I used the NMM to download it - especially as that is the first option given on the majority of the mod pages. I am aware of all of the above, and as a Win 7 64bit, 8GB RAM user with a pretty streamlined OS, was following the suggestions of the publisher of a popular textures mod to use the FNV4GB loader with his large and impressive package! Perhaps writing this in the wee hours caused me to be somewhat unclear. If you have more than 4G ram, windows and any other running processes can use that ram over the 4G allocated to the game without any risk.īben - Thank you for the quick and information rich reply, although my question remains unanswered.

Windowes still needs to use some of that ram. If you have a 64 bit version of Windows, then the game can possibly be allowed to use up to 4G of available ram. Then, Windows needs some ram to run, so all will still not be used by the game. But a 32 bit system cannot use more than about 3.25G of RAM - this is a limitation of the 32 bit addressing system and not a problem with either Windows or the game. If you have more than 2G of RAM, and you use a 32 bit version of Windows, it can help some. If you don't have more than 2G of memory, The LAA 4G patch cannot do anything, and is not recommended. Changes in Windows over the years have improved the handling of RAM making those type crashes much less likely. By allowing the program to go over, you risk crashesfrom the game trying to use RAM allocated to something else. And each program was to run in it's own ram. This is a limitation in Windows, It was originally designed to allocate no more than 2G of ram to any one program. In order to make that change, it must be running when the exe file is loaded or it cannot make the change. it is a utility that makes a small change in the exe program that allows the program to see any extra RAM memory you have that is not being used by something else. There is no reason it even needs to be in the NMM listings.

However, you MUST start the game with the patch every time in order for it to be installed. There is nothing to 'use' with an LAA patch.
