What does 13900k instability look like

[Deleted member 258511]

55x Pcore
43x Ecore
49x Ring/Cache

Hard set those in the bios. Then run fixed/static vcore and LLC6.

You need to know what your chip is stable at before messing around with V/F curves and offsets. His guide is way too complex and I'd personally never recommend it to anyone but each his own.

He stated that was the guide he was following. I personally don’t like that guide either and certainly wouldn’t call it a “beginner guide”

Your uncore ratio is hitting 5.5 also. Follow that guide from the very start where it explains to set everything stock and set LLC 4, DC LL 1.02, AC LL 0.2. I remove all limits but you can enforce if you want. Increase short duration and long duration power limits etc. Run cinebench and look at the max V Core under load. Now go and start reducing AC LL from 0.2 to 0.18 and test. If you pass without issues drop it down to 0.16 and test again. Keep doing this until you find an instability then increase the AC LL from whatever it is at when instability is found to 2 above.

If you can show a screenshot again of HWINFO.

Did you set your Uncore ratio at 55 or did you leave it auto? Set it at 45 for now until the voltage is under control. That isn’t helping.

Cheers - I did this to start with - did the guide to the letter. Could only get ac ll stability at 0.24. It’d pass r23 but failed on geekbench at 0.22.
A few said geekbench shouldn’t be an issue when reducing ac ll so am I missing something?

I’ll reset everything to standard and try again. Will post the monitoring also - bit late tonight

That’s a good idea. Just incase something has been entered in wrong by accident.

So put all back to standard with the very warm temps below! Then applied llc4, 1.02 dcll and initially 0.20acll but had to bump up to 0.22 acll to get stable.



Here’s mine at 0.22 stable. Vcore has come down a lot.


What would your advice be on next steps and really appreciate the help!

That’s much better. What’s your CPU Cache Ratio set at? It’s under Ring Down Bin.

My next step would be to reduce the AC LL if you were following that guide. However it seems like you have had to increase yours slightly to get stable so that’s not going to happen unfortunately.

Your temps and Vcore are much more acceptable though so we are getting somewhere.

Thanks mate.
It’s set to auto and here’s the cooler and predict chip performance.
