Hey everyone!

Recently, I've been thinking of overclocking my CPU which is an i5 750 @ stock speed 2.67GHz. I only want to achieve a small overclock of around 3.2 or 3.4GHz. It's still a powerful chip, however it is 3 years old and I would like to bump up the speed on it.

In terms of cooling, I've got it covered, currently have a hyper 212 with dual fan push/pull set up. Idle temps on stock are 29-31C and never reaches above 51 on load. I am also using an ASUS P7P55D Pro motherboard. I was wondering if anyone could share their stable settings. I have never overclocked before, however I've been reading up on it lately and I have an idea of how it works, however most of the guides are for 4.0GHz+.

Other specs that may be important

My setup is nearly identical to yours I have mine running @ 4Ghz 200Mhz x20Multiplier @ 1.325volts, If I were you and I wasn't looking for a huge overclock why not try the built in presets or run asus's Turbo EVO program it should have no issues bringing the cpu to 3.4Ghz and it will test the stability for you, when it's done run the utility again, check the voltage (sometimes the overclocking utility pumps way to much voltage into the cpu) I believe the safe limit is around 1.4V so start reducing the cpu voltage and running OCCT or some 3dmarks in loops, when the pc freezes notch the voltage back up so its stable at the minimum voltage thats required. BTW, I've had mine running @ 4Ghz for the past 2 years and it is rock solid...


Asus Turbo EVO, select tab CPU level up, drag slider to crazy (3.2GHz) hit apply...

Thanks for the reply Donald! I'd like to stay away from ASUS Turbo evo as I have heard it's better to learn how to manually overclock within the BIOS itself.

I just overclocked my CPU to a small 3.2GHz. My settings are IMC @ 1.15v, vcore @ 1.2V, DRAM at stock voltages which is 1.5v and 9-9-9-24 timings @1600MHz, 160 BCLK and a x20 multiplier. Everything else I left as is.

Could someone let me know how my overclock is so far, and if possible I'd like to push this to 3.4GHz so what should I do to achieve that?

Everything seems to be running fine so far in prime95. However, I have heard people achieve a 3.5GHz at a lower voltage than what I'm currently running at which is 1.2 vcore for 3.2GHz. Should I lower that? My temps on a hyper 212 plus are not reaching above 60 at any time. My ambient temp is 26c.

Thanks!

I have done the exact same to my i5 750. I don't think there is any need to go past 3.2GHZ . It is perfect since she needs that clock to run her 1600 ram anyway. I have had wonderful gaming at this clock speed. And I am just running a cheap GTX650Ti.
