The sim crashes when I use the «turbo-overclock-thing» in BIOS (I have the i9-9900K CPU) Will DirectX12 make any change?
DX12 won’t make an unstable overclock any more stable.

Some software titles just really hate overclocking

Which motherboard is it?
My Sim runs at 5 GhZ all core stable like a rock

What’s actually happening is that one piece of software typically pushes your hardware harder than the other programs that ran “just fine” with an unstable overclock. What that requires is tuning down the overclock a bit to make it work.
That’s the reason behind the myriad “but my overclock works fine with all my other games. MSFS is garbage because it crashes” threads and posts since the sim was launched. Yup. It does. But none of those other titles pushed hardware to its limits like MSFS does.
I can overclock my Ryzen 2700X to 4.2 GHz locked on all cores (I won the silicon lottery with this CPU). It works great for everything else I do from gaming to video rendering. But it will crash MSFS at that frequency. If I tune it down to 4.1 GHz, it runs, but I encounter stutters. If I tune it down to 4.0 GHz, I end up gaining a couple of fps and lose the stutters.
Overclocking isn’t the a “1 button and you’re done” thing. It’s a process of fine tuning over time. And most people don’t get that.

In the BIOS there is an option for «turbo boost» mode. I just activated it. Should I do anything else?

If you don’t know what you’re doing, you have 2 options;
- don’t touch anything
- educate yourself about overclocking and go for it
Plenty of resources on the web about overclocking.

FIrst, don’t use that turbo boost. There are entire forums dedicated to just overclocking. That’s how much is involved in doing it properly. The scope is well beyond what belongs in a flight sim forum.
That turbo boost is a bone Asus has thrown to the non-techies out there to give them a boost. But it won’t always work, as you’ve discovered.

As others have said leave the Turbo ■■■■ alone, watch the vid posted, it’s a good one and try overclocking properly. I have an older i7 (6700k) and after watching a few of these and getting the confidence, my CPU now runs 700mhz over stock speed and the performance increase is very noticeable, especially in built-up areas in the sim.

My best advice re clocking a 9900K CPU is… don’t!
These chips [and most modern Intel chips] are, in effect, designed and produced to run close to
their limits straight out of the factory! The result then is that any clock applied by the user can very quickly push the CPU to where it thermally does not want to go. And even if we could contrive to avoid throttling, the paltry 5% to 9% or so of ‘pay off’ is negligible to the point where it is hardly, if at all noticeable.
Long gone are the days when the careful overclock-er could routinely take his [now ancient] i7
from 2.67MHz upto 4.00MHz, a clock of a whopping and useful 50%!
So save yourself from an overly noisy gaming environment and look elsewhere for efficiencies.

Or when you could overclock your budget, $200 Celeron 300 to perform the same or better than the $1000 flagship Pentium II 450. lol

Unless your chip can do 5+ GHz all core. Then it might be worth it. Some 9900Ks are really good.
DX12 will mostly enable new features like raytracing @RiskierPigeon16, it won’t change anything with OC stability most likely
Ahhhhh. Happy days.
Taking a 9900K upto 5.1MHz is still only a tad over an 8% clock increase. This is still only marginal as far as any performance increase is concerned.
And along with all the extra cooling noise, you also get [and the data bears me out on this] a reduced
CPU lifespan! You really can’t get something for nothing, here.
Besides, the gains are also ameliorated by the fact that any given CPU is inherently hidebound by it’s own onboard cache’s and registers. This, no amount of clocking can overcome!
Interesting debate though!
Cheers.
Addendum:
DX12, on the other hand. Well…
Parallel CPU to GPU addressing.
Multi core/thread support.
Properly implemented all this can be ours. And not a clock in sight.
