Cool'n'Quiet & C1E with Overclocked AMD CPU?

post #1 of 9
Thread Starter 
I have a AMD 955 BE CPU. I'm overclocking it by upping its multiplier and voltage.

Once I find its stable frequency limits, is it a good idea to enable Cool'n'Quiet and C1E?

I'd like to also keep the system in sleep mode for most the time when its not in use. I ask because I'm reading a lot of conflicting information in this topic.

Thanks! smile.gif

I usually disable, most motherboard offer clock profiles these days. I just pick a clock profile at bootup and roll with it.

I run cool and quiet on my 955 but disabled C1E. No issues here, all the cool and quiet does when the volts are set manually is adjust the multiplier when you are not using the CPU so it lowers the temps at idle.

Edit: Also I forgot after a certain multi I think x19 cool and quiet quits working.

I have it enabled on my AMD rig (link below), but my goal was to have CnQ fully functional on that machine since it sits idle alot.

The downside was that I had to add more voltage to get it stable, and OC the FSB baseclock since CnQ only works up to 17.5X mutliple on my board. The upside is that it idles at 900-something with lower VCore.

If you pretty much use your rig for gaming and turn it off when done, I wouldn't worry about CnQ.

PS: Sleep mode may or may not work properly on any overclocked rig, and I've found that the more you sleep/unsleep, the wonkier a machine can become.

It's a good idea to enable it once you get it stable and as long as it doesn't interfere with your overclock. It does cause instability on my high overclock and my CPU is always under load folding, so I have mine disabled.

I usually recommend keeping both enabled. Lowers idle temps, ups chip longetivity.

This is what I did and it appears to work without issue. I'm running my 955 cpu at 19x multiplier @ 3.8 GHz and no issues yet, and it drops down the 4x multiplier when idle. Though I haven't REALLY stress tested it beyond playing games.
