i5 750 overclocking

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?

V1 in 5 seconds?
OP-Sorry for going off topic

well i've heard that it could be done up to 4.16 with the stock cooler apparently.

It can be done, but is definitely not recommended.

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?

Unfortunately, that right there will be your biggest hurdle.

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
