[opensuse] Probably not important but
...I have a range of machines running OpenSuSE10.2; The problem is that I do not understand the output from "cat /proc/cpuinfo" On my office workstation, an AMDx2 3800+ it says I have 2x2GHz processors which is what I expect. On the studio machine, AMDx2 4600+ it says the two processors are 1GHz, while AMD assert they are 2.4GHz, and measurement supports AMD over Linux. On this laptop (Centrino) it is reported as 600MHz, but I think it is 1.4GHz. The AMD Athlon XP 1900+ is correctly described as 1600Hz (actually 1600.704), and the AMD 64 3400+ is given as 2.4GHz The value for the laptop could be the power management, except it is plugged it. The AMDx2 4600+ is just wrong. What have I missed? ==John ffitch -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
You've missed something called Cool'n'Quiet. In other words - everything you read is correct, it's just power saving through frequency throttling. /proc/cpuinfo reports CURRENT frequency, therefore if you load your machine e.g. with creating .tar.bz2 archives of big directories, you should imediately see frequency jumping up to the spec values.

My laptop *can* run at 1.2Ghz but if I can run it at 700Mhz it runs considerably cooler and the battery life is considerably longer. My laptop will throttle back from 700 if everything is idle... but under load it will never run at full speed (or full heat).
