About i5 4670k overclocking

right, that is what I figured it wouldn't go up much , I would just leave it as that and just check HWmonitor for any high voltages a few days of running .
I don't think you will have any issues at 4.0 .

ok thanks, so leave it as auto mode? because i saw many people running them with adaptive mode with auto inside it

I really don't know, would have to read the manual on that .
I thought if you pick adaptive to really use it you then need to pick a value to be added or subtracted .

Now, for my system and I have a dog chip in my opinion, I need 1.15 for 4.0 stable. I also run 1.24 for 4.2 stable operation. I'm at 1.38 for 4.4, unsure of stability as I won't run the system that long at that voltage as it's past my comfort zone.

The one thing we have learned about hasewell is that the chips are all over the place with regards to stable operation and voltage.

What's the redline for voltage when it comes to Haswell? 1.3? Lower?

Thanks.

wow, yours is even worse than mine :/

haswell OC guide

my chip runs 4.0 at 1.050 (stock), w/o adaptive. adaptive is bad, mmk ?

anyway, my suggestion is: overclock the cpu. if it goes fast, say 4.4 with 1.20, then ok, otherwise keep it at stock... i mean 3.4 + turbo. the results are the same.

I need to ask some question before i start to oc my cpu. What is the stable voltage for i5 4670k at 4.0ghz? And which mode should I use for voltage setting in asus mobo, adaptive or manual mode? Any other settings have to change to make it stable?

Turbo speed on that chip is 3.8GHz, so you're guaranteed to be able to run 3.8GHz at stock voltage. 4.0GHz is just a 5% overclock, so most likely it'll work at stock as well.

I don't think you will have any issues at 4.0 .

With my Sandy Bridge, I think the line between "Auto" settings and tweaks to offset or turbo "extra" is between 4.2 and 4.3. It might be the same or a tad lower for the IB-K's and Haswell chips. But you'd really think that you'd be able to reach 4.0 on the default, auto voltage settings.

 

[NirHahs]

Does any other setting that can improve the voltage to get lower? Example if my voltage is already stable at 1.15 for 4.2ghz and cant get any lower than 1.15, does any of other setting such as PLL, CPU strap, CPU load line cabliration, CPU voltage fequency (all of these just an example)?

please refer to the guide i have posted above. its what the vast majority of us use here, and it contains the answers to every one of your questions.

haswell OC is nowhere near as easy as 775 was. read it and it will clarify many things (or confuse you, either one)

That guide is for gigabyte mobo. I know it doesnt different much, but it will make me confuse as a new overclocker.

Yes, well each chip is different as to what core voltage is needed but for example my 3570k is running on auto with 4.2ghz . That is with voltage running around 1.112 under load (prime95) .
Now 4.2 is sweet spot going up from there needs more voltage so I just leave it here and I have no need to adjust it higher or raise things like LLC .
Which is small increase over stock which was around 1.080 ,stock clocks .

If your going for higher OC, don't use auto especially once you adjust LLC . It will go higher most likely, offset or manual voltage would be best .

It should run @ 4Ghz without voltage touching.


If you want 4.2 then you have to play with the vcore in your bios. gl

the difference, if any, will be what the maker of your mobo calls some voltages. i can't tell you for sure, but i imagine they will have the same naming standards ... i have a MSI and i used the same guide.

anyway, the point is, the guide explains overclocking on a haswell. if you had read it you would know the answer to your question.
