Overclocking Problems E8400

I've had problems getting this chip to 3.6. I got it to 3.3 in bios easily with a 1.275vcore. But whenever i push it up to 1600FSB it freezes in windows. Currently it's at 1467FSB to get 3.3 GHz. Now i know others have gotten this chip up to 4.0 no problem now why can't I?

Give us more info on your setup by filling out your system specs. But I am going to take a guess.

You are not lowering your memory divider, so your ram is running too high and is causing you to become unstable. If you run CPU-Z, and under the memory tab it shows the ram running faster then 400MHz (DDR2 800 speed), your ram is running out of spec. Depending on what board you have will help determine what bios adjustments to make. You are giving your FSB speed in QDR, does that mean you have an NVIDIA chipset? If so, set it to unlinked and manually to 800.

Overclocked my ram to 1066 5-5-5-15 timings so i guess that would be the problem what would you recommend I do?

Set the ram to the lowest speed and only worry about the CPU OC for now. As you increase the FSB, you also increase the ram speed (at least the base speed).

Also take into account that as you increase the FSB, the NB chipset needs more voltage. Again if you listed your specs, I might be able to give you a voltage recommendation.

other than upping vcore you will always have to adjust your northbridge volts probably to be able to obtain the 4ghz you want on your cpu.

How would I do that and what should I up it too?

it varies from cpu to cpu on how much you need to push your hardware to obtain the 4ghz goal. here is a guide to overclocking using the 750i ftw mobo thati found with 2second worth of searching on ocn.

and also the 750i ftw overclock thread. some people have posted their bios settings in there to obtain the overclocks they have. Maybe you can use that as a reference.
