4790k Overclocking Advice

danielbsipe · Feb 14, 2015

So I decided to start over clocking my i7 4790k. I just want to detail the process so far and get some opinions from some of you experts with more experience. I am an overclocking noob.

The set up is in my signature. I am using Aida64 to stress test and CPUID HWmonitor to evaluate temperatures. The results so far.

No OC: x40 multiplier, voltage auto
Max temps: 53c 52c 53c 55c

x42 multiplier, core voltage 1.141
Max temps: 62c 61c 63c 63c

x44 multiplier, core voltage 1.141
Max temps: 70c 70c 69c 69c

I ran the stress test for 45 minutes in both cases, and I was planning on not going passed 70c. I know the 4790k throttles when the T-case reaches 74c. Except, I don't know what exactly the temperature are recording from.

How long should I be running stress tests in order to properly validate an OC? What temps are safe? Should I push it any further?

Thanks for the advice,

45 mins. is plenty if you are testing the temps, later maybe try a little longer to test stability. I would recommend you try to go further, you have room until the Tcase + 5º more. Sou you still have room for more oc, and the aida 64 test is very stressful, so when you are gaming on doing anything else it wont get near the temps aida64 reaches..

The real question is WHY overclock? most programs/games you will NOT notice any difference at all, but you will shorten the life of the cpu.

nucolos :

Ok, then my next question is: Do i turn the Intel EIST on or off when OCing? Will it effect stability? What do you recommend?

computertech82 :

It is a good question. Most people over clock for the same reason you climb a mountain, "to see if you can do it" or "because it was there".

Not true tech, there are plenty of games and apps that will speed up from overclocking the already fast 4790k. Also i have overclocked every generation Intel chip since Core 2 came out, and have yet to kill a chip. They all lasted longer than i needed them to, and end up being hand me down systems. Overclocking is quite safe if you know what you're doing and don't push the chip too far.

Personally I keep my 4790k under 80c for stability testing. That gives you a bit of head room to try a multiplier higher or 2 if you're lucky.

I think i'll keep it at x45 with 1.140 voltage for now. In 45 minutes of Aida64 stress testing my temps were 69c 69c 70c 70c.

I disabled EIST because most forums I searched suggested doing so when overclocking.

If I scrape together the money to do some water cooling i might push it harder in the future.

Also, everything that i read indicated that i am managing stability at relatively low voltage.

Rule 1: Don`t overclock.

You don`t need to OC the 4790k because the IPC is already the fastest in the market. It is plenty in almost all that you are doing, considering that you are not rendering a whole Powerplant using CATIA or INVENTOR.

sportsfanboy · Feb 15, 2015

Rule 1? really? then why buy an unlocked chip? they are made to overclock, plus you can even buy a protection plan, so if you're an idiot or plan to abuse the crap put of the chip ,you can return it.

Your rule 1 is as absurd as why go to the moon

iamlegend · Feb 15, 2015

lolol, sometimes you eat and s*** sometimes you eat and think.

danielbsipe · Feb 16, 2015

So what's the deal with this thread? do you guys think I should not over clock because I'm doing it incorrectly, or because the chip is fast enough with out it? Honestly I expected better advice from Tom's.

sportsfanboy · Feb 16, 2015

don't listen to a member that comes into a thread titled Overclocking advice, and tells people not to overclock, it's called trolling.

your overclock looks fine, don't worry

iamlegend · Feb 16, 2015

lololol. you don`t get it do you? ^^

Rule 1: Don`t overclock - it will voids warranty and it might damage your chip.

If you have an i7 4790k and only playing games, you don`t need to overclock. If you wanted to test how far your chip can go, then overclock.

Rule 2: Overclock

Yeah, there is a 2nd rule.

sportsfanboy · Feb 16, 2015

Um please explain to me what the function of the i7 K chip is.

Wow just wow, i almost didn't respond, maybe I shouldn't have

iamlegend · Feb 16, 2015

Well as far as I used it, for making ICAD 2D ==>3D drawing. Using CATIA V6 2D==3D drawing. Which you have a vast information needed to be rendered in a single project, and will be send via DXF.

Industrial usage like, making cranes, ships, engines, cars, power plants and airplanes.

sportsfanboy · Feb 16, 2015

The K moniker is designed for one reason and one reason only, overclocking. If you have no interest in overclocking, you buy a non K chip.

As this was a thread with advice for overclocking a K chip, everything you said is non relevant I'm sorry.

iamlegend · Feb 16, 2015

lolol, yeah, non relevant for saying do not overclock the 4790k when gaming.

I should have said the Yes, overclock your 4790k up to 4.7~4.8Ghz because it is unlock chip and needed to overclock even when playing Far Cry 4.

Thus the statement above makes sense?

sportsfanboy · Feb 16, 2015

Now i'm intrigued... Answer me this please. Why buy a "K" chip? depending on your response i may or may not continue our discussion. At which point you can say you won, and proceed to glorious victory to the blissful state of the all unknowing.

iamlegend · Feb 16, 2015

Buy the unlock chip so that when the time comes that your system cannot cope up with the things you are doing, you have that extra capability to push it further.

In gaming, it`s like:

You need to eat 0.5 pussy but you ate 2 pussies.

In overclocking:

I already consumed 2 pussies but I needed more because I`m on the mood, it is a good thing I bought 2.2 pussies which can satisfy me.

Yes, you`re right, it will all come down into pussies.
