I just built my self a gaming pc. I have gpu-z and cpu-z installed along with msi afterburner. When I run my render test with gpu-z the mhz of the card goes up to 1440. However when I stop this render test and go open up a game, it goes to 889.9 mhz and doesn't go up, but It goes down from time to time. What can I do to fix this so my gpu goes around 1440 mhz like shown in the render test?
