Hi guys,

as some know I have just built my computer and it has been awhile. Now just a quick question, how different is the overclocking on these mobo's and core i7's compared to socket 775 chipsets? Does the rule stay the same when overclocking. I know that the BCLK should stay on 100 and the multiplier would be 50 if i wanted 5Ghz.

What about the FSB, CPU Volt, DRAM and NB voltages? Do i still need to make changes to those as I did with my Socket 775? I have been outdated with the overclocking on the new chipsets, so if i could get some assistance in getting this baby to 5GHz stable, i would very much appreciate it. Currently running 8GB 1866Mhz memory with the 2600k. From what i have heard, it's pretty easy to overclock these, so what am i missing? =)

SandyBridge overclocking has become to easy. You do nothing really. The only thing you have to do is active XMP (Extreme Memory Profile) if your memory support that and adjust the Turbo multiplier as high as it will go. Every time it's necessary you raise the VCore and once the CPU hits 72°C under full load, I'd stop raising the multiplier or the voltage...

I think if you've ever overclocked before, you'll find this to be a snap!

woah, great to hear. Good to be back to computer builds and overclocking! been while. but yeah thanks great help bud! in regards to the VCore, what's safest or does it depend on motherboard?

It depends on the cooling really. Stock cooler, I'd leave stock voltage.
For a Noctua D14 (one of the best air coolers) I'd say 1.35 - 1.38V.
With water cooling I'd say around 1.5V...
But I'd not push beyond 1.6V for 24/7

Okay, i tried it all last night. What am i missing because when i tried overclocking to 5Ghz it won't boot when using 1.35-1.38 Noctua D14? I wanna go straight to 5Ghz as i hear it's easy to get it stable on that with the 2600k. Now maybe i am starting to sound like a newb

Not really. You have to have a good chip to get to 5 GHz. Your's is obviously not as good. Try 4.5 GHz and leave the voltage at 1.35V.
Then stress-test with Prime95 or a similar program, and check the temperatures with CoreTemp (or something similar).

If the temperatures don't hit 72°C on the cores and prime95 runs for like 20-30 minutes, raise the multiplier by one...

Repeat the entire process until you have a error. I suppose if you're lucky your CPU still may do 4.8 GHz. But test with 4.5 GHz first!

Thanks, but i did finally get it to 5Ghz stable =) thanks for your help man.
