Anyone have luck with the -straps function?

-straps Memory strap level (Nvidia cards 10x0 series only). The possible values are 0 to 6. 0 is the default value and uses the default
     timings from the VBIOS. Each strap level corresponds to a predefined combination of memory timings (-vmt1, -vmt2,
     -vmt3, -vmr). Strap level 3 is the fastest predefined level and may not work on most cards, 1 is the slowest (but still faster than
     the default timings). Strap levels 4 to 6 are the same as 1 to 3 but with less aggressive refresh rates (i.e. lower "-vmr" values).

I'm getting an error 31 Must be run as administrator...Tried to do so but still getting the error...Wanted to see if this feature could be used instead of the ethlrgmentpl
