Daily OC on i7 13700k became unstable after BIOS update

Level 8

Hi everyone. At the end of February I tweaked a small OC to my i7 13700k. Just 55x to p-cores and 44x to e-cores. Also I enabled xmp 1 profile and did a small undervolt with -0.01V on adaptive voltage. Everything was stable and I could rerun Cinebench r23 again and again. After BIOS update the same settings became unstable and Cinebench keep crashing just on the start of multicore test. Few days ago I updated BIOS to the newest version 0904 and still the same thing. Could somebody answer me what could be a possible reason?
My setup:
Cpu: i7 13700k
Motherboard: asus rog strix z790-f wifi
Ram: G.Skill DDR5 32GB (2x16GB) 6000 Mhz Trident Z5 RGB Black (F5-6000J3636F16GX2-TZ5RK)

Hello,

any particular reason you’ve not applied AI OC? You can check the CPU SP score and predicative voltage for adaptive under AI Tweaker, along with your ideal per core usage settings.

LLC6 is going to be too much for an undelidded CPU on ambient. Follow the AI predictions and set level 3 to 4.

The rules for AI OC are quite tight this gen, so there’s often not much reason to deviate from these predictive settings on ambient.

Hi.

I tried AI OC but it's too unstable for stress test like Cinebench but probably will be ok for daily use. Or I think in wrong way 

Your cooler score should give some indication, I think you're thermally constrained for one reason or another. Personally have found the contact frame to be beneficial in this regard. No issues with memory OC (if correctly torqued) as per specs in my sig. If happy at stock, of course no reason to explore the idea.

I like the idea of AI OC and I will try it of course. But I feel that prediction of 55x on heavy load with predicted voltage wouldn't be enough for running Cinebench stable as I tried before

Again, thermals and cooling solution will hold you back here also. The AI rules can only skew so much if thermal headroom is too tight. Cinebench is a high current synthetic workload, you may want to focus on tasks you intend to use the machine for and work from there.

You mean that I don't have to worry too much about being stable in Cinebench and just focus on usual workloads?

Yes that's correct, this is actually a good idea and a good way to avoid those high temps.

After running the AI Overclocking, when you boot up, it will flash a screen and show a percentage of how much it was able to overclock. 

Instead of running cinebench, Open Hwinfo, play a game and see if your pc is stable. When finished, check the maximum temp.  

Temps should be much better than with cinebench.

I tried AI and what I've got. During indexing files in project and while compiling it, temps were around 60-70 due to high cpu load. In games I think I won't get temps higher than 70 in the worst case scenario. So now I have some kind of choice. Leave 54x sync all cores with lower temps and even stability in Cinebench or use AI OC and have little bit higher performance in daily usage but instability in some stress tests

Try with the AI Overclock for a while and see how things go.

You don't necessarily have to run a stress test. If you get errors in HWinfo, blue screens or freezing,  then it's time to investigate.

This is personal preference, but anything below 80c, I consider acceptable temps. Max temp of 70c is perfectly fine.

You can see individual core clocks and core temps by clicking the small arrows to the left, you can also show all values by clicking the blue arrows at the bottom left of HWinfo.

Thanks, I really appreciate it
