A little help OCing a 2600k to 4.0Ghz

post #1 of 3
Thread Starter 
Hey guys. Here's my system:
DEEPCOOL DUKASE BLACK CASE
INTEL I7-2600K QUAD-CORE 3.4GHZ CPU
KINGSTON 16GB DDR3 1600MHz RAM
GIGABYTE GA-Z68XP-UD3 MOTHERBOARD
NVIDIA GEFORCE GTX 770 2GB DDR5 GPU
INTEL HD GRAPHICS 3000 GPU ON-BOARD
CORSAIR 120GB SATA3 SOLID STATE DRIVE
TOSHIBA DVD R+/-W DRIVE TS-H653
TOSHIBA DVD-ROM DRIVE TS-H353
WESTERN DIGITAL 1TB SATA GREEN HARD DRIVE
WESTERN DIGITAL 1TB SATA BLUE HARD DRIVE
CORSAIR H100 EXTREME LIQUID CPU COOLER
OCZ ZT SERIES 650W POWER SUPPLY
WINDOWS 10 X64 PROFESSIONAL

I've seen a lot of people OC the 2600k with this motherboard to 4.5 and above, but I want to go with 4.0 just to be safe. Can anyone give me the appropriate BIOS values that I'll need to be changing to get it around a stable level at 4.0?

Stability isn't guaranteed by settings alone. You have to test the stability of your system after you overclock the CPU in order to know whether it's stable.

 

Anyway, for 4.0 GHz, all you probably need to do is set the multiplier to 40. After all, this is only a 200 MHz overclock (3.8 GHz to 4.0 GHz). So, it's really nothing and you won't even notice it or feel it. 4.0 GHz is nothing like it was back in the days when the stock clock speed of CPUs was maxed out at around 3.0 GHz. Today, 4.0 GHz is hardly even worth the time or effort (not that it requires much time or effort to accomplish a tiny little overclock like that).

 

With your system, you should be able to achieve 4.5 GHz very easily and it's still a safe overclock. I don't have enough time at the moment to help much more than this because I'm about to sit down to a big meal and then I have plans to clean the house immediately after (gotta eat some fuel before I work lol). So, I'm going to be gone for a while. However, overclocking Sandy Bridge is really just a matter of adjusting the multiplier and the core voltage.

 

Edit: Why is your list of specifications in all caps? Did you have this build pre-made by a custom computer builder online?

I have an overclocking profile for my wife's computer set for 4.2ghz @ 1.196v (actually an undervolt) on an i5 2500k. While not the same chip, I imagine you can easily hit 4.2ghz at stock voltage (or a slight bump up).
