Thanks for the suggestions and sorry for the imprecise description of memory load (KSP gives the percentage load instead of actual load in its debug file though). After installing Active Texture Management KSP with all the mods I mentioned above runs with around 2 GB memory usage and also rock stable! Big thanks for this hint! So far I've put resizing at 1 (so no resizing, just compression, preservs texture quality quite nicely) and had no more crashes during the last six hours.

Thanks for your replies - I have 8 GB DDR3, which is used to around 75 % at the moment of the crashes (according to KSP). Apart from that I'm running an overclocked i7 (prime & IBT stable, OC'ed for over two years without issues) and two overclocked GTX 780 together with three screens, giving a total resolution of 6048x1200. Everything is watercooled and "battle tested" with lots of applications and games. Bottom line: my system runs fine everywhere else, it's been ages since I've seen my last Win7 bluescreen or error message, the system is even buffered with an external UPS and I've installed as little software as possible (meaning my windows installation is basically 'naked', there are no 'optimization tools' or whatever, it more or less comes down to: Windows + latest patches + latest drivers (no betas, always stable versions) + Steam + Games). Regarding any issues with my installation of KSP: I redownloaded the game after deleting all local files in steam & manually removing the folder from steam common apps, and then I redownloaded each mod. But again while each mod individually works fine the game starts to misbehave when I want to for instance load 'Interstellar' and 'Astronomers Visual Pack' (crash right after game finishes loading all parts-files). I think Active Texture Management comes with one of the mods anyway (Interstellar, I think), but I will give it a go and install that mod manually. I should also mention that in Astronomers Visual Pack I only use 'reasonable' texture resolutions (512x512), nothing extreme. One more thing, when running KSP 32 bit the game is limited to 30 fps no matter which value I set the ingame framelimiter to). When running the 64 bit version it runs at 60 fps. Is this intentional or is this 30 fps limit already a sympton?

Hello, to make the end-game more interesting I added more and more mods to my KSP installation. The list includes (but is not limited to) - KWRocketry - MechJeb (obviously) - Alarmclock - KAS - TAC - all 'Near Future' packages - all 'Umbra Space Industries' packages and for optical reasons I also use EVE/Astronomer's Visual Pack. KSP is Steam Version 0.25 (using 32 bit), as are all mods (except Astronomer's, but more on that later) While I love the different mechanics and ressources the Near Future and Umbra Space Industries packages introduce, the game becomes inherently unstable. If I use a couple of mods on their own - especially the smaller ones - everything is fine. But KWRocketry, Near Future and Umbra don't seem to mix very well (which is a shame, since I really like to build self-sustaining ships, stations and bases). Usually with all these mods installed the game loads, I can build and launch rockets, but returning to the Space Center usually crashes the game back to desktop and the corresponding logfile shows "out of memory" error messages (which I guess concerns the 32 bit address space, since I got 8 GB of physical memory and KSP is using around 3 GB of that). On a similar note, if I install EVE/Astronomer's Visual Pack together with all the mods mentioned above, the game will either crash back to desktop directly after the loading screen is finished, or the game will stop on the loading screen (it won't crash though, it just stops loading the remaining mods/files). I know that EVE is not yet (?) available for KSP 0.25, but if I use EVE without any of the other mods, the game loads and runs fine. To try and fix this, I deleted all local game content in Steam, deleted the KSP folder in 'common games' manually, redownloaded KSP, redownloaded every mod, reinstalled every mod one by one and checked if they all worked (they did). But putting them all together makes the game crash constantly. Am I missing something? Or is this just the way it is and some Mods don't mix? Basically I've got more than 400 hours of playtime in KSP and I'm looking to make the end-game more difficult and more interesting by adding the need for life support (oxygen, food & water consumption, CO2 recycling and so on), therefore making the construction of (self sustaining) space stations and colonies somewhat more challenging. Also the addition of near future (theoretical) propulsions allows the construction of some interesting space craft. Anyway, while I found lots of mods that do parts of what I want there doesn't seem to be a single mod that offers the kind of mix I'm looking for (except for Kerbal Interstellar maybe, but the last time I tested that it was unstable all on its own without any additional mods). And when I'm putting all the mods together the game becomes highly unstable. I know there is probably nobody to blame for this, but it's somewhat frustrating.
