Congratulations. It shows a lot of class that you didn’t just blame the game, stuck with it and eventually found the cause of the problem.
Do you have a guide to increasing the page file size? Strange we would need that with 64gb of ram. The page file shouldn’t even be used unless you are out of physical ram.
I’d like to try to see if it will fix my CTDs.
I have 32GB RAM and increased my page file size to max 64GB after reading this was something to do to avoid CTDs. I was desperate at the time and increase the size. Not surprising, it didn’t do anything to cure my CTDs.
Reinstalling MSFS and all addons, keeping my community folder fairly clean (only add-on linking what I need for a given flight), switching RAM in their slots (cleaning contacts as well), moving my powered USB port to a different USB port… One of those things cured the CTDs. I now have my pagefile size set by windows (as it is by default) and still don’t get any CTDs.
32GB RAM (and for sure 64GB RAM!) should require a massive pagefile size.
Might try a different USB hub then. Strange that would cause the sim to crash tho.
My crashes started when I installed the Black Box Bonanza. I have since uninstalled it and reinstalled the whole game and it still CTD. So idk if there maybe a file left somewhere I deleted the whole flight sim file under app data. I did a full reinstall from scratch.
My understanding is it won’t use the page file until the system is out of ram? My page file is set to 9GB right now? What should I set it to?
For example: update microcode, update CPU microcode, improved TPM function, improved memory compatibility, support Re-size BAR function to enhance GPU performance, update Intel microcode for security vulnerabilities, security update.
No need.
All good - no CTD 
Pagefile setting should always be left to Auto regardless of RAM size.
Another issue that could be avoided just by not tinkering with the OS and for which MSFS has been blamed…

Yeah, I set mine back. No need for a massive pagefile. Did absolutely nothing to improve performance or eliminate CTDs.
Why ??
Does that blanket statement not depend on if that Pagefile is on a SSD or a rotating HD ??
Regardless of hard disk / SSD and even if you have 64 or 128 GB of RAM you shouldn’t reduce the size of or disable the page file. Applications must be free to page unused data from the RAM into that file, because they are programmed to do so and if they don’t find enough space on it, they may crash.
Moreover, page file recommended size by MS has always been larger than the RAM, never smaller.
The best thing to do is leaving it Auto, in order to avoid crashes and not occupy many GB on the disk / SSD permanently.

Disagree, but this is not the place to argue with individual forum members.
Then there is the question: Set Registry option to Delete Page file content on windows close, — or not. ??
You do your thing, I’ll d mine, and lets agree to disagree.

i have suffered the problem of this dll for many months.
In the end it was the RAM that when brought to frequencies of 3600 did not hold up.
I changed it to more “performing” RAM and I no longer had this problem

You upgraded your RAM instead of just setting yours to a lower Mhz-setting???
You know that CPU’s have maximum recommended RAM speed and that 4 sticks might be more instable at higher speeds than 2, right?

I had a Fury that had to go to 3600mhz… too bad that by setting it in the bios to 3600mhz it made this joke.
I changed it with one that holds 3600mhz without problems model G.Skill Trident Z

I have tried putting my ram at default speeds no XMP same issues.
Not true.
I would say that 2 sticks might be more unstable at higher speeds that are above the specs of the sticks. They probably are and should be.unstable.
The 4 stick issue appears to be more of an older AMD issue and probably has been resolved. idk. I use Intel.
Those that run their memory at the CPU stated speed are loosing a lot of performance and should run it at the memory specified XMP.
Or at least, buy the memory at the speed of the CPU spec if you are going to run it at that speed. Why waste the money on higher spec’d XMP memory.
Please don´t use XMP but adjust the RAM speed manually. XMP almost fried my mainboard once (CPU and RAM went incredible hot the CPU fan was running at 100% at all slight applications), and the PC kept crashing, restarted with a red RAM debug light on the mainboard. That day I thought I have fried my computer!
Setting the RAM speed manually with some slight undervolting (and even with 300MHz overclocking) worked PERFECTLY fine 
and the computer is as cool as a cucumber with CPU temps never exceeding 70°C…
Some XMP settings f… up the voltage of the CPU and RAM, better never use this function
XMP is the most stupid and worse and high-risk function that got ever implemented into an UEFI Bios 
Want to share my experience … first: I never cared about RAM, RAM Speeds and so on … just for the size of them…
I experienced very random ctd with the 0xc0000005 error code, some day none, some day 1-2 … just very unpredictable…
I came about to take a deeper look into “RAM”… i read something about “cpu and compatible ram and speed”… i own a 5800x3D and i had installed 2 RAM Sticks sold in a 2x16GB Combo (Corsair Vengance LPX DDR 4). The Ram is running with 3600Mhz on the XMP Profile…
But, the 5800X3D Specs specifies it: Max Speed @Dual Rank → DDR4-3200
Changed their speeds in the BIOS to 3200 … fine… didnt work… i uninstalled both sticks and looked at their labels…
At first sight they look identical, specs are the same… nearly the same … one is an older version with 0.01V higher Voltage (they were sold together).
I looked into the compatible ram module list of the mainboard (16 pages)… found one 2x32GB which was available at a local store and finally, no ctd since replacing the “not MSFS compatible”-RAM Sticks (they otherwise worked fine in other applications like Adobe Creatives like Photoshop or Premiere)…
MSFS is a picky beast when it comes to “RAM”…
I never thought I would ever worry about what kind of RAM to use…

Very, very wrong.
Person A
Buys 2 sticks of memory. No specs are provided.
Will need to spend 3 months trying to determine which combination of the many memory timing parameters to set in order to get these sticks to even run and then to run faster.
Person B
Buys 2 sticks of memory with a specified XMP.
The vendor states via the XMP that the memory is capable of running at the stated speed if the motherboard and CPU are capable.
By enabling the XMP in the BIOS, the timing parameters are automatically set.
If the memory runs with error, decreasing the speed in steps will find a speed that will run without error on this particular motherboard and CPU.
It is impracticable to not use the XMP unless you want to run the memory at
non XMP speed, 2133 Mhz, or whatever the default is, JADEC spec, for that memory.
Spend months/years to learn and become a memory timing expert?
I’d rather be flying.

Is this still fixed for you?
Yes, I did everything I wrote and the sim has - since then - only ONCE crashed on me. I can throw whatever there is at the sim now, it really was wrong hardware configuration on my part and most likely a too small pagefile size.
