GPU underclocks itself at boot.

[Agent2701]

My Sapphire R7 250X underclocks itself to about half the value of the memory and core clocks. My temps are fine, standing at around 30-35C on idle considering I am living in a hot place and my room isn't that ventilated but my PC has good cooling,it runs at around 67C max when running Heaven benchmark at ultra 1080p. I have a Gigabyte H55M USB3 Motherboard with an i5 750 CPU, I have no overclocks on the system.. a friend suggested that it might be undervoltage in the PCI Express 6 pin connector but I tested it with a multimeter and all the connections are giving out 12.01 Volts. I already reinstalled the drivers and reset driver software factory settings. The card does return to normal clocks though after I open the driver software and reset the clocks for some reason.. Does anyone know the solution to this problem ? Thanks in advance

The clocks lower themselves, when the card is not being taxed, similar to speed step from Intel, and AMD's cool n Quiet, on the CPU side of things. Use GPU-Z to monitor the clocks at idle, vs load. https://www.techpowerup.com/gpuz/
