Aí vc tem duas opções, usar o GPU Tweakit ou fazer isso:
The Afterburner utility will allow you to go up to 1300MHz on the core and 1600MHz on the memory clocks.* It also allows you to adjust the voltage up from the default setting of 1174mV up to 1300mV and to run the fan at 100% if you wish to have it running that fast. If you want to go higher than these limits you can get around them if you are comfortable making some changes in the Afterburner files that will increase overclocking headroom. The steps needed to unlock higher overclocking options are as follows:
To enable the unofficial overclocking in this version it is necessary to edit the MSIAfterburner.cfg file located in the installation directory of AfterBurner (typically Program Files (x86) MSI Afterburner).*
You need to alter the following:*
Seek UnofficialOverclockingEULA field and add following text: I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it.
Set UnofficialOverclockingMode to 1 to keep PowerPlay active (may not work on old ASICs), 2 to traditionally disable PowerPlay or to 0 to temporary disable unofficial overclocking path.
Once this is done you'll be able to further overclock the video card, but let's see if we need to do that on this card.*
. So haja bomba para fazer esse loop circular.
