What does 13900k instability look like

so with enforce all limits on, at stock on r23 it’s throttle the core down to 5100.
With the tuning guide, I cannot get it down to a stable level by just reducing acll as it either runs up to 100 degrees or crashes. Is there any other methods I could use or have I just been unlucky in the silicone lottery?

Does your board give an SP rating?? Global, P & E cores?? Mine for example Global 103, p 111 & e 88, also does it show the VID table?? Can you post a screenshot
 
Hi - will post a screenshot of that tomorrow - nearly bedtime for me

Tonight I’ve fitted a thermal take cpu support. Temps have now dropped 8 degrees c on full load and I can run without mobo limits on r23, stable with acll at 0.24. Max p core temp is 96 deg and no throttling at all of the cores - all p core at 5.5 solid and e cores at 4.3 solid.
My score has also gone from 38760 to 39953!

Not bad for a 12 quid bracket. Will now follow the guide and see if I can get that acll down lower then follow it through

Not the best temps there bud. Either not very good CPU or your cooling isn't up to the task

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.

Here is a great guide, says for beginners but it goes into too much detail and can confuse, best to read and test as you go.

Thought I’d give this guide a go today. Maybe you can shed some light. Everything’s going swimmingly until he explains to select adaptive voltage and enter 1.480v and decrease until instability. It’s making 0 difference. I’m not getting any instability at all. Got to be something simple I’m missing?

yeah mine did the same, never asked him why.

The best way to test Adaptive voltage is to run Geek Bench 5 which benchmarks the full V/F curve voltage spectrum as it lowers the low load voltages. CB23 will not show an adaptive voltage instability. If you can get to 1.44V adaptive and your target die sense for full load (done via DL_LL / AC_LL) remains the same you'll be good to go. If not and your at AC_LL 0.01 you'll need to alter the V/F curve using the octool which will generate a v/f curve offset to lower the target die sense for full load while maintaining the correct low load voltages.

That’s the thing. I’ve tried everything and it’s as if it’s completely ignoring the “Additional Turbo Mode Cpu Core Voltage”.

If you set adaptive back to auto you should see the idle voltages higher. With the adaptive voltage they lower it. For example I set 60x per core for 1 or 2 cores, my idle voltages shot up to 1.52. With adaptive voltage set to 1.45 they reduced to about 1.48V.

If the adaptive voltage is set below the V/F curves factory set voltages, it will ignore your adaptive voltage setting

That makes sense. Thought I’d give this a go just to test against an All Core I’d already set. I’ve found Geekbench and Realbench to be the best to test for instability. I could get all the way down to to the minimum AC LL 0.01 in Cinebench R23, but found I had to increase to 0.07 after further testing using Realbench. I’m not one for Prime 95, but found Realbench to be the happy medium.

If I’m being honest, I much prefer the old way of setting a manual voltage, sync all cores, but it’s good to learn a new way of doing things if nothing else, and having a play around.

what I did notice also was that I can’t increase the CPU Cache Ratio at all using this adaptive guide, anything past 45 is unstable. Don’t have that problem using the manual voltage.

If you're doing an all core OC you won't need Adaptive voltage as you won't be seeing really high idle voltages unless you can do an all core over 5.8. It's only when you are doing a per core OC adaptive voltage is needed. If you do plan on keeping an all core oc, a manual voltage will be the way to go.

Thanks for the info, especially the adaptive voltages being ignored due to them being lower than the VF curve, I thought I was going nuts haha.

You'll ideally want adaptive for all core so you idle at low voltage and power draw. C states don't work with fixed voltage. I personally don't see a reason to run fixed voltage and higher idle draw for normal usage but each his own.

Easy adaptive on asus:
- find your fixed vcore and llc post stability testing
- flip to adaptive and use 20mv lower
- now goto Internal CPU power management
- Set AC AI = 0.01
- Leave DC AI = auto
- Turn on cstates under advanced, cpu configuration, power management at the bottom, enable cstates
- Stability test again. Adjust your minimum voltage in adaptive and fixed line up. No need to pump more volts than necessary. Use TurboV to adjust voltages in OS so you don't have to reboot to make changes

cant remember which TurboV version i have but it aint stable, sometimes applying can cause system to crash and lock up, somethings not right with it. And occasionally changing voltages drops the clocks 100hz
