XFX Black DD Radeon 7790 1075M Boost reviewed

The AMD OverDrive tool can be found in the Catalyst Control Center, but it did not let us take the GPU clock past 1200MHz. The memory clock was limited to 1600MHz, which is actually the default clock on the XFX card. We faced the same limits when we tried using EVGA PrecisionX and Sapphire TriX tools. In MSI Afterburner there is an option which allows users to override AMD’s overclocking limit, so we gave it a go. After a reboot we saw that we could pull the slider over 1200MHz. At 1200MHz the card was stable, but it was also stable at 1260MHz.
