General

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

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.

It can also be used to gain performance by overclocking.

NOTE!
While this utility complements the DynamicClocks option of the X.org radeon 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.

Features

Used to under-/overclock Radeon gfx-cards.

  • Controls GPU core frequency
  • Controls gfx-memory frequency

Project Homepage / Availability

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
