Signal processing controller 8086:a77d

[Marcin_Szczurowski]

Hi,

I found this intel device on my system after swapping i7-12700KF for i7-13700K.

Signal processing controller -> Intel Corporation Device [8086:a77d]

If I have to guess, this have something to do with graphics but I don't know. Most of all, driver for that thing doesn't exist as far as I know.

What is that and where do I look for Win 10 driver?

It looks like Linux kernel have it.

Best,
Marcin.

In English it would be something like "Signal processing and gathering PCI controller"

I believe it's iGPU related, as I can't get 3D to work properly.

Device ID: 8086:a77d

You didn't include any information about your motherboard, so I cannot link you directly to the file, but I believe that you need to reinstall the Chipset Device Software (a.k.a. INF Update) package that your motherboard manufacturer provided on their website. Use the following process:

1. Download the Chipset Device Software package from your motherboard manufacturer. It will be a ZIP file.
2. Extract this package to a temporary folder.
3. Open a Command or PowerShell Window as Administrator.
4. Change directory (CD) to this temporary folder.
5. Run command ".\SetupChipset.exe /overall".
6. Reboot.
7. Delete temporary folder.

Hope this helps,

I reinstalled same version of the chipset driver and it worked. I'll never understand why this happens.

Thank you!

Then I won't waste a lot of time explaining it. It was caused by your processor change.
