ENB is a graphic and memory enhancement tool.  ENB is often used to increase and improve the graphic capabilities of Skyrim.  For the purposes of this discussion, we are only focusing on ENB’s Memory Management.

Please note, there is far more to ENB than is discussed here… consider this page a “quickstart” guide.  Visit this link for more on ENB.

Anyone with RAM matching or exceeding 3.2 GBs should be using the ENBoost patch or a full ENB. It allows the game to use more RAM than normal 32 bit applications.

If you do not have an ENB and DO NOT want one; download and install ENBoost, you will also need to use the latest ENB Binary found at ENBDEV

Open the ENB Binary folder and extract everything in the “Wrapper” folder into the Skyrim Root Directory (not Data (one level below) – example .Skyrim).

Now take an ENBlocal.ini from the ENBoost Archive that fits your hardware (based on Video card brand and VRAM amount) and replace the one located in your Skyrim folder (one level below Data).

ONCE you have ENBoost installed; open the Skyrim Root Directory and open the ENBlocal.ini with notepad. Check the following settings and alter them appropriately.

The above setting determines whether you have a full ENB or you are using ENBoost. Users using ENBoost should set this to true, otherwise if using a full ENB leave as false.  Also set the following:

[box type=”info”] [PERFOMANCE]









EnableCompression=false  ;Setting to False can reduce stuttering or set to true for high end systems with high end video cards

ReservedMemorySizeMb= ;This may be set to 64, 128, 256, or 512. Start as small as you can without experiencing stutter in game. Most 64-bit users will use 128.

VideoMemorySizeMb= ;This is set according to the following formula: If you are the lone 32 bit user, set it to 2048. Otherwise set it in Mb according to VRAM + RAM – 2048. So for example, I have 8 GB of RAM (to see how much you have, go to Computer -> system properties (it’s at the top), and 2 GB of VRAM (to see this… well the easiest way is to google your card. Alternatively, go to control panel – adjust resolution – advanced – it will show your graphics card. The Dedicated Video Memory is the amount you want. If you have switchable graphics it will not properly and you will have to resort to google. I set mine to 7168 instead of 8192 because I run a lot of programs in the background of Skyrim. Do not set yours *higher than the formula allows. The amount caps at 10240. This number must be a multiple of 1024; if it is not, you did it wrong.*



Once you’ve learned a little something more about ENB, you are free to alter these as you see fit.

Users with 64-bit systems may get even better results with:
However that setting has also been reported to cause crashes for some.  No harm in trying.

Note: AFTER you install the ENB binaries and configure it to your system settings. If you have trouble running Skyrim via SKSE and experience a CTD at the Bethesda Logo Screen, it is most likely due to your system missing the DirectX 9 Library.
