Multiple PCI root express problem

Amor96 — Wed, 22 Nov 2023 21:03:48 GMT

Hello Everyone,
I found that PC have multiple PCI ports that keep crashing my system
I encountered a lot of freezing and black screen while gaming or browsing
With a unplug/replug USB sound constantly

Tried removing them via device manager but once I restart they are still there I also tried
-"Reset this PC" option
-Installing new windows from iso image
Also with the same results

System specs
-i7 11th gen
-MB: Gigabyte Z590 vision G
Windows 11 home edition 23H2

Hello, @Amor96

Thank you for posting on the Intel® communities.

I am sorry to hear you are having trouble with your PC, I will do my best to assist you here.

Was it working before?
Were there any recent software/hardware changes that might have triggered this issue?
What is the error message of the BSOD you get? Do you have a picture?
What are the error code/messages of the PCI root devices that are failing?
Please attach the following reports to have more information about your system and test your processors' health:

Intel® Processor Diagnostic Tool

Note: Please attach the complete Screenshot or click on "File", select the "View Results File" option, save and attach the report.

Intel® System Support Utility for Windows.

Note: Make sure to mark the box that says "everything" before pressing the Scan button. After that, click on "Next>" and select "Save" and then, attach the .txt file.

Hello,

-PC was fine until last week when all these performance issue appeard

-Not at all I have this PC for over a year now nothing changed, as for softwares only windows/apps updates

-There is no bsod, system would just freeze then restart by itself

-No error codes The ports will keep dublicating tried disabling them but the are attached to some hardware (one of the ports when disabled disconnects my ssds or Ethernet driver)

Hello, @Amor96

Thank you for the information provided.

I noticed in the Intel SSU report that the memory speed is running at 3700MHz, which is outside the processor's specifications and not supported as the maximum for DDR4 memory is 3200MHz. Please lower the memory speed so the system runs within the processor's supported memory speed.

Please be aware that Altering clock frequency or voltage may damage or reduce the useful life of the processor and other system components, and may reduce system stability and performance. The memory controller is internal to the processor. When an XMP profile is used, the frequencies and possibly the voltages within the CPU are changed. Product warranties may not apply if the processor is operated beyond its specifications.

Also, please make sure to follow all the recommendations listed in the Random System Crashes on an Intel® Boxed Processor article, and run the Intel XTU tool to check the results:

Intel® Extreme Tuning Utility (Intel® XTU)

Note: Click on the "Stress Test" tab and "Start Testing" and then, attach a complete screenshot.

Hello,

When I started to have this issue I suspected that memory might have to do something with it even tho they worked fine at their full speed in last 2 years

Removing the xmp profile and setting memory to default speed 2666 MHz yet the problem still persist

Also tried removing the physical ram sticks one by one and changing their slots in the mb and no luck

As for the stress test I hope you can give more details once I press starts test there is 4 categories to choose from

I already done a mem test for 5 with the 3700mhz speed If that what you was looking for

Hello, @Amor96

Thank you for your reply.

Please do all tests to check on your processor's health, however, as mentioned above, Please lower the memory speed so the system runs within the processor's supported memory speed (3200MHz). Altering clock frequency or voltage may damage or reduce the useful life of the processor and other system components, and may reduce system stability and performance

Hello,

All test results attached here

I hope you understand this is not a hardware issue I already done multiple tests for my memory, CPU and GPU with no issues at all

Hello, @Amor96

Thank you for your reply and the reports provided.

I will investigate this issue. As soon as I have updates, I will let you know.

Hello, @Amor96

Thank you for your time.

We have done some research about this and similar issues, and it looks like an OS vs. drivers issue.

People mentioned a few topics:

C-states to be disabled,
downgrading BIOS by one or two releases,
change disk work type from AHCI to RST
Windows version issue - I've seen articles saying that Win 11 23H2 is a bit problematic and Microsoft locked update

Please request the following questions from the user:

When was the last BIOS update and from which version?
What was the last working OS version and build?
Did you touch/reseat the CPU recently?
Did you find any helpful info in the event log (export system, setup, application)?

Suggest the following Tools/tasks to help with search and diagnosis:

PowerShell commands listing devices:
- pnputil /enum-devices /class System
- (gwmi Win32_Bus -Filter 'DeviceID like "PCI%"').GetRelated('Win32_PnPEntity').GetDeviceProperties('DEVPKEY_Device_LocationInfo').deviceProperties | ft data,DeviceID
Open device manager, select View from the menu, and change it to "devices by connection" - it'll help visually find devices

Make sure to check the following:

Physically inspect the motherboard (slots, ports, disk connections), GPU, etc, - looking for any physical issues
- connect only needed equipment (for tests) -> no dGPU
Download Win10 and 11 22H2, latest OEM drivers, latest Intel drivers
Based on the commands above try to narrow down or find what is causing the issue and then do what's below:
- Load failsafe default settings in BIOS (disable core enhancements)
Install clean Win11 and do a full update using Windows Update (while having the device manager open) - if those devices are multiplying or causing issues, it may be easier to spot what and when it happens
- test this config a bit and check if the issue will appear
  - connect dGPU, then test OS with iGPU enabled/disabled
If a problem exists (test one by one):
- check C-states theory
  - Test Win10
- downgrade BIOS by 1 release
- compare existing driver with OEM and update if OEM is the latest

Best regards,

Jocelyn M.

Hello and Sorry for the late reply
I have tried almost every solution yet no luck the ports are still there, here's some detailed answers for your suggestions

1-Bios related :
-Bios is on the latest version already since it was released back in June this year
-Downgrading to 1 or more version didn't work
C-states are turned on and off (didn't work )

2-Physical inspection:
-No external attachment to the motherboard except the keyboard and mouse

3-Windows:
-reinstalling win 11 either from iso or "reset this PC option"
- downgrading to wind 10 also didn't seem to effect the drivers by any mean
-as for windows update I can unfortunately say it unreliable to count on it for fixing the problem it always suggested older drivers for my devices
-Also tried reinstalling drivers from OEM with no results
4-powershell commands :
Nothing worth noticing all devices listed with name, hardware IDs and guid
As for your suggestion to list by connection
I can see that my Ethernet,ssds,display adapter and audio under one of the PCI devices that could explain why trying to disable them will result in one or more disconnection of my other devices

5-Some suggestion I would like you to clear for me :
-For storage I don't have Hdd but 2 nvme ssd can we still switch ACHI?
-What you mean exactly by "touch/ reset CPU "
Physical removel ? If so then no I didn't since I bought the PC

Thanks in advance

Hello, @Amor96

Thank you for your time.

Could you please try or confirm the following?

Did you try creating any ticket at Gigabyte asking about the driver or other possible issues related to the motherboard? If done already, what was the response?
Have you tried a cross-test with another motherboard or CPU?

Best regards,

Jocelyn M.

Hello,
There was Nothing from gigabyte but basic troubleshooting (device manager and reinstalling windows)
-sorry don't have any spare parts to try on

Hello, @Amor96

Thank you for your time and patience on this.

Since we have tried a lot of troubleshooting and we cannot isolate the issue since there are no spare parts to test it, we recommend you contact your local Intel Customer Support for help with an RMA process:

U.S. and Canada: Intel Customer Support

Europe, Middle East, and Africa: Intel Customer Support EMEA

Asia-Pacific: Intel Customer Support APAC

Latin America: Intel Customer Support LAR

If the issue persists after replacing the processor, we suggest you contact your System Manufacturer for further investigation, as the processor would not be the cause.
