I've got a message such as: Invalid reference clock from BIOS: 0.0 MHz – litvin05 Nov 5 '10 at 18:55
Don't care about it. You can set the frequencies ignoring this message. This seems to be a common problem, and most people affected by it (including me) claim that it can be safely ignored and it works anyway. – Rafał Cieślak Nov 7 '10 at 14:29

You can also try AMDOverdriveCtrl:

lsadl is only application i found that can overclock Radeon Mobility(require Catalyst driver), also it can change voltage:

Steps to install:

  1. Download lsadl-0.1.2.tar.bz2 from
  2. Download ADL_SDK6 from

  3. Extract lsadl-0.1.2.tar.bz2 to any folder (lsadl-0.1.2 in my case)

  4. Create ADL_SDK folder in created folder and extract files from to it (lsadl-0.1.2/ADL_SDK in my case)

  5. install sudo apt-get install GTK+2, sudo apt-get install build-essential, sudo apt-get install autoconf, sudo apt-get install automake

  6. in terminal go to lsadl folder ( cd '/home/gap/downloads/lsadl-0.1.2' in my case)

  7. ./

  8. ./configure && make

  9. run program ./lsadl

Succesed with i3 2330m + radeon 6650m graph card on Ubuntu 15.04.

@MadMike: I believe, this is an attempt to answer the question. I don't see any new question in it. – David Foerster Sep 14 '15 at 14:08
Welcome to Ask Ubuntu! I recommend editing this answer to expand it with specific details about how to do this. (See also How do I write a good answer? for general advice about what sorts of answers are considered most valuable on Ask Ubuntu.) – David Foerster Sep 14 '15 at 14:08
I use google and can't found info that i needed for 3 days. This q&a is the first link that i opened, . I can create mine question and answer it myself if it really needed, just want to help people with same problem as i had. Edited post for more detailed info. – Gapster Sep 28 '15 at 22:44
