what are your settings for those on stock cooler?

have you had a chance to look at any overclocking forums? i'd really love to help you out more, but we have totally different motherboards, so all of the settings are different.

I have never used the stock cooler my chip is the OEM variety Q6600 G0. Try upping the ram voltage to the same as mine and before you go into the overclocking settings use the CTRL + F1 keys at the same time to get the advanced settings to show for the ram timings to see if they are set properly for yours if not then you can change from the auto to set them manually. Another thing to try is to download then burn/boot from a Memtest86 boot CD to ensure that the ram is functioning properly you should let it go through all the tests at least once others say for few hours like you would do with Prime95.

Edit: Put my settings in with yours quoted.

Underclock the memory, cheap memory is usually the reason why overclocks dont work if its not an extreme overclock. It gives almost no performance impact. Try clocking it at 667mhz instead of 800. If that doesnt work either then you probably need to up the FSB more since some processors have "holes" where they cant boot at a certain FSB range, just go straight to 3ghz, you cant hurt anything since the computer will either boot or it wont.

Also you can lower the CPU voltage to lower temps. The stock voltage is incredibly high compared to what the CPU actually needs even when overclocked (a really high overclock might need higher voltage than stock, but that would be so loud with the stock fan that I dont think anyone could stand it). After you achieve the overclock you want, just keep lowering the volts until you get a bluescreen when booting windows, then raise them to where you can boot and run prime95, keep raising the voltage by one step each time until it doesnt bluescreen when under load. I have a core2duo overclocked by 1ghz and the temp is 2 degrees lower than it is stock since I was able to lower the voltage by so much.

Dont be scared of temps or clocks, this isnt the 90's, processors and motherboards have built in protection systems so you dont damage anything. I would be more concerned with overvolting, but I accidentally volted my CPU at 1.5v thinking it was 1.15v and it didnt hurt anything (1.5 is way passed the max voltage intel says to use), so Im guessing they are protected from that too.

Yes I would try something like the 9x334mhz for just over 3ghz with 2x memory multiplier making sure that the memory voltage is increased a +.2 then in the power management make sure the smart fan control is disabled along with the speedstep then the C1E enabled as well as the TM2.

Also you can lower the CPU voltage to lower temps. The stock voltage is incredibly high compared to what the CPU actually needs even when overclocked (a really high overclock might need higher voltage than stock, but that would be so loud with the stock fan that I dont think anyone could stand it).

His stock voltage is extremely low as it is already at 1.21250v by the default VID of the chip. Which is the same as the chip I have if his board runs anything like mine this means he is running at about 1.17v real after the vdroop when booted, full load about 1.13v or if idle at about 1.04v with C1E enabled at least this is how it works with my same chip/board combo I run.

i dont think i have been disabling the smart fan or speedstep. would this be a reason for not getting 3ghz? i am priming for 2 hrs with no errors at 2.91ghz with temps being about 66-69 for the majority of time

It can be a problem with the speedstep enabled it screws with my overclock. A couple of hours without errors suggests to me that it is working you may want to try for a little higher and you really may want to consider better cooling on the CPU those temps are on the high side of what they should be.

You dont have to overclock in small steps, thats only for really high overclocks where you are approaching the CPU's limits. Just go to 3ghz if thats what you want and are prepared to deal with the noise. After that lower the voltage as much as you can without bluescreens, you can easily lower temps by 8c or more by doing that since voltage is the main source of heat.

And I wouldnt disable speedstep with stock cooling. It lowers your multipier to like 6 when you dont need the power, keeping it much cooler, it will bolt back up to 9 once you start working. Speedstep will make it look like your processor isnt clocked as high as you tell it if you look at something like CPUZ, but it is, you just have to create load so the multiplier adjusts itself back to 9.
