Hi:

You need this driver...

ftp://ftp.hp.com/pub/softpaq/sp67501-68000/sp67924.exe

[lgXenos]

Already installed )))

I'm look for AMD IOMMU Driver

Found sp67924.exe. Not help

After this found sp72321.exe. But nothing change

Maybe I'm must uninstall something before?

This story started by three unknown drivers: 2 video + iommu

Video fixed only after uninstall and install again sp72887

iommu I'm cant fixed 😞

What were reason of this errors - unknown... System stable work and active used sleep-mode

Some days ago sleep-mode turn-off.

Hi:

You probably have to manually install the driver. 

I know that is the one you need because if you look at the driver file folder contents you can see that this driver has support for the hardware ID you posted.

[AMDIOV.NTamd64]
%IOMMU.DeviceDesc%=NULL_DRIVER,PCI\VEN_1002&DEV_5A23
%IOMMU.DeviceDesc%=NULL_DRIVER,PCI\VEN_1022&DEV_1419
%IOMMU.DeviceDesc%=NULL_DRIVER,PCI\VEN_1022&DEV_1577
%IOMMU.DeviceDesc%=NULL_DRIVER,PCI\VEN_1022&DEV_1423
%IOMMU.DeviceDesc%=NULL_DRIVER,PCI\VEN_1022&DEV_1437
%IOMMU.DeviceDesc%=NULL_DRIVER,PCI\VEN_1022&DEV_1449
%IOMMU.DeviceDesc%=NULL_DRIVER,PCI\VEN_1022&DEV_1611

Sometimes the auto install file does not install the driver, so you have to outsmart the PC.

Go to the device manager and click on the IOMMU device needing the driver.

Click on the driver tab.  Click on Update Driver.

Select the Browse my computer for driver software option, and browse to the driver folder that was created when you ran the file.

That folder will be located in C:\SWSetup\sp67924.

Make sure the Include Subfolders box is checked and the driver should install.

Then reboot the PC.
