Currently temps dont excede 56c under load with oc - i just sensed that if OC setting is not same on both, it may cause a prob. neither seems to take priority over the other; whatever the last adjustment was overrides previous settings
But if both are to run at startup, then the card would run at the settings of whichever loads later.
By the way, your GPU temperature is 56C, but under which kind of load? A game? OCCT? Furmark?
Did you check the other temperature, like PCB and VRM temperatures, and make sure they are alright?
Did you try adjusting your voltage and lowering it and testing for stability? It would let you run a few degrees cooler.
