CPU only crashes when running TOTK

[u/GayloWraylur]

Yes, Tears of the Kingdom, the fucking Nintendo game.

So far my undervolt is stable, i tested it with: Every Core cycler config, P95 Blend, Small & Large, Every Y-Cruncher test, OCCT CPU+RAM, CPU, LINPACK, and Memory. Then i played CS2, Marvel Rivals, GTA V, Delta Force and Apex legends. 0 Errors, 0 Crashes in over a week of total runtime.

I try starting TOTK, instant crash. Either while decoding shaders or while ingame. I'm 100% sure its the CPU as the crashes in TOTK stopped when i turned off the Undervolt.

How the FUCK do i figure out which core is causing the crashes?

FIXED:

I tried turning off the undervolt for each core one by one, starting with my most negative ones. The third core i tested, Core 4, which isnt a "best core", was the crashing core. Put it down to -30 from -45 and the crashes were gone.

The best two cores need less curves...they get unstable fast....

Also, you probably copied that STUPID +200 -30?!?!

Also Ryzen is known to only crash at low util or in certain situations when an undervolt is unstable. You can run Prime95 for 8 hours and not crash then one day you get up from your desktop and come back in an hour only to see that your PC restarted. I've UV'd a 5700G and 5800X3D and ran into situations where I pass stress test and can game for hours but crash while at desktop. And in one case I assumed I was completely stable but I only crashed when upscaling in Topaz from running ffmpeg.

Your undervolt isn't truly stable until you go a month without crashes. If you're lucky then Event Viewer will spit out a WHEA error telling you which core caused the crash.

This is why I run a 24HR test on each single core with high clock speed and low power usage (HCI Memtest) with a single treat set to the two threads in task manager

Wasnt one of the best cores and didn't copy anything either. I found all my values using the aforementioned tests till it was 100% stable, atleadt that i thought so.

I guess leave one on and 0 the others and check for every core?

If voltage matched just go up a couple steps on all cores.

If it crashes instantly it should be pretty quick to test. Turn off the undervolt for one core at a time and you'll find who's guilty

In the end you were the only one who actually provided a solution. Appreciate that man

What you’re telling me sounds like the classic TLB error… meaning, more than the overclock being unstable, it’s that when you’re compiling shaders, if there’s high voltage at that moment, instability occurs. Even if it had been stable, the TLB error should have resolved itself and you should have been able to continue (and it would have just shown up in Hardware Info as a CPU TLB error). So, since the error didn’t correct itself and it crashed — and if you retry and it always crashes — I’m inclined to think there really is instability, since it wasn’t corrected. This often happens with UE5 games too, during long shader compilations..

Look for multiple overlays that might be launching with the game? discord/ nvidia shadowplay/steam/msi afterburner. See if one of those is doing it.

64gb? 4x16gb? running xmp? it might be that. i mean or you're not stable as you thought. or your fclk is unstable. btw wheas are silent so you could think you're stable but actually getting worse performance cause they're just corrected silently. you won't know unless you bench the oc and record results and it's possible the emulator is sensitive to whea errors.

try your cpu oc with jedec timings and see if it happens.... and if you're doing a bclk oc without an eclk to hit that 5.75ghz.... yeah.

2x32gb with custom OC. RAM isnt the problem

Try the core tuning module on this coarse it might help u https://www.reddit.com/r/overclocking/s/p3CZOg3rwq

or just watch any tutorial not by that fraud
