Z790-H + i7 14700KF + Luiqid Freezer 3 360 - throtling on stock

[Pix2186PL]

Hallo Asus community,

I've got problem (like allmost all user of 13 th and 14 th gen Intel processors) that on stock settings processor throtle duo high temperatures. Now for some details:

- new system build by me (not the first time) - Asus z790-h, i7 14700KF, Liquid Freezer 3 360 (fans are pulling out air from case), Kingston (2x 16 GB) ddr 5 6000 mhz CL 32, be quiete Straight Power 12 1000W, case asus GT520 + 5 arctic fans (3 at bottom to suck air, one at the back to remove air and one in the middle), asus tuf rtx 4070 super

- motherboard fully updated to bios 2301  (just notice that o 12/07 there is a new one 2402)

- bios on mainly stock settings (only XMP 1 activated for memory, all fan curve on standard and Asus MultiCore Enhancement [Disabled - Enforce All Limits] )

- Arctic Liquid Freezer 3 installed with added contact frame and allready 2 time repasted with Thermal Grizzly Kryonaut to be 100% sure that there are no problems with heat dissipation. Cooler is connected by cable that allow to control separate fans on vrm, cpu and pump since when it was connected with the combo one i've got feeling that they didn't work in 100%. Pump header connected to CPU_OPT, fan to CPU_FAN and vrm to CASE_FAN

- Windows 11 pro fully updated and to read temperatures in system i've use aida64, hwinfo, intel xtu. To test system stability and load i'm using Cinebench 24

- all temperatures that i'm showing here are on cpu package so the hotes spot

So now in idle i've got somphing like 40 C - nothing to woried about since there is very hot outside and we got only one simple fan in home so not the best conditions. After 10 min Cinebench i've got somphing like 1900 points and hwinfo show 96C+ with thermal throtle (i would say that most of people got same results or the same even on aio 240.

Anyway i've try to first change SVID Behavior from auto to somphing else and notice that auto is probably setting "Intel Fail Save" since after picking it manualy i've got same vcore in hwinfo under load with is 1.480V+. On "worst-case scenario" vcore is lower 1.450V but still same thermals result and same cinebench points. Trying "typical" scenario ended with lower vcore 1.350V and not thermalthrotle (somphing like 80C-85C max temperatures) but in cinebench i've got like 1000 pointa and i can feel the lack of power even if clock are the same as the previous settings.

The second try to solve problem is to add vcore negative offset to lower that creaz power and since svid behavior on typical was too low (every next like "base case scenario" is lowering vcore even lower and that couse same low cinebench point) so i've started from leaving it to "worst case scenario and applying core voltage offset in XTU (need to turn off voltage protection in bios and turn off wirtualization so that software can work). Anyway for now even with - 0.0800 i dont have any lower temperatures. System is stable and cinebench is generating same 1900 points (more or less but still its not 1000).

For now i dont know if the direction that i'm following is ok since i can try to lower and lower that offset but still there schould be some more easy way for every user to get this to work in normal way.

If someone got any ideas of how to lower this temperatures without losing performance please write.

Hi @Pix2186PL , maybe https://www.youtube.com/watch?v=tcjkNSySzsg video can help you control the power draw and the temperature while maintaining the performance.

You can also checkout https://rog-forum.asus.com/t5/technologies-explained/memory-kits-overclocking-and-what-you-may-not-k... post about memory overclocking once you have set your CPU to an overclocked but stable state.

I hope this helps you make progress.

Hi @achugh 

Thanks for interest in this topic - the video that You send show mainly where i need to put value that @Silent_Scone  write below so i'm gonna use that to check if that work and of course i'm gonna watch that video and try to undertand how to set up everything (in web there is a lot more tutorials and guide mainly for i9 since they got way more problems then i7 and i5 and this video is allso fot that procesor but i assume that everything is base on same settings but diferent values).

