Are these high temps for i7 4790k?

Hi guys,

Been trying my hand, or at least preparing, to try my hand at some overclocking. I'm totally new to this and been doing a tone of reading. I found a video that seemed good: https://www.youtube.com/watch?v=mBEeXajbG2o - which I've been using a guide.

So I found at around 1.15v on vcore and my system is stable. Which I'm using as my baseline. Anything from here on in means more volts. But before I go any further...

I did notice though in the video his temps never breach 60 and seem far lower most the time. I was a little worried that my temps were in the 70's for a lot of the test and core 1 hit 79 at one point. This seems rather high.. is it a sign something is wrong?

There is a setting I'm not sure on called vrin external override and I'm not if this has an impact on the settings im changing?

From a cooling point of view im using the corsair h105 with two corsair sp performance fans. Also the motherboard I'm using is the Gigabyte z97x SOC Force.

Are these temps concerning? (note the screenshot was at 1.2v I think, i found after this that I could go as low as 1.15v)

Any help or feedback appreciated - apologies if I've missed something.

they look ok to me

80c-85c is fine imo

Weird thing is, on the last stress test i did, i noticed in CPU-Z that the core voltage under massive load hit 1.5v - which shouldn't be possible if i've manually set the Vcore voltage to 1.15v?

Does this mean something is enabled that is overriding my settings?
 
There is a setting I forget but it does provide an offset iirc so it can go higher. I realise that is not helpful. Temps are ok as well, my 4790k was getting similar with an h100i before I de lidded.
 
Ok, ill have a read see if I can find the settings i need.

I was considering taking off the cooler and re-seating it on the cpu, with some good quality thermal paste just incase it's not as good as it could be at the moment. I dont like high temps, for a noobie, they can be scary

*edit***

Running a test at 1.1v at the moment and core is at 4.2. Only 10 minutes in but temps are staying around 50 / 60
 
That test you use uses AVX so it's already going hotter than anything you'll likely use for gaming! I really wouldn't worry. reset the temps, then play a game and see what max is after 30m, I think you'll be happy.
 
Bit of a buzz this, although Im sure that'll quickly dissipate if i bugger it up!

4.2Ghz looking promising

Hang on I'm confused, are you underclocking?

Overclocking? - initially i was under-volting to find a base line that the stock could run at comfortably, then begin to overclock up from lowest stable volts. What have i done wrong?

I just realized in that first screenshot that it says 4.4.. Hurmmm

Did you read that guide I showed you? If you haven't disabled the various C states then your CPU is still going to boost to 4.4 when under load. Mine runs at 4.6 all the time, you are aiming for something like that I presume :)

So try something like setting frequency to 4.6, VCORE 1.25 and use that as a base. Then if you can get stable on your tests drop the voltage bit by bit. I'm getting 4.6 at 1.170.
That's simplified mind there are a few other bits to tweak but guide covers it.
You can of course try setting higher, up to you.

Wrong link sorry, although still relevant, this is the one specific to your mobo: http://www.overclock.net/t/1490835/the-gigabyte-z97x-overclocking-guide

On OC Force you have voltage read points. Use them to check stable volts to CPU. Don't trust software. Its often incorrect.

Best way to stress is use your PC as you would normally. Then check temps. Mid 80's on that CPU is this heat wave is fine.

Thanks 8pack - i did notice at 4.6 cpuz was telling me volts were like 1.6 - is that just incorrect software readouts? I wasnt sure if there was something overriding my volts that id set
