I have no idea what causes it, my speeds just went up to 22ghz while i was multi clienting a game

Cpu-z will say 4,5 and the right voltage
the voltage core temp reads is off too, it maxes out at 1,272 volt, not 1,3

so far I've only changed clock ratio to 44x and vcore auto'd to 1.36. ran IBT at standard (should I do maximum?) to test for initial stability. When I set it at maximum though, cpu-z reads core speed and multiplier at 4.4/44x, but during the test it would drop down to 3.5/33x. Is that normal? I also have it set at 8 threads. At maximum and normal they both complete successfully. I'm on Step #3 now and just set cpu vcore to fixed and at 1.34v, which is two notches down. I'm about to test for stability again. Am I doing this correctly so far? lol
nevermind, my cpu speed keeps throttling during stress tests. lowered my multiplier and samething, think I'm just gonna run stock; I'll give it another try on the pc I'm building.

I just wanted to thank you Sin0822 for this guide. Very helpful!

They say every chip is different... I can do 4.5Ghz with 1.308V but I need 1.356V for 4.6 and1.380V for 4.8Ghz, at least with this board. Not worth it, right?
Power consumption for the rig below (from the wall), with 2 HDDs, 3 200mm fans and a PSU probably below 80% efficient at loads under 20% is:
~92W idle, 190W load (Prime95, 4.5Ghz), 176W (Cinebech).

Hey, I've been reading some guides and I was wondering about at which frequencies do you need to start manually adjusting VCCIO and PLL voltage?

Is the chip or the board that makes it need alot of volts to be stable?
I think i might have got a not so good chip.
even at 4.5 i need 1.416 to be stable
update.... that wasn't stable......
So im lost

Hi guys! I am new here.

I wanted to ask somebody to help me with OC of i5 2500k on Z68X-UD3-B3

It's actually the first time I found tutorial with BIOS as mine.

What I want is settings of BIOS which works for you. I don't think 2600k is much different, so please post 2600k setting as well.

I just can't get, how to set-up all feautures. For example what's better, to OC via offset or LLC? Do i need turbo boost, and so on.

Thanks in advance, Alex

I currently have a P67X-UD3-B3 with a D2 Revision i7-2600K, currently untouched and running fine at stock.

My RAM sticks are currently G.Skill Ripjaws X DDR3-1333MHz PC3-10666, 4 x 4 GB (total 16 GB), 9-9-9-24 @ 1.5V.

I would like to overclock my CPU and my RAM to a reasonable, stable speed. I'm not extremely greedy on getting the best.

I'm still a newbie to this whole overclocking thing, so if somebody could explain it in simple terms, I would truly appreciate it.

What I want to know is which clock speed I could safely change the multiplier to, without having to change anything else.

Like basically, a clock speed which is guaranteed to work 100%, no problem at all.

I currently use an Antec KUHLER H20 620 as a liquid cooling solution for my CPU.

As well, how does RAM overclocking work? Thanks a bunch.

There are no guaranties when it comes to overclocking, but you might make it to around 4.3 to 4.5 GHz simply by changing the turbo multipliers.

I recommend that you read Sin's guide at the beginning of this thread if you haven't read it already. It may take some time for all that info to sink in, but you need to understand what each setting is for and how to set it. Patience is a necessity when it comes to overclocking.

Concerning RAM overclocking: Your RAM is rated at 1333. You might be able to crank it up to 1600 if you're lucky, but it might require a lot more voltage. The fact that you are using 4 modules means that it could be more difficult. Of course the performance difference between 1333 and 1600 is not that big anyway because the Sandy Bridge memory controller already has more bandwidth than most applications can effectively use. Going beyond 1600 brings little benefit.

Yeah, I've already read his guide at the front page of this thread. I understood a lot of it, and I do have the patience.

I just want to know of a speed I could probably jump straight to, without really worrying about changing any of the voltages or anything like that.

Is 4.3 GHz a good start, if I'm purely changing the multiplier? If that works I'll probably just with it, since 4.3 GHz is actually quite suitable for me.

And I see. Seems like my RAM's pretty much just going to stay as it is. Alright, no problem about that.

However, my G. Skills are quad-channel though? I heard that the GIGABYTE motherboards can support upping it via dual-channel? How do I use that?
