Intel i5 760 Review
Test Setup and Overclocking
Published: 19th August 2010 | Source: Intel | Price: |
Test Setup
For testing the i5 760 we used a slightly modified version of our standard LGA1156 test setup. The main upgrade is the switch from the Corsair HX850 to the class-leading Corsair AX1200.
ASUS Maximus III Extreme P55
4GB Corsair Dominator GT
ATI HD5870
Corsair AX1200
Noctua NH-D14 with MX3
Windows 7 Ultimate
Intel i7-870, Intel i5-750, Intel i5-760
Overclocking
As I said on the previous page, all of the Intel Core processors are capable of being handily overclocked. The first task is to detune the multiplier and see how far the BCLK will push. The 760 hit a very respectable 225.1 MHz which gives us plenty of wiggle room to obtain both a good high overclock and a nice stable one too.
Starting off with the stable one which we will use for our overclock benchmarks, the i5-760 managed an easy 4 GHz at a reasonable 1.256v on the VCore. 200x20 is something that nearly all Intel chips can do these days and is a very good clock to set your RAM and such like from. All this with such low volts means that even when stressed with Prime95 and using the old faithful Noctua NH-D14 temperatures never went above 60c!
Having attained stability it's time to see how far we can run the 760.
Increasing the VCore to 1.464 we got to 4414 MHz, a 1.6 GHz overclock. As you can see compared to our 4GHz test setup, the moment you cross the 4GHz threshold the extra voltage needed increases far too much to justify a few extra MHz. The picture below links to the validation page.

I only chucked my new 760 in my also new P55-UD5 last night and redone my loop.
Never ever overclocked on the P55 / X58 platforms before but it took about 3 mins to work out how to up to 4GHz at 1.23v with memory at 2000Mhz.
Tried to quickly chuck it up to 2133MHz with an overclock on the CPU of 4.26 GHz but at that voltage it only just booted into Windows.
When I've rebuilt my OS, I'll get some proper overlocking done on it.
Oh yeah, temps while Prime95'n overnight hit a max of 59 degrees.

not a bad little chip is it! Make sure you start a thread about your journey with it dude.Great vid, just ordered myself a Core i5-760, Asus P7P55D-E Pro and 4GB Corsair Dominator GT (2000MHz) kit that should get delivered this weekend. I'll be replacing my old Athlon 64 5000+ (lol!), already got an Antec 300 full of fans and a Corsair H50-1 Water cooler which should keep it cool and quiet. I'll also be using a Corsair HX550 PSU and BFG 8800 GTS 640MB OC2 to round the system specs off.
I've never tried overclocking before and would love to clock this upto the 4GHz you got but without using much overvolting. Is it really as simple as upping the Base Clock to 200, dropping Multiplier to 20x, voltage to 1.250 (That's the VCORE yeah?) and manually setting the RAM timings to match the modules rating? Is there anything I've missed?
Also, I know to do a clean install of Windows before stress testing but whats the best stuff to do my testing? Am I right in thinking clean Windows 7 Pro x64 install, install required drivers, leave off the net without installing any A/V and then starting my stress testing with sometime like Prime95 for a couple of hours, then move onto something like 3D Mark Vantage, Unigine Heaven for another couple of hours.
Is there anything else I've missed of need to know?
Thanks!
