hi all,
i have just installed suse 11 and when i call up the sys info the mhz it thinks it 1000mhz most of the time then changes to 2800mhz every so offen which it is surposed to be then goes but to 1000mhz when the cpu is the athlon x2 64 5400+ 2.8mhz
any help will be great
thanks

Power mgmt throttling the CPU? That’s fairly typical behavior.
I don’t own this CPU, but what you’re saying is consistent with
other CPUs developed over recent years.
It’s not supposed to affect performance any… just keep things
a little bit more efficient power wise.
oh ok thanks, is it why when i do cat /proc/cpuinfo it recon each core is 1000mhz when it should be 1400 each core making it 2800
Each core 1400 x 2 = 2800 is not how it works.
Each core is 2800
There are two cores, the core speeds are not added together to achieve a a higher clock.
The 1000 that is shown, is the speed the processor is running at. It has been slowed down by your Bios settings.
If you do not like this behavior you can disable it in your Bios so that your processor cores run at full speed all the time.
You can set the power management policy. Install the yast2-power-management package, which is just a frontend to the pm-utils.
ok thanks i will give it a try
