"out of memory" crash with FNV4GB

[Matthijsschumi]

I AM LATE I KNOW, but for all them folk who still dont know how to fix

 

NVSE

 

Extract the files from the archive into the Fallout New Vegas folder, NOT into the Data folder. The src folder and text files are not needed.
In the Data folder "right click->New->Folder", then name it "NVSE". Only do this if the folder DOES NOT exist.
Open up the Data/NVSE folder and "right click->New->Text Document", then name the file "nvse_config.ini".
Open nvse_config.ini and add the following:
[Memory]
DefaultHeapInitialAllocMB=400
scrapheapsizeMB=128
Save and close.

 

The value for DefaultHeapInitialAllocMB must be between 200 and <500. 400 seems to be the best value for Fallout New Vegas, but it is recommended to play around with it a bit.

 

ENB BOOST

 

Choose the latest version of ENB, currently v0278, and click the black arrow http://wiki.step-project.com/images/4/42/Down1.gif at the bottom of the page to download.
Open the archive and the Wrapper folder then extract everything except the text files to the Fallout New Vegas folder.
Go to the Fallout New Vegas folder and open enbseries.ini in a text editor, like Notepad++, and set the first line to UseEffect=false. Save and close.
Open enblocal.ini in a text editor, like Notepad++, and edit the following lines:
[MEMORY]
ExpandSystemMemoryX64=false
ReduceSystemMemoryUsage=true
DisableDriverMemoryManager=false
DisablePreloadToVRAM=false
EnableUnsafeMemoryHacks=false <-- As a last resort, setting this to 'true' may actually benefit some people getting stutter otherwise. Beware that it could potentially cause CTDs on some systems.
ReservedMemorySizeMb= <-- Possible values include 128, 256, or 512. It may require some tweaking depending on system hardware, but 256 is a good starting point.
VideoMemorySizeMb= <-- Go here (http://enbdev.com/download_vramsizetest.htm) to get the vramsizetest tool. Run the vramsizedx9.exe. Note the number it reports back. For Windows 7/XP, subtract 170 from the reported number to get your final value. For Windows 8.1/10, subtract 350 from the reported number to get your final value. The final value is what you want to enter here.
EnableCompression=true <-- Weaker systems may benefit from this setting being false.
AutodetectVideoMemorySize=false <-- Set the VRAM manually.

 

 

NOTE!!!!!!!!

 

at the first step where you have to set "UseEffect=false". Try "true" first, for me it works on but for you it may not.

 

this fixed it for me hope it will for you 2

Obviously late to this, but in my case the solution was to clean the DLC's and make a merged patch with FNVEdit. On my current install, I got these out of memory crashes even with 4GB patching, using NVAC and tweaking ini-files etc. I was a bit surprised as I'm not even using texture replacers this time. But I haven't had a single crash since cleaning the DLC's and creating a merged patch.
