Hello, I am using an asus M4N68T M LE V2 motherboard and HIS HD 5670 ddr3.The graphics card is recognized as 1.1?! I googled everywhere but couldn't find my board's pci version. I think during the first boot and installation of drivers it is 2.0 and afterwards i did some overclocking. Is this because of the overclock?? Please help me.
