Antminer U1 - overclocking on default setting?

[melon21]

I got my first Antminer U1 running. I used BFGminer, and after some tweaking, and trying cgminer, i finally got it running. I just got this one to see how it works.

My question is right now i have one Antminer running, and I set it for the default clock speed of 1.6 Gh/s.

However, the clock is running at 2.10 Gh/s (through BFGminer), even though I have it set at 0781. Anyone else experience this? I am just going to leave it like this, but was wondering why this could happen.

bat file is something like this:

“bfgminer.exe -S antminer:all –set-device=antminer:clock=x0781 -o URL:PORT -O worker:password”

I believe these are the other options:

1.6GH/s - 0781 (DEFAULT)

1.8GH/s - 0881

2.0GH/s - 0981

2.2GH/s - 0A81
