data in its memory space, as a cache. This cache is then copied to the video card's VRAM to display on the screen.
