![]() The chipset drivers also automatically install the required AMD-designed power plans. ![]() You'll need to install AMD's chipset drivers to enable the UEFI CPPC2 interface, which allows the operating system to prioritize scheduling threads into the fastest cores of the processor first. It's sold separately, though. We also used a beefy custom watercooling loop with two 360mm radiators for overclocking testing. AMD also collaborated with Cooler Master to develop the Wraith Ripper heat sink/fan combo for its Socket sTR4 interface. We tapped the Enermax Liqtech 360 TR4 II for cooling the processor at stock settings. According to AMD, this partial coverage is fine for stock operation, but we prefer full-coverage coolers. AMD ships all Threadripper CPUs with an Asetek bracket that provides partial coverage of the massive heat spreader using supported closed-loop liquid coolers. With more powerful cooling, higher overclocks will be possible.Generally, stock coolers that worked with the previous-gen Threadripper models should suffice for most users, but beefier coolers can unlock more performance. For cooling, we stuck with the stock cooler – which is not optimal – but we wanted to present a worst-case scenario. To overclock our Ryzen 4 2400G we experimented with Ryzen Master and topped out at an all-core overclock of 3.925GHz, with 1.55 volts supplied to the CPU. This latest version of Ryzen Master, version 1.2, adds support of GPU overclocking and lists current and power draw right along the top in a neat row. Although there are individual sliders per core, they all work in tandem at this time. The software even gives users the ability to disable cores, if they'd like to push a fewer number of cores as high as possible, but that feature requires a system reboot. Ryzen Master lets you alter multipliers and voltages from within Windows, monitor temperatures and clocks, and save settings to different profiles. ![]() Its latest version of the Ryzen Master utility looks very much like the Wattman tool available with Radeon GPUs. AMD is doing some things to make overclocking as easy as possible though. ![]()
