MSI Afterburner gets Big Navi overclocking support and a new skin

Unwinder, the developer of MSI Afterburner has released a new version of the monitoring and overclocking tool.

The new version 4.6.3 Beta 5 has now overclocking support for Radeon RX 6000 series: RX 6900 XT, RX 6800 XT, and RX 6800. All these SKUs are based on AMD RDNA2 architecture and have been released last year. Unwinder needed more time to work on these cards and only after 2 months there is finally official support for overclocking.

Please note that MSI Afterburner will not work unless Radeon Software is configured to “Manual” mode, as the settings applied by Afterburner will be overwritten by AMD software otherwise.

The software also received a new Big Navi themed skin, which is not even mentioned in the changelog. The skin is inspired by a black and silver design of the reference Radeon RX 6000 series.

  • AMD Navi 21 GPU architecture support
  • New hybrid automatic software fan control mode. This mode allows you to combine default hardware fan curve and user defined software fan curve and dynamically switch between those two modes on temperature threshold. Such implementation can be useful on the cards with limited software fan control range (on both AMD and NVIDIA hardware) if you wish to use deault hardware fan curve (with active native fan stop technology) in lower temperatre range and use customized software fan curve in higher temperature zone. This is acheived by new option called “Override zero fan speed with hardware curve” option. When this option is enabled, you’re telling MSI Afterburner to engage default fan control mode in zero fan speed zone of your custom fan curve.
  • Added “Use firmware control mode” option to software automatic fan control module. This option allows customizing fan curve at GPU firmware level instead of doing it entirely in software, so it doesn’t require keeping MSI Afterburner loaded in memory in order to get custom fan curve working. Also this option can be used to bypass various third party issues related to broken fixed fan speed programming API in some display drivers (e.g. Overdrive8 API related screen flickering on some AMD GPUs). New option is only supported on limited set of modern GPUs (Vega and newer AMD GPU families, Ampere and newer NVIDIA GPU families) and it has multipe GPU firmware based limitations such as limited maximum supported number of nodes for the curve (quad slope curve and up to 5 curve nodes on AMD, dual slope curve and up to 3 curve nodes on NVIDIA), lack of step/linear mode switching support, lack of hysteresis adjustment support etc. Please refer to new option context help to get more details.
  • “Erase autosaved startup settings” option is now disabled by default in AMD compatibility properties
  • Process specific memory and videomemory usage performance counters, introduced in the previos beta, are now disabled by default. The counters rely of RTSS, so enabling them will also cause RTSS to be autoloaded with MSI Afterburner similar to the rest RTSS based functionality (such as framerate or frametime monitoring).
  • Improved backward comaptibility, fixed MSI Afterburner crashing when using it with older versions of RTSS without process specific memory and videomemory performance counters support.
  • Fixed monitoring window display in minimized state on the first detach.
  • Updated bundled MSI OC Scanner application. Fake error 22h, which can be reported by NVAPI on early callback function calls, is now supressed and ignored.
  • RivaTuner Statistics Server has been upgraded to v7.3.0 beta 10
