This is the first time I've ever seen it, so somewhat curious. Any time I've gone to crack a password I've only had the option of 1X, this time it gave me some message about how I could use my hardware to overload it and I was able to use 2x, which took the crack from .1 to .133, does this have a chance of damaging my hardware?
It should not damage your hardware. It is limited within your hardware. But I dont know, Im only guessing.
