The Ultimate CPU Overclocking Guide!
Visit www.custompcreview.com for more reviews, unboxings, and tutorials! Please subscribe if you found the video helpful! **EDIT** Ive now successfully tested my own machine at 4.4GHz and I can confirm at least for my chip that it is completely stable using this method. The idle vCore is around 1.04v and vCore under full load is 1.28v. **Correction** In the video I refer to the P67A-GD65 as P67-GD65. I actually meant to say P67A-GD65. Easiest method of overclocking the new Intel i7 2600k using the new MSI B3 stepping P67A-GD65. I overclock it to 4.2ghz, but it may be overclocked to whatever your CPU and the CPU cooler is capable of. ***Disclaimer*** I take no responsibility of anything you do with this guide. If your computer blows up, its not my fault!

2500k too?
do this work with a intel core i5 2400k quad core.
So should I try to copy ALL of your settings before testing on my own?
4.2 at 1.28 volts? my 4.2 ghz is running at 1.22 volts. try it
You just change the value and thats it lol?
@custompcreview Thanks. I happen to have just bought these exact models of CPU and motherboard this week.
You answered exactly the question I had. I figured out that it’s easy to overclock using the method you demonstrated, but I wanted to be absolutely sure that the voltages adjusted automatically to the overclocked speeds before I tried it out on my brand new rig. Thanks.
@weropfermag and yes, at all cores, if you copy the settings.
@weropfermag This is the safest and easiest way to OC. Yes, you right. Its dinamic, When you gaming hard, its goes down to 4ghz, when you idle, its go down to 3.4. So it’s the most safe and powersaving sulotion.
@weropfermag In my experience the cores don’t use 3.4ghz anymore. Its either 1.6 @ 1.04v or 4.4 @1.27v (your numbers will vary). If you think about it, there’s really aren’t any processes that won’t run faster if you throw more processing power at it so why would your cpu ever choose to run at 3.4 when it can run at 4.4? If you have voltage control in auto mode, voltage will automatically change. If you push your oc too high, auto volt control won’t work though. In my experience it’s 44x
how much V is on the cores when they are in normal mode (3,4 ghz) and how much in Turbo? Does the cpu automatically increase the voltage it needs in turbo mode?
so you oc only the turbo boost on all cores to 4,2 ghz?
does that mean,when the cpu is in normal usage its only 3,4 ghz? and when it needs more power it goes up to 4,2 ghz at all cores?
@UberTroll13 spam the delete button right when you turn your computer on
how do you open the bios
@custompcreview No, it really is 2600K lol, guess the mobo has set wrong defaults. At least BIOS and CPU-Z and Intel box from which I took the chip out says "i7 2600K"
@Dex1n Yeah, I haven’t really used the Gigabyte boards yet, but I’m sure it should be a similar process. The 2600k should be at 38x stock though.. you may have gotten a bad chip or the wrong one or the mobo defaulted to the wrong settings.
@custompcreview lol, I know 2600K’s default turbo should be 3,8GHz right, however, my 2600K’s default turbo is set at only 3,5GHz
Using Gigabyte p67a UD4 board.
@iPojHD Hey sorry for the late response, but basically speaking voltage is a part of what gives your computer electricity to run. In theory, it should take more electricity to run a faster computer which is why you’d change voltage to increase speed. With this mobo there is a feature for automatic voltage. Unfortunately if you push the turbo multipliers past a certain mark, it may become unstable using that feature. If you want to OC past that point, you then have to manually set voltage.
In what cases would you need to change voltage and can you please explain what it is and how it works?
@metsfinest15 Yeah I started out overclocking this processor the old way, but my processor ran 24/7 at 4.2ghz so this is way better as it allows you to run the CPU at 1.6ghz when not in use, but have it clock up to 4.2ghz when in use saving you power and increasing the life of the processor. Just as an update, I used this method to sable overclock my CPU to 4.4ghz so if you’re feeling lucky you may be able to get 200 more mhz out of your 2500k
okay cool thanks man, because my i5-2500k is oced to 4.2 but the ratio limit was like on 35 36 38, so i changed all of them to 42
@metsfinest15 By setting the ratio limit to 42, you’re increasing the turbo limit on your cpu. From the factory, a i7 2600k naturally overclocks itself to 3.8ghz using turbo when its needed which is why it’s set at 38 to begin with. By setting it to 42, we can change that factory limit to 4.2ghz thus overclocking it.
but putting the ratio limit to 42 what did that do exactly?
