Skryim CTD when using more then 3 (3,1GB) of Memory

[prod80]

As usual Papyrus doesnt say what crashed the game, just what happened before it.... Nothing much, you can pretty much ignore it :)

 

So how about the home version that is not made for RLO? Does that work?

 

Which mod is it anyway...(link?)

[Korumera]

It's the following mod: http://skyrim.nexusmods.com/mods/33473

 

I've tested the non RLO version but it crashes just as hard. I've removed the mod loaded the save game before and just walked around near whiterun. Lot's of grass there so it's a good test and it goes up to around 2.4GB but I can see that when I move it unloads it's memory so its between 2GB and 2.4GB. So dont know why the mod is causing this but it's strange :) I'll just install an other player home and test that one to see of it causes the same issues.

Maybe try walking around in Windhelm and the surrounding areas. The mod says that it's Windhelm-themed, so it may used some resources from Windhelm. I used to have a lot of memory related crashes near and in Windhelm, perhaps yours is a similar problem.

Was just checking the mod... There's nobody in the thread reporting a CTD with 1150 unique DL's... I will give the mod a try tonight, I have both RLO and ELFX (not both at the same time) with ENB and self configured .ini's/.fx setups (ENB/Skyrim's), with a pile of texture/landscape mods, see if I can make it crash :P

 

I run Win7x64 / [email protected] / 8GB / and a lousy 1GB GTX560 Ti...

The game becoming extremely unstable once it reaches around 3.1 GB of RAM is well confirmed. While in theory the game could use up to 4 GB of RAM on a 64 bit system, in practise it can't. Also keep in mind that DX9 based games such as Skyrim mirror some of the textures in the RAM. So even if you have a GPU with 4GB VRAM, having a world full of 2k textures will probably eat up large chunks of your RAM.

Okay did some testing and walked aroud in a forest area with lots of trees and grass and it goes up to around 2,8GB but it comes down sometimes to 2,2GB so to be honest. Dont have a clue why my game doesnt like that mod.

 

edit: Started walking from Windhelm down south near the ridge of the mountains it contains lot's of grass and trees at least with the mods i'm using :)

I dunno, but I run a lot of heavy mods (high texture) flora, mountains, water, lighting, weathers, high texture armors, scripts, ENB and so on... I run hardly over 2 GB of system memory (max I saw was 2.2GB), ever. And use a 1 GB gfx card. I average outside on ~30-32 FPS and inside on 45-50 FPS.

If it's memory related, then most likely you have overdone your skyrim ini files eating up too much for the sake a visual range or LOD which will only have benefit in <5% of the cases and hardly notice anyway (like standing with your nose on the rock or viewing over the large open area outside of Whiterun).

There's mods out there to improve visuals out of drawing range which have close to zero impact on your system memory (eg. http://skyrim.nexusmods.com/mods/31982/ or http://skyrim.nexusmods.com/mods/17984/ and a bunch more when you search LOD in nexus)... increasing LOD on distant objects will eat your resources and limit what you can and cannot do when just increasing the distances to render through your ini files.

There's so many guides on internet which say change this and that in Skyrim/Skyrimprefs.ini, which hardly have a clue about what they are actually changing - It's just done by trial and error... even if a developer of a feature specifically says NOT to do that (see papyrus tweaks), still keep on going advertising to change it off the default values to something utterly insane (eg, coming back to papyrus changing the default from 75K to 4GB (lol! but extreme example...))

I never ran into a 3.1GB RAM limit yet, but if the game CTD when reaching that limit then your best go is to try the following;

• Make a backup of Skyrim.ini, Skyrimprefs.ini and if you use a custom skyrim ini file, make a backup of that too.
• Take a note of your uGridsToLoad values if you modified them from the default (5)... You should not use values over 7 as they are very unstable (so actually you can use 5 or 7)
• Remove all the mentioned ini's and start Skyrim to rebuild them with default values (you dont have to enter game - you cannot if you edited uGridsToLoad)
• Exit skyrim if you have modified uGridsToLoad and change them to whatever is in your backup files, if you use SFO also change the grass values (and if any other mod requires you to change a value in your ini files, do that)
• If you have NMM you can disable your 2K texture mod
• Start Skyrim and check your memory, it should be way lower now (assuming you custom edited your ini files for more eye candy)
• Try and enter your house

If this works then

• Enable 2K texture mod and try again

If this is still working

• Have a really good look at your ini files ...

If the above fails revert back to your normal ini's... and you can go the other way...

• Disable all your Mods except the DLC's, Unofficial skyrim patches, RLO and your house mod
• Create a new game (please do not mess with your real game this time.... too risky). Yea I know, takes some more time...
• If you need gold and whatnot just use console commands to add you gold (player.additem F 1000000 will give you 1 million :P) ...
• Travel to the location, make a save point with console command save "my test save" and try and enter the house

If this works

• Start adding mod by mod (starting with the 'big ones' (CoT, SFO and the likes) first trying to enter the house after each addition

If this does not work

• Start removing mods and try after each removal

And if all this still does not work.............

• Give up and go have a beer or 3.

Working on some tweaks indeed. I've changed some things in the ini's but not much. Only those things required by mods. I only changed uiMaxSkinnedTreesToRender to 80 (default is 20 i think).

 

I also had Lush Grass and Trees (only Grass), SFO and Grass on steroids. i've removed the first one and noticed the grass looked the same hehe. So i'm doing some test runs.

 

 

I've turned off 2K Textures in MO it's around 200/300mb difference on avarage :smile: But the game still crashed inside the house and memory went up when I fast traveled there. I've turned the value of the trees to 40 so gonna test that later on :smile:

 

Thanks for the help sofar and thinking along!

 

 

edit:

 

Okay lowered the value of the trees to 40 and disabled the HD 2K texture mod and now it doesnt crashes it uses 2.5GB (it still loads a lot inside the house) it's all wood and a lot of stuff in it. But It hates the texture mod that's obvious. I'm going to install the Lite version of the Texture pack :) that should save up some memory and while playing I dont think i'll notice it that much.

I use the lite version as well... honestly the visual difference is minimal between 2k and 4k textures (you can already see on the reference screenshots which are taken zoomed in... it does not really represent the difefrence during gameplay)... and also take into account that 4k textures is 4096 x 4096 ... the normal skyrim textures are 512 x 512 ... perhaps it comes more into context how heavy it is when you realize that 512x512 fits 64 times in 4096x4096... having your memory overload with >4GB available system memory and 3GB available VRAM is not good :P How's your VRAM doing now? looking more healthy I guess with less swapping of textures between it and your system's memory...

 

Trees to render should be set to 40, 80 is very high (4x the default ultra setting). I think mine's still on 20 even (perhaps 40, but cannot check now). Lush grass is a major pain... would not touch it as even top of the line systems struggle with it... nice for screenshots... not nice to use on a heavily modded skyrim. Problem is not using 1 high resolution texture pack... the problem is using multiple high res packs and all the other random goodness found on nexus :smile: glad the problem is found... perhaps it's time to go through your mod list and drop a mod left and right that you dont use anyway.

[Korumera]

Yeah

 

I've tested it and it's well a bit blurry then the Full version but it's okay :) and it saves memory :) lush gras is fine, i've tested that and the memory use is the same at least for me. I also use the 8kx4k resolution for pines with SFO so 80 rendered trees is a drag :) I've put that back to 40 :)
