Cool'n'Quiet Question...

[RealityRush]

I was curious, if you change voltage/speed settings in your BIOS for your HTT, RAM, CPU and all that jazz to OC it, can you still enable AMD Cool'n'Quiet??

And if you can, will it still vary the values with the value you set up as just the full load value, so as to still conserve power and temps?

[jjjc_93]

Yeah it can be enabled and will vary voltages and multi's if not in full load..I strongly recommend you disable it though.

The only way I know of to keep CnQ enabled while overclocking is to increase the HTT bus (or FSB). If you manually set the multiplier (and probably the voltage) to something besides AUTO then CnQ won't kick in.

Why's that? Saves energy bills >.<

[ELItheICEman]

It can cause serious instability at nominal overclocks, which is why people turn it off.

Alright, fair enough.

If CnQ is on auto then it will either not kick in, or the CPU will stay at its default multi as a maximum.

I think on my board it stays at the stock multi, and go lower according to load, but it won't go to the higher number I set to OC.

[ELItheICEman]

From what I've heard, CnQ will work as I've mentioned already, up to about 3.6GHz. Beyond that, no matter how you overclock it won't kick in.

I'm currently running at stock and have CnQ enabled, so I'm usually at 800MHz (multi dropped to 4 from 15.5). Once a load hits the multi jumps back to 15.5. Haven't tried bumping the HTT up at all, but I'm thinking about it.

[Nagoshi]

Since you have a black, try bumpign the multi and see what happens. Id like to know what happens. Im pretty sure the maximum speed, with CnQ on, will still be of 15.5x, but Im curious.

Might try it next week since I still have the AM2 under hand for a last week, I could try it on my 7750BE.

[RealityRush]

Heh, just got my pump o-ring in today from swiftech (after 2 weeks... stupid mail), gotta leak test and then I'll try it tomorrow should there be no leaks :P

It doesn't matter with the Multi.

I am currently running CnQ on my CPU.

As long as you don't bump the FSB and keep your CPU-NB Voltage stock then you will be able to run CnQ as the CPU uses preset voltages and clocks for it and when it needs to go back to 100% it'll just put what you have set in the BIOS.

I recommend it to, when I'm not using my system I see drops in temps from original idle by about 8c at 0.9v I think.

Hmmm well I'm going to bump my CPU-NB likely, else how am I going to get my NB clock up to 2600? :P And I was prob going to bump the FSB soooo, this should be interesting...

That's definitely been my experience on both ASUS and Gigabyte AMD motherboards ... so I run with it off. However, for the sake of the planet I do put my computer to sleep after two hours of inactivity ... for the greater good

Trust me it won't work, the difference between 2.4Ghz and 2.6Ghz isn't soo much, you will still be able to have the good snappier run.

2.4? Mine is 2.0 by default.... and I wont be able to overclock worth a **** if it stays at 2.0.

I'd just make my machine sleep, except that I use it to upload... various things while I'm afk, so i wouldn't be able to do so if it slept, and I can't just leave it on full throttle all the time if I'm afk cause then I'm destroying the environment. I'm already running the old 140W TDP 965 BE, so I gotta save whatever power I can.

I've overclocked mine, it can get to 2.4Ghz on stock volts. Yeah, give it a try and see what you can get.

[RealityRush]

Ohhh, u can OC just not the volts... hmm interesting.. alright.

On a side note... DO NOT PUT A THERMOCOUPLE IN BETWEEN YOU HEAT SINK AND IHS, IT WILL DIE, I JUST TRIED.

That is all.

[Titan7170]

Whomever said you cant move the voltage is wrong.............you have to raise the fsb and also raise the voltage to whatever you need for your overclock to be stable. It will lower the voltage and multi for power saving In windows. You can also use the nb and HTT link multi to set them higher. they wont effect the powersavings either.

Firstly, I believe that C&Q varies from board to board, on what can be overclocked with cool and quiet in effect.

For my board(in sig)...
I currently have an overclock of 250x15=3750MHz @1.47v on my 940..
So, C&Q handles it as stated below:
Pstate 0 = 3750MHz @ 1.47v
Pstate 1 = 2875MHz @ 1.37v
Pstate 2 = 2250MHz @ 1.28v
Pstate 3 = 1000MHz @ 1.12v

CPU NB is running at 2500MHz @1.35v
memory is running at 1000MHz @ 2.1v w/5-5-5-15-24
HT Link is running at 2000MHz

So, to sum it up, I can change any voltage, fsb, CPUNB multiplier, HT multiplier, memory divider and timings, etc....
The only thing that C&Q auto disables for on my board, is if the CPU Multiplier is set to anything other than AUTO.

Now, as I said before, I am under the impression that C&Q's auto function differs from board to board, and this is probably why everybody seems to have different results.
I may be wrong about my assumption, and if so please correct me.

I just realized wwe got the same mobo and we got different results My CNQ works perfect just like you said not to do it

I raise the fsb and the voltage and leave everything else alone and it works look at my screenies above
