Common CTDs, Freezes, ILS and memory issues

[hishutup]

 

 

Basic requirements to follow this FAQ

Use the following utilities and have some idea of what they do.

• ENBoost: This extension moves the DX9 texture cache to a different 64 bit process. This reduces the chance of filling up the 32 bit process with textures causing random CTDs.
• Crash Fixes: This is an SKSE plugin that helps catch some issues that cause skyrim to CTD, freeze or hang. 
• Some form of memory fix:
  • SSME: Made redundant by SKSE memory tweaks.
  • SKSE memory tweaks: This changes the initial heap size to make it larger. This avoids the issue where skyrim will not increase the heap causing it to CTD, freeze or hang. This method requires some input for the correct size. This can be found by using Memory Blocks Log. This is a workaround to an issue.
  • Crash Fixes OSAllocators: This is a fix for the same issue that SKSE memory tweaks workarounds. This is a true fix but has its share of issues.
  • Crash Fixes CustomMemoryBlocks: This is a fix to some of the issues caused by OSAllocators. By breaking the heap into smaller blocks, the memory can be allocated and freed as needed. This method requires some input by observing how high you need to set the blocks size. This can be viewed in the console if the toggle is enabled.

 

Info that is typically useless:

• Papyrus logs: These are NOT crash logs. Typically, the last entry could be several minutes before you even experience a crash. Any useful info is typically debugging code in scripts, this is usually removed/disabled before a mod is released. This is a very helpful tool to modders, but not to users.
• Windows logs: These are rarely of any use to a user.

 

Issues caused by SKSE memory tweaks:

Problem: I randomly CTD.

Solution: Check the size against the memory blocks log. If the last element is close to the max size then you may need to increase heap 1 by some amount(~128 MB increments is accurate enough). Heap 2 doesnt need to be increased as it spawns more like it should.

 

Issues caused by Crash Fixes OSAllocators:

Problem: I get "Skyrim has failed to allocate memory"

Solution: This is caused by memory fragmentation and there isn't really a solution for this. Its suggest to use the custom memory blocks instead.

 

Issues caused by Crash Fixes CustomMemoryBlocks:

Problem: Stuff isn't loading in as expected.

Solution: Check to make sure the size is appropriate.

 

How to read and interpret Crash Fixes crash log:

I don't know, I'm curious myself. The hex given isn't a formid, its a memory location by my understanding.

 

 

 

 

 

This is the easiest solution to the memory issue.

 

Install this manually into the "Skyrim" folder(with the TESV.exe)

SKSE Plugin Preloader

Install this manually by moving the SKSE folder into the "Skyrim\Data\" folder

Crash fixes

 

Then open the "Skyrim\Data\SKSE\Plugins\CrashFixPlugin.ini"

Modify the "UseOSAllocators=0" to "UseOSAllocators=1"

Save.

 

You should be good now.

 

I'd recommend removing the old methods of heap modification, ENBoost is fine.

 

[spoiler=Old Post]

I made this sticky because there is a sudden up-rise in CTD relating to the memory tweaks not working. It is flooding The General forum and has kind of spread to the memory blocks log mod topic. 

 

If you are curious how the memory tweaks work, there is an amazing post by keith over here.

 

There are several reasons for one to CTD or freeze but the most common one is that the SSME/Memory Patch 3.0/SKSE memory tweaks are not applying for some reason.

NOTE: SSME is no longer needed and should be removed and replaced with the SKSE Memory Tweaks.

Safety load is also not needed anymore and may cause unexpected issues.

 

 

First, please copy and paste the following into your SKSE.ini file

Make sure your ini is located as such ...\Skyrim\Data\SKSE\SKSE.ini

If you follow STEP check this out.

[General]
ClearInvalidRegistrations=1

[Memory]
DefaultHeapInitialAllocMB=768
ScrapHeapSizeMB=256

To find out if your memory tweaks are working correctly, download and install Memory Blocks Log.

Run the game through MO, I would recommend fully loading into the game but the main menu will suffice. After which close out of the game and open MO again if it closed on you. Go to the overwrite folder and navigate to the "SKSE\plugins\" folder and open up the memoryblockslog.log.

 

Your log should look similar to this:

logging of blocks enabled
logging max values only
Timer disabled
Block1 Block2
512MB 256MB

However, people that experience a lot of crashing will have something like the following:

logging of blocks enabled
logging max values only
Timer disabled
Block1 Block2
256MB 256MB

The most common "fix" is to open the "Modify Executables" window by clicking the gears on  the top part of MO and select the SKSE executable and add the Argument 

-forcesteamloader

It should then look something like this.

After which, click the modify button and then relaunch the game through MO then close it and make the comparison again. 

 

If your results did not change then make a post below, otherwise search for topics that already exist in the General forum. If your particular issue does not already exist then make a new topic and there will be someone to answer your questions.

 

[minos55]

when you delete the ini files the next time you start the game they are created again.

[Nozzer66]

If you're using MO deleting the inis in that documents folder probably wont do anything. You'd need to delete the ones in your MO profile and re-edit again.

[phalen]

If you're using MO deleting the inis in that documents folder probably wont do anything. You'd need to delete the ones in your MO profile and re-edit again.

