Sometimes,also, with a lower overclock setting and lower hashrate you will get a higher Utility.

Care to explain how that works?

No,I can't explain how that works, but, ckolivas posted a suggestion a while back.

He said that once you find your max GPU Engine clock that your card runs stable at try to drop your GPU clock 5Mhz at a time to see if there's a sweet spot where your Utility increases. I tried that and I did find a spot where my Utility went up a little at a lower GPU Clock.

Maybe ckolivas could elaborate on that?
YMMV,

I did not ever say that. I said there are certain engine/memory clock combinations where the hashrate rises more than linearly with engine clock speed with the unorthodox kernels like phatk. Utility is hashrate * random luck and it should just be linearly related to hashrate.

I think this is the post I was referring to.

When I was doing this I did find a spot where my Utility increased and obviously my hashrate increased too. Funny how the minds eye works sometimes
