CTD when Saved Memory (RAM) reaches 100

[Erke]

I noticed that whenever my Saved memory reaches %100 Fallout crashes to desktop.
I'm on a x64 machine and running F4 as x64
I have 32GBs of ram, I see that there is at least 5gbs of free ram available and a lot of standby ram is being used like 15gb.
But when I keep an eye on the Resource monitor on my second display the "Saved memory" (whatever even that is) reaches %100 and F4 CTD.

Are there any settings or mods for fallout to better utilize the ram? Why is this happening and anybody know any workaround or a fix for this?

It very much depends on how your PC is set up. Useful video for basics of performance
https://www.youtube.com/watch?v=osKnDbHibig. Likewise it very much depends on your game so if you could provide info on your PC specs and mods being used

Use enboost https://www.nexusmods.com/fallout4/mods/332/ follow and read the instructions but in the enblocal,ini there is a setting for memory allocation and you can also use a Vram test tool so see how much memory you can allocate.

THANK YOU SO MUCH for letting me know about this.
Been playing F4 since it came out never heard about this and this is exactly what I was refering to and looking for.

Although, the link you provided seems to be only the ini profiles for ENB 0.281 from 2015 (not that the ini changes much).
I installed the latest version of ENB
(http://enbdev.com/mod_fallout4_v0428.htm).
By installed I mean coppied just the 2 dlls for the preset I chose to use
(https://www.nexusmods.com/fallout4/mods/17631?tab=description)
and have been researching since, haven't even loaded the game yet.

As I mentioned earlier I have 32GBs system RAM and 8GBs of VRAM. VRamSizeDX11.exe which is provided by the official ENB website, tells me that I can allocate 20000+ RAM for ENB but people say "10240" is the Max.
I also came across this "ExpandSystemMemoryX64" setting which is not included in the original files, which allows you to allocate more RAM but I believe it has it's own problems as well...

I was wondering if you also knew anything about these options and have any insight on how to properly set the enb?

I would truely appreciate it if you could drop a few more words on these as well.

If you allocate more ram than it needs then it doesn't matter the system will only take what it needs. But stick to 20000 as you need 3gb for Windows, 4gb for the game, 20gb+3gb+4gb = 27gb. You have 32gb+8gb = 40gb useable memory so you have plenty left over.

Anything past 0.283 is more for full ENB graphics but it is more orientated for the scenery. weather, water, sunlight fx on Skyrim. It doesn't matter as they all have the same basics but just has features that you will not use on 0.428 for example. The program will move ram to where you need it, if the graphics gets hungry and needs 12gb then the ram can top up the vram and vice-versa. There is technical but just leave it at that for now. You will see that the fps is 61, leave it at this as the calculation allows for 60 not above 61. A lot of programs limit it to 60fps and it is safe to run it at that speed.

Another thing to include in on your fallout4custom.ini, add or change the following lines
[Papyrus]
UpdateBudgetMS=2.4
fExtraTaskletBudgetMS=2.4
iMinMemoryPageSize=256
iMaxMemoryPageSize=1024
iMaxAllocatedMemoryBytes=30720

This will allocate more time for scripts to complete each frame, you may not need it at the moment but it stabilizes all the idles, fighting, etc so that they do not cause latency in heavily populated areas.

You do not need expanded system memory as a lot of these things were for earlier processors and Windows has moved a long way with gaming since then. You have a fairly good system so not that much to do.

Hopefully the above will work fully but if you get stuck, please ask. A lot of people here will help and if not they often joke but don't take them literally, it is a community and the only place where Covid hasn't got us... :)

One thing, I forgot to mention is that the initial start of the game may be slower than you are used to. This is normal as the enboost will check for memory allocation and how much it is going to need. If you have a limit and 30gb is being used by other prgrams then it will warn you that it cannot continue. Normally you sit with a black screen for 1-2 hours.

Personally, I switch off Steam cloud as I only play on one PC. Saves time for verifying the save games and speeds up both saving and loading

I've managed to get it so my game uses exactly 5.5gb out of 6gb of vram.

That is a very good setting you have. I have 2xGTX1080 so I can use up to 14gb VRam, it just depends on how you set things up. For example, I will sometimes turn the Hyperthreading off and with Skyrim le, I can use 8 or the 10 cores for the game to make it far better than SkyrimSE that replaced it which can only use 1 unless you write a special interface program. There are quite a few games which will work better without HT running but only those that incorporate the use of HWThreads, it is a matter that you understand what the game is and how it uses your system so that you can make it work better or more stable.

@Dave
Thank you again for all your suggestions, today I will try to launch with all the new settings.
As for your Papyrus settings suggestions, I urge you to take a look at this link;
https://www.reddit.com/r/skyrimmods/comments/2gwvwl/guide_papyrus_ini_settings_and_why_you_shouldnt/
Some of the settings may not be what you think they are.

[Dave]

That is for Skyrim, mostly for 32bit version. A lot of commands carry over but with 64bit not all is needed. Early creation engines needed ram to be forced in order to make it work, the engine would not use more than 2gb which meant anyone with 16gb was wasted. What it did crave was Vram and if you had a 64gb graphics card then the game would work very well. This was why modders, gamers and developers started to find ways to improve things such "ENB", 4gb memory expansion, etc. Also the tricks of ini settings were developed by understanding the commands... https://wiki.step-project.com/Guide:SkyrimPrefs_INI is a good read when you see a command and want to understand them. To read from start to finish is a little like "War and Peace" but keep it in your favorites and use it for reference.

Stick to what you have at the moment, there will be things that need to be added or changed but those will be mod dependent. Nexus provides full description of mods, what they require, how to install and how to install. To quote a good guy on these discussions, "SuperSledgeNY", read, read and read again. So many times people have problems and on the front page of the mod it says "DO NOT USE WITH xxxxx" and sure enough they have the mods on their listing. If you have a problem with a mod then check the postings there are normally answers but do not be afraid to ask, we have all misread something in the past and felt stupid when someone gives us the answer but we all make mistakes, we all have slightly different opinions and sometimes we have different answers. At the end of the day, we are a community and anyone who abuses another will be banned. There are some good arguments but we all understand it is a game and the characters are not real life.

Wait, something is wrong here. I'm running with 16gb of ram and haven't had a CTD/Freeze/etc in Fallout 4.

Fallout 4 has been running without problems save for a few quest/item bugs. I'm playing Vanilla, with only the Load Accelerator mod installed.

Ryzen 7 2700x
RX 580
16 gb ram

Again, I'm not sure what is eating up all of your ram.

There are lots of things that make one PC act differently to another and I don't want to go too technical but the motherboard bus speed can be a factor, the speed of the memory, the channels allowed but it comes down to the faster a PC can function is only as fast as the slowest item. Most motherboards cannot handle more that 2133mhz but ram is now being sold at 5100mhz. If you explore the specs of motherboards and find the reason why one is £60 and another is £860, likewise with memory. I could make a PC for £250 that would run Fallout brilliantly and I could spend £10000 and it won't run at all.

Likewise have a look at this video https://www.youtube.com/watch?v=8qkXKmpOWa0
especially at 5.10 for Fallout. Notice FPS increase but also notice temperature. If you have a good cooling system then you can run FO4 at 30fps faster without changing anything on INI's, mods or hardware upgrades. Not recommended but just interesting that's all