...  uh... what?

 

so i must delete the inis in documents folder - which will then be recreated when i launch the game, then exit game, and re-edit in MO.

 

how is that different from using the existing files?  surely they would be the same after the new file + edits?

[GrantSP]

Deleting the ini files in 'My Documents' will have no impact on your already created profiles in MO. So don't even bother with them.

 

Each time you create a new profile MO copies the contents of those ini files and creates its own versions in that profile's folder.

These, the 'My Documents' files, shouldn't be touched and left exactly as the game creates them.

 

Either delete the ones in the current profile or create a new profile to test if the ini settings are corrupted somehow. The 2nd option is the better.

 

Since you initially spoke of the map key crashing the game, have you changed that key assignment to anything non-vanilla?

Do you have a standard keyboard and language setting in Windows?

Have you checked that a comlpletely standard game with NO mods at all does this?

If working backwards from what you currently have setup is proving fruitless, work the other way.

Start from a basic install and add what you believe to be the problematic mods until the CTD happens, then remove all but the last installed and check to see if it just that one or a conflict with a previous.

[phazer11]

You go to your MO folder then delete the ones located in the MO profiles folder for the profile you'd like to delete the ini settings from. Going into the ini editor in MO and ctrl-a to select and then pressing delete should do the trick as well. Then just launch the skyrim launcher from MO and it should regenerate the files.

[phalen]

Since you initially spoke of the map key crashing the game, have you changed that key assignment to anything non-vanilla?...

no, its when i try to access the map - with the M key or through the menu.  it crashes regardless of the option i choose.  and i've played skyrim before with no problems accessing the map. (i have over 450 hours logged in skyrim).

 

i will give the delete .ini thing a try tonight if i get a chance..

[phalen]

omg!!!  the problem is in my MO ini files!

 

i first replaced the ini files with my original ini files created by skyrim when you run the normal launcher (i have a habit of keeping originals).

 

loaded game, tried to access map - crashed to desktop.  ok, problem not in the My computer > Documents > Skyrim .ini files

(i thought maybe i put something there that i shouldnt have).

 

 

then i physically removed the two .ini files in MO profiles directory, and guess what, it works now.  ffs.   

 

now how do i locate the problem in those files?   the ini tweaks are scattered in the mod's detailed instructions page.   is there not one page where all of the .ini tweaks (for STEP: Core & Extended) are located?  has anyone ever attempted to do this?

 

anyways, here are my ini files contents (from MO directory).  on memory side:  2Gb VRAM, 16Gb RAM

The skyrim based INI tweaks are at the top of the Guide. There shouldn't be any tweaks in the mod pages other than those that are specific to those mods, such as SKSE.ini changes. No Skyrim.ini nor SkyrimPrefs.ini tweaks are located in the mod pages. If there are, please notify us so we can change that.

Just completed a Skyrim Revisited Legendary Edition install.

 

The game crashes only when I am moving while outside, playing in first person view, but not when in third person view, not when I'm idle, and not when I am inside. 

 

Possibly it is a VRAM issue?

 

I'm giving GPU-Z a try but does anyone have any ideas on what in particular about first person view while moving outside that would crash my game?

 

Thanks

[richardo111]

Hi to all, i do not know what i am doing wrong, i have my skse folder with the ini (not txt extensio) in the folder following STEP SKSE installation (I use MO), and becuase i saw in other vids about skse installation differ i have that SKSE folder also in syrim/data, with the skse.ini in it

 

I loade both MemoryBlocksLog and MemoryBlocksLog in both SKSE folder, not MemoryBlocksLog.log shows anywhere

 

What am i doing wrong?

Please, help, now i don't even now if the memory patch is workign, having very randoms CTD's sometimes takes long time, sometimes having several of them in a row.

[Nozzer66]

You don't need two SKSE folders. If you've added the needed .dll files and launcher to Skyrim directory and then added the SKSE scripts as a mod via Mod Organizer that should be all you need. Create your ini file in the Mod Organizer made SKSE folder.

 

Don't add a second SKSE folder and ini to Skyrim/Data.

Edited March 31, 2015 by Nozzer66

[richardo111]

ok, I will try as you say, but seems for some reason not working

[hishutup]

so...

Back to Blocks 1 size discussion.

 

I noticed that I have been getting ILS significantly more often which isnt a big deal because I'm just comparing textures and whatnot but I took a look at my memoryblockslog.log and it showed this and Im curious if anyone wants me to try some stuff? I'll likely increase blocks 1 and move on but its there.

[RedPanther93]

I'm getting stuck at the loading screen. Once the loading screen is "complete" and I should appear ingame it only displays the frozen image of the loading screen, but I can hear the sounds ingame.

It al started with me exiting the game and when next opening and trying to load my save a message appeared saying there was content no longer avaible. So I went to MO and checked wich esp was missing. It was the BirdsHFclean.esp .

I activated it and tried loading my save. No error message appeared. But then the issue I described before happened.

Any ideas what it could be?

 

I have already used Memory Blocks Log.

Your issue is probably something with enb, config files or your hardware.

 

I've never seen something like your situation so I can't really guide you.
