Oops. My Motherboard is : Manufacturer: Gigabyte Technology Co., Ltd. Product Name: Z68XP-UD3R It is so odd that Corei7 Can't support it.

You said that your CPU is the i7 2600K and posted this link to the Ark: http://ark.intel.com/products/52214/Intel-Core-i7-2600K-Processor-8M-Cache-up-to-3_80-GHz It clearly states that it has no VT-d, thus you are not able to activate the IOMMU because there is no IOMMU. Your steps were all more or less the correct way to activate it, but your hardware does sadly not support ist. The point is that Intel normally deactivates VT-d for the -k-versions. If you compare it to the i7-2600 (http://ark.intel.com/de/products/52213/Intel-Core-i7-2600-Processor-8M-Cache-up-to-3_80-GHz), you see that this CPU would support it. Please note that your Chipset/Motherboard/BIOS needs to support VT-d/IOMMU, too.
