Intel Sandy Bridge power saving features

post #1 of 16
Thread Starter 
So here's the dealeo, I should be getting my SB CPU + motherboard combo in a couple of days (2500k + ASUS P8P67 Vanilla).

And I was wondering, what are the names of the power saving features I should be disabling once I receive my SB setup? (haven't been an Intel owner since the early 2000s lol).

For AMD, it's called Cool'n'Quiet.

Thanks in advanced guys.

Nice, thanks for the reply mate.

So if I disable that, my CPU won't downclock when @ idle?

you will have to disable speedstep and C1E (I forgot about C1E) and it wont downclock the cpu.

What's the advantage of not downclocking at idle?

Erm, To my experience on P67, once you disable Speedstep - you also disable any OC to get that 5.0Ghz.

Edit: Sin0822, on the ASUS Bios, disabling EIST will turn Turbo option off and leave your SB at Stock speed.

Yes, on Asus P67 boards. On older platforms like 775 I always have C1E and EIST off. Maybe Asus needs EIST and C1E on because of bios problems? AFAIK, their latest bios is still beta. I don't have my CPU yet so I haven't even gotten a chance to play with Sandy Bridge yet.
