View Full Version : [ubuntu] Correct speed of overclocked CPU?

June 29th, 2010, 05:53 PM
I'm running Ubuntu 10.04 on a self-built machine with an Asus 785G board and AMD Phenom II X4 910e. The stock speed of the processor is 2.6 Ghz. I've now used the BIOS pre-set overclocking configurations to bring the CPU to 2.86 Ghz. To achieve this I simply used the +10% setting. I also enabled ACC and the Unleash mode, choosing the +6% setting there (the median setting of something that AMD hasn't publicised in any great detail).

Now on startup, the POST sequence shows the new CPU frequency, but none of the Ubuntu reporting tools do. The CPU Frequency Monitor, CPU-G, lshw, all report 2.6 Ghz. I've done a test Blender render though, which is consistently about 10% faster than before. So the 2.86 Ghz figure is the correct one, but how can I get any of the utilities to report it?
