Yeah all us AMD overclockers need to remember under CPU Configuration to disable "Cool 'n' Quite" in the BIOS.

Off topic:
Is that your current 3Dmark06 score man?
It seems a bit low for your setup...

i get the same, or slightly higher, score as Gen running at the same speed CPU and my 4870x2. CF is CPU dependant, and these things don't clock too high, unfortunately

btw, if anyone is interested, in my BIOS there are two options...

Auto Xpress and CPU Tweak

CPU Tweak disables all power saving on the CPU and has as side effect of bumping up the idle temps by a few degrees.

and both settings, when enabled, will improve system performance and bench scores.

Are there any risks in turning CNQ off?

I assume if you have sufficient cooling there would be no worries?

No, no risks in turning Cool 'n' Quiet off as far as I am aware.

Basically it takes control of your CPU's clock speed (and voltage?), and will turn it down to conserve energy while your processor isn't being utilized. For general desktop computing (word processing, internet browsing etc) it would be wise to have this feature enabled as it can "in theory" cut down on the total heat outputted by your CPU and reduce the total power usage of your PC whilst idle.

The problem with this feature for us overclockers is that we need our CPU clock speed and voltage to be constant at all times to keep our systems stable. Hence why it is recommended turning this feature off when overclocking.

Correct me if I am wrong

mine has been stable up to 2500MHz, some people are stable past it and some aren't stable that high. i would say keep it under 2250... but do some testing and see what your max is.

Heres my numbers guys.. by the way I turn down my Vcore to 1.28. I dont know why Cpu Z didnt validate that but trust me 1.28 Vcore for 3.109 Idle temp is 40 C and 49 to 52 at full load.

Ok I never OCed a phenom before. So what do I need to do?

I was thinking like 200x16=3.2ghz. What voltage do I need to put up? I keep hearing I have to OC the NB and stuff.

Nice! You're using the same board as me. A few questions for you if I may...
What BIOS version are you running? The latest on from Asus or one of the previous ones? and did you play with the North Bridge settings at all to get that overclock?

I have been really confused as of late by all the NorthBridge settings and when I've been overclocking up to this point I generally only up the vCore on my CPU to get stability. I've been searching around for a some detailed descriptions on what all the NorthBrige settings mean but have had no luck.. I am sure those settings are the missing key for getting a nice stable clock over 3.2GHz... Well at least I hope it is

Any thoughts?

On my board I can get 200x16=3.2GHz with my CPU core voltage set to 1.472v keeping both the HTTLink and NB at 200x10=2000MHz

Hope that helps!

Okay, no way you can do 3.1Ghz with only 1.28V.... at least 1.38V is needed for a stable overclock, that is if you only upped the multi to 15.5x!!!
I wasn't even stable at 3.0ghz @ 1.35V with my board, and its the same thing as yours 790FX+SB600!!!


Can you explain your OC more in-depth? Like HT Link, HTT speed....

Optimal for 3.1Ghz would be ~1.4V
