Hi guys, recently I've been having some issues with my pc where I am seeing a few WHEA 17 errors in Event Viewer. They seem to be random, and I haven't experienced any other issues with stability etc, but I just wanted to see if anyone knew what might be causing it. The only thing I can think of is that I have a -0.05v offset on the v/f curve, to help with cpu temps, which I've had for ~6 months with no stability problems at all, but I guess it could be that.

I have the latest BIOS and have updated the chipset and Intel ME Drivers

The error points to PCIE Root Port 5 which in device manager has the thunderbolt controller and a USB Root Hub under it. 

Any help is appreciated

Thanks 🙂

Hello,

1. Ensure you have the latest Chipset drivers, serial IO and Management Engine drivers & firmware.

2. Update to the latest UEFI.

3. Remove any overclocking including XMP.

4. If using a PCIE riser cable, try removing if the issue persists.

If not using a riser cable and all the aforementioned suggestions are done and up to date disabling Native ASPM should be sufficient

You can also try the following:

Disable PCI Express Native Power Management in BIOS (advanced tab, platform misc configuration)
Disable Native ASPM (Active State Power Management) (advanced tab, platform misc configuration)
Check that power savings in Link State Power Management in Windows (Edit Power Plan/ Advanced settings/ PCI Express/ Link State Power Management) is not set to maximum. Moderate should be OK.
Try running Command prompt in admin mode and then doing a "sfc /scannow". Then do "DISM.exe /Online /Cleanup-image /Restorehealth"

Those things have worked for a lot of people.

Thanks for the replies guys, I'll give these a try and see what happens. Thanks 🙂

Hello, This is Thunderbolt problem. I update bios to 2602 and intel ME, and is much worse with Thunderbolt. I have problem with Thunderbolt earlier, but now is much worse.

Interesting. Thanks for the information 🙂 I’m guessing you haven’t figured out a way to fix it?

Update:

Today I got another WHEA 17, from a different PCI Root Port (460D). This time all my monitors went black and my GPU fans went to 100% and I had to reboot to fix the problem. I still haven't gotten round to disabling ASPM so it could be that, I'll disable it tonight and see if it happens again.

Well unfortunately after over a week since changing the BIOS settings and updating to the latest BIOS, the same problem mentioned above just happened to me again. I am not really sure what to do next.

[JohnAb]

have you tried BIOS defaults for starters? If that's stable, then try the changes you want one at a time and check for a few days between each change. Might take a while, but you might be able to identify the cause that way...

Also try a complete power off at the PSU and remove the battery. Leave for 10 minutes, put the battery back in and turn back on. See if that helps at all. If not, I've heard that re-flashing the BIOS (same version) can also be worth a try. At least these things are quick and easy, even if they don't help.
