I have 2 cards, both running at 1050/1500MHz set with Afterburner (power limit +50). I had to take out the engine and memory settings from the config file as the memory frequency was jumping around between 150 and max setting. Very stressful on the system. Now everything is smooth. I kept only the temp control as I like the strategy.
My 290 also is jumping memory down to 150 and back, do you have any explanation what might be the reason for this behavior?!
mine also like that. what does it really mean?
