Now, many of us have probably run into this problem. You download a mod, or multiple mods and all of a sudden, you CTD, bug or run into performance issues. Then you search for a solution and are forced to look through every mod you just downloaded!
Well, worry no further! This guide will help you avoid ctds or other performance issues that plague many modders alike.
First off, you need the most recent version of skyrim. Go on steam and download it.

Speed up scripts/mods:
By adding more memory this speeds up scripts, go to and add
Major Causes of Crashes:
This is a checklist for major causes of crashes.
These cause 90% of the crashes modders get:
Missing Master/esm or missing plugin/esp
*A mod refers to a plugin or masters that DOES NOT EXIST. check using Wrye Bash, uninstall with nmm or/and manually remove *in data folder* mods that rely on other nonexistent mods. Causes crashes instantly on start*
*Use BOSS for load order! Also try not to use mods that do the same thing. Wrye bash fixes most issues. Check the Wrye Bash section or their download page for more details*
*check the tips and tricks section for avoiding these mods!*
This causes 10% of the crashes modders get:
Bad save files
*Almost unfixable, best option is to avoid bad mods, use Skyrim Save Cleaner and maybe it'll work*
Bad/outdated .ini tweaks
and delete the .ini (s) to refresh the ini tweaks. Warning: forces you to completely redo Skyrim Configurator or Skyrim Launcher settings*
Tips and Tricks When Downloading:
1a. Take note of the description. Read it carefully for compatibility, bug issues and installion!
1b. Usually, all you have to do is go to files and click "Download with Manager"
1c. In Files, optional files may contain compatibility patches. Check them out!
1d. Also pay attention to when a mod was last updated. As a rule of thumb 2012 and earlier may cause crashes.
2. Right in "description" currently in a BLUE background, check "Last updated". Most older mods(2012 and eariler) ARE BUGGY and will not work well.
3. READ THE COMMENTS! Very useful information can be found. If the mod hasn't been updated since 2012, this is a MUST.
WinRaR or alternative:
For WinRaR, open the compressed file and extract to a new folder in desktop (extracting to data folder itself may not work due to admin privileges). Click and drag OR copy from inside the new folder and paste it into where it needs to be.
Usually, you need to paste in here.
C:\Program Files (x86)\Steam\steamapps\common\skyrim\data
C:\Program Files (x86)\Steam\steamapps\common\skyrim
Simply read the readme.txt or instructions.
A must have for many popular mods, such as SKYUI.
Simply download, and put data folder and other files *in same directory* into skyrim folder.
After installation, remember to run SKSE, not Skyrim Launcher or Skyrim.
Nexus Mod Manager:
Download and install. Pretty self explanatory. Use launch SKSE, and if you suffer from download problems change servers:
Settings -> Download Options -> Server Location
Remember to check the mods for updates.
Download manually, and run the application.
Always run it when installing new mods! It's easy and automatic! Also, you can see which mods have dirty edits!
You can get this at nexus mod manager HOWEVER, version 303 crashes whenever you rebuild a bashed patch.
A pretty self-explanatory installer. I wouldn't recommend python or standalone executable.
Get version 302 instead. To make a bashed patch
1. Open, click "Mods" tab find "Bashed Patch, 0.esp"
2. Right click and click on "Rebuild Patch"
3. Click "Build Patch"
Wyre Bash also discovers missing masters(esm) or missing plugins(esp). Just go to
Mods Tab: If anything is "Red" find a fix!
Download using manager, and go through the install. Afterwords, note that most mods use the MCM interface that comes with SkyUI. Mod Configuration Menu is found in the menus.
Escape Key(default)-> Mod Configuration
Unofficial Skyrim Patch and DLC Patches:
Check download section in this post for download links!
Must have bug fixes! DO NOT UNINSTALL CASUALLY(usually it's another mod or save game causing the problems) or you may break your save.
There are no unsafe changes, and the patches are VERY stable.
Save Game Cleaner:
Install manually, and extract.
1. Load your save file.
2. Open the console using the ~ key on your keyboard and type the following:
save mysave 1
3. The game will make a dump file, so wait a few minutes.
"mysave.ess.txt" AND "mysave.ess"
5. Run SKYRIM Save Cleaner.exe
6. click on "fix all REFR's", Follow the prompts "mysave.ess.txt" AND "mysave.ess" are in your skyrim saves folder
7. once finished load "mysave.ess" from in-game skyrim load menu.
The application resets a lot of references, removing dead bodies etc. Use for bloated saves.
It is still possible to experience crashes, and the save game cleaner will not clean everything. When in doubt, make a new game. Some saves cannot be saved.
Install manually, extract and run.
Change the settings to what you want. It saves changes to .ini files, just choose and click "Apply". Done!
Much more useful than Skyrim Launcher.
Graphics card booster, reduces lag and significantly decreases loading times. DO NOT use outdated performance mods such as Skyboost! Most performance fixes in Skyboost were already fixed by Bethesda.
C:\Program Files (x86)\Steam\steamapps\common\skyrim
When it's running there's a pop-up before Skyrim start, and a logo at the top right when playing.
Improvements to interiors, increases performance. Very, very useful.
Generate FNIS for Users:
Adds animations to game. Download, and install. Run Generate FNIS for Users after installation, or the animations will not be added.
Unifies all SkyProc patchers for patch adding.
Download, and run the java program to patch the game for mods like Skyrim Redone(SkyRe) and Dual Sheath Redux.
Optimizes textures via compression. Download, and run.
Click under "Profiles" and choose your optimization *minimum(safe), medium, maximum*
Download, and run. Use the application only if you know what you are doing.
For simple mod cleaning:
1. In the master/plugin selction, right click and select none.
2. Use BOSS, and check which mods have dirty edits *SELECT ONLY THE MODS THAT ARE DIRTY*.
3. Right-click where the form ids are, and click "Apply Filter for Cleaning"
4. Afterwords, right-click again and click on
Undelete and Disable References
Remove "Identical to Masters" Records
A.K.A. UDR records and ITM
Dirty edits do not always need to be cleaned, usually BOSS automatically sets load orders to work perfectly. However, mods with many dirty edits are mods that cause most of the crashes.
