Strange Bus Interface in Gpu-Z

[hashan24]

Hello. Sorry for my very bad english. I am owner of Radeon HD4850 and P7H55-M Pro motherboard. My Gpu-Z sometimes change Bus Interface value from PCI-E 2.0x16@x16 2.0 to PCI-E 2.0x0. Also sometime change just to "PCI Express" text or PCI E 2.0x20. All those values change when i have window with gpu-z opened. Im using latest version 0.5.7. This is my Motherboard/slot or software issue ? I disabled power saving for PCI-Express in Windows 7.

If it doesn't show in using your computer then don't worry about it.
It shows my PCI-e 2.0 x4 slot as a PCI-e 1.1 x4 slot in GPU-Z.
It also sometimes shows just AMD K10 for the processor in CPU-Z.

alot of times some things are off, only worry about it if you notice it affecting your computer.
