How to overclock 2500k on Gigabyte z68 ud4 mobo?

post #1 of 10
Thread Starter 
Hello!

So I recently built a new computer and I need some help overclocking my 2500k.

I found this guide, link, on how to overclock the 2500k with a Gigabyte p67 board. I understand all the steps such as changing the clock ratio and other things relating to the memory. But when it comes to adjusting the voltages, this is where it gets a bit confusing.

On my z68 board, for the load line calibration, there are 10 levels to choose from, and I'm not sure which each one means. Also, what should I do to adjust the CPU Vcore, QPI/VTT voltage, and system agent voltage?

I want to achieve the highest speed that I can run stable, 24/7. I've heard that 4.5 Ghz is what most people clock their CPU; and I have a Corsair H60, so I don't think temperatures should be a big problem. I know that finding the right speed depends on the actual CPU itself, so I don't mind running multiple trials, as long as I know what I'm doing.

How many of you guys overclocked a 2500k on a Gigabyte z68 board? What settings did you use and what speeds are you getting?

Any feedback, questions, and comments will be appreciated.
Looking forward to your responses!

Hi , try this ive the exact same board cpu and memory as you and this worked for me @4.5ghz

Cpu clock ratio 45

then go into

enable internal cpu pll overvoltage
enable real-time ratio changes in os
disable c1e and all c3/c6 state
disable eist (this is not essential , but help me get stable)

set multi-step load-line to level 4
cpu vcore 1.35v
qpi/vtt voltage 1.1v

Thanks for the reply!
I will try this right now.

How would I know if its stable or not? Should I run Prime95 for some time and see if there are any errors?

Okay, so I've been running Prime95 for 15 minutes now.
My temperatures are around 60 - 66 degrees Celsius. Does that seem about right?

Hi.

Do not turn off anything saving power at 4.5 overclock. It's waste of energy. Be green. There is really no impact of every day performance at over 4.6 GHz.
4.5 is golden point of overclocking.

I can even turn max saving on at EnergySaver 2.0.

Memory i'm using is clocked 2133 MHz. Overclocks everywhere i'm seeing run memory at 1333 or 1600 at most to ensure stability.
For instance. 2600k scores 8800 '11 Marks without HT or with at 1866 memory speed.
At 2133 MHz DDR's score "hypers" to about 11000-11500.
That is impact i wanta to see, and that impact i can plainly see in games wink.gif

RARing file 2-3s faster is useless gain at 5.0 GHz and killer voltage wink.gif

Try my setup:

FREQUENCY PAGE:
Normal multiplyer: 34x
Overvoltage: Off
Changes in OS: Off
Turbo: 45 at all four rows
TDP: 150W
Savings at bottom of that page: all enabled not auto

VOLT PAGE:
Vcore: normal
DVID: +0.050 (actual stable, prime all night test several times, but it can be lowered, im sure, and would try till any instabilities with working EnergySaver occurs)

Would you try green way? wink.gif
