A 'new' kind of Cool n Quiet while overclocking

Just thought I'd share this, I've had great results with using this program to set custom cool n quiet settings on my Opteron 170.

Basically, you can turn off CnQ in the BIOS, and use this program to set custom multiplier and Vcore settings within Windows. I run these speeds for my minimum, medium, and max settings -

-290x4 for 1160MHz, 0.95v - 28C load
-290x8 for 2320MHz, 1.15v - 36C load
-290x10 for 2900MHz, 1.30v - 43C load

I have it configured to raise from minimum to medium at a 65% load, and again from medium to maximum at a 75% load. It then falls back down to lower settings when CPU load goes below a certain threshold.

I had the hardest time getting the vcore to actually change - CPU-Z would reflect the change but my DMM would always read ~1.31v (I had 1.300v set in the BIOS). I fixed this by switching the vcore setting in the DFI BIOS to Auto, and setting my 1.3v by using the "VID Startup" control in the BIOS on my Ultra-D. Now CrystalCPUID can change the voltages from within Windows, and the DMM reads the change, it's also easy to tell by the temps that result

I highly recommend you give this a try, lower speeds are fine for browsing the internet and messing around in Windows. 1160MHz on a dual core A64 is plenty fast
And it raises nicely when you need more power.

wow that's interesting, I have to give that a try
Let me know how it works out for you. I was having some trouble yesterday with games, for example it would start out at 2.9GHz then go down to 1.16 for some reason, and everything would run at 2/5 speed (4x multiplier vs 10x). I think I've found some better settings now, I posted a screenshot to give a starting point

You might want to put interval time for maximum closer to 8-10s though. This means that when you're at your maximum clocks, for example playing a game or encoding something, it will only check to see if they need to be dropped down every 8-10 seconds.

Notebook Hardware controlls is pretty awsome in the said regard...

Perhaps you could try that MY C&Q ^_^ - tell us how that works out.

I tried that before on my setup and everytime the program tried to change the settings, my machine froze... It's also possible that it's just my ghetto rig....
