What does 13900k instability look like

Harshell123 said:
Can you not lower your AC-LL at all? Your temps are higher than what I’d expect. Is your aio set to run at 100% in these stress tests, as well as your fans being set properly etc? Are your idle temps good? What’s your SP number?

Could just be extremely unlucky I guess, but I doubt it. Somethings not right.

You are going to have to upload screenshots of HWINFO etc to be able to see what’s going on.

Thanks - which screen specifically do you need to see in hwinfo?
 
Your temps are a bit high, In the same menu as the AC/DC settings is an option for setting max voltage, IVR voltage limit or something like and set to 1500mv. Run test again. And work down. Or try lowering A/C setting some more.

I wouldn’t be happy with the voltages being that high even when not under load. Your temps aren’t even that bad. What are they like in gaming? You should be able to get your full load voltages lower than that at 5.5 also.

If it were me I’d forget about 6ghz, set everything at stock and run stock 5.5 P Core, 4.3 E Core, and work your AC/LL down as much as you can until unstable then increase 2, enable C States, LLC level 4.

Then take it from there if there is any wiggle room.

show vcore and effective clocks. you've kinda expanded things not really that important. We don't know if the dc is setup properly yet.

Your core effective clocks show 5.5. This means whatever you were doing during that time windows hwinfo was open, maxed out the Pcores at 5.5.

I’ll load up tomorrow am in dcs and post the load numbers after

What does your 13900k run at?
It seems to overvolt when not under load. But when under load it anchors itself down?

Mine can get in the 80’s while stress testing.

If you have set your LLC at level 4, that’s exactly what should happen. Under load your VCore will drop, whilst low load/idle it will go up.

It would be good to see your actual V Core also.

Running r23

Here’s r23 after a few mins:

You’re basically running stock frequency there but pumping a lot of voltage.

Having your vcore shooting upto 1.5+ isn’t going to be good for chip longevity.

I’m not sure what advice you’re getting but you need to find your static vcore and llc first before messing with adaptive.

So hardset something like 55/43/49 and then start at 1.25v llc6 and work the voltages down increments of 10mv (0.010v) until unstable. Then you got a baseline to start from.

Thanks for the reply: Advice I got was following the guide I posted earlier on in this post - this one:

www.overclock.net www.overclock.net

Can you explain the 55/43/49 a bit more please and also with the voltages do you suggest using the voltage offset to put a negative in?

I did notice from the beginning that this chip seems to want a higher vcore than that quoted in the 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.

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.
