Need help Overclocking!

I've looked all over and haven't found anything simple on how to overclock. I have an i5-4670k and an MSI Z87-G41 motherboard. I have two things I need to know;

There's an OC genie button in the bios but I don't know what voltage and frequency it will use but I heard it uses way more voltage than necessary and I'm using air cooling. I've looked in the manual but it provides no information on what exactly it does other than if you're inexperienced, use it.

If I manually OC, how can I make it so that idle temps and voltages stay the same but it turbos to a higher frequency and voltage adaptively without giving itself too much power. I want adaptive but want to set the max freq. and voltage. What settings do I need to change to do this? Do I just set the ratio and voltage and set it to adaptive? Will it be smart enough not to go over the voltage I set?

Thanks!

Then, in the BIOS/UEFI, you want to enable the following:
- Adaptive Vcore voltage
- Intel Turbo Boost
- Enhanced Intel SpeedStep Technology ("EIST")

In Windows Advanced Power Profile select "Balanced" setting instead of "High Performance".

With Vcore set to adaptive, it is possible for the CPU to override the max voltage that you have set by as much as 0.10 to 0.15 volts. This can happen in AVX Instruction Set heavy apps, like Prime95 and Intel Burn Test while stress testing. For this reason, you should always use "Override" Vcore Voltage setting while stress testing to avoid these voltage spikes.

Having said that, I use "Adaptive" the rest of the time and a "Balanced" option in Windows Advanced Power Options and my CPU speed and voltage both throttle back nicely when my CPU is lightly loaded.

Here is a thread that helped me a lot when I first started OC'ing: http://www.tomshardware.com/forum/id-1722630/intel-god-quick-dirty-guide-4ghz-haswell.html

Additionally, the CD which came with your mobo should have a program called "MSI - Intel Extreme Tuning Utility" (IXTU). I find this program to be really handy for monitoring my CPU and making quick adjustments to many settings without rebooting into the BIOS. IXTU doesn't have any "auto OC" feature. You still have to add your own changes but it just makes changing settings faster and easier. Highly recommended!

Its not recommended to overclock your computer.It will lead to warranty void and maybe your computers lifespan will be shortened. and maybe result damage to computer.

I'm just warning you im not saying you must not overclock just you to know what can the price be for that.

When you go back and set it to adaptive, how can you be sure that it won't add more voltage than it can handle when it's under load again (lets say heavy gaming)? Assuming you set the voltage to the maximum it can take to get the highest overclock possible? Do you just have to go a little further away from the max voltage to allow for voltage spikes that are still in safe boundaries?

Also, can I just change the Vcore and multiplier and leave the ring bus and other stuff alone? I don't know what that is and different guides tell me to change different things but they all have the multiplier and Voltage in common. If possible I'd like to only change thise two things. Can that be done? I'd probably start with a 40 multiplier and 1.15 - 1.20 volts. Does that seem good?
Thanks!

slowly increase the multiplier and run stress test, until it crashes.

Then slowly increase the Voltage offset until lit doesn't crash. Check your temps and core voltage all the time when stressing, that way you'll know the max V and T when stressing. Don't rely on the mobo to know what V to set for a certain clock.

Note: your system might die. It might protect itself from high temp, but not high V.

So I can leave all the other settings alone then? When I set it to adaptive, how do I prevent it from drawing too much power since it will be done automatically at that point?

 


I wouldn't use "Offsets" as they are just too confusing and they increase the Vcore across the whole spectrum of load/frequencies, so, even at idle, the CPU will be applying the Offset voltage increase, which is totally unnecessary. Just work with the straightforward Vcore settings directly, and the CPU Multiplier.



With "Adaptive" setting the max voltage is selected by the CPU, not you. The only way to avoid this is to use "Override" which is a fixed voltage setting.

I read somewhere that someone said there were able to use adaptive and after overclocking, the OC was essentially the new turbo boost. So the isle voltage and temp stayed the same as before the OC and when running a demanding program, it went up to OC speeds and voltage. That's what I want to do.
 


Then, in the BIOS/UEFI, you want to enable the following:
- Adaptive Vcore voltage
- Intel Turbo Boost
- Enhanced Intel SpeedStep Technology ("EIST")

I think I found what I'm looking for here in the last post;
http://www.overclock.net/t/1400325/how-am-i-doing-so-far-4670k-result-and-adaptive-voltage-question

Can anyone confirm that info? Apparently I should use manual when stress testing but then set it to adaptive after, and it won't go over the voltage I set since nothing is more demanding than the stress test.

Lastly, lets say I under volt it and I can't get it to boot. How do I get back into bios? I have an MSI Z87 G41.

EDIT: Ahh, you ninja'd me :)
