Why exactly do I need 8GB of RAM for the FOMM installer

Post by **anstand** » Wed Feb 19, 2014 1:22 pm

I only have 4GB of RAM, does that mean, that the FOMM installation will not work?

Not a big fan of NMM and I don't want to have problems later on via manual installation when upgrading to a newer TTW .

Because the original FOMM and NMM copies the entire file into Memory before placing it into your destination folder, so you need at least 2GB of FREE memory, but there is more to it than that as well. Try Prideslayer's FOMM that has been recently updated.

If you upgrade correctly, you shouldn't have any problems when doing a manual installation. Just make sure to make the proper INI edits. And you don't have to continue to use NMM. You could install it with it and then just use FOMM. Lastly, you could also just patch your use the 4GB FOMM posted somewhere around here (might be in the FAQ) and try. If it crashes, then it crashes and then you use NMM or manually install it. No harm in trying. :)

Edit: Ninja'd by Jax. Just thought I'd post that. But yeah, that's the technical answer.

Thanks for the answer, will do the manual installation then.

Honestly, just use FOMM and the substitute exe on the download page here. It works perfectly, and is significantly less crashy than NMM.

I just wish using MO with FONV was viable, it is a MUCH better method of mod installation, but for some reason FONV's HUD mods don't work if installed via MO.

To OP:

My understanding is... 4GB ram should be fine if you don't have much running at the time of install, the real issue is that the standard NMM/FOMM are not large address aware so they can't use more than 2Gb which can cause crashes.

The workarounds are to get CFF explorer and set FOMM manually to be LAA, or to get a LAA version of it. then it all works 'automated' which is easier for installs, uninstalls and sets up FOMM to be useful for all the other mods.

to Enneract: I agree the concept for MO is really great except for that little HUD issue which is caused by the isolationism that makes it work so well with other mods. What we need is a hybrid between MO and FOMM that lets you set a property flag for isolated or not. Then the hud mods and 'super-mods' that include hud modifiers could be handled within the same program but in a single shared sandbox, while all the rest of the tweaks would have their nice clean isolation.

Well... I think MO takes the mod isolation thing a bit too far. There is no rational reason why a mod shouldn't be able to read data from other mods, and anything it tries to write simply ends up in its own folder.

Shrug.

You honestly don't. I just got done installing the FOMOD on just 4gb of system ram about five minutes ago and it had no trouble. I also have NOT replaced the FOMM executable.

Just because one person exists who didn't need plenty of RAM and a LAA installer, the information must be invalid amirite?

Way to take what I said out of context. I'm not saying it's not nice to have or helpful, or that the info is invalid. I'm merely saying it can work without the requirements and that it's worth a try anyway.

Maybe I had a fluke or something.
