PCI Express version 1.0A and 1.1

[tomoharika]

Hi. I am a new commer for  the PCIe systems. 
I attached a PCIe board installed a PCI bridge PEX8112-AA to my Windows 7 PC. 
Although I believe PEX8112-AA is a PCI Express version 1.0A, HWiNFO shows it is version 1.1 .
How come?? 
I wonder that HWiNFO show the PCIe Express version 1.0A as version 1.1 ???

You're right, this is not guaranteed to be correct because I'm not aware of any software mechanism that would allow to distinguish PCI Express 1.0a / 1.1 compliance. So HWiNFO shows v1.1. also for 1.0a.

Thank you for your quick reply.
You mean from the upper software, PCI Express version 1.0a and version 1.1 look the same, it can not be distinguished.
So, the upper software do not worry about the difference.
Thank you for your support!

Yes, something like that..
