Been lookingon the net, cant find alot of information.

If anyoen has a step by step guide, or could help in anyway (this is my first overclock btw) id appreciate it alot.

Join the forums (You cant use gmail/hotmail/yahoo) and then post on the Intel forums and or the Motherboard forums.They have a few threads on
that mobo right now.I have played with one at work + a few E6400/E4300's and have had great results.The two E4300's topped out at 3.37Ghz @ 1.42v
and 3.45Ghz @ 1.48v,using some Corsair PC5400,another set of PC2 6400 cas4 from Corsair,and a third 2 gig kit/set of XTC pc6400.This was using
the boxed fan heatsink,on an open test bench.All were Orthos blend stable.

What are your spec's beside the ASUS 650i SLI.

C2D E6300
nVidia MSI 7900GTO
WD 250gb 16mb HDD
Tuniq Tower 120 - AS5

What else you want to know?

So if they are hitting 3.4Ghz with stock cooling just think what other cooling types can do including highend cooling, i may hit 3.6GHz with mine :)

There are still variables. Different revisions of cpus can hit different speeds with different voltages. If you get lucky and hit high speeds with little voltage increase your temps won't go up as much. If you need to pump the voltage to hit the same cpu speed your temps will rise a lot and stock cooling won't suffice.

The southbridge should be ok with passive cooling ,stick a nice fan on the NB Heatsink though. Personally I'm sinking mine up to the neck.
Take note of the part in this guys post about the NB
Ive read this a few times from different places about the thermal compund being delicate.

Ive changed my mind about getting an e6600 after seeing the price of an OEM e6400

IMO the ASUS 650i SLI seems to be better then the 680i SLI in overclocking the E6300 and E6400,I have both boards and with the 680i the highest I can get the FSB stable is 1650 and with my 650i it is stable at 2000.But the 680i is able to do 1200 on the memory and 1000 is as far as the 650i will do stable,but running the memory at 1200 is really no faster then running it at 800,the most important thing is how high you can get the CPU FSB.

How do i change the voltages on the CPU. I only gives me set voltages, and the gaps they give me, are too big.

Youve probably sorted your vcore problem by now but...

How much fine tuning do you need ?
That wasn't a sarcastic comment by the way.http://enthusiast.hardocp.com/images/articles/11670109436Mt48LzqAn_2_20_l.gif

No but theres so many options, i cant find what voltages i would actually need to put it on, on an e6300, been tralling the net cant find anything.

When im OC'ing, it always freeze' at 299mhz, and i cant go any higher, i cant figure out whats wrong, driving me crazy.

I think the 300fsb limit may be a problem with that board. Its very budget.

New bios were released on the 19th jan ,u using them, Still not many changes to them?

Also take a look at

Everyones Overclock, voltages, motherboard, type of cooling, etc...
All listed in a table.

I am about to update my BIOS for the P5N32-E as i can't get any voltage between 1.4 - 1.63 :( I really hope this fixes it. The P5N32-E has voltage all the way upto 1.9 which is kinda overkill but is nice to have the option :)
