10900K won't TB past 4.9 GHz, eventhough it's super cool

Hey there,

 

I've had Asus Maximus XII Formula, and I ran her on BiOS v. 0403 and 0606, but I've had this issue, of not being able to pass the 4.9 GHz Threshold on my 10900K with all settings set to Auto.

 

Now I have Asus Maximus XII Extreme, and I still have the same issue. It's strating to run me nuts. I mean I'm able to achieve all core 4.9 GHz easily with up to ~ 70°C, but when my PC idles and I load only 1 - 2 cores, it's always 4.9 GHz and all other cores run at 0.8 GHz.

 

Please tell me, is my CPU faulty?

 

These are some videos of how my CPU acts.

 

I tried clean install, no drivers, drivers, auto drivers, asus drivers, nothing. Still the same frequencies. I also tried Ai Overclock, I managed to get overvolted 5.1 GHz all core and some nasty temperatures [around 80 - 85°C].

 

In general what I want is to know that my CPU isn't defunct, I'd like to see it show at least for a blip 5.3 GHz on "auto" on single core/thread load :/

 

Please help and advise

 

With kind regards

 

Bryan

Re: 10900K won't TB past 4.9 GHz, eventhough it's super cool

Here's my take on this: You started a single-core load - but you are running other applications to monitor things and Windows is running all sorts of tasks in the background. In order to see a single-core boost to the maximum, you need only that core running. Bottom line, I don't see your experiment as being a valid away to try and see this.

Re: 10900K won't TB past 4.9 GHz, eventhough it's super cool

Hey there @n.scott.pearson​ !

 

Thank You kindly for You reply and allow me to elaborate.

 

So, this situation occurs even when I have loaded only 1 - 2 cores out of 10. So all cores are running at 0.8 GHz [in HWInfo 64] and the one or two cores are still ticking at 4.9 GHz :/. My point being, at the old 9900K, I've seen the 5.0 GHz boost clock to kick in from time to time, now I don't.

 

And second one, do You have any way on how to load ONLY the 1 - 2 cores? E.g. artifically disable the others?

 

Thank You and I stay with regards

Re: 10900K won't TB past 4.9 GHz, eventhough it's super cool

A little update, and what I found out.

 

When I manually set each core clock/ratio and set amount of cores that can go with this setting, the threshold is 7 cores. 6 cores won't do the trick, all cores no matter how many are active will stay stuck on lowest set frequency, e.g. 4.9 Ghz, or whatever i set there [even the 5.3 GHz, if set].

 

When I set 7 cores, I see 5.3 GHz jumping pretty often in light threaded loads, when I set 8 cores, that's pretty much all I see. Temps are good, vCore not so great, all is set on auto, works better with SViD set to Inte's Fail Safe.

 

So, when I want to see 5.3 GHz boost, I need to set it to 7 - 8 cores, instead of 2, like the default. By default setting, the max. I saw was 5.0 Ghz for a microscopic blip of a second.

 

I hope that Asus will fix this in time, it seems like an issue of BiOS.

 

With kind regards

Re: 10900K won't TB past 4.9 GHz, eventhough it's super cool

Have you checked to see if they provide a place in BIOS Setup that allows you to configure the multipliers to be used for one Core active, two Cores active, etc.? This is what you want...

Re: 10900K won't TB past 4.9 GHz, eventhough it's super cool

Hey there @n.scott.pearson I did, and as I said, when I "force" Turbo Boost to 7 - 8 cores to 5.3 GHz, I have them, but "default" is 2 cores, 3 for 5.1 GHz, and 5 for 5 GHz and more for 4.9 GHz. This setting doesn't work, like at all. But from what I've seen on geekbench, many people have this same issue, with this CPU, I mean like all of them, besides maybe two? [probably manually overclocked]. They have the same score as I do. TBH, I'm on the 4th place in the world atm with "default" stock settings at this moment.

 

This is something with either Intel, or Asus, but I've seen it on other motherboards, here, take a look.

 

It seems like it's still in beta, not final :/ [UEFi/BiOS].

Re: 10900K won't TB past 4.9 GHz, eventhough it's super cool

If you force Turbo Boost by loading in clock multipliers that are too high, you will have issues for sure. You may see power throttling, you may see TB refusing to boost because of temperatures, etc.

Yeah, about that...that would be a no for high multipliers, power throttling, or temperatures.

Hey there Andrew

 

Well, yes? I have two 10900K and TB isn't working on neither. It's not resolved.

 

With kind regards

Re: 10900K won't TB past 4.9 GHz, eventhough it's super cool

Hello BryanFury

Thank you for your response.

 

We understand that you have some concerns regarding Intel® Turbo Boost Technology and also we noticed you are wondering if the processors are faulty.

 

In order to assist you with this, we would like you to run some tests and reports in order to check this further. Please kindly follow these steps:

 

1- Please load BIOS defaults and undo any overclocking setting or any setting that manipulated/changed processor frequency and/or voltage either in the BIOS or through software. Then confirm Intel® Turbo Boost is enabled in BIOS depending upon motherboard capabilities.

 

2- Run the Intel® Processor Identification Utility - Windows* Version. Click on File > Save to save the report.

 

3- Please provide an Intel® Processor Diagnostic Tool report. To save the .txt report, once the test is done, click on File > View Results File.

 

4- Please perform a CPU stress test using Intel® Extreme Tuning Utility (Intel® XTU). During the test, please keep the Windows® Task Manager showing the "Performance tab". Please take some screenshots during the test making sure they capture both tools, for instance, side by side. Please let us know if you notice any throttling behavior.

 

5- Please provide Cooling Solution/Fan brand and model:

 

6- Computer Case/Chassis brand and model:

 

 

Also, please run the Intel® System Support Utility (Intel® SSU) to gather more details about your system.

 

1- Download the Intel® SSU and save the application on your computer.

https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-

 

2- Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".

 

3- To save your scan, click Next and click Save.

 

Please include all the files and reports into a .zip file and attach it to this thread. To attach a file, you must click the “Attach” option on the bottom left-hand corner of the response box.

 

Note:

Maximum turbo frequency indicates the highest possible frequency achievable when conditions allow the processor to enter turbo mode. There are different factors that have an impact on the achievable speed, for instance, processor temperature, type of workload, active cores, power consumption, environment, platform design, etc. Good system integration and thermal design are crucial to get the benefits of Intel Turbo Boost Technology.

 

Due to varying power characteristics, some parts with Intel® Turbo Boost Technology may not achieve maximum turbo frequencies when running heavy workloads and/or using multiple cores concurrently. Processors with the same model number running under the same operating conditions may see some frequency or power variance.

Re: 10900K won't TB past 4.9 GHz, eventhough it's super cool

Hey there @AndrewG_Intel

 

I've gotten my hands on some info regarding the settings for UEFi/BiOS in order to achieve "standard" frequencies, also, I purchased another 10900K for Z490I-Gaming and that one works okay on that mobo, so I'm gonna research this a bit further, and will update the thread by the end of this week [Saturday/Sunday], so bear with me please.

 

Thank You

 

With kind regards

Re: 10900K won't TB past 4.9 GHz, eventhough it's super cool

Hey there Andrew

So I have the solution. Solution is, that Asus is c*appy company, that's the solution. XII Formula, XII Extreme, Z490I-Gaming, all have some super issues with 10900K.

I just tried Gigabyte Z490I-Gaming and voila, everything works as it should.

Asus isn't what it used to be

Thank You for Your assistance, You can close this thread. Problem is buggy Asus UEFi/BiOS CPU profiles, or something.

With kind regards
