Z790 hero whea 17

I know some z690 boards had WHEA 17 errors and I just noticed that I started to get them every 20-30 ish minutes or so. Has anyone else encountered this on the z790 boards?

A corrected hardware error has occurred.

Component: PCI Express Root Port
Error Source: Advanced Error Reporting (PCI Express)

Primary Bus:Device:Function: 0x0:0x1C:0x1
Secondary Bus:Device:Function: 0x0:0x0:0x0
Primary Device Name:PCI\VEN_8086&DEV_7A39&SUBSYS_88821043&REV_11
Secondary Device Name:

Can't seem to find a lookup for :PCI\VEN_8086&DEV_7A39&SUBSYS_88821043&REV_11 yet unless someone knows which slot it exactly is.

I got them on a 690 Hero after a fresh installation of Win 11 Pro. I know it's a different motherboard, but you might get an idea from the following:

I installed all of the Win 11 drivers manually and couldn't understand why I was getting 2-3 WHEA 17 errors every second.

After a couple of days, I did another fresh install and let Arnoury Crate install the drivers - all was good after that. Then I just updated drivers where newer ones were available. Don't know if one of my manually installed drivers got corrupted, but maybe this information might help?

Here's another clue, I later discovered that an external NVME drive had got corrupted (and would have been corrupted when I got those errors). It worked, but was reporting the wrong amount of used space (disk properties vs checking folder sizes manually) and was running at slow file transfer speeds. I still got the WHEA errors even when it wasn't plugged in so maybe not, but you could check your drives for errors as well. You never know...

I can't say if those events were linked or not, but since the reinstall using Armoury Crate and reformatting the external drive, I haven't had another WHEA 17 error since. I suppose it's possible (but probably unlikely) that the external drive corrupted a file in Windows somehow.

PS I couldn't track down the exact source of the errors either, but like yours, they were related to the PCI bus.

Hi guys,

On Z690 motherboards, to stop the WHEA errors, in the bios disable PCIe Native Power Management.

This might work for your Z90 motherboard.

I actually updated to the 0088 bios and everything seems fine for now. In case it happens again, do I also need to turn off Link State Power Management in the desktop or will the bios already cover that? Thanks!

I really don't know, but pleased that everything is working after a BIOS update. I think you can safely enable/disable link power management and see what effect it has. Please let us know what happens if you want to try that. Thanks.
