<hr />
<div>==General==<br />
Rovclock is a utility to control frequency rates of your Radeon card.<br />
<br />
It is very helpful for underclocking the Radeon chip in order to save power when running on batteries. Also, by underclocking it is possible to prevent the fan from running.<br />
<br />
It can also be used to gain performance by overclocking.<br />
<br />
{{NOTE|While this utility complements the [[How to make use of Graphics Chips Power Management features|DynamicClocks]] option of the X.org <tt>radeon</tt> driver, it is not compatible with the power saving mode of the [[fglrx]] driver. Setting power saving mode using both [[fglrx]] and [[rovclock]] results in an unusably slow desktop.}}<br />
<br />
==Features==<br />
Used to under-/overclock Radeon gfx-cards.<br />
* Controls GPU core frequency<br />
* Controls gfx-memory frequency<br />
<br />
== Project Homepage / Availability ==<br />
* Homepage: http://www.hasw.net/linux/<br />
<br />
==Usage==<br />
*Set the core frequency (-c) to 100 Mhz and the memory frequency (-m) to 120 Mhz.<br />
:{{cmduser|sudo rovclock -c 100 -m 120}}<br />
*Get current frequencies among other information (-i).<br />
:{{cmduser|sudo rovclock -i}}<br />
<br />
==Minimum stable clockrates==<br />
* {{A30p}} with Radeon 7000<br />
** LCD: No lower core limit, 90MHz mem (basic use) / 125MHz mem (no artifacts with glxgears)<br />
* {{T42}} with Radeon 7500<br />NOTE: Setting the memory under 100Mhz may hang your card.<br />
** LCD: 100MHz core, 120MHz memory.<br />
** Using DVI output on Port replicator: 100Mhz core, 180MHz memory.<br />
* {{T42}} with Radeon 9600<br />
** LCD: Core: 54.0 MHz, Mem: 60.75 MHz<br />
* {{T42p}} Firegl T2 (9600), fglrx driver<br />
** 1600x1200 LCD: Core: 81 Mhz, Mem: 67.5 Mhz<br />
* {{T43}} with [[ATI Mobility Radeon X300]]:<br />
** 100MHz core, 120Mz memory (see more [[ATI Mobility Radeon X300|here]])<br />
* {{X31}} with ATI Radeon Mobility M6 LY:<br />
** 90MHz core, 100Mz memory (90/90 is giving distorted picture)<br />
* {{R50p}} with FireGL Mobility T2:<br />
** 1600x1200 LCD: Core: 100 MHz Mem: 120Mz<br />
* {{R51}} with FireGL 9000<br />
** Core: 40 Mhz Mem: 100 Mhz (2d only, reducing memory further causes some artifacts and doesn't visibly reduce temps.)<br />
* {{X24}} with Mobility M6 LY<br />
** Core: 95 Mhz Mem: 90-95 Mhz (mem 90 gave me distorted pictures)<br />
