i5 4670k 4Ghz @ 1.080v - 4.2Ghz @ 1.180v( Did i get a quality processor? )

[Ephesius]

Hey guys, i've been testing my CPU for couple of days now. ( Asus Z97-AR Mobo )

Im running Aida64 Stress test and my system works flawlessly with the given settings on the title.
Not getting any WHEA erros.

Games like BF4-Shadow of Mordor runs smoothly without problems.

After 8 hours of Aida64 testing, temps are below 60 mark with average of 50-57 celcius per core, with custom fan profile on Hyper 212x ( Arround 800 Rpm Average )

I can easily run my processor at 4.2Ghz with 1.180v with 59-67 celcius average per core. (Tested 8 Hours and Gaming aswell) ( 980 Rpm )

So the results are;

i5 4670k 4.0Ghz OC - 1.080v 50-57 Celcius with Hyper 212x (800 Rpm)
i5 4670k 4.2Ghz OC - 1.180v 59-67 Celcius with Hyper 212x (980Rpm)

Both results are from 8 hours of Aida64 %100 Load Test.

I like to run my fan Rpms low to have dead silent load noise. I am able increase them about 200Rpms without much noise and drop my averages about 3-5 celicus aswell, but it seems unnecessary.

My memories are running at 1866 Mhz 9-10-9-27.
Cpu Cache on Adaptive
Cpu Input is @1.74v ( I didn't change it )

Do you think i got a good processor?

( Never touched to other settings when OC'ing, Only Ratio and Cpu Core voltage )

Are you sure it will not be stable on a lower Vcore than 1.18V for 4.2Ghz OC? Seeming your 4GHz VCore, I'm certain you've not yet determined the lowest stable VCore for 4.2Ghz on your chip. Manually lower the Vcore by 0.05V and check for stability, and when it crashes or freezes, up the Vcore by .01V and that shall be lower than current 1.18V.

But anyways, it looks like a fine CPU to me, how's the VCore at 4.5Ghz?

Not sure about your question, but YAY MINIONS.

@MeteorsRaining, Well i did got an instant crash on stress test at 1.150 (First Try) @4.2 so i never tried lower than 1.180 to be honest. I do not want to OC my processor at 4.4-4.5 mark atm, but maybe i will give it a test later on. But i assume i will achieve 4.4@ 1.250v +-, not sure about 4.5 since its like the most you can get with an average air cooler.

@AdmiralDonut YAY MINIONS!

Your temps are not an issue, but I don't see any need to provide the CPU with extra VCore if it's fine with lesser than that. Don't assume VCore for a particular OC, do not increase it when you increase multiplier. Only if the system is unstable is the time when you should increase VCore. They're not pre-built settings which you can just apply.

My advise? Start from 4Ghz @ 1.08V, and increase multiplier by 1, keep VCore as it is. Then stress test, if it's unstable, increase Vcore by 0.05V and test. When you're stable, go higher. I'm certain you can get better VCore.

1.070, gives me crash, not when testing but when i try to use chrome when testing. so i guess 1.080 is a good Vcore for me with a bit of headroom, 0.001 wouldn't change a lot i believe since it was already working higher than what i use for 4.2Ghz at adaptive Voltage. A quick OC to 4.4Ghz with 1.255v, seems like stable for 15 mins, and temps arround 66-71 mark. I can stabilize at 4.4 thats for sure, I don't want to go above than that. ( Im quite noob when it comes to OC since this is my first desktop rig and i have it for only 2 weeks )

And i will be using 4.0ghz for my daily usage, i just wanted to see my CPUs capabilities.

 

[MeteorsRaining]

For that matter, it's quite capable.

 

[Ephesius]

Alright tried the 4.5ghz, started with 1.280v, got blue screen after a minute. I think i can stabilize it below 1.3 mark, considering i didn't change anything like bus or cache voltages or anything that is useful for stability. I will make further research if i intend to OC that high, thank you for your help.

As a result i can say that i got a fine processor atleast Some processors can't even get past 4.2 mark and my 4.2 voltage seems quite low from what i heard.

 

[MeteorsRaining]

Indeed, you got a good CPU, if it's a jackpot or not can only be accertained with advanced (or higher) OCing. Research (and Google) shall help you tons. All the best
