Cool n Quiet n Overclocked

[DanceswithUnix]

I've never really played with much overclocking, but surely if you're just raising the fsb (I know it's not fsb, but can't think of another term that's not confusing ) C&Q won't have that much effect on overclocking? Maybe at the extreme levels, but the lower multiplier would surely balance out the effect of increased fsb at lower speeds.

I am certainly hoping that is the case!

As the CPU load ramps up it just increases the multiplier - maybe this occurs to quickly to be stable on a high overclock, but a medium one should be ok I'd have thought. (I'm also someone who wants to run with C&Q all the time).

Well, a medium overclock is all I was really looking for, I don't really have the time to spend eeking every last Hz out of the machine.

I am also fortunate that I was a tad tight when I bought this CPU, as it only has two power states (1.0GHz->1.8GHz) whereas the S754 A3700 I use as work seems to go 1.0->1.8->2.0->2.2->2.4 which might be a bit more of a 'mare to get stable.

Off to try upping to 20% now

My 3000+ runs 2Ghz at 1.1V so I don't bother with CnQ, my stupid Asus A8N-SLIs refuse to give less than 1.1V to my CPUs so CnQ would not help at all to cut power usage.

DanceswithUnix - My motherboard (Gigabyte GA-K8N Ultra 9) allows overclocking with Cool & Quiet, provided only the FSB is adjusted. If I adjust any other settings like multiplier, voltages the C&Q stops working.

Here is a link to an excellent article on how to overclock/underclock while using C&Q.

Well, thanks to everyone for the information! The information in those links boosted my confidence in what the CPU can handle even at low voltage.

I am now up to a 33% overclock, and so far so stable. I wrote a small shell script to display the current CPU frequency, and can watch it flip up and down whilst compiling etc and it all seems OK.

At idle with Q-fan I find the AMD stock cooler is quiet enough (~1200RPM)

Thats your problem there, switch out your stock cooler for something better, I'm running an X2 with a thermalright XP-120 heatsink and a 120mm akasa amber series fan on it. With Q-fan on it's running at ~700RPM and both cores at full load it doesn't get much faster or hotter.

both cores at full load it doesn't get much faster or hotter.

OK, I realise that there are better ways to get the heat away from my CPU, but I really don't want to create that heat in the first place!

The PC is in a small room which, in summer, gets pretty warm even with the window open. Using CnQ cuts down the amount of heat generated, which keeps the room temperature down by a few degrees C.

Still, 700rpm sounds nice, and I would feel safer with that than that big passive Scythe one I was eyeing up the other day. Perhaps I shall put one on my birthday list

The scythe Ninja is a super cooler tbh... If you buy from Scan or Tekheads you will get the plus version which includes a very slow spinning 120mm fan I have one mounted on my Opteron 146 and it is keeping it nice n cool.

Just make sure it'll fit in your case.. it's blinking enourmous!

I'm running my 3000+ at stock passive now. It gets up to 44'C at full load but there isn't a fan on it so I'm happy enough. Now if I could force my Asus board to provide a lower voltage (1.1V is not low enough). I need 0.95V.... I know my CPU can do it since I was running it like that on my old mobo...
