Windows 7: CPU Speed.

you speak of cool n' quiet--that is amd's cpu throttling feature (forgot the name of it). if prior to upgrading the bios, your cpu was always showing the full speed, then cool n' quiet was disabled already. so when you upgrade the bios, it set everything to default or optimal, which enabled that feature.

also, in my experience with an asus amd board no less, i have upgraded the bios and had to go into the bios because upon rebooting, i would get an error message stating that the os could not be found--the boot order got messed up from the upgrade. i'm not saying that will happen to you anytime in the future you may upgrade your bios, but it may.

I've never messed around with Cool'n'Quiet though.

And I'm pretty sure it comes 'enabled' by default on all BIOS revisions (for my board anyway).

Unless they're working under a newer version of Cool'n'Quiet now. Who knows?...

Windows 7 and Windows Vista have the option in Advance Power Options. It is under Processor power management, Minimum * state, Maximum * state. Probably on Vista you had the power plan set to High Performance which sets the Minimum state to 100%.

But my advice, let the CPU throttle down when its full power is not required. This will keep the computer cooler and quieter.

Yup, that's probably it.

Minimum processor state is set to 5%:



Thanks a lot man!.

Fujitsu Siemens Amilo A1630 with AMD 3700 runs at only 800MHz, even under load (as confirmed by AMDpwrmon, CPUz, and RMclock). I tried with Balanced and High Performance power plans, with lapyop plugged in to mains power line.

as per screenshot, i only see System Cooling Policy. how do i enable Processor State Settings?

BIOS is latest available from Fujitsu Siemens (1.04c released 2005). There is a 1.05 BIOS available from Uniwill motherboard manufacturer released 2006. I did not try that since Coolnquiet is enabling ok as confirmed by RMclock. CPU would run at 800/2400 in XP.

Try disabling Cool&Quiet or (Intel version)
in BIOS
see if that helps.

no option in the 1.04c bios. tried the 1.05 and suddenly it is working at 2.4GHz again!

i would rather have it stuck on 2.4GHz than 800 MHz

(my bios, for instance, gives me the option when flashing to erase everything or only update specific items while leaving my changed settings intact).
Hmmm...

The thing is, I'm a big chicken when it comes to BIOS, I only change basic stuff like... Memory timings, Boot order, etc...

I would never mess up with something like 'CPU throttle'.

I'm even scared of disabling AMD's 'Cool n Quiet' feature lolz.

It has to be something new that ASUS wanted to incorporate into their new BIOSes.

EDIT: Thanks BTW.
AMD's Cool and Quiet feature is behind the CPU underclock, Personally I want my CPU running at full 24/7 I guess i just don't like the fact that the multiplier is changed on the fly like that. Disabling that will not do any harm to your system and I disable it on every AMD system I've built or used. I belive power saving in many components today is a joke because you really don't save all that much power if you do the math for DC and AC conversion. I say disable it and let your cpu run at what the manufacturer designed it to run at.

You forgot to calculate heat dissipation into the calculation. Hardware components running at a lower clock produce less heat and require less electrictity to run for itself and supporting cooling systems. The CPU is designed to run at a lower clock just as it is deigned to run at a set clock speed.

Having the processor run at 100% all the time when it is not required is just silly.

I do have to agree with you that heat dissipation is plus with cool and quiet, I just don't think a CPU would have a longer lifespan with the VCORE and the Multiplier constantly changing, and I mean CONSTANTLY. Then keeping a steady multiplier and vcore 24/7 and it only would be stressing underload the same as cool and quiet.
