AMD Cool n' Quiet Technology

Is it worth it to enable it?

 

[Varun]

100% worth it

i've found it to kinda lag my mozilla firefox while switching tabs. with it disabled, i can switch flawlessly, with CNQ enabled, it takes about 5 seconds to switch..

Something's wrong with your computer then, not the fault of CnQ.

Seamonkey works OK too, no lag at 1 Ghz.

no lag at all, it's fantastic.

it works 100% better than then one provided in the CoreDuo (it sucks big time, the intel version of the "Cool n' Quiet " it's horrible, it doesn't work full scale, it has a lot of annoying limitations)

So if OCing an AMD CPU and running C&Q, you can have a back door way of dynamic OCing?

that will not work in either way, not for AMD, not for intel

once you OC any CPU, you can't use the Dynamic OC features in the mobo/software

 

[LOUISSSSS]

ok its prob my oc then

I use CnQ in conjunction with RMclock on an AMD CPU, and it's better than any dynamic OC software. It's the best of both worlds IMO, I have mine set to ramp/throttle on CPU usage so 95% of the time I'm running nice and cool at just below stock mhz and the lowest vcore my board will give until I launch something CPU intense then it ramps to max O/C.

I'm not talking about using the MB's dynamic OC app. I'm asking if OCing while using the C&Q is a way to HAVE dynamic OCing WITHOUT using Asus, Gigabyte, MSI, etc OC programs...

well if you are OC-ing, and enable the Dynamic OC option, it can cause frequent crashes, if that is what you want.

i kinda found it the hard way 😛

Imo, Intel's speedstep is barely worth it. It only adjusts the cpu multiplier right, not the fsb? So the lowest it can go if 1.6ghz on current processors, somewhere around that.

BTW, it may be possible to have CnQ enabled while overclocking, however I don't think you can do voltage adjustments and still have CnQ successfully work, meaning your max overclock will be limited to what you can do on stock voltage.

On my previous board, Asrock 939 Dual SATA2, I could use CnQ while overclocked. Both voltage and bus. My Abit KN8-SLI disables CnQ as soon as you leave default anything.

Thats why you need to use a utility like RMclock, it gives you much more control including min and max voltages

yup that's exactly what happend on my ASUS A8V board Deluxe, as soon as you go away from default anything, the CnQ will not work, you can turn it on, but as soon as you go into Windows, it craps out, because it tries to OC or under OC it as it usually does, depending on the CPU usage.

Don't use CnQ while Ocing.

 

[paulsiu]

In my opinion, it is a yes. It keeps your machine running cooler and heat is the enemy of component life.

I usually have it setup to increase clock speed on cpu load. I have never notice any speed difference between it and running at full speed all the time.

this is incorrect.

I'm currently running my Opteron 146 with CnQ and overclocked. I run 270x10 at 1.4vcore

when CnQ kicks in cpu clock speed drops to 1.35 ghz and voltage to about 1.08vcore.

 

[Towermax]

Running my 3800X2 overclocked (10 X 240) at 1.35V with CnQ. No problems at all. Drops to 1.2 MHz and 1.12V when not under load--which is most of the time. Response appears instantaneous--when I need power, it's there.

However, I understand that when using CnQ, you can only overclock HTT--no multiplier changes allowed. So, if I wanted to run 9 X 270 instead, I'd have to turn off CnQ. Never tried it, so I can't confirm from experience . . .
