Hi,

As some of you might know i have just built my rig using the following specs:

Fractal Design XL case

MSI Big Bang Xpower II motherboard

Intel i7 3820 core

Corsair Vengence LP 1600mhz 32gb RAM

MSI Twin Frozr II GTX 580 gpu

Corsair Force 3 120gb SSD x 2 (RAID-0)

Hitachi 1tb 7200rpm HDD

LG blu-ray drive

Corsair AX850 psu

Noctua NH-D14 cpu cooler

Noctua fans throughout the case

I have been attempting to overclock it for stable everyday use, and i think i have finally managed it, after a week of attempts and fitting it around work!

I should let you know that all my noctua fans are in U.L.N.A mode, even the cpu cooler.

I first started using the OC genie button on the MSI board, and that gave me an OC of 4.0 ghz, which wasn't bad, but i wanted to see what i could do. Mind you i have never attempted an overclocking in my life, so this was all new to me! I did plenty research as to how to overclock and what kind of ball parks figures people were achieving.

I initially maxed the multiplier to 43 to give me an overclock of 4.3ghz, but this was no way near what others had pushed it to do.

I then reduced the multiplier to 37 but increased the bus speed to 125hz, which gave me 4.6ghz overclock, this was roughly the figure i wanted to achieve. i had to increase the Vcore to 1.28 initially, but after 3 hours of prime 95 it BSOD'ed.

I then raised the Vcore to 1.30, but again after 4 hours of prime 95 it BSOD'ed!

I then thought of raising the multiplier to 38 and increasing the Vcore to 1.34, to give me an OC of 4.75ghz! And it's stable! After about 12 hours of prime 95 it hasn't missed a beat. I have run approx 2 hours of small FFT, and 10 hours of blend.

As you can see the average max temp across all 4 cores was 68.5 degrees. I didn't have a room thermometer to read my room temperature, but it is a fairly hot day. Temp about 20 degrees.

So OC of i7 3820, with 125mhz bus speed, 38 multiplier and 1.34Vcore, gives me a stable 4.75ghz. Pretty happy here

I thought i'd share my first OC attempt ever, and see what others have achieved on their cores.

EDIT:

27/04/2012

I managed to get stable to 4.875ghz at vcore of 1.38

Temps accross all cores at full load on prime 95 after 1 hour of small FFT averaged 74 degrees which still isn't too bad.

Great Clocks man... Good to see that your properly testing for stability and not doing a quick and dirty OC....

Thanks, because on the NH-14 cooler, only ram i could fit was a LP one, and the only one that i knew of was the corsair vengeance LP. It's rated CL8 1600mhz. I've only managed to clock it at 1666mhz with CL9. anything else gives me BSOD or failure in prime 95. I haven't fiddled too much with RAM but i might do that in the near future!

Thanks again, Yeh i have never done this overclocking business before, and i didn't want to harm any of my shinny new equipment I did however try for 5ghz, but i gave up when it wasn't stable at 1.48Vcore! I don't know how far to push this cpu you see. I know from the sandy bridge cpu's people say anything over 1.4 is dangerous in long run. Whether or not that would include the sandy bridge-e cpu's i don't know

Now that is a question! I might have to download it and see. But i'm sure it'll come out on top!

I just can't believe how fast this machine is, i knew it'll be fast but this has exceeded my expectations!

Thanks! Couldn't have done it without the help of everyone here. Now i just need to figure out how to OC the gpu. I done everything else, that's all that's left

Just to update, i had a few issues when booting, i press the on switch and computer will come on for like 1-2 seconds switch off then come back on like normal, this was starting to get annoying so i did research and found that if i disable the EUP2013 function it should be ok. I did this and it worked! easy work around! I even used the multi bios switch to revert to the default bios settings and work upwards (thinking it may have been a bios upgrade issue) but it wasn't. So just giving a heads up to anyone experiencing a similar issue, try this method first, saves a lot of time!

Also when i did some bench marking with cinebench it said my CPU was clocked to only 4.5ghz, but CPU-Z said i was running at 4.75ghz, is this normal? I figured cinebench could recognize my overclock. But i got a score of 9.20, which doesn't mean much to me?
