E6600 overclocking Help!!

[WingZero30]

Hi guys

I posted before on this issue but would like some more help please. Basically I am overclocking E6600 on Gigabyte ep45 ud3lr. I managed to overclock E6600 to 3.0GHz on stock voltage 1.3250V (VID) and it ran small FFTs in SP2004 Orthos perfectly. However I wanted to overclock more to 3.4GHz so this is currently what I get:

- [email protected] (346MHz X 9) CPU Vcore = 1.33750V (stable value)
- [email protected] (356MHz X 9) CPU Vcore = 1.35625V (stable value)
- [email protected] (367MHz X 9) CPU Vcore = 1.39375V (currently not stable)

It seems I am facing law of diminishing returns where for a constant FSB increase of 10-11 MHz I am inputting more voltage . The CPu Vcore increases in increments of 0.00625V. So my next value is going to 1.39375+0.00625V = 1.40V.
If E6600@ 3.30GHz passes 30mins Orthos test at 1.40V it would seem quite a lot for 3.30GHz. I have a feeling that to reach 3.4GHz I could end up increasing CPU Vcore to 1.48V.
I have checked intel website and VID range seems to be 0.8500-1.5V. This means I could end up getting dangerously close to max value. Also during overclocking I had mobo power saving feature on. Would this have any effect on the CPU voltage consumption or should I disable it? Also do I need to increase any other voltage? How are people able to reach 3.6GHz and beyond on this CPU and my mobo is supposed to be a good overclocker. So I would really appreciate advice please. Thanks.

Thanks guys for your very helpful insight. Rroff How did you manage to get your E6600 to 3.825GHz when taking into account the motherboard. Looking at the manual my P45 which is the later version, it states 1600MHz FSb max (quadpumped). This means my motherboard can only support up to 400MHz FSB max resulting in 3.6Ghz. So how did you get past 3.6Ghz. I thought by doing so you would end up damaging your mobo?

When overclocking the FSB will go beyond the board rated - some P45 board will hit 600MHz (2400MHz Quadpumped) - the board I was running it on was a Gigabyte P35 that was good for upto 515MHz with a 9x multi dual core.

Thanks again for very useful post . Would the board happen to be Gigabyte P35-DS3? Also should I go back to 3.2 GHz and just up the VCore by one notch to be on the safe side in terms of stability. Would I notice much difference in the performance of game such as Crysis between 3.2GHz and 3.4GHz?
