i7 2600k overclock (newbie)

post #1 of 15
Thread Starter 
I've done some reading about overclocking your CPU, and tried it myself, unfortunately it didn't go as planned. My absolute goal was reaching 4,8 GHz.

So this is what I did: I changed my Core Voltage to 1.35. I changed the core multiplier to 38. I changed the core frequency from 1000 to enough so I got 4,78 GHz. Ofcourse it didn't even boot my system, so that is why I am here. I have probably forgot about a list of things that needed to be done tongue.gif

Any help would be greatly appreciated!

Don't touch the base clock. It should be left at 100(1000) in your BIOS. Overclocking the 2600K should be done with cpu multiplier adjustments only, unless you really understand what you are doing.

You should go back and read again, because I have a hard time believing that any reputable overclocker would tell you to adjust the cpu multiplier to 38 and then get to 4.78Ghz using the base clock adjustment. Or that they would tell you to go straight to 1.35 vcore without taking multiplier and cpu voltages one step at a time.

Would also help to know what motherboard, memory, cpu cooling and power supply you're using.

Agreed smile.gif Do not change the Base Clock.

@Gerby, why won't you try 4.5GHz first? maybe start with 1.25volt and stress it then continue to 4.6, 4.7 and last 4.8GHz.
Straight to 4.8GHz is not quite good idea for first time use the chip in overclocking smile.gif

Note : Keep your memory at stock speed for better OC with your 2600K.

Gigabyte GA-P67A-UD3
8 GB DDR3 (2x4)
I've got a corsair fan (No idea which one)
600 watt power supply (need to look up the brand)

Thanks for you tips, will post again when tested.

Could you tell me where to start, and with how many to increase at a time? (multiplier and voltage)?

Another thing: The max multiplier is 42, which results in 4,2 ghz, how can I even reach 4,5? (Without changing core clock, of course)

That is a problem with your motherboard or your BIOS. Unlikely that it is a CPU problem because I've never seen a 2600K that wouldn't do 4.4Ghz with a cpu multiplier of 44, the correct BIOS settings and a decent air cooler.

Check the BIOS revision of your board. Likely needs to be updated.

Are you setting the cpu multiplier in the Turbo Settings or somewhere else?

You probably have a non-K chip, download CPU-Z and check what processor it says you are using. The non-K versions are locked at 42X max.

Yes, definitely. Sometimes I miss the most obvious of things. Very good point - you're probably right.
