Some observations regarding 2.7.x crashes/ctds & overclocking

[The LT]

First: so far, it seems the devs have nailed most of the crashes and I have yet to see a single crash on 2.7.1.

Now, I've discovered something though:
I had to reload my uefi bios profile due to some configuration changes and I noticed my previously configured overclocking settings which were stable for 2.5.x did not work out for me on 2.7.x with random CTDs not accompanied by "game crashed" dcs dialogbox. Funnily enough, my system passed every single stress test with no lockups (occt, xtu, aida, even prime95).

 

I had to up the core voltages a bit (about +0.020-25) to stabilize the system in DCS. Whatever the devs optimized in 2.7.x obviously made DCS more sensitive to OC.

 

TL:DR: Make sure you dial down on your OC if you're crashing even if your system plays everything else just fine and passes stress tests with flying colors.

Just my 2 cents.

Thanks for your feedback.

You're right, DCS is more sensitive to undervolting than it was before: I've already helped 3 people with the same issue.

DCS isn't really CPU demanding, single core usage somewhat but overall CPU utilization will be low.

My bet is that you use adaptive voltage in your OC meaning you have all power savings active which is very hard to get right and "stable". I saw numerous PCs get through rigorous testing with linpack and prime95 just to crash on the desktop while moving mouse due to voltage dips/transients caused by power saving features.

Yup, that's right, been running adaptive for years. Funny thing is, DCS was the only app with issues. I've since upgraded to 10900X from 7900X and it has a much better power state management, I've been able to dial it down to lower core voltages and DCS is running fine.
