Cool and quiet question

[oldman420]

As Cool and Quiet on AMD processors seems to effect the multiplier of the cpu in question ie my x2 5000 ranges from 5 to 14 which is the locked range of my cpu. This is indeed cool and quiet and I get horsepower on demand.
What would be the effect of an unlocked multiplier be with cool and quiet, I assume the system will go as far as it can. Would it peg to a 25x multiplier at 100% cpu load or would it be smarter only allowing a safe range to be employed?
And if it does peg out could you use a low fsb to compensate and make the system usable?
Also is cool and quiet configurable ?

I'm not an engineer but here goes . ..

I don't know . . . No . . . Maybe . . . No

But if you are feeling frisky you could try this with CrystalCPUID

I think you can do it with a little hard work. Let us know how it goes.

Good luck!

Cool n Quiet resets the processor's mulitiplier when needed for performance, back from the 5x multiplier to the cpu's stock multiplier, which even unlocked cpu's have. It doesn't change the HTT speed at all, though, which is why you can't overclock any higher than you can go on stock vcore (not to mention, CnQ is automatically disabled, if you change the vcore). With a locked multi, the cpu has to run @, let's say 280 Mhz HTT x 5x multi, which most won't do on only 1.1v (and that isn't adjustable in the BIOS).

And like heybooboo said, using CrystalCPUID, you can raise the vcore when CnQ kicks in, along with changing the CnQ multiplier from 5x to whatever you want it to be.

Some motherboards disable C&Q whenever any CPU parameter is changed from default. My old Abit KN8-SLI did that. My current Foxconn doesn't and I've got a X2-3800 running at 2.6GHz with a slight jump in Vcore. C&Q sets the voltage at 1.1 V and the speed at 1.3GHz when it's activated so it will work with adjusted Vcore.

I never said that at all, I said if you change the vcore setting.

Yeah, if your motherboard supports leaving the vcore unchanged, and using a +X% option, then it's easily done. Most motherboards don't have that option, though.
