Once you reach a clock that's over what CCC can reach (885) it will stop reading. From what I can see that's normal. That doesn't mean your clocks are screwed up.
As far as your memory. Every card is different, but you'll probably get some better memory clocks as well with better cooling. With the stock cooler I was hitting in the 80's load, with the V2 I'm getting in the low 40's load. That extra heat has to affect the memory clock as well. At least a little.
