First SB OC

[Youngie1337]

Hi guys, can someone point me in the right direction of OC'in my 2500k?

My D14 arrived this morning, and I'm going to install today when I get some free time. I am wanting to OC my 2500k as far as it'll go & be stable.

I have

Sabertooth P67

i5 2500K

HyperX 1600 8GB

700W Coolermaster PSU

Can someone either give me the settings to get the best clock or push me along the lines of OC'in this beauty.

I've not overclocked since Q6600, and that was when it was released 2008'ish.

Thank you very much!

Hi Mate.

My 2600k OC was my first OC and I read a few guides before starting my OC. Below are the basic steps I took to get a basic 4.0GHz OC and these steps can be applied to achieve a higher OC. I am by no means an expert and there may be other settings that could change to achieve a higher OC. I'm hoping other experienced members can improve upon what I have to say

.

1. I went into my BIOS and went into the "Advanced BIOS" settings.

2. Next I went to the "AI Tweaker" section and changed the "AI Overclock Tuner" option to Manual.

3. Then I typed in a number corresponding to the overclock I wanted. In my case I typed in 40 in the "By All Cores" section for a 4GHz overclock (BCLK/PEG Frequency * Turbo ration = 100.0 * 40 = 4000MHz = 4Ghz).

4. I left the memory frequency to Auto because I wanted my CPU overclock to be stable first. Alternatively you can set the frequency to 1333MHz, which is the default for most or all DDR3 DIMMS.

5. Next you have to set the voltages. The "CPU Voltage" option has to be set to the "Manual Mode" to allow you to type in what voltage you want to use. If you want a 4.5GHz overclock then use a Turbo Ration of 45 on stage 3 and set the voltage to something like 1.25V.

6. Set the "CPU PLL Voltage" to disabled and boot to Windows.

7. Finally I used prime95 to check if the overclock was stable. I tested my CPU for at least an hour before deeming it stable. If the prime95 test shows no errors then you can assume the overclock is stable. If your OC is not stable you can repeat step 5 until you have a stable overclock at the lowest possible voltage. I ran prime95 for about 10 hours after I had finished overclocking to ensure the stability further.

NOTE: These are the basic steps on a p8p67 pro motherboard, but I am assuming all of the Asus p8p67 Bioses are the same.

Finally I set the timings and frequency for my RAM as stated on the RAM modules.

Again, that's a great method to follow. You can also try out OCCT or LinX to really stress the CPU to test stability.

You can also disable the enhanced power features, Intel Speedstep/Turbo Boost options. That's if you want to have the CPU running at a constant frequency without it downclocking whenever the system is idling or being inactive.

Yep, I agree.

Thanks a lot for the information mate, the D14 is mounted now, and some cores are as low as 27c

, wow it's a huge beast!

Ofc I know it's all about load temps, so time to do that now

That's awesome mate. I bet it was a doddle mounting it. I'm considering getting it to OC my CPU further, but I will also have to get LP ram.

Yeah I got HyperX low profile stuff, went for the 1600 in the end as so many people suggested the 8GB for half the price of 4GB @ 2133.

Max temp running Prime95 is 50c on hottest core, so, awesome cooler! Hopefully be able to get this CPU @ 4.5, I'm aiming for it lol

.

The mounting wasn't hard at all, it's just push through holes screw, then screw again, simple

. Was a bit of a pain when I put the board in case and trying to connect power to mobo, it was such a small gap, I completely underestimated the size in the case

. Had to take the mobo out again, which was a quick job, but wasn't expecting to not be able to plug in the power cable & fan

.

See you in an hour or so

, wish me luck lol.

Good luck mate

Good job there. Hope you'll be able to get the 4.5GHz OC to stable. What's the chasis that you're using currently?

@4.2 stable atm, hopefully I can get to 4.5.

Very nice. Did you paint that yourself? Somehow it looks similar to the classic In Win server chasis.

SB OC'ing is so easy, multi x 45 and start at 1.35v and the lower or increase the voltage
