Why disable Cool n Quiet?

Will it make the system more stable? Will I be able to get higher clocks?

Hope this helps.
| Cool'n'Quiet is a CPU speed throttling and power saving technology introduced by AMD with their 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. |
When I last used an AMD CPU I understood it's a thingy that tries to make your cooler run quieter, means with slower RPM. And I have understood it's a very bad thing with OC'ing cause it makes the cooling lack a lot of power. My opinion.
Edit: yes, like reb. posted, it only makes OC'ing harder and fruitless.

no
It changes the core clock and voltage, but when you overclock, you change either the FSB or the multi, and in doing so, you proportionally change the target speed of the chip, it will try and run at 800mhz lets say, and drop the volts to 1.1, but you have your FSB up, so it really downclocks to 1.1GHz, and it gives mad instability when jumping from 800MHz to 3.8GHz (as an example)

Oh, I've always had it enabled, didn't know it caused instability. I'll disable it now, +rep

Custom cool and quiet via K10STat or PhenomsTweaker can save the day =)

Hmm, it may have changed a little since I last time checked info about it or then I just have wrong info. Well, whatever, I don't use SpeedStep or other stuff either.

Just depends!
Agree'd with using phenomMSRtweaker though, and leaving it disabled while checking stablity.
I leave it enabled and have phenomMSRtweaker set to use as little voltage as possible for each of the power states, and I don't use the "custom" C&Q.
But for initial OC'ing and stablity testing C&Q is not a good thing to leave enabled IMO.
Reb's reply is spot on!

Hmm. Well I was stable before, and now my idle temps are way higher. I'm gonna re-enable it, since I'm not clocking my CPU any higher
It would probably have a bigger effect on cpu's that unlock. I have to have my 720be set at 1.4 to get the 4th core stable. so with cnq enabled and it dropping my voltage would make my system unstable. for a normal cpu like my athlon 630 i just leave it enabled and while on idle it drops the clocks conserving energy and lowering temps.
just my 2cents

Mine jumps from 2ghz to 3ghz every 5s, no instability here, and I really don't think its going to affect the lifetime noticeably. Idle temps are 10C lower though

i have the same cpu and it's running at 3.36 at 1.4v unlocked, and no issues at all. it runs at 840mhz at 1.08 volts on idle. The thing i did notice is that things do take a second or 2 longer to load though as it has to ramp up the clock speed first.
Also, it's at 840 almost all the time. Even when i load divx files, it stays at 840mhz. Unless i open a tonne of programs at the same time, it will go up to the 2nd setting (i don't even remember what it is as i rarely see it). It only ever goes at max clock when i'm playing SC2 or running prime/occt.
