first: 1162/1825 is crazy high and could possibly melt your house down.
second: no pic, so it likely never happened.
It's crazy high, but not out of the realm of possibility. I ran my toxics at 1150/1800 for a while when they were 2-3 to a rig. That's about 810KH/s ea. I have 5 to a rig now, and I have to keep them down clocked because of the heat they throw off. Still getting 783KH/s each, and that's undervolted.

That said, 880KH/s ain't gonna happen unless you've got some ungodly kernel, and mint GPUs.
