Specifically, it was designed to do so on cards operating with the newest power-management scheme -- where customization of AMD's CCC profiles no longer works to lock clock speeds at the maximum. What makes the tool unique is that it does this in a very generic way through creating a near zero-load OpenCL compute workload ... this workload tricks the drivers (so to speak) in to believing that high clocks are needed, and thus prevents throttling of the card. Such a method works on many videocards and is not just limited to AMD's R9 Fury series, despite that these cards (and the increased power-management in Crimson) were the sole motivation for the tool's creation.
--It's similar in concept to running a high end game such as Crysis 3 concurrent with playing a low demanding one (such as most JRPG's), only ClockBlocker has a virtually non-existant impact on graphics performance (it doesn't produce heavy workload while achieving the same effect).
Features:
-such as, automatic fullscreen detection as a clocking rule (both for Windowed Fullscreen and true Fullscreen modes)
-Settings are also file-based and not stored in registry for easy copy between OS installs and machines.
