Hi guys, I just got my PE4C v3.0 today. Plugged my Zotac GTX670, on my Thinkpad T410s(win 7 pro 64bit) with AD-2 power supply using express card. And it all worked like a charm! However when i checked the bandwidth throught gpuz it shows PCI-Express x1 v1,1.. My processor is i5-520m. So i supposed i can get at least x1 v1,1Opt..i really need that compression things.Lol How do i enable optimus? Or it is impossible with my current processor? I used latest nvidia desktop driver (v353.30) Sorry im new here. Hope you can help with this, Just run 3dmark06 Fire Strike and get like only 2357. while 3dmark11 only 3150. I suppose can get way higher than this. By the way, i already disabled the hdmi sound to clear more bandwidth. Thanks in advance. Regards, Eki
