i5 750 overclocking
i currently run an i5 quad core desktop with windows 7 home premium. how do i go about overclocking it so that it'll run at 4.16ghz rather than 2.66ghz?

Without knowing the rest rest of your specs (ie RAM, motherboard, cooling) - it's hard to give accurate detail.
However, as a very broad rule - you need to raise your BCLK (baseclock) and increase your CPU voltage (vcore).
How much vcore required depends on your particular chip and the BCLK required is dependent on your multiplier setting.
ie - a multiplier of 20 and BCLK of 200 will give you 4ghz.
There are quite a few other settings to take into consideration as well when going past a certain point. Such as:
► Your RAM speed
► QPI/vtt voltage settings
► enabling/disabling Turbo boost, Speedstep, C1E
► + other fine tuning settings
If you are using the stock intel cooler, then I wouldn't even consider going anywhere near 4ghz.
4.16ghz is a very specific target request - any reason for that clock in particular?

might help you.
well i've heard that it could be done up to 4.16 with the stock cooler apparently. so thought i'd try it out. how do you enable or disable the turboboost? mine is the stock hp p6390d set with 4gb ram?
It can be done, but is definitely not recommended.
Unfortunately, that right there will be your biggest hurdle.so thought i'd try it out. how do you enable or disable the turboboost? mine is the stock hp p6390d set with 4gb ram?
The majority of pre-built machines have 'locked/limited' BIOS options where most of the necessary adjustable settings required for overclocking are just not available.
If your BIOS falls into that category(which I believe it does), then software based overclocking may be your only option.
However this method is less than preferable and I don't know of any software that is suitable for your board.
To be honest, that motherboard is just not suitable for overclocking at all - certainly not for anywhere near 4ghz

First question is what are you doing that needs the overclocking? Or do you really even need it?
