Overclocking help with 4670k.

[Reddax]

Hello, I've been trying to overclock my 4670k for a while now with my GA-Z87X-UD3H.

But frankly, i've been too scared to. I know i only need to alter the multiplier and vcore but i'm unsure where to start. I'd like to start at around 4.0 multiplier.

My temps are very cool with my hyper 212 evo, keeping stress core temperatures at around 50 degrees Celsius.

Tips on where to start with settings that i would need to change in bios, would be great.

Thanks.

Be prepared to BSOD a lot i did 4 or 5 times with mine, i first started with the multiplier then the base clock and then the volts

It turbos to 3.8ghz on its own, so 4ghz is really modest. I would start from 4.2-4.4 and go from there.

Short version:

Start by setting vcore to 1.25V and multiplier to x44. if that runs stable, icrease multiplier until you become unstable, then reduce to last stable setting. If you are not stable at 1.25V and x44, start increasing voltage (+0.01V steps) until your temperatures exceed what you are comfortable with (they shouldn't go beyond 80-85°C under load, ideally), if still not stable start reducing multiplier. I don't recommend going above 1.32V for x44, especially not if you're air cooling. Stress test for a few hours between every step, to determine whether your system is stable or not (I recommend using IETU for stress testing). For more detailed instructions as well as info on ring bus stability, haswell power saving features and memory overclocking, google "haswell overclocking guide" and pick one of the detailed guides there.

the way i do it, just set the voltage to the max you are comfortable with temperature and power consumption wise, keep increasing clockspeed in 0.1 Ghz steps until it becomes unstable, when it becomes unstable go one notch back then start reducing the the voltage until it becomes unstable, then put the voltage one notch back and run that long stability test.

 

i wouldn't start out with a 4,4 ghz overclock or something along those lines that the others are suggesting, that might easily give you bsods, you don't know how your chip is going to act, just do it step by step and run stability test for 15 minutes or something like that until you get to the final stability test that should be abit longer.

I've been trying to install IETU, but it just gets stuck on the splash screen and freezes. But i'll give this a go later on when i've got some spare time.

This is also a good guide, aimed at LGA1155 but everything still applies on LGA1150.

Same mobo. Follow the TTL guide on how to setup Load Line Calibration. I have it on extreme. You can jump few multiplier increases on first try. From 34 to maybe 37-39. That should run without increasing volts or with tiny increases. It also is counted as overclock and gives you confidence.
