Memory overclocked or defective?

Do you use sim connect? I only ask because I used sim connect to try and use project fly and simtoolkitpro and I had severe stability issues. Once removed it was fine.

Thank you … well, i really dont know … how can i check it out?
Well, there were plenty of patches in between which might have changed things under the hood e. g. for optimization purposes.
I’ve hadn’t had it myself but I’ve read numerous times now that overclocking (e. g. XMP) might be related to crashes.
It would have been something you manually installed, probably with a 3rd party application. You can see in the program manager in windows whether you have it installed. If you do, might be worth uninstalling it, to see if it resolved your issues.
When I had sim connect installed I would get consistent ctds within an hour
Thank you for your help … i just manually delete a 747 livery (American Airlines one, from latest Clinks package) … will that be a reason?

I don’t think that would cause a sim connect related crash, it’s not required for liveries. The only thing I could think of doing for troubleshooting purposes would be to empty your community folder. Move your liveries in to a temp folder, outside of the sim directories, run your sim, see if it remains stable and then try putting them back in. If you then begin to experience problems, there may be something in your liveries folders that could be causing issues.

Highly unlikely.

Outside of clearing the community folder, I’ve had a quick google and ensuring that you have the latest graphics driver installed, somebody is also talking about manually overriding the page file. I’ve never needed to do that since windows was invented but may be worth looking at as an additional troubleshooting step.
How much RAM do you have? I don’t think it’s a memory availability issue because you said it was working fine before.
Thank you guys … how about the new version of Navigraph charts? It was updated this very morning … but I was not using it upon the crashes.
16RAM working perfectly …
I don’t use that, so I can’t speak for it. But if you weren’t using it while flying it’s probably not the issue. The only question I would have is, does it integrate with the sim? If it does, then the chances are it does it through sim connect.
It uses a sim-link app so you can trace live your plane upon the charts outside the sim … gotta be!
I would try removing that, purely for troubleshooting purposes. You can put it back in if it still crashes. I could never get a stable experience with sim connect installed.
Let me know how you get on 
Thank you man! Explain to me something please … SimConnect is a removable program? It is not a MSFS function itself? Sorry bothering this much.
Yeah, it’s a separate application that you should be able to see and remove in the windows program manager.

UPDATE! First of all, thank you! … It seems the new version of Navigraph Charts was the cause, because upon unistalling it it seems Im back at stable within MSFS (i will post the issue in their forums) … I checked simconnect and im aware i was not having it, nor using it. I will be testing more today and let you all know. Thanks again!
Except it isn’t.
Simconnect is a .dll that comes with MSFS and exposes datarefs for external applications.
It had issues in the release version (caused big stutters) which have long since been fixed.
It is more than likely Navigraph rather than specifically MSFS (or simconnect)
