this is wrong thinking… your PC works within the normal specs and you not use overcloacking.
I use kind of overcloacking and have no issues, because I not created weakpoints which make the system instable.
And additional you are far aways from “a half” with these settings you mentioned 
.. like a ant from the moon… but you have a stable system which can run days without a crash.
Actually not. I have CTD every day. But it’s variable some day 1 CTD, some day 5 CTD. But i don’t have CTD in other games. It’s important! Think about it.
I don’t even want to argue with you about overclocking, because you don’t even understand what it is. For you, any increase in frequency is overclocking.
if you say it 
Will add an extra fan then (indeed with some help haha). I hope in the meantime Nvidia can do something about the problem via a software update.
Happy holidays Micha!
Dear MichaMMA
Thank you, my comments:
2)I play in 1440p
PSU is AX 750i, not an issue.
Works fine with downgraded memory, with all memory BIOS on auto (-100 on 3DMARK) but not a deal breaker. Will report back once the new patch comes out to see if I can reach 3466 Mhz again
You are 100% correct. That is an important point. Name me one other game that has multiple cloud based process engines doing everything from converting and processing weather data, duplicating real world aircraft flightplans, processing photogrammetry from a planet load of satellite images to managing a streaming network through a multitude of servers around the world.
MSFS is not your average multiplayer first person shooter. Sure there are cutting edge games out there with amazing graphics but when comparing the load on your system, they are simulating an etch-a-sketch.
@MichaMMA is doing you a service here. keep plugging away at it. Once the system is solid tracing other CTD sources is greatly simplified. You can bet that if there is a bug in the code that is causing it Asobo is working hard to find it, but even if the solve their bug, you will still be having CTD if your system isn’t smoothed out. The loss of a couple fps over an entire afternoon of flying is better, I think, than screaming fps for 5 minutes 'til CTD.
FYI
Hi @DCOLUH,
yeah,.. I not know your experiance or your pc system therefore I often ask issue-reporters about it. But, in your case I just not noticed that you already wrote about your pc-case 
Have in mind what I wrote here is never meant in a bad way
What I meant with 4h in full load was, that not each game I own/know hold your system full-time near 100%. Most games give your hardware time to relax a bit..
As for these reason I set often (not always) for longer flights ( where I just enjoy the view and “play bit with the garmins” ) the vsync setting to e.g. 30.. so my 2080ti can relax a bit by with my near 4k resolution ( 25fps because vsync bug vs. ~50fps in full-load is a huge diff ).
It is strange that your system can not manage to work at least with 2666 setting. I know, some mainboards have issues if all fours memory-slots are used or with high-freq RAM in general, but it is a new board. I simple assume that 2666 works fine… ( note: in internet there are some sides about the asus z490-e and ram :-/ ).
But yes, the impact of RAM speed to performane is not the highest one ( different than the manufacturers would have us believe )… I assume you can get from 2666 to 3466 5-10fps more, with luck… but higher prio is stable work.
I hope you are right and MSFS have realy implemented an own strange memory-‘handler’ which have a strange dependency to memory timings and a patch can fix that. But this would be, a bit strange…
Let us know.. today is update day
And for all users which overcloack or using XMP mode, etc. and feel sometime restricted I would like repeat:
I will not say XMP mode is worst, or overcloacking is worst. But a bit experiance is necessary and if trouble occurs the first thing to do is to bring back your system to a default state which is realy ensured stable and this means no overcloacking ( and xmp is nothing else ).
Only then we can search the reason for the CTD in windows, drivers or the game it-self ( and there exist some well know reasons for CTD ).
Dear MichaMMA
No worries, your points were valid.
I just installed the new patch, flight in the background has been going strong for 2 hours now.
wait and see…
I am just waiting for the RTX 3080 to be back in stock and activate the two new monitors I offered myself for Xmas.

Never had any issues until after updating to 1.12.13.0 now the game immediately crashes to desktop when using “flight planner” on the main screen and hitting “fly/launch” also tried a landing challenge and all was good for about 5 minutes then it too crashed to desktop.
Tried clearing out my community folder as well as a fresh install and it’s still happening.
Sadly I’m having CTD issues again. Before this update I hadn’t had a CTD in a while. I’m going to try downclocking the GPU a bit and seeing if that works. I had a 150MHz overlock prior to the update and it was working well for over a month. So frustrating.
Man this sucks! I had no issues since the last update. CTD again!! No error. How are you suppose to figure this out whiteout errors and why so many issues after an update??? The sim freezes after loading from the planner for 4 seconds and then CTD.
At (KJFK) landed ILS Rwy 31L - landed and simulator CTD, no error message. Reloaded the simulator, started out at (KJFK) instead of flying there, I didn’t start my aircraft, move it or anything! I wanted to fly around in the drone cam just to check things out and it says my aircraft has ran into an object, every - single - time . . . what in the F! This is annoying man. I gave MSFS $100 for garbage. All just so you could give us VR for a broken simulator? Fix this other garbage before you release anything new for the simulator. I can promise the developers this. The simulator WILL LOSE ITS POPULARITY if the bugs continue.
I’m not sure if I should post here or create my own thread but I’m having CTD issues now with no error messages, no nothing.
I have the steam version and for a while I had a random CTD with no error but it was very random. And as long as I was able to start a flight I had no issues in-game. The issues would happen after I got to the main menu and would randomly happen when either on the world map, or when loading up. I never had error messages when in the options menu or main menu itself. But now the game doesn’t even load at all. When I click “play” on steam it acts like it’s loading but then just crashes.
Here’s my system specs:
OS: Windows 10 Pro 64 bit
CPU: AMD Ryzen 7 2700x
RAM: 2x16GB Corsair Vengeance RGB Pro (at 2933mhz but is rated 3200)
Motherboard: TUF Gaming x570 Plus
Graphics: Nvidia 1060GTX (6GB)
Storage: Western Digital Black SN750 nvme (500GB, main os and flight sim installed on it)
Samsung 870 QVO SSD (1 TB, other games and “community” folder)
Seagate 1TB (backup, non SSD)

I just got a CTD, after last update. every time that they update the sim I don´t expect anything good!
Same here, devil is back!
Yea- unfortunately it’s really difficult to stay on board. I too feel dread every time they release an update. If it re-introduces an issue it’s going to be a rather long wait until they fix things again (if they’re even aware of issues).
I’m going to do a longer test flight with my GPU clock reduced and see if that works. Still will be disappointing to dial back the clock since it runs 3DMark, Cyberpunk, and a lot of other games very very well with those settings.
I was just going to mention the newest update DOES NOT like my GPU being overclocked even the slightest bit as it’ll CTD even trying to launch a flight. At stock speeds game runs perfectly fine. Weird thing is I’ve NEVER had this issue until the newest update.
For the first time, I am now getting CTDs after the recent update. I can’t find any reason for it, it just happens suddenly during flight. RAM tests fine, all other games playing perfectly.
What does the event viewer show?
.. and I will direct comment your created issue thread !!
