View Full Version : Athlon64 3400+ only reads 1.8 Ghz

Something is wrong. The Bios says it's 1.8. Windows says it's 1.8. CPUID says it's 1.8.

Isn't it supposed to be : (3400+/2.4GHz/512KB L2/Newcastle(HT4x/130nm/1.5V) ?

I think the voltage is wrong too.

CPUID-


EDIT: Ok new info...

Bios now says 2.4GHz. Also, Windows and CPUID reads 2.4Ghz for a few moments when Widows is starting. Some sort of "speed stepping" going on here?

The Athlon64 3400+ runs at 2.2 GHz (11 x 200 MHz CPU clock). you should set your multiplier to 11.

If your Bios is reporting the speed of 2.4 GHZ that means that your multiplier is set to 12, you should lower it to 11!

I got these readings as startup (I have to be fast with the screen capture).

The funny thing is that I seem to get these readings only immediately after a restart out of the bios.

And 2.4GHz is right with the Newcastle core.

New update:

Keeping the CPUID on top, I noticed when I'm "tasking", the clock speed and multiplier jumps up to correct readings briefly then idles back down. Sounds like some sort of steppig technology to me.

do you mean that your Bios is trying to overclock your CPU by using its Frequency Stepping option? http://forums.3drealms.com/ubbthreads/images/graemlins/grin.gif

why you don't manually adjust your CPU multiplier to 11 !? http://forums.3drealms.com/ubbthreads/images/graemlins/wink.gif

The cpu idles at a lower than optimum speed and when needed cranks up to optimum until no longer needed, then it idles back down.

At least that's how I see it.

LOL! All that is is AMD's Cool N'Quiet power saving/noise reduction techology thing. Start running something CPU intensive, and you'll see your clock speed go back to normal. No point in running it at 2.4Ghz when you're going nothing you know.

Dude's right, it's just the C'n'Q Tech.

We just went through this same thing a few weeks ago....

It sounds like some kind of power-saving thingy is going on to me, too.
Is this computer a laptop?

Desktops can use it too, if you turn it on, so the fans aren't as loud most of the time. Hence Cool N'Quiet

It is a desktop. Question is, how do I turn it off if I want to?

There should be an option in your BIOS if you bought a decent motherboard.

Came with the system. I don't remember seeing the option,though. It's okay though. As long as I know whats going on.

Aren't you supposed to write something when you quote? :P
