Thanks for joining the desktop community.
It would be very helpful if you could include system specifications:
* Desktop Board:
* Board Altered Assembly Number (AA#):
* Board Serial Number (SN#):
* Previous BIOS:
* Current BIOS:
* Power Supply:
* Operating System:
The details I could find are -
* Desktop Board: Gigabyte Z87-HD3
* Board Altered Assembly Number (AA#): ?
* Board Serial Number (SN#): ?
* Previous BIOS: F6
* Current BIOS: F7 01/20/2014
* Power Supply: 750 Watt
* Processor: Intel Core i5 4570
* Memory: 16GB
* Operating System: Windows 7 64-bit
* HDD: 64GB OCZ-AGIL AGILITY3 SSD
To be be honest Allan it's not an issue with the system, I think Windows is getting the readings from the DSDT ACPI table written by an Intel engineer that is why I am posting here.
I was just wondering if I could speak with someone about why it is displayed like that in Device Manager?
Basically it looks like the PAM register memory address ranges (e.g. 0xD0000 - 0xD3FFF) are shown to be on the PCI bus, but the ranges from 0xFED00000 onwards aren't shown to be on the PCI bus, when I think they are just like the PAM registers.
Again it's not an issue and there maybe a reason for displaying them like this but I would just like to know what it is.
for example I had a look on another Intel system (I'm not sure of any details) and it showed the following -
It shows that from 0xF0000000 - 0xFFFFFFFF to be on the PCI bus, which I think it should show on mine, maybe this is an error in the DSDT table, or maybe it is like that for a reason?
Sorry for the delayed answer.
Since your computer is Gigabyte and all the components were integrated by your motherboard maker, you need to check with Gigabyte engineer about this matter, or contact Microsoft for more information on this issue.
If you would like to contact an Intel engineer this has to be through an Intel authorized distributor and work with field application engineers
Here is a list of Intel authorized distributors:
