Solved AMD processor running at incorrect frequencies

Specs: Windows XP Professional 32-bit, AMD Sempron 2600+ 1.8GHz S754 | 1024MB DDR-400
Hello everyone,

Recently, I noticed that Core Temp RC3's frequency report was showing that my processor frequency was varying from 2.0GHz, 1.5GHz, and all the way down to 800MHz.

Should it not remain at the full 2.0GHz at all times? I have no idea why this is happening. Since it was working normally, I have replaced the screen, installed new RAM as well as formatted the internal hard drive.

System Specifications:

Acer Aspire 5050 netbook

AMD Turion 64 Mobile MK-36 (Richmond)
Socket S1G1 (638 pin)
2.00GHz, 1.37GB of RAM

Windows XP Professional
Version 2002
Service Pack 3

Also, I noticed that in Window's System Information, it occasionally would show my processor to be running at 1.6GHz, and sometimes at 2.0GHz.

Thanks in advance,

Comguy

There is nothing wrong, if a laptop ran at full CPU speed all the time the battery life would be abysmal, and you could fry your breakfast on it.

Cool'n'Quiet throttles the CPU so it is only work to the capacity it requires to compute tasks..

ARM Devices are the future, great British Design !

Sounds like it's trying to "throttle-down" to prevent overheating. Is the fan working properly? Anything blocking the cooling vents?

@T-R-A

The vents are unblocked, and the side fan appears to be working properly. I've tried to use SpeedFan in order to find out if the fan is running at full speed or not, but it wouldn't show my fans for some reason. It's idling at about 50-60°C according to Core Temp.

Thanks,

Comguy

It's called Cool'n'Quiet technology. Google it.

I already checked in the BIOS. Cool'n'Quiet is already enabled.

Thanks, now that I look at the info you provided, I think you must be right.

I'm more of a desktop person, so seeing the varying CPU frequency sort of freaked me out a bit. I don't seem to remember the frequency doing this before, though...

Thanks,

"I already checked in the BIOS. Cool'n'Quiet is already enabled"

I didn't tell you to "check the BIOS", I told you to "google it" so you'd understand what it is & what it does. C'n'Q is the reason the CPU speed varies. And it's not strictly for laptops, it can be used on desktops too. Intel's technology is called SpeedStep.

"Cool'n'Quiet is a CPU speed throttling and power saving technology introduced by AMD with its Athlon 64 processor line. It works by reducing the processor's clock rate and voltage when the processor is idle. The aim of this technology is to reduce overall power consumption and lower heat generation, allowing for slower (thus quieter) cooling fan operation. The objectives of cooler and quieter result in the name Cool'n'Quiet. The technology is similar to Intel's SpeedStep and AMD's own PowerNow!, which were developed with the aim of increasing laptop battery life by reducing power consumption."
