Question EDP OTHER throttling saga continues - 11900K

This is my story from the thread https://forums.tomshardware.com/thr...ench-2024-result-multi-core-seems-ok.3845242/ continued...

With the help of @uWebb429 I managed to set my 11900K more or less correctly. But EDP throttling didn't let me sleep at night... :) I decided to look for a decent board with a better VRM to solve the current issues. I got hold of Asus ROG STRIX B560-E board. It has 8+4 CPU power (compared to 8 pin on my prior board) and 14+2 phases. Suppose that should be enough.

What I started with was loading Optimized Defaults - all possible throtling everywhere - THERMAL, V MAX, EDP OTHER etc.

I lowered AC Load Line to 0.1 and set LL calibration to Level 4. Cinebench wouldn't finish the test. So I went Level 5 and it worked. Then I set DC LL to 0.1 to match AC LL, but I noticed higher temps and power usage:

AC LL 0.1 / DC LL Auto (1.1) / LLC Level 5 - 201W avg power and 1.25V avg voltage

AC LL 0.1 / DC LL 0.1 / LLC Level 5 - 225W avg power and 1.39V avg voltage

I enabled "Sync ACDC Loadline with VRM Loadline" and went as low as AC LL 0.01 keeping DC LL on Auto. Power usage went down to avg 195W and the voltage to average 1.24V. Yet still I have EDP throttling all the time. I increased CPU Current Capability in BIOS to 170% and it didn't help. Any idea what I could do next?

My last Cinebench run is here:
https://pastebin.com/6wVLLZUW

Average power: 195 W
Max power: 214 W
Average voltage 1.24 V
Max voltage: 1.30 V
Max temp: 88 C
Average frequency: 5.02 GHz

How it is possible that it's still throttling?!

That board might be better than the one you previously had but it still might not be good enough to get maximum performance out of an 11900K. The Z490 and Z590 boards are a step up in price for a reason. For comparison, my 10850K can run at over 300W on my Asus Z490 motherboard. There is zero EDP throttling at this level. The CPU only thermal throttles when it reaches 100°C which is what it should do at that temperature. Your motherboard seems limited to about 195W long term after the voltage regulators heat up.

In ThrottleStop I will assume that IccMax for both the core and the cache are set to the max, 255.75. In the TPL window you can try setting Power Limit 4 to a value of 0. You can also try setting this to the max, 1023. I think either value will accomplish the same thing.

I guess you have hit the wall. Buying a more capable motherboard with the Z590 or Z490 chipset is definitely not going to be money well spent.

I looked through Z590 boards and are there either bad ones that are at decent prices or good ones that are at unacceptable prices :).
So, I found this very nice guide on setting everything for 13th & 14th gen, but it is very handy for 11th as well: https://www.reddit.com/r/intel/comments/1eebdid/1314th_gen_intel_baseline_can_still_degrade_cpu/

So finally my changest to default settings are:
Intel Adaptive Boost Technology: [Auto] -> [Enabled]
CPU Load-line Calibration [Auto] - [Level 5]
IA AC Load Line: [Auto] -> [0.01]
IA DC Load Line: [Auto] -> [0.38]
CPU Core Voltage Override [Auto] -> [Offset Mode] -> [-0.010]

This didn't change a thing, but at least I feel my system is perfectly tuned xD.

Cinebench 2024 results:
Multi-core: 904
Single-core: 103

I guess I'll leave it this way and enjoy using it instead of running benchmarks all the time :).
