Overclocking i5 2500k with gigabyte mobo-not sure how to start

I am extremely new to overclocking and have no idea where to start.
These are the parts i have

Cpu: i5 2500k
mobo: gigabyte ga z68ap-d3
ram: patriot 8 gb 9 9 9 24 1.65 volt(yeah i know i shoulda bought 1.500 volt)

So i read the guides on tomshardware. However I didn't understand them. The cliffnotes one went over the information too vaugley for me. The full one uses msi terms and I have a gigabyte board. I have no idea what term relates to what. So I am asking for help from anyone that knows gigabyte terms. It would be greatly apreciated.

Btw i tried just changing the multiplyer and i got the can't boot message because of overclocking or undervolting. Any ideas?

    What speed are you aiming for? What cooling do you have? Read this guide: http://www.tomshardware.com/forum/266189-29-sandy-bridge-series-ocing-cores-guide Just use those values, it is all the same just in a shiny new UEFI format.
  2. I have a hyper 212+

    and i am aiming for 3.7-4.0 I don't wana ruin the life span of it. To me its more about cooling than it is about speed.
  3. Set the CPU multiplier to 40 and go with it. You won't need to mess with voltage for that low an o/c. The UEFI won't even let you save an invalid CPU speed or voltage.
  4. so why is it when i tried that i got the can not boot because of overclock message?
  5. I'm lost. You say you're more interested in cooling than speed so why are you over clocking at all?
  6. well i just want the best combination of the two. I don't want 4.5 gh but i want more than 3.3 3.7-4.0 is right in the middle
  7. Adjust your ram voltage to 1.5v. (Triple channel sticks, but they run in dual channel for me! I've got them too, at 1.5v) Anyways, as for your cpu try 1.2v for voltage. If it boots, run prime 95 or OCCT for a few hours and leave it. You can also try reducing the voltage by .005 until it crashes and increase it a bit until it is stable under booting, stress testing, and gaming :)
  8. First, go buy another set of RAM, 1333Mhz @1.5v according to Intel i5-2500k's specs.
    Reset your motherboard bios (optimized default settings inside bios)
    Reboot to bios again
    Turn off Intel TurboBoost then set multiplier to x40
    You're done.

    Extra configuration for cooler system:
    Set CPU Vcore to normal then Adjust your DVID (dynamic Vcore) to lower (-0.075V or so) because at 4Ghz, the i5-2500k won't need that much voltage.

    I really don't think i need a new set of ram

    Tried 1.2- computer got stuck in a boot loop- guna let it run at 1.3 where it is stable now


    I have it overclocked and shut off turbo boost but for some reason it still acts like its enabled- it only gets 3.7 when its under a heaver load- other than that its 3.3

    Did you follow the guide? Also lower the 1.3v until it starts crashing, and then raise it a bit.

    yes but why is it its still only going to 37 at heavy load- is that normal?
  13. its weird- I got it to work by just changing the turbo multiplyer nothing else but when i tried following the guide it got stuck in a boot loop.
  14. btw at 40 turbo (4.0 gh)

    I have 27-30 idle

    and and high 40s low 50s (55 is highest right now) at prime 95. I am assuming thats good right?
  15. Good temps.
