Rovclock
Contents
Generel
Rovclock is a utility to control frequency rates of your Radeon card.
It is very helpfull 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.
It 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 frequency (-c) to 100 Mhz and the memory frequency (-m) to 120 Mhz.
$ sudo rovclock -c 100 -m 120
- Get current frequencies among other information (-i).
$ sudo rovclock -i
Stable clockrates
- T42, Radeon 7500
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:
100MHz core, 120MHz memory
This reduces power consumption by approx. 300mW compared to the default (300MHz core, 230MHz memory).
