Goal – To overclock to 3.8GHz (1600 FSB) with the best settings.
Note 1 – This is my first overclock, but I have read up on many how to guides and tutorials. I would like if you pros’ could look over each setting and see if all is good to go.
Note 2 – Below are the first changes I have done from default, I ran Prime95 for 6 hours, no errors. So now I will be ‘fine tuning’, but I have a few questions.
Note 3 – CPU idle temps are 26-29ºC --- load temps are 43-46ºC
Questions :
1. I set the Vcore to 1.30000 to start with and the NB voltage to 1.20 – I’m going to assume that my overall goal is to get the Vcore as low as I can stable, then bump it up 2 notches, then proceed to get the NB voltage to as close to 1.12 as possible ? -- I read a guide that said to put the NB voltage on 1.12 and not lowest since P5Q mobo’s have weird bug with being set on lowest setting , so always best to one above. (lowest is 1.10)
2. After I do get the Vcore and the NB voltage to the ‘perfect stable’ settings, do I want to [Enable] any of the features that are currently [Disabled] ?
Below are some screenshots (pictures) of CPUZ/RealTemp/HWMonitor etc for the settings below.