About that RAM settings topic - are You sugesting that the XPM profile could be the source of problem - if i didnt activate it and leave the defoult value will temps be lower?

Anyway if You got some tutorials that are aimed for i7 then let me know - i will try to add that limits and post here the results.

Hi @Pix2186PL I totally understand. Yes, Silent_Scone is much more knowledgeable with regards to any form of overclocking so please continue to follow his advice.

Hi @Pix2186PL 

Typical SVID Behaviour will result in a more optimistic ACLL. Cinebench is a heavy all-core workload and hence pulls considerable amounts of current compared to most tasks. I wouldn't be overly concerned with those temperatures unless they occur during lighter workloads.

Alternatively, limit the current limits under Internal CPU Power Management and set ICC Max to 307A and PL1/PL2 to 253w. This should bring temperature more inline with your cooling solutions capability.

Hi @Silent_Scone 

Many thanks for reply. Today i've decide to update bios to lates version 2402 since in note there was info "Updated with microcode 0x125 to ensure eTVB operates within Intel specifications" so i assume that this could resolve my problems. Update done, biose settings ware loaded to defoult so again i've set up XMP I, disable undervoltage protection and wirtualizacion for future usage of XTU and rest was leaved as defoult (OC profile was Intel Default Settings so same didn't touch it).

Running Cinebench 24 didnt show any changes unfortunately:

In that case You suggest to go in bios under Internal CPU Power Management and set ICC Max to 307A and PL1/PL2 to 253w and that schould do the work? Any more changes that i schould do or be aware to change (for example if on defoult settings everything is allmost on auto schould i set up somphing on manual to be able to modify that values? Some screenshot would be very nice if possible 🙂

Hi @Silent_Scone 

Setting manual ICC Max to 307A and PL1/PL2 to 253w didnt help - no changes in termal at all and when i apply changes the grayed value from the auto setting was exacly the same. Any others sugestions?

[Pix2186PL]

Additionaly please write me why @Silent_Scone  PL1 schould be set to 253W when on official Intel page there is recomendet value of 125W:

 i7 14700KF is 8P+12E Core 125W - only units with 16E on extreme profile got that value recomended.

[Silent_Scone]

Feel free to limit PL1 to 125w to follow Intel's new recommendation more closely, and retest performance. Alternatively, flash to the latest UEFI 2402 to enable Intel base performance profile by default.

[Pix2186PL]

Allready did that (settings limit on PL1) and it wasn't good experiance 😛 PC act like i5 10 th gen - mayby it was just single startup of pc but after that i've stoped testing and get back to 253w.  Updating Bios (and by defoult intel base perfomrnace profile was activated) also didnt provide any diferent in thermals.

Yesterday evening i've done some test on that manual limits PL1/PL2/ICC Max and playing Cyberpunk ended with max temperatures of 92C without throtle, on Diablo 4 temps was even lower but it's a bit less demanding game but funny was that in the middle of updating Diablo 4 before starting game pc throtle duo a lot of operations that procesor did during instalation....

On reddit i've contact some guy that posted information that on similar configuration he got exacly same problem but he manage to solve it - so i've ask him to send his bios config:

• XMP: XMP I (XMP II that I was running turned out to be the cause of random crashes)

• Fast boot: DISABLED

• SVID Behavior - Worst case scenario

• Intel ABO: AUTO

• MCE: disabled - enforce all limits

• LLC: Level 3

• IE CEP and SA CEP - AUTO (=DISABLED)

• ICC Unlimited Current Max - DISABLED

• PL1 and PL2 253

• ICC MAX: 307

• CStates, Enhanced C-states, Package C State limit: Enabled, Enabled and AUTO respectively

• offset: -0.045

• TVB, eTVB, TVB Volt opt: ENABLED, and TVB at +1 (meaning all pCores at 56 with 2 at 57 when temp allows it, which is 99% of the times in gaming.

I will test it today and see how it go but on first view i can see that LLC level is 3 and i've got by defoult 3
