Been pouring over this for hours.

I am positive that I solved it. I have had multiple hour(s) long flights thus far where I was only going about 10 min before the silent CTD.

It was my XMP profile in my BIOS settings. I purchased this memory for my new system: Patriot Viper Steel Series DDR4 4400MHz Performance Memory Kit - PVS416G440C9K (x2) for 32 gig total running XMP 2 profile. This is on a MSI MEG ACE Z390 mainboard.

XMP 1 runs at 4394MHz and XMP 2 runs at 4264MHz. My system was unstable for most uses at XMP 1 and even at XMP 2 - which I had been running seemed *mostly* stable. Ghost Recon was also randomly crashing and it was driving me nuts. This change also fixes that issue as well.

So, I throttled this memory down to *3866 MHz* with the built in BIOS / SPD profile and ran Prime95 for a few hours. No crashes. Hopeful, I loaded up MS FS 2020, 45 min in and it was solid as a rock.

Note: I had OC on my 2080 TI and my i7-9700K proc turned off, BT disabled and gimped all my settings, turned AI traffic off, etc.

Once I got a few hour(s) flights completed, then I started to re-add all the other things. I used MSI Dragon Center to go "Extreme Performance" mode OC for my processor i7-9700K" and still solid. Then ASUS GPU Tweak to run my ASUS Strix ROG 2080 TI at an "OC Mode" and still solid, then re-enabled BT. Still good. Went all settings to Ultra, AI traffic, live wx - all good!

So, in summary, memory XMP profile was too much for my system and had to run my memory at a slower clock but still higher then average memory speeds for this platform.

I know that this may not work for you. I got the idea in the MSFS 2020 CTD thread. It was the one thing I haven't tried.

I am happy!

Awesome information thank you for sharing it.  Most of the time I find CTD come down to two things either faulty drivers or something up with the memory. I tend not to overclock my memory because it always seems to cause more issues then it helps.
