Flux Mining - GPUS not Stable?

Ive seen alot of people switching to Flux, and OC settings not being stable…
I have gotten my rig to a point where it is not crashing, but it looks like in the charts that im still looking hashing power at certain parts of the day. Any suggestions? OC settings still not right, or not enough power? Im currently using minerpool.org and miniz miner. Thanks!

Any input is appreciated.
