Are there any disadvantages to using Cool'n'Quiet?

[Xpred]

I was wondering if there are any cons to having C'n'Q on.. What I meant was like I do a lot of playing games, minimizing, etc etc... This seems to undervolt and put back the voltage again where it's at, so going from cool to hot, slow to fast...

Would this damage the CPU in any way? Because it's not like at a regular constant rate? Or anything like that? Thanks.

One of the first things you should do when overclocking is to disable CnQ. Once you have everything stable, then you can try turning it on. It's just another factor in the 'overclocker worry' pool.

If you're running everything at stock, give it a shot and see how it performs. I haven't bothered myself; I don't have much faith in some of the hardware solutions on AMD/NF4 boards (such as the terrible Firewall).

Oh.. I don't plan to o/c... just staying at stock, really. :-D

I like cool and quiet. the cpu drops a few degrees when it's on. go to the amd web site and download a few of the display utilities, it's amazing how quickly the processor speed adjusts up and down.. I can't see how it's going to impair performance when your doing a cpu intensive task, because at that point the cpu is shifted up to it's highest frequency/ voltage settings

if you OC and leave your CPU at the default multiplier and voltage, then you can use Cool and Quiet generally without issue. On the Neo 2 Platinum, I managed this by leaving voltage at default and using the CPU Overvolt setting to increase voltage. Now my 3000+ runs at 2.5Ghz at full load and drops to around 1.34Ghz on C&Q. Temps go from 30C idle to around 25C idle with the feature working.

Seems like it works best when you leave everything at stock...I've disabled it since I really don't have any temperature concerns with my system.

There are instances where C&Q doesn't accurately determine that you're really using your pc, and leave it underclocked---at least that is what I've read a couple times.
