Digital PWMs can handle 5mv adjustment no problem, but it takes one HELL OF an analogue PWM to achieve that and there are only a few that can. Sadly they like to misinform, luckily they tried to bash me so i bash the living **** out of them when needed. They went as far as to send top OCers both Gigabyte UD7 and M4E, and everyone of those reviews were 99% negative on the UD7 and made it look like Gigabyte provided the boards.
These chips are good and everything but honestly its the MOBOS from gigabyte that are making them shine so well i think. I am very impressed with gigabyte.

Thanks for the guide. Just overclocked for the first time with F3 bios.

Capture Intel Burn Test by 77Pat, on Flickr

One thing I noticed is that VCore is 1.355 in bios, 1.32 when I started HW Monitor, and then 1.26 under load of the intel burn test. Is this normal?

Since I am using F3 bios I do not have the option to enable pll overvoltage. Although I am happy with this overclock so far. I will probably try the Prime95 Small fft test tomorrow.

I recently clocked my i7 2600K to 4,8 GHz. And i noticed that Windows still shows my clock as 3,4GHz in Windows, same thing in 3D Mark 11. Then i checked CPU-Z where it said 4,8GHz. So, which of them should i trust?

CPU-Z is showing the correct frequency. You can download the trial of Aida64 and run a few of its benchmarks which should also confirm the frequency CPU-Z is showing.

Also if you voltage is drooping like that you need to enable LLC.

Excellent guide! I used that a basis for my recent experimenting. I have a GA-P67A-UD7 and 2600K with a Noctua NH-D14 Cooler. I am using bios F6x.

I thought that I should share my experiences and get your guys opinions. I have come up with the following "stable" configurations. I am running my memory at 1066MHz so that I am just testing the CPU. That is the speed that my memory defaults to and is going to be replaced with some 2133 MHz RipJaws X anyways. To test stability I ran Intel Burn Test for 12ish hours under Maximum in Xtreme Mode.

For all configurations:
  • Turbo - Disabled
  • C1E - Disabled
  • EIST - Disabled
  • C3/C6 States - Disabled
  • CPU Thermal Monitor - Disabled.
  • PLL - Enabled
  1. 45x, BIOS Setting = 1.375V, Idle = 1.356V, Load = 1.296V, Temp = 60C
  2. 46x, BIOS Setting = 1.385V, Idle = 1.380V, Load = 1.356V, LLC 1, Temp = 62C
  3. 47x, BIOS Setting = 1.390V, Idle = 1.392 V, Load = 1.368V, LLC 1, Temp = 65C
  4. 48x, BIOS Setting = 1.35V, Idle = 1.368V, Load = 1.38V, LLC 2, Temp = 69C

49x seems unobtainable without cranking the voltage way up.

What are you guys thoughts on these for a 24/7 overclock? I obviously want to reduced to risk of burning this thing up within a year. I am leaning towards the 47x option, 48x seems to be running pretty hot.

Any thoughts are appreciated.
