i7-4790k + (what cooler) = good OC?

[manofthem]

A 4790k should hit 5ghz on stock hsf; their tim is much better than earlier cpus

[Kursah]

so we can say that running my 3770k to 4.5Ghz and 1.25v is safe?

That's great. Also you don't have Haswell, which is the CPU family that Onemoar is referring to.

The 4790K is 4.0GHz stock and 4.4GHz stock turbo, generally at 1.25-ish voltage. Reaching 5GHz might happen if you have a good chip, a really good one.

I am able to run around 1.16-1.18 atm...seems stable, but not 100% sure it's 24/7 ready yet.

Edit: @manofthem

The 4790K I have seems to run a touch hotter than my 4770k did...and that's on a Noctua U14S..the stock cooler with this chip would surely hit close to the thermal throttle point of 100C under an OCCT load. The TIM is supposed to be much better...and I do plan to shoot for 5GHz to see if I can pull it off at sub 1.30v...but I have my doubts. This is just one chip though... I am sure many are capable of hitting it, but there's still the silicon lottery.

My goal is 4.5Ghz with the lowest voltages

1.23v for 4.5Ghz is solid man... my 4770k could do it with 1.25v. I wouldn't worry too much at that level, if you can keep your temps below throttle and voltage at an acceptable level (below 1.35v, or as some would prefer, 1.30v, I prefer 1.30v btw)...then call it good. Do yourself a favor and see if that OC is even worth your time though. Even with your slightly older CPU, you might not receive the gains you expect beyond just having a higher CPU turbo clock speed.

setting voltage to 1.30v i can hit 4.9Ghz and temps stay maximun 60c just when using some stability test, Linx, prime95 on so on.

is worth to have it at 4.9Ghz 1.30v rather than 4.5Ghz 1.25v?

That's a question you can totally answer yourself, and really only you can. Do you feel you need the faster clocks? Why are you overclocking in the first place? What is your goal?

Why not take a couple of your favorite games, load a good save where you can reproduce a sequence of events and run Evga Precision or similar with FPS OSD (On Screen Display) and see?

Honestly, once you start going past a certain point, your return will be reduced, your power consumption will go up, and noticeable performance increases will cease to exist. I don't see a point...but running that cool and even at 1.30v, that's a nice OC. If you were running 3-4 cards in CFX or SLI, and was doing A LOT of CPU heavy stuff, I'd say maybe that OC would be worth it.

I honestly wonder if you'd notice a difference with stock vs. your current OC. Maybe you could run some tests to verify. I don't mean 3Dmark, or benchmarks, but things you actually do with your PC.

can't we not derail the ops thread

 

[Kursah]

Sure thing boss.

 

[Smigze]

So I should just focus on OCing the GTX 970 and leave the CPU alone to increase gaming performance?
How loud is the stock fan for the 4790k? Because my AMD Phenom II X4 965's is loud as hell.

Why worry about OC-ing in the first place?

If you research you will see both the CPU and GPU have Turbo modes...that is...factory OC-ing, supported out of the box.

My GTX 770 is stock, and runs ALL my games smoothly and MAXED out at 1080p.

What are your goals here? I recommend you put it all together and run it stock, see if you even need to overclock in the first place. The stock Intel coolers aren't too noisy, but aren't very effective...I recommend an aftermarket 92mm or 120mm fan tower cooler (I usually recommend the Cooler Master 212 EVO... an affordable and effective air cooling solution).

If you feel you need to increase gaming performance, which for most is usually FPS piped to the screen, then yes, the GPU is what you should target. Also keep in mind that drivers can have quite an impact on games as well. And overclocking GPU's also leads to extra power consumption, heat creation, and louder fans. My Gigabyte with the cooling solution it has is great, but gets noisy above 80%.

