my AAO running at 798mhz????

when i go to start-my computer-right click-properties i see that my AAO is running at 798 mhz instead of 1.6ghz and i dont know why this is going on can anyone please help????? thanks

 

Are you on battery? The default power saving settings throttle back the processor etc when on battery. You can change them to suit yourself. There's a similar issue with the wifi - go into the advanced properties for the wifi device and adjust to taste.

 

yes i was on the batteries but being on the ac does not make any difference my system does seem run a little bit faster when i am on the ac so ill check out some of those settings that you mentioned. although i do not think that this is the problem

thanks

 

speedstep will throttle your CPU clock based on the CPU usage.

 

ok thanks alot... yes i did notice that some times it had changed

 

Does anyone have a driver that enables this functionality? I've installed the intel .infs (and I would have expected them to take care of it) but my AA1 doesn't appear to be throttling. Note that I have reformatted it and installed a clean copy of XP, with all other drivers installed.

 

try a1ctl, by noda, u can control the cpu speed and devices also

 

How can I turn OFF the auto CPU throttling-down thing? I only use it for 45 minutes or so a day on battery and don't want to deal with a slower system. My Sony Viao had a power management driver I installed so I could adjust on the fly, but the AAO doesn't...so lame -_-)

 

yeah i have been wondering that aswell

ill have a look at what a1ctl has to offer

 

SpeedStep on the Atom CPU is supposedly quite intelligent - it can be demand driven. If you start loading the CPU with tasks it should switch to full speed (1.6GHz). When tasks complete and idle time is detected it will switch back to 800MHz to conserve power.

IIRC, the SpeedStep profiles can be configured by software such as Notebook Hardware Controller and there is a driver in modern linux kernels to allow the same kind of control via the /proc filesystem.

I suspect that the Power Saving profiles in Windows may also have different SpeedStep profiles, so "Always On" would force the CPU to 1.6GHz, "Max Battery" would force the CPU to 800MHz and "Portable/Laptop" would use the demand-driven profile.
