I'm completely new to overclocking and have no idea where to begin. I've watched a few videos but am still unsure of how to go about doing what I'm after.

Specs: evga GTX 760 Dual FTW 4GB (x2 sli)
i5 4670k
16gb ripjaw x series @1866
maximus hero vi
seidon 240m liquid cpu cooler
thermaltake tr2 rx 750w ps

Basically I just want to hit 4ghz which from what I've been reading shouldn't be hard but I'm sketchy on trying for 2 reasons.

A: people are saying you should check your components before you try to overclock like running a cpu stability test and memtest passes? I have no idea what this means or how to do it.

B: Can my system safely handle such an overclock?


To make a long storey even longer, I'm just a gamer with a new rig (the power supply is a carry over from my old rig) looking to get more out of my set-up and would love any help that you kind folks could manage to give me.

With that cooler you should be able to hit 4.5 or higher if your gpu's arent heating up your case too much. With only a 750 watt psu, i would only oc the processor and not touch oc'ing on the gpus.

literally all you have to do on the hero is select one of the premade profiles

otherwise just increase vcore to say 1.2, then increase core multiplier from stock (should be like 34 or 35), to 40, then stress test with prime 95. overclocking is easy, and your components are just fine for it. Linus from tech tips does a good job, and tutorials for your specific processor and motherboard overclocking are also easy to find. just google 4670k and maximus hero overclocking and there are lots of tutorials. if you don't increase voltage past 1.3, and dont get temps of over 90, you are doing no harm to your system. though you should aim for under 80c even under load (with a 240mm water cooler this wont be a problem only going up to 4.0)

A: You will need 2 programs real temp, and prime95. Start up real temp and watch your core temps. Then start up prime95 and do one of the tests, I use small fft's because I'm not worried about ram. Make sure temps aren't going over 80. After that increase your multiplier setting in the bios to 40, your vcore to around 1.2, and since you're using a maximus type motherboard make sure that "Asus Multicore Enhancement" is off otherwise your cores will permanently run at turbo speeds which is not really preferable. Do the same thing with real temp and prime95. If you don't have any blue screens after a couple hours it's probably stable and you can try decreasing the voltage until it becomes unstable. If it is blue screening increase the voltage until it's stable.

B: There's a always a risk, but intel sells K series processors with a warranty for a reason, so if something does happen you'll able to get it replaced. Note, there's also a risk I'll slip and die getting out of the shower everyday but I do it anyway because I like bathing.

When I go to the ez bios and select performance mode the system crashes when it tries to load windows and when i set the values myself it's only showing the turbo speeds changing. Is that all I'm aiming for? changing the turbo and not the base speed of the processor?

typically when overclocking you want to turn turbo off completely

Fwah? Why would you want it to run at maximum all the time? That doesn't even make sense. You want turbo to be on so that you can use less power, produce less heat, and get the same clocks under load. If you're not taking advantage of that... I don't know what to tell you.

Yes, i7's are very easy to OC, increase the multiplier to where you want it then add voltage, the only real consideration is getting rid of the heat. If you go over 90c it's going to start going into emergency shutdown mode so avoid that. 75c is about the most you want under full load i.e. prime95 tests.

i just found an option to which auto set it to a 4.2ghz overclock and prime 95 is running now, so far it's hit 76 deg (package) 75 deg on the 3rd core as a max. so what you're saying is i want to leave the base @stock 3.4 and i'm just concerned with the turbo overclock? sorry for my noobishness, this is completely new to me.

All guides i have seen say to turn off turbo for stability, and for myself i had no troubles over the last year with temps running my processor at max speed (max speed does not translate to max load, and if you look at any overclocking benchmarks, no matter what you do, even idle temps are higher after overclocking) at all times, just set the vcore to drop when not under load and this removes the heat problem

Adaptive mode does just that but it doesn't work right if you're not letting the system clock go down which is what I'm getting at. Maximus boards have a turbo adaptive voltage, so you can actually let the voltage change depending on the C state of the cpu which is great. Anyway yes I know having the clocks at a constant rate doesn't equate to the same as max load, but the way it used to be was you always had to have it do that. Ever since they came up with EIST and Turbo you can allow it to slow down when not in use which is saving power overall and creating less heat. If you want proof that lower clock speeds create less heat, just leave your voltage where it is and drop your multiplier.

Back to the OP, yes that's exactly what you need to do. I was going to suggest using one of the presets. They aren't as efficient as doing it yourself but they do work for the most part.

well after a couple of hours of prime 95 I've had no errors and the max temp hasnt gone above 77 deg. so i basically have just one more question. ive read that in some cases the the cpu actually gets over volted(from what ive read mainly when using synthetic tests) when using auto settings. is this something i should be concerned about? my pc's workload pretty much exclusively consists of gaming and 'regular pc activities' (ie facebook, email, movies etc)

That would only happen in some benchmarking programs if you're using adaptive mode for your voltage. So no that's nothing to really worry about. For the most part systems are smart enough to reduce settings automatically before major damage is caused. And again, warranty.

Thanks for everything folks, running stable @4.2, once I read more and understand more I'll probably push it further for no better reason then because. lol. Cheers.
