Problematic defaults for the SA Fabric ration on the 285K

[NumberEngineer]

I don't know what got into me to try the default value. It breaks everything.

I had to set the values inside the BIOS.

Did I input the right value, can you (intel) fix this issue of default value, if I crash, the system tries to reload them, it's terrifying.

Hi NumberEngineer,

Thanks for posting in the community. I have some questions about your current situation. Can you answer the following questions?

1. I see that the active values are different from the default values. Have you tried loading the default settings for your processor?
2. Can you tell me what you are trying to achieve by changing the voltage value of your processor? Are you perhaps trying to overclock it?
3. Have you tried going into your BIOS and loading the default settings?
4. What issues are you currently experiencing with your system?

Best regards,

1-Yes, the default of 63 consistently crash my computer

2-use it, at all.

3-there is no default for these value on the bios

4-it wont boot

my current solution is to manually set the NGU ratio and voltage on my bios.

but whenever i do some mild overclock using intel XTU, if it fails, it force set this fabric ratio to default.. which is 63??!

As seen in this screenshot, the value is a lie. it is not running at this speed.

It's running at a ratio of 26 as shown in HWiNFO.

Please fix this, I sometime get stuck in failing boot loops. 

I use the latest microcode 0x114

Hello NumberEngineer,

Thank you for answering those questions. I still need a bit more information. Based on your current answer, it seems you have tried to mildly overclock your system. Did you previously attempt to overclock or underclock your processor? Please note that if the system was overclocked, including voltage/frequency beyond the processor's supported specifications, it may void your processor's warranty.

Additionally, could you provide the exact make and model of your motherboard? If I'm not mistaken, there should be a "Load Defaults" button in the BIOS. Pressing this button will revert all changes in the BIOS to their default settings. Could you try looking for it and using it?

Also, for random crashing how about try doing the following troubleshooting below:

• Try to load the default BIOS setting in your system, or update the BIOS. Refer to the motherboard manufacturer for support with BIOS updates.
• Update Windows*. Select Start > Settings > Windows Update.
• Check for overheating issues. Make sure the thermal solution is compatible and installed properly. Refer to troubleshooting overheating issues.
• Start the system in minimal configuration. Minimal configuration: motherboard, processor, power supply unit, and one DRAM module.
• Check the power supply to ensure it is suitable for your self-built system.
• Check for memory issues:
  • Try to have a sufficient amount of memory in your build system.
  • Try different memory sticks.
  • Make sure the memory is seated well.
• Try another motherboard if possible.
• Run CPU stress test for Windows* and Linux*.
  • For Windows use the Intel Processor Diagnostic Tool and run Burn-in Test.
  • For Linux, look up available stress tests for Linux.
• Try to get a fresh image of the operating system.

Let me know what will be the outcome of doing this troubleshooting.

I understand and agree with the warranty conditions about overclocking.

First off.

My system is currently stable.
It use the default XMP for the ram.
It uses the default clock speeds.

I have attempted the bios reset to default.

(edit bellow)

which causes the issue to resurface. 

only after manually setting the NGU ratio manually to 26 in the BIOS that my computer will load.

my motherboard is 

MAG Z890 TOMAHAWK WIFI

Dhanniel,

None of your suggestions are relevant to what the person describes.

In the Intel Extreme Tuning Utility, the SA Fabric Ratio defaults to 63x.

Why?  Can you please answer why the default is 63x when the ratio for NGU is shown as 26x in HWInfo?

NumberEngineer - you can shutoff and unplug the computer, then do a CMOS reset. Plug in and start it up and you will get to the default BIOS.  Save your BIOS profiles, so that you can quickly reload when it occurs again.

I believe the SA Fabric Ratio is showing 63x instead of the 26x. The Help in the Intel Extreme Tuning Utility is not showing or detailing instructions for these parameters. Values above 26x need VCCSA voltages increased, which may be why it crashes the Intel Extreme Tuning Utility profile.

I have a Gigabyte Aorus Master z890 and have the same issue.

