i5-760 Overclocking

[Haider]

Hi,

CPU: I5 760 2.8ghz @ 4.0ghz @ 1.285v 200 x 20 vtt 1.25v

The above got me interested in OCing a bit further my i5-760. Obviously all chips are unique.

I managed to run at 200 blck x 18 multiplier 3.6 GHZ, Vcore=1.225 and IMC/Vtt=1.20 rock solid stable with good temps on an overnight run of Prime95. I then moved onto try a x19 multiplier I moved the Vcore upto 1.245 and was still not able to get 3.8GHz stable. Should I try bumping up my IMC/Vtt? I thought that was only to stabilise the 200 blck. Once you have a 200 blck overclock and you start moving multiplier up you don't touch the IMC/Vtt only the Vcore? Is my understanding wrong?

This is to create a CPU bound gaming setup that I will use for CPU heavy games. My everday overclock that I have been running since christmas is 177 BLCK x 20 multiplier giving me about 3.5GHz. My Vcore 1.24 and Vtt is 1.15. So in theory my CPU should be able to run a x20 multiplier.


Thanks
Haider

Your vcore is way too low to get those last few hundred MHz. I had to give my i5 750 about 1.375v to get up to 4GHz. Your VTT also seems low--Mine was set at 1.3v. Heat was never much of an issue, even with a modest Hyper 212+.

@birthdaymonkey I like your set-up. Active crossover speakers8) Nice cans and good amp for them too, very nice.

Thanks, I like the setup too. Only problem is that those speakers are too much for my poor desk and generate serious resonance despite the mopads I have underneath them. They should be on stands, but I don't have room for stands with the current position of my desk!

Did you make any progress with your OC?
