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

[Titan7171]

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
