To overclock the Red Devil, we maximised the frequency/voltage curve in Wattman and set the power limit to its maximum level (+50%). Unfortunately we encountered some hard crashes with the memory slider set to its maximum level of 950MHz, but 925MHz was perfectly stable. All of our overclocking testing was done with the OC BIOS.
Average clock speed under load
This overclock pushed the card's average clock speed up by another 115MHz, beyond 2050MHz.
Games
This overclock bumped up our frame rates by another 4%, so it's certainly nothing stellar but then again you'd still take it over stock performance. Versus the reference 5700 XT, the manually overclocked Red Devil averaged 8% higher frame rates across these three titles.
