Yes exactly what I was thinking. It seems like it's trying to save power or it doesn't get enough of it.
What's your power supply unit? Do you have TWO 6-pin connectors plugged in the card directly from the power supply unit?
I changed that a while ago and still no change. Sometimes it goes back to adaptive without me touching it too. http://www.newegg.com/Product/Product.aspx?Item=N82E16817822015
That's my Psu.
Yes, I have 2 6 pin connectors plugged in. The power % moves around in the 25-35 and maxed out at 50%. I used to use OC Guru and it says the power target is 50%. MSI Afterburner Power Limit is at 100, but it still has room to go up. When I try to change the power target on OC Guru it eventually goes back down to 50% without me touching it.
