When it comes to overclocking ATI Radeon graphics cards under Linux the only real option has been using rovclock. Rovclock is a Radeon overclocking utility written and developed by Sebastian Witt. This tool has been in development since 2005 but it took quite a while before the Radeon R300/R400 series was even supported. Rovclock still lacks support for the Radeon X1000 (R500) series, however, there is a new contender to the ATI Linux GPU overclocking arena and that is ATIpower. We have covered the ATIpower overclocking utility today at Phoronix.
