Hi
im currently oc'd @ 3.6GHz on my i5 750 using p55-gd65 mb.
im want to get to 4 GHz and dont really know how .... tried to use a guide and increasing a few voltages but it didnt work.....

I need 1.352 to reach 4GHz on my i7-870.
If the mobo runs stable at 180blck you shouldnt need to anything else than to increase vcore and up the multiplier.

i got the same mobo as yours and atm iam on 1.35v VTT 1.225 and CPU PLL Voltage to 1.90v 191 baseclock with a multiplier of 21 = 4 ghz for me with an i5 760 totally stable wink.gif u could try it with ur 750 dont forget to turn on LLC aswell on the mobo set it to Low Vdroop ;p

Keep the CPU PLL @ 1.8v

He doesn't have access to the x21 multi unless he leaves speed step & turbo on. Disable CE1 & C-state

Download real-temp or Core temp to monitor temperature. Try to stay bellow 80C (being my max safe temperature), 70C 24/7.

1.3-1.35 is the average for 4GHz though it could be more for you.
Don't forget to bump the VTT 1.25-1.5 @ 200MHz base clock is average.

Increase ram timing and/or lower frequency to isolate ram from the equation.

I stress test with linx 2Gb memory use. Prime95 is good too, custom profile to use more memory.

Thanks guys it works +1
If I wish to go higher do I just increase it from 200? To like 210?
And increase the CPU voltage or are there more things I need to increase for me to do that ?
I'm probably not gonna go higher until I get a better cooler... Just wanna know for the future...

Thanks guys

It's not that simple. At a certain point you can hit a "wall".
Higher the base clock you have, harder it is on the IMC and others components. I had to increase the PCI-e frequency from 100 to 118 just to reach 236MHz of base clock. Beware because the PCI-e frequency of 100Mhz is also synchronised with your drives and graphic card. Going too high will stress their controller and if those are weak, you could get crash, corruption and even dead drive/ video card (unlikely).
After 4GHz, the voltages begin to skyrocket, trust me on this I've been to 5GHz on this CPU and this is exponential as soon as you got above 4GHz. 4.2 is easily achievable still depend if you got a good cpu. I would try to see what is the lowest voltage you can use without crashing.

What I actually do, is stress testing the CPU a good 3-5 mins and lowering until I have an error, then I increase the voltage of about two notch.

Once you know what your CPU is cabable of, you can aim for higher frequency. I will tell you, it's not worth much unless you really need higher frequency. I mean, lately I haven't been playing at any game, jsut web browsing. I let my CPU run @ 160 x 21, no need cranking it up for that wink.gif
