my little chip started life at 2.66 now its at 3.0. the temp heat some times get to 35c..anyway i can reduse the heat? the case is a Tempest Airflow King case...BY NZXT with a zalman fan heat sink onit..anyway to reduce the heat?
intel core 2 quad chip Q9400

Temperatures go down by increasing airflow via various methods, improving cooler, improving contact between cooler and chip, decreasing ambient temperatures. 35 is nothing but I also suspect these to be idle temperatures, better to measure maximum reached while running prime95 or intel burn test.
Heat (flow) is the rate at which thermal energy is being removed from your chip, this is constant for a given load and equilibrium temperature as the processor is giving out a constant amount of heat and not changing temperature.

hehe i did apply new compact paste on the cip and it seems fine..when i removed the cpu fan off the chip it has no paste seems to got rubbed off 
but it seems fine now
temps are 28-36c now and a little more when running a heavy game on it..

Boot windows, load cpu id hardware monitor
write down your vcore reading, this is your 'vid'
Boot bios, set all the chipset voltages to the minimum numeric value available, ram voltage to the specified on the sticks, cpu voltage to your 'vid'
Keep an eye on temperature when testing, stop if it goes above 75 and worry if it goes over 70
Set cpu multiplier to minimum (probably 6)
Increase fsb by 10, boot windows, run 15 loops of Intel burn test, if stable, repeat
Decrease ram speed if it goes above spec during this process to make sure it isn't overclocked ram that's holding you back
Eventually you'll fail ibt. You're no longer stable, put vcore up one notch and repeat until it's stable
Stop when voltage goes higher than you're comfortable with (over 1.3625 is more than intel are happy with), or when temperature goes too high. If voltage has gone up several notches with no improvement, put it back and try one notch of northbridge or fsb term. If it doesn't help, put it back and try again. Some combination of these three will make it stable. Northbridge and fsb term probably shouldn't go over 1.3V
Eventually you get the highest fsb your board can do. It's around 475 on mine without considerable effort stabilising it. This is a useful number to know for the next part
Put multiplier up to maximum, and do exactly the same thing again. Your ram is good up to 533 fsb without overclocking it, you won't hit 533 fsb so good choice of ram. This time when you can't go further, you're probably done. If you cant go further while a long way off your maximum fsb, try putting fsb up by 30 or so and see if you can stabilise it there. There are fsb holes related to the northbridge strap.
Perhaps not best, but as a method its pretty solid. Might draw a flow chart one of these days
p.s. It'll run faster at lower voltages when its cooler. Despite this, keep your current cooler unless you're limited by temperature before you're limited by voltage

You're too kind Greebo. Sensible though my approach seems, it still hasn't achieved results even close to your q9650 yet. I'll have another go once I get my motherboard/cpu working again 
Watching your 5ghz thread with interest, good luck with it

Yeah, I'll start posting some settings and findings soon. The most interesting one was the one very small change which got me past my 515 fsb block and up to 539. Just changing the cpu skew timing to +50ms made that possible.
My problem is that I am still learning as I go on. There are just so many things which you can change in the bios and you just don't know whether that is the key to upping it higher.
I cam across the skew timing by accident after being stuck for about 8 hours and almost deciding that 4.635 Ghz was my limit.
There is still a long, long way to go to acheive full stability above 4.6Ghz but that's another day...............

3.0ghz Should be achievable by oly upping vcore id say, i obviously have a similiar chip (in my sig) which doesnt go above 1.25 till 3.2 or so.
But dam thats a good OC greebo, something to definitely get me trying again, i got up to a 490 FSB block on mine couldnt get it past 30 mins stable ><

I had that problem which I why I changed mobos. I knew my cpu was good for 4.5Ghz (bought 2nd hand) but with my x38 I hit a fsb max of only 444Mhz which was appauling.
tbh 490 is a very, very decent result for an x48 board and I have seen very few which have hit 500fsb.

Yer atm i just staying on 440-450 24/7, its just way too time consuming when you get to this point.
Slowly been building up my other OC with everything set to manual. I'm not massively experienced so it can be quite fustrating.
