KabyLake PCI Express Root Port # 10 - A2B1 drivers not working

[OMotu]

Hello,

So this problem still persist - KabyLake PCI Express Root Port # 10 - A2B1 drivers not working. Saw many post, nobody have a sollution.

my cpu - intel i5-7600k

my motherboard - msi z270 pc mate.

Yes i have latest bios(v16), yes i reinstalled chipset drivers after i updated bios. Obviously there is three parties that might be at fault, Windows 10, motherboard or cpu. We simple humans don't which is it. I think this problem stayed to long and to many people are affected by it to just ignore it for you guys. We want sollution. Please.

with respect,

intel cpu user

Hello OviMot,

Thank you for contacting the Intel community. After further review, this is an issue that it is related with your motherboard chipset, I can see that the latest chipset driver version from your computer manufacturer is 10.1.1.38, you can try the latest generic version from the Intel site, you can download it here:https://downloadcenter.intel.com/download/20775/Intel-Chipset-Device-Software-INF-Update-Utility-?product=98089 Intel® Chipset Device Software (INF Update Utility) Also, run Windows® update and make sure you have the latest updates installed. I hope this can help. Regards, Ivan U.

Hello Ivan U.

Thank you for replying. Windows updates is up to date and i installed drivers from your recommended link and its up to date too. 0.1.1.42 is newest now.

Root port # 10 still not working. There is one thing that got my attention though, in the device manager i found chipset familly devices and the port that is not working.

So when i opened chipset controller and went to drivers tab, i saw that drivers is still 10.1.1.38.

Then i did the same with broken root port # 10 and the driver version is 10.1.1.7

It says windows cannot load any drivers error code 31.

I hope this information helps and we can find something to beat this problems.

Thank you for your time.

Try uninstalling the driver and then reinstall the new version, if it does not work you we will need to wait for a new driver to be release via Windows update, through the download center or from your motherboard manufacturer, basically your motherboard manufacturer should be more familiar with this since they integrate your motherboard, chipset and BIOS.

Hello again,

Maxboz - i don't think it's fixed, it's just older windows do not detect this problem.

Esteban C - So i contacted MSI (my motherboard dealer) and they said there is no fix for now, and that msi and Intel will need to find fix for this, and when there will be a fix they will contact me. Can you at least tell me how does this problem affects my CPU?

Hello OviMot,

Thank you for the answer provided.The tool or driver could affect PCIe behavior, have you faced any sort of problem relatd to a PCI device?Also, I found the following article with has some recommendations while installing the chipset driver.Steps to be followed:

• Download the driver again: http://intel.ly/2u3pe5f http://intel.ly/2u3pe5f
• Press Windows key + R to get the "run" window
• Drag and drop the SetupChipset.exe file there and leave a space
• Then enter "-overall" command
• Install the driver
• Restart the system when finished
• Check the error again
