Help: How to overclock Intel DZ68BC extrem motherboard.

post #1 of 18
Thread Starter 
Hello guys,

I'm sorry if this has been asked before, but I've searched high and low and still haven't found an answer. I have overclocked an AMD processor in the past and this is my first ever Intel build. I have an intel 2500K and DZ68BC extreme motherboard. I figured out how to change the clock speeds in bios but I have no clue where to go for the voltage settings. I attached an image file along with this. Noticed that I already changed my Host Clock Frequency to 119 because my core multiplier is 37, therefore putting my overclock to 4.4Ghz. Any help would be appreciated.

Bump. Anyone? So far I just did the automatic overclock at 4.5Ghz using CM hyper 212+ and it's using 1.408V according to CPU-Z. I'd really like to overclock this manually.

anyone at all? please help guys i am trying to figure this out but intel boards are confusing.

Those auto values suck!
I'll look for some details now...but start by using a 100mhz Host Clock Frequency. 119mhz is insane tongue.gif

What values can you set under Processor core? (Voltage)

Step 1:
Dont mess with your host clock.
If im not mistaken thats BCLK and you WILL corrupt your OS by messing with it(especially more than a few points).
Multi, LLC and Voltage, thats about all you need until about 4.6Ghz.
But you do not need BCLK.
Set it to 100 and start over.

Step 2:
Set voltage to 1.25 and your multi to 45. Run a quick stability test with prime, and bump voltage if you need to.
The closer to stable you get, the longer prime will run.
Once you narrow in on a stable 4.5, start working up to whatever speed you want, and then repeat the process.
Make sure to remember that as long as you have vdroop under control, you only really need to worry about multi and stability.
If you have trouble booting into windows juice PLL up a little bit and try again, and use VTT if you can log in but it hangs and BSODS on you.

Overclocking intel is basically like overclocking a Black Edition processor.

EDIT: As for voltage check under power or voltage overrides.

No LLC on that board, those are all the OC settings it has. Pretty basic stuff.

Thanks for the reply guys! I will definitely try it out as soon as I get the chance. I will keep this thread updated.

One more question guys. I went under processor overrides and changed the multiplier on all four cores to 44 giving me 4.40ghz. Under cpu voltage overrides, there are three choices: none, static, or dynamic. None is default. If I choose static, it let's me pick the voltage. Dynamic on the other hand let's me pick the processor core voltage offset. I am picking static for now and use 1.25v as suggested by philwrir. Also, should I set the vr droop to high vdroop for power saving or low v droop for maximum stability but puts more heat on the cpu?

Low vdroop for maximum stability, and set 1.25v and run prime95 small fft's. Run ram at stock for now.
Check temps, you should be below 85c at maximum load.
