TES5Edit - Look above on how to use it as there is a tutorial there Optimizer Textures - Helps optimize Skyrim's textures, instructions on the main page and on this guide page (Files) LOOT - A very simple software, click the sort button and hit apply then you are finished. Mod Organizer - Use this TOOL to sort and manage your mods. Did you try the command line option -heapsize 'kb of ram u want to use' -high -useallavailablecores That might help. Some games 'not sure about 64 bit Skyrim' will only use a certain amount of ram regardless of how much you physically have. As some of you know there is a patch in SKSE that allows you to increase the size of the memory that Skyrim can handle this would help to prevent CTD for some people BUT for some others that use more mods or have a heavy load, playing with high ugrids still the 512 mb you get from block 1 in the default SKSE.ini is not enough, for example i at starting my game in an open area i was already. The main tweak changes the memory usage, by allocating more memory for initial processes in Skyrim. This will aid with long/stuck loading screen and crashing immediately after save load. It is recommended that always run SKSE with administrator rights.

Make Skyrim Use More Ram
Bethesda released the “4gb patch” more than 8 months ago, but this doesn’t really matter, it was just a LAA fix in order to allow the properly handling of memory under 64 bit systems. But this doesn’t necessarily mean your system will automatically use more than 4gb of RAM! In order to tell to Skyrim your correct amount of system memory you have to apply the following tweak:
Open your Skyrim.ini, usually located at the path: C:UsersyouruserDocumentsMy GamesSkyrim and search for the line under the [Papyrus] section:
iMaxAllocatedMemoryBytes=*******
Then change the value marked as “*******” with the approximate amount of your system memory, by consulting the tab below:
if you have 4GB of ram -> iMaxAllocatedMemoryBytes=2000000000
if you have 6GB of ram -> iMaxAllocatedMemoryBytes=3000000000
if you have 8GB of ram -> iMaxAllocatedMemoryBytes=4000000000
Open your Skyrim.ini, usually located at the path: C:UsersyouruserDocumentsMy GamesSkyrim and search for the line under the [Papyrus] section:
iMaxAllocatedMemoryBytes=*******
Then change the value marked as “*******” with the approximate amount of your system memory, by consulting the tab below:
