CTD due to Memory problems

[ariakan602]

So I decided to restart and remod skyrim after about a year or two of not playing. I'm not terribly concerned with the look of the game and more concerned with gameplay and enjoying getting new weapons.

However, about 10 hours into the game I started getting regular CTDs after only a few minutes of play (which of course makes the game unplayable). This is my mod list and loot order list:

I believe this problem to be due to the memory issues inherent in skyrim. My PC is very high end running 64-bit Windows 10:

32Gb RAM

Threadripper 16 core 3.4Ghz processor

GTX 1080

I have tried multiple fixes including adding memory blocks to skse.ini and using the custom memory blocks inside of crash fixes, but instead of fixing the problem, these generally make the game crash on the initial loading screen. I would just like to play the game with minimal interruptions and this is really frustrating. If anyone has any fixes (including different ways of doing the fixes I have already tried), that would be helpful.

So far using the custom memory blocks with crash fixes I consistently get this error:

01 Oct 12:00:47 Skyrim has failed to allocate memory! Possibly running out of memory. Size / alignment of object being allocated was 5592560 / 0. Some things you can try:

1. Make sure ReduceSystemMemoryUsage=true is set in enblocal.ini - if you don't have ENB then install ENBoost and enable this option.

2. Try set AlignHeapAllocate=0 in CrashFixPlugin.ini - if you get additional crashes then put back to 1.

3. If it's during ShowRaceMenu then close the menu from time to time to free memory.

4. Enable CustomMemoryBlock in CrashFixPlugin.ini to reduce memory fragmentation.

5. If it's during ShowRaceMenu then disable UseOSAllocators=1 and re-enable after character creation is completed.
