Until the issue is addressed inside AMD Radeon Software Crimson edition installer, MSI Afterburner is providing compatibility switch “LegacyDriverDetection” in the configuration file allowing you to use legacy driver version detection mechanism if you’re rolling back to legacy Catalyst drivers after AMD Radeon Software Crimson edition drivers Please take a note that new AMD Radeon Software versioningscheme is not backward compatible so now Catalyst version can be reported improperly if you reinstall older versions of Catalyst drivers on top of AMD Radeon Software Crimson edition without cleaning the registry up. Added version detection for AMD Radeon Software Crimson edition.Please take a note that unofficial overclocking mode with completely disabled PowerPlay is currently not supported for PowerPlay7 capable hardware. Added unofficial overclocking support for PowerPlay7 capable graphics cards (AMD Tonga and newer graphics processors family).Added core voltage control for reference design AMD RADEON R9 Fury / Nano series cards with on-die SMC voltage controller.Other developers are strongly suggested to use it during accessing AMD GPU SMC in order to provide collision free hardware monitoring. Please take a note that direct access to AMD SMC from multiple simultaneously running hardware monitoring applications can be unsafe and result in collisions, so similar to I2C access synchronization we introduce global namespace synchronization mutex “Access_ATI_SMC” as SMC access synchronization standard.

AMD Fiji SMC) in addition to previously supported external voltage controllers connected to GPU via I2C bus. Hardware abstraction layer architecture has been revamped to allow implementation of voltage control via direct access to GPU ondie voltage controllers (e.g.Added AMD Fiji graphics processors family support.Afterburner 4.2 final is ready for download at Guru3D: Revision history - Version 4.2.0
