You’ll note, as well, that your graphics card comes overclocked by default. It may be having a ram issue on board. See if you can turn the overclocking off on the graphics card and see if that helps. I know you paid extra for it, but that could be an issue.

Hi. one question.
I have a pc i9-12900ks, I only play VR. Would an RTX 4090 suit me? Would I no longer have stutters on the ground? thank you
That’s a difficult one to answer as it’s all very subjective - this is slighly off topic, buit whatever. 
I have a 13900K and a RTX 4090, I fly in a HP Reverb G2 around London and New York and it’s completely smooth on the ground and in the air. However I fly with motion reprojection enabled and I get around 45 native frames which is doubled by the reprojection. Artifacting is minimal, not noticable 90% of the time.
If you have a higher end VR or don’t like reprojection or the reprojection on your VR device is poor, then even an RTX 4090 will not be enough for a completely smooth experience!
But all things being equal my RTX 4090 provides game changing performance in VR. I still spent a day or 2 setting things up as I wanted (I’m implying that some optimisation is still necessary), in mostly ultra settings but I’ve not chased settings since and I’ve been completely satisfied with my VR simming performance.
thanks for your quick response. I have pico 4 and I don’t know if I’m going to remove the ground stutters. It is the doubt that I have. Because if I change from 3080 to 4090 it is because of the stuttering on the ground

Right, well I seem to remember VR Flight Sim Guy saying the Pico 4 does require a bit of hardward to make it perform great, but a 3080 is a great card also. I think you’ll be pleased with a 4090 though as it’s quite a bit generation on generation quicker than the old 3090 and you have a 3080.
I would say go for it, I’m sure you’ll get rid of the sutters and the Pico has such a good display it will all be worth it! 
Thank you, yes I think it needs strength to get performance. So here in Barcelona it’s 2 am in the morning, time to sleep. While I think with the 4090

I don’t have near the specs as the OP but I absolutely had an issue with blue screens on overclocking the video card. Nothing else would blue screen on the system except MSFS. A frame or 2 wasn’t worth it so I run default clock and have no issue. Just throwing it out there.

Take the 4090 without thinking it too much. The next generation cards are going to take longer to come. I also have a 12900ks and upgraded from a 3080Ti. That card is good but becomes overloaded quite frequently and has not so much VRAM. 4090 is able to keep high FPS in demanding scenarios. The problem on ground is a different history. It´s the main thread being overloaded. I had 45 fps on ground even with with my old system with SU12, until AAU2 ruined it. Now I have 30 fps. Let´s see if SU13 fixes what AAU2 broke. In that case we will have a great CPU+GPU combo.

My setup is Amd and doesn’t have Xmp. Expo is my option, but currently (bios screen) my target Dram is set to 4800mhz, not 5200mhz. It’s set on Auto

I´m not familiar with Expo, sorry. But I would leave it at 4800MHz as proposed by the auto setting. The difference in speed is so low that isn´t worth the unstability problems you have at 5200MHz. You will see no real benefit in game by increasing speed just so few.
Cheers
I’ve done what was advised,removed Armoury crate, checked the Ram on bios (currently set at auto and running at 4800mhz). Tried removing the GPU boost (bios), but that only takes me to Auto. Set the bios to optimal defaults. Tried the sim again and CTDs upon loading a flight.
I appreciate all advise, but we have been unsuccessful.
I’ll check with Asus today if the ram is compatible, but I’m sure it is according their list.
Other than that. Only option is to send components back for testing and see if there is an issue with them.
Current gen AM5 motherboards can be an extremely finicky animal. On my system, I tried to use the “supposedly” best ram for it (G.Skill Neo 6000 Expo) and it would not work properly. Not even booting with default settings if I used dual channel. Bought and tried 2 kits (2 x 32gb) with same result, so I sent them back for a refund.
Currently stable with DOCP on Kingston Fury white CL32 6000 but had to dial it back to 5800 for stability. But it’s working now solidly with all 4 slots used (4 x 16gb). Both kits are on the QVL list so I guess my point is that the even if they are on the list, there is more to it than only that. Really not sure what. It’s CPU dependent as well and perhaps the same CPU if you are lucky (or unlucky, depending what way you look at it) can have varying chance of actually working.

@GAZA350 To clarify a point: you’ve mentioned CTDs and BSODs. Do I take it that MSFS always CTDs and you don’t get blue screens when running MSFS, or do you have both? You also mentioned that Windows 11 blue-screens; is this always the case? And when does it happen, during boot or after boot, at a specific point or randomly?
Here’s the thing. The OS does not generally blue screen in the absence of a hardware problem. Almost never. Even if using particular software seems to result in the BSOD, it’s almost always hardware that’s the underlying problem.
For Microsoft to advise you to just stick with Windows 10, effectively throwing their hands up and saying ‘oh well, guess it’s just a thing that happens’ is irresponsible and suggests you were dealing with largely clueless support people who can only offer options from a script. It should not be the case that modern hardware simply doesn’t work with Windows 11. You might prefer Windows 10 (though in a couple of years you won’t really have a choice) but IMHO you should be running Windows 11, and in due course, Windows 12. Everyone should.
To suggest a diagnostic test you could do: try removing your GPU completely, connect a monitor to the iGPU connector on the motherboard, boot and try running MSFS. Obviously the iGPU would be useless for actually running the sim, but if you could get it to start a flight without CTDing that would tell you something useful.
One thing you haven’t mentioned so far that I can see - what PSU are you using? A Ryzen 9 + 4090 combo is going to draw a lot of power. If you don’t quite have enough to deal with peak demand it could cause CTDs or even BSODs. Also, the 12V cables for the 4090 can be a cause of problems if you’re using a splitter cable. I bought a PSU-to-12V cable and the Cablemod 90-degree adapter to solve my issues there.

I have an Asus mobo, use Armoury Crate all the time – zero issue. The sim plays just fine on Windows 11.
My Specs: i9-13900k, 32gb DD5, 4090, Windows 11

I was getting frequent blue screens, MSFS CTD (or my PC would just suddenly shut off), and failed AMD driver updates for a long time. (DDU didn’t help) I was running Windows 11 Pro, upgraded from Windows 10 Pro. I finally broke down and did a full, fresh, clean install of Windows 11. I haven’t had a single CTD, blue screen, or driver issue since. I didn’t change any hardware. Sometimes it’s something deep within the software I guess.

not sure if you came across this post. same error message your having
also when your ran DDU, did you boot into safe mode and run the program?

event viewer–system. you can also right click on system and select filter current log and choose critical, warning and error.
Morning, so the CTDs on MSFS when starting a flight only and no BSOD running MSFS. I only get BSOD with windows 11 installed, so that’s removed and I run on windows 10 with no BSOD.
The BSODs are random. Either on boot or randomly doing a task.
I had window 11 on the old setup with no issues. I didn’t mind using windows 11 and the sim ran fine on windows 11 with the old setup.
Yes, microsoft techs haven’t really done much, with one tech telling me 64gb ram is too much??
As for the PSU it’s a corsair 1000w. This was recommended by a few (scan, ccl ect). It’s recommended for the GPU that I run 3 individual power cords. So the one supplied obviously connects to the GPU the 3 other branches each have a power lead.
Everything is running as stock with just a standard windows 10 platform.