Hello NumberEngineer,

I understand. Let me investigate this further on my end to find a better solution. Thank you for pointing this out, @kmaleski. I will make sure to take note of this information.

Hello NumberEngineer,

Thank you for your patience. I have a few questions for you. Please answer the following:

1. What is the default SA Fabric ratio setting in BIOS.
2. Can you confirm if you did not make any manual changes to SA Fabric ratio setting in BIOS.
3. Can you identify any SA Fabric settings visually disabled in BIOS?
4. Have you perform BIOS reset or motherboard factory setting reset and check what default value is in BIOS for SA Fabric ratio?
5. Is your Windows OS is currently updated?

Best regards,

Hi Dhanniel,

The XTU software has a bug where it will display the value of 63x for the SA Fabric Ratio WHEN the ratio is at its default of 26x in the BIOS.

Please talk to your software engineers.

1) We told you the default was 26x

2) It is defaulted, so of course the user did not make changes

3) The SA fabric mode is grayed out

4) We told you the default was 26x

5) Yes

None of your questions are relevant to what the person describes. The XTU has a bug.

Please talk to your software engineers before replying.

Hello NumberEngineer,

I just wanted to check if you have seen my previous question about this concern. Also, @kmaleski thanks for sharing your answer to this matter, and I will be waiting for @NumberEngineer answer as well. If you have the further concern with the same issue I would highly suggest to create a separate thread for this one. This way we can make things more organize in answering, reassured that an Intel representative will answer you inquiry. 

Additionally, I appreciate the diligence in reporting and identifying this matter. Currently our XTU team has successfully replicated the issue as you described. Please rest assured that our team is aware with this issue now and, actively investigating potential solutions to address this discrepancy. Also, Intel is currently working with ODMs to isolate the issue ang get it fix. As w are committed to ensuring that our software provides clear and reliable information.

Best regards,

Woohoo
Good news. I will look forward the fix.

1-default is non existent in the BIOS
2-no
3-no
4-yes, non existent
5-yes

Once XTU fix the 63x, further issue will be handled with the motherboard manufacturer

[laulau]

yes you have to leave the parameter at 26
moreover what crashes on asus ROG STRIX Z890-F GAMING WIFI
with bios 1302
it is the extreme parameter you have to leave performance.
with that you can do as you want with xtu for the frequency of the p cores within the limit of x54 to x56
plus a temperature limit of 95° in the bios.

[laulau]

The xut configuration is very poorly done, still no Intel recommended profiles to import like the 13900k at the time
even the ROG STRIX Z890-F GAMING WIFI 1302 bios are not super good, no default anti-voltage protection, no
default normal boot voltage.
We have to try everything ourselves.

[laulau]

if they are not able to make an xtu profile for each cpu to download it is not worth it.

[NumberEngineer]

Lol i think there is a loss in translation.
I saw your french message.

I would believe they have a profile for each processor. How else would they configure it for release

[kmaleski]

Agree.

I also agree that the motherboard manufacturers have some poor defaults set, and it is a bit of a bug hunt to find what has to be switched on or not to get what you want. The XTU - ignoring the bug in this thread - simplifies overclocking with a better UI than the Bios.

I recommend Skatterbencher to read up on what does what https://skatterbencher.com/  with regards to overclocking these chips.

The only issue is that it is quite difficult in some cases identifying the differences in nomenclature between ASUS and our motherboards.

[DhannielM_Intel]

Hello NumberEngineer,

Thanks for providing this information to me, and since our XTU team is currently investigating and working with the ODM's to provide potential solutions about this discrepancy. I will now be closing this inquiry. If you need further assistance, please submit a new question, as this thread will no longer be monitored.

Hi Dhanniel,

The defaulting of the SA fabric Ratio to 63 instead of what has been set in bios has been fixed in this last XTU release.

Thank you.

BUT

The SA Fabric Voltage does not correspond to what has been set in BIOS. It is unclear if that is because the list of voltages is limited.

Please have your engineers look into.

Thanks,
