But WattMan tinkering with the goal of improving power efficiency shouldnвЂ™t be overlooked, especially given the unorthodox power consumption of RX 480 reference cards.

So now you know how to overclock the Radeon RX 480, and what to expect when using the tools. If you want to overclock the RX 480, setting State 7вЂ™s voltage to 1,150 will improve stability while you raise clock speeds. The maximum voltage that WattMan can set for any given state is 1,150.

State 7 is the boost state of the RX 480, where the clock speed in WattMan is set to 1,265 and the voltage is set to 1,131. When it comes to the per-state voltage controls, itвЂ™s best to focus your efforts on the highest three clock states, where the RX 480 spends most of its time during intense gaming sessions. (Adjust the cardвЂ™s power limit using the same technique.) We were able to push our RX 480вЂ™s clock speeds up to 1,330MHz, or about a 5 percent increase, before we ran into stability issues. Then you reduce clocks speed a bit and run it for a few hours to verify stability, continuing to reduce clock speeds if necessary. With that done, overclocking a graphics card involves firing up a looping benchmark like Unigine Heaven and then increasing the core clock speed of your graphic card until the benchmark crashes. Graphically rich benchmarks like Unigine Heaven, which loops GPU intensive workloads and reports clocks and temperatures, can be useful for testing the stability and performance of an overclocked graphics card.

But AMD engineers say that +20 to +25 percent will probably more achievable for most cards. Theoretically the RX 480вЂ™s PowerTune limit can be raised all the way up to +50 percent (or lowered to -50 percent). During our testing, we found that the RX 480 performed slightly better if you set the PowerTune limit to +10 percent. If you increase it, you can reduce power consumption-related throttling-which can lead to higher stable overclocks-and if you decrease it you can reduce overall power consumption. The power limit slider dictates the amount of power that your graphics card will allow itself to draw.

Select the game you want to profile, enable the Histogram option for it, and WattMan will begin recording when you launch the game. AMDвЂ™s per-app Profile settings allow you to use WattMan to profile performance while a specific game is running for up to 20 minutes at a time. If youвЂ™re trying to troubleshoot a cooling or performance problem, WattManвЂ™s graphing feature is a godsend.ДЄ thoughtful twist on this performance-tracking feature is the ability to use it globally or with only specific applications. In other words, every crucial measurement you need to monitor while overclocking your graphics card.Д«est of all, if you see something weird on the graph-like a big clock speed drop-hovering your mouse over the issue will bring up the stats for that specific point in time. WattManвЂ™s most striking feature revolves around its real-time graphing, dubbed вЂњHistogram,вЂќ which maps out your RX 480вЂ™s activity level, current core clock speed, memory frequency, temperature, and fan speed. YouвЂ™ll be greeted by the interface shown below.Д¬lick on any image in this article to enlarge it.
