i think got some POS stake

and to the guy earlier who asked about the TC tweaking..
i am a bit late to the game when it comes to mining on x11 and x13 algo's
but i noticed you will often have far lower memory usage (dedicated) on your gpu for those algo's
why i don't know maybe a cgminer implementation issue..i have not looked at the sgminer code
but i have on cudaminer and as soon as i use settings too high for cudaminer the ram usage drop like a rock
even though it may look like it's hashing at far faster speeds..
So TC being tied to the ram usage seems to be in my experience a scrypt or scypt-n thing..
But i just what i said earlier as my rough method of setting up sgminer for all algo's.
I mean if that is is high as it can go then well yeah then that is it lol
quality not quantity when hashing.. if you see 1 HW error CHANGE your settings..
from my experience that means your pushing it too far and you will almost certainly benefit from lowering your settings.
pushing it too far will give more errors and lower the submitted shares and lower overall hash speed.
more is not better always.. and WU (Work Utility) is a tricky thing a bit it's largely based on luck of the pool (or your wallet/daemon or what ever)
what that means is if your using some reasonable settings then WU should be random luck from the pool..
BUT if your settings are really shitty that will affect it ALSO + luck so take WU with a bit of a grain salt kind of..
sorry about the last long winded reply about miner tweaking people i noticed a lot of spelling errors and i can't see too good pretty much (mainly my PC setup to blame)
