Frequent Game Freezes & CTD with STEP Setup

[AFineWar]

I'm following the STEP Skyrim Revisited setup here with minor changes.

I use BOSS to sort.

I've tried using HiAlgoBoost and ATTK to help with game freezing and crashing but it doesn't seem to help me.

I run on High Settings but even when reduced to Medium the same problem occurs just less frequently. I would like to know how to elimnate it alltogether.

I've deactivated (and started a clean save) mods like Water, and other 'heavy' texture mods but I still crash.

I use Mod Organizer to install and keep my mods organized.
