We have a HP Z820 workstation that displays this error multiple times every day: "928 fatal PCIe error".
We've already updated the BIOS to 3.91 Rev.A but it hasn't solved the problem.
We've also tried downgrading the BIOS to 3.88 Rev.A (sp71580.exe) but at the end of the flashing process it gives an error and won't finish. Also tried to do this via USB stick, in the BIOS, but no success.
Is it possible to downgrade the BIOS of a HP Z820? If it's possible, then how?
