Phenom II and C'n'Q 3.0 - Reviewers were wrong :p:

Hey just wanted to post my results on C N Q and ask a question.

first off this thing really works good Im doing 254 bus speed idle is 1016mhz with the 4x multi at 0.992v (nice for surfing the net) then jumps up to 3.8ghz with the 15x multi at 1.55v when I start a program or game.

The only thing is the HT link is set at 1016mhz and the nb is at 2286mhz I tried setting the ht and nb multi but CNQ disabled when I did that.

My past experience show that for Cool'n'quiet to work, I can not change voltages or multipliers... only HTT speed can be changed. (Since C'n'Q does not adjust the HTT.) If I manually set either voltage or multipliers, C'n'Q doesn't work anymore. (That's on Gigabyte board in my sig.)

I did compare the power consumption from the wall on my PC by having my 940 at 3.5GHz (stock Vcore), and manually downclocking it to 800MHz (0.8V Vcore). The difference in Watts was only ~20W, thus I found it not much benefit to bother with.

I see, in my case though Im running 1.55v for 3.8ghz 24/7 so dropping from 1.55v 24/7 to 0.992v is a bigger difference.

lets say a computer is on for 8 hours

5 hours on idle for websurfing at 1.55v and at load for 3 at 1.55v gaming

now with CNQ 5 of those hours are at 0.992v and the other 3 are at 1.55v

it has to add up over a month

I agree 100% that if you can get C'n'Q working while you have increased the Vcore that high at max performance setting, it makes big difference at idle.
