4670k First time overclocking - need help!

[Lexxor]

Specs: Mobo - GA-Z87X-UD4H
CPU - I5 - 4670K
Case - Corsair 300r Carbide
Cooling - Kraken X40 (single 140mm)
GPU - MSI 770 TF Gaming
RAM - G.SKILL Ripjaws X Series 8GB (2 x 4GB)
PSU - SeaSonic M12II 850

-----This is my first time overclocking-----

So ive been trying many different configurations with my 4670k to get the most out of my system. I tried running the cpu at 4.5ghz but even after cranking the VCore up to 1.300 it was still unstable and wouldnt run Prime95 for more than 30seconds.
Ive settled for 4.2ghz and am currently running the VCore value at 1.25 to check for stability. So far all the voltages havent lasted more than a few hours in Prime95 at the most intensive stress test.

Im running CPU-Z, CPUID Hardware Monitor and Prime95

My CPU temps never really rise above 73c

My questions; What VCore value is still relatively safe for this 4th gen high heat haswell cpu? (i read 1.19....but im way past that...lol)
What other settings should i be tweaking in the bios (possibly something im missing all together?)
Any other tips or suggestions that can be provided to achieve 4.2ghz...or even higher, preferably

Thank you buzz. Op try my guide and post any questions you might have

 

[Lexxor]

Ok i believe i found a stable overclock within my comfort zone.

Running my 4670k at 4.3ghz with Voltage set at 1.368
I didnt want anything higher than 1.4v and i had to do just that to achieve 4.4ghz so i settled for 4.3
Core temps remain under 58c on the highest core when im playing games and dont go above 87c under full Prime95 load with the Kraken x40

Sry for taking so long to get back, i have crazy work hours

 

[Lexxor]

Ok so i blue screen after about 1.5 hours with Prime95 with these settings but ive been using this config for a week or so and everything seems to work flawlessly.

 

[Buzz247]

use and load testing are very different situations. Load testing is designed to make sure you are stable under any condition. So, it may work on normal use, but if you run certain programs it will fail if not load teasted and set to be stable.

Go back in, back down clock, up volt, down volts, whatever you need until stable on load to ensure stable conditions for any program

 

[Lexxor]

What do u mean by up volt but down volts. What's the difference? And am I really supposed to change one setting by .001 increments and just sit for hours to c if it blue screens or not? Seems like there's gotta b a better way...

 

[Buzz247]

yes - you make adjustment, and run prime 95 to see if stable. That is the BEST way. By "better" way I assume you mean faster. OC is not a race, it is an endurance run of patience. You can haphazardly do it other ways, but... well... you experienced what happens then. It takes time. Do it right, never have to again.

Incidentally, what are you current settings? temps under load in stress test?

 

[Lexxor]

Which settings are u looking for exactly. I have the core clock set to 4.3ghz with the Vcore set to 1.36v. I dont really know what else to change, cant find any good guides for the gigabyte ud4h mobo.
At these settings it works pretty well, havent had a single crash in a week. If i run Prime95 it blue screens after about an hour and half. When i originally used these settings the temp only spiked a few times to about 87c but when i ran it earlier today with the same settings it spiked to damn near 97c. Crazy.
I dont do any super intensive processing, mostly just gaming here and there. I run HWmonitor frequently and the temps after a regular day r never higher than 58c.

I have the same mobo, so I'm going to see if I can help you out.

1. Set "All Core" CPU Multiplier to 44X: Performance tab > Frequency tab > CPU core clock
2. Set CPU cache Multiplier also called the Ring bus multiplier to 35: Performance > Features > Advanced Core Features button > Uncore ratio controls this (as I understand it).
3. Set Fixed CPU Vcore to 1.25 -1.30v: Perfornace > Voltauge > CPU Voltage button > CPU VCore
4. Set CPU Cache Voltage also could be called Ring Bus voltage to 1.20v -1.25vv: Performance > Voltage > CPU Voltage > CPU Ring bus voltage
5. Set Vrin also called "CPU Input Voltage" To 1.9v - 2.1v: Performance > Voltage> CPU Voltage > CPU VRIN

The names of those buttons may not be right but hopefully that is enough to get you there at less voltage then you are using now... mine cannot run that high, it gets too hot, but I'm only at 1.239 V for 4.4 GHz. Thanks for your guide Intel God. Should I normally be getting high temps (85+ under 100% load) at ~1.3V because I have just the 212+?

First off, thank you for ur time Jake i appreciate the help. Unfortunate ive tried different things and have most certainly looked over a few overclocking guides as well as the one from Intel God i assure u. Nothing seems to work for me, i think i just received a bogus chip my friend. I used the settings u tried, which i have tried b4 except for the Input Voltage, and i crashed very soon after the Gigabyte logo disappeared.
I have the intel protection plan on my cpu so im just hoping that it'll blow out soon so that they'll replace it lol.
My current settings are 4.5ghz with a 1.48Vcore value. Dont know how long this will enable the cpu to last, if it doesnt blow soon maybe ill just keep going on the voltage. I just dont want to damage any of the other components. I dont seem to be getting anything higher than 90c at full load after a few hours, esspecially now that its Sept and the ambients are decreasing the Kraken seems to be doing a decent job

 

[JakeWJF]

Oh, I know those are just the four steps copy-pasted from Intel God's guide and you've read that already, but I thought you were having trouble finding them all in the bios. Sorry about your chip. I'm curious what voltage it will take to burn it out with such good cooling.
