If that is your load order, you may need to run BOSS. Load order can cause the problem you describe.

BOSS can help you get a good handle on where to start with load order. BOSS, however, isn't perfect - but it'll get you close. Once you've gotten as close as you can get with BOSS and/or Nexus Mod Manager, you'll need a program like Wrye to create merge patches for those mods that stil do conflict in more subtle ways.

 

There are times where it doesn't have to be even that: high poly meshes and HD textures can overwhelm Skyrim too, depending on what is going on in-memory at the moment. Remember, just because your PC is beefy and has greater than 4GB RAM, Skyrim as a 32-bit program has that 4GB limit ... if you cross that threshold, even for a second, CTD ... it runs out of room (within itself) to process all the resources a cell is trying to load.

 

The reason it is more prevalent in the open world is because of the number of cells and sheer number of resources involved. If you know your mods are getting along pretty well, but you also know you're using hi-poly meshes and textures (all those "pretty" mods come with a price!) that come with some mods, entering the console periodically and typing pcb (purge cell buffer) can help free up some of that memory usage. That comes at a price too, as previously-cached cell resources have to be reloaded ... but it can help.
