Basically what they are saying is that vdroop is not a problem - its deliberate, and that the vcore you set in bios is a MAXIMUM allowable vcore, not the TARGET vcore. If you enable loadline calibration then you risk overvolting your CPU without even realising it. Read the article and it all makes sens

I presume its any implimentation of vdroop control not just asus loadline calibration that it refers to. However, i used it on my DFI P35 with no problem.
