Trying to lower idle temps...

post #1 of 9
Thread Starter 
Currently I have my CPU set at 4.6ghz and it will constantly stay at this frequency, what I would like to do is have it so that it downclocks when I'm not doing tasks requiring power ie. gaming and so that my temps go down whilst I'm internet browsing etc.

Could somebody help me out and tell me which of the following I should have enabled to let the CPU dynamically increase and decrease speed?
Perhaps more importantly as well, is it even worth doing?, will my temps go down by much and is it true that it can take a noticeable amount of time for it to increase the clock speed when a load requires it?

Enable Intel speedstep, it should downclock your CPU to 1.6GHz at idle.

That's really the only option I need?
wow, I'm so dumb.
Thank you

I would enable both Enhanced Intel SpeedStep and C1E (and really, C3 and C6 also, unless you have problems with crashes at idle). No reason to have all those off.

Ok I just did a google search on speedstep and I would also need to enable a vcore offset?, what should that be set to

And forceman, what will C1E, C3 and C6 do?

Sppedstep controls the frequency and C1E is a kind of sleep state for the processor (actually an enhanced HALT). C3 and C6 are low-power (actually basically no power) deeper sleep states. If you want the voltage to downvolt when idle along with the clockspeed you would have to use an offset, yes.

Your best bet for the offset is to put in a small positive offset, load a stress test and see what the voltage that gives you is compared to what you needed from the fixed voltage, and then adjust the offset to make the load voltages match. So if +0.005 offset gave you 1.325V and you need 1.34V, then you'd just change the offset to +0.02 instead. It'll take some trial and error to get it dialed in.

I have enabled both C1E and speedstep but CPU-Z does not show the CPU speed going any lower than 4.6ghz still when idle
Is this because there is still some load on the cpu or is it just that it is not working?

CPU-Z will not show the lower frequencies if the Windows Power Plan is set to High Performance. Change it to Balanced and see if that fixes it. You can also check with Realtemp.

Absolutely fantastic, thank you!
Idle temps are down 5c!