5ghz is not guaranteed, stop worrying about ocing and enjoy your spoils

Ha I got a 4790k that uses just 1.040 @ stock
1.18 @4.6ghz
1.20 @ 4.7
1.28 @ 4.8
1.3785 @ 4.9
1.50 @ 5.0

And its water cooled and at 5ghz she's in the upper 80's

Good luck op and have fun trying for a 5ghz clock.

Oh and a 3770k at 5 GHz is not as fast as a DC at even 4.6-4.7 GHz...

I've had 2700k @ 5.4
A 3770k @ 4.8-4.9
There was a close match clock vs clock but sorry a 3770k is no where as fast as a 4770k or DC chip...

Wanna play ?

4790k
1.18 @4.6
1.20 @ 4.7
1.28 @ 4.8
1.3785 @ 4.9
1.50 @ 5.0


3770k
1.18@ 4.6 (no tested it)
1.25 @ 4.7 (i have to test lower voltages)
1.28 @ 4.8
1.30 @ 4.9
1.38 @ 5.0


The 3770k its water cooled too and at 5ghz hit maximum 65c just under stability test.

 

[fullinfusion]

Yes that's what the bios reads off the chip.

Its a great chip and its going to be a sad day when I have to sell it. There's so many deeper bios over clocking settings to hit 5ghz on this chip that I've never seen before.. There's the normal extreme settings page but within that page there's a tweakers Paradise where the secrets lay in over clocking beyond the norm.

Have you or does your chip support boot strap options? Like 125/150/200/250 bus settings?

I've had great luck using the 125 boot strap setting with a 40x multi for 5ghz. But a 50x is a no go. I can boot into windows but it can't run any type of stress test but the bootstrap change and fiddling with the tuning Paradise page settings work well. Winter is so near that I'll be shooting g for over 5ghz

okay, so tomorrow I'm gonna start building my rig and 4K is my goal. The 4770k stock with boost should be enough to handle 4K? I'm sure my gpus are more a determining factor, but I thought you'd want everything bawls to the wall for 4K? I'm wondering if I'd need to invest into a better cooler for higher clocks?

You need best cooler possible. Not the place to try to save a few pennies, if 5 GHz is possible. Cooling may not be the only limit. You want guarantee 5 GHz, try phase-change or LN2 cooling.

 

[Nabarun]

I agree with @Kursah about little benefit to gaming from OC. The only people who actually benefit from oc are the ones who do a LOT of rendering in multimedia apps. I do it just for fun. My H220 is good-enough for the VERY HOT 4670K I got, but it's not the temperature which holds it back - it's the insane voltage requirements. Currently I'm running it at undervolted stock with all the power-saving stuff enabled. Only a good GPU can make a significant difference in gaming, so invest on that. However, if you want to have some fun with overclocking, and you don't want to go full custom loop water cooling, the new Swiftech H220x and H240x can be a safe bet, and they look incredible. Not to mention very quiet operation.

Take note of what @Kursah @eidairaman1 @fullinfusion @cadaveca and i posted above, in order to have a better idea of what you want to do and which are the advantages and disadvantages.

I don't know what are your purposes to overclock to 5.0Ghz , 1- just for fun?
2 - gain performance in games? if the second one is yes than you have to read what we posted above carefully,
i dont see the needed to run a machine 24/7 at 5.0Ghz fixed If that's what you mean to do, I hope I am wrong.

Example:
I did Overclocked my 3770k at 5.0Ghz 1.38v but that was just fun and nothing else, now I am running my CPU at 4.5Ghz dynamic OC, why dynamic?
in order to give a break to the CPU and not be running at full speed even when it doesn't need it.

You want guarantee 5 GHz, try phase-change or LN2 cooling.

Why phase-change or LN2?
We can get high overclocks with Aircooler or Watercooler too, am I right or wrong?

Sure, but you should really only expect 4.6-4.7 GHz for 24-7 longterm use on average. You can always push voltage to dangerous levels and then use the Intel Tuning plan to RMA and get another CPU. It's only $25, and is basically a "no questions asked" replacement policy (physical damage does not apply, damage from OC completely covered).
