==Generel==
Rovclock is a utility to control frequency rates of your Radeon card.

For laptop use, this is very helpfull to underclock the Radeon card for powersaving when running on batteries.
By underclocking it is possible to prevent the fan from running.

This can also be used to gain performance by overclocking.

==Features==
Used to under-/overclock Radeon gfx-cards.
* Controls GPU core frequency
* Controls gfx-memory frequency

==Usage==

Set the core(-c) freq. to 100Mhz and the memory(-m) freq. to 120Mhz.
 {{cmduser|sudo rovclock -c 100 -m 120}}

Get current frequencies among others info(-i).
 {{cmduser|sudo rovclock -i}}

==Stable clockrates==
* {{T42}}, Radeon 7500<br>NOTE: Setting the memory under 100Mhz may hang your card.
** LCD: 100MHz core, 120MHz memory
** Using DVI output on Port replicator: 100Mhz core, 180MHz memory.
* {{T43}}, Radeon Mobility X300:<br> 100MHz core, 120MHz memory<br> This reduces power consumption by approx. 300mW compared to the default (300MHz core, 230MHz memory).
