Overclocking i7-4790K

[avsquare]

I think my room doesn't get much ventilation or what

4.6GHz @ 1.202V

Most of the time hovering between 75-78c

Still got thermal headroom to go anot sia

Seems normal, fixed voltage or adaptive?

Ok to me le. Mine aio water-cooled also same

Fixed voltage.

Is there a setting that the CPU will down clock itself when nothing to do? I know got one but forgot which one, like it will go down to 1+GHz when nothing to do.

Now it perm clock at 4.6GHz

Still thinking want to go for 4.7/4.8 or not.

Prob going to test gaming at 4.6GHz and see gaming temps first.

4.6 @ 1.2 very hiong liao I thought?!

i think its better not to waste precious gaming time in squeezing that 100-200mhz out of ur system. i doubt u are going to see any huge differences in fps for gaming. 4.2/4.5 should be more than enough for any game in the market liao

Testing how good this chip is

4.8 under 1.3 then we can praise it abit

ohh not really for gaming but actually to see how good this chip is.

you know, silicon lottery

Set it to adaptive bah.

 

[monikernemo]

But not much head room also leh haha. Turbo already 4.4. Machiam natural only

Keep it below 1.2, anyway once u set adaptive ur load vcore would +.05 lol.
Set EIST, C1E and C3/C6 for power saving.

Hmm later I try.

Did you try to push yours to see how far it can go?

Wow how many box they open to test sia

mine @ 4.4 via bios...

Don't use the overclock program in bios. 1.288 vcore is damn high. Try to set at 1.18 or lower for 44 multi. One bad thing about auto OC is that they supply more volts than normal, giving u higher temps and degrade your chip faster.

Yup, even the auto turbo boost to 4.4 is using 1.212V which is bu11shit

I want to see if my chip can beat this one at siliconlottery

4.8GHz run

 

[hysteriakx]

what stress test u using? i can get 4.7 @ 1.2V on noctua nh l12
did u change the uncore ratio too?

can set offset voltage instead of fixed volt. i heard adaptive might give more than 1.3V during synthetic stress test and hurt the chip?

That is why dont bench at adaptive, only fixed. Once you found your sweet spot then you set the power savings options and do the offset at - 0.03.

Prime95 ver26.6 small FFT.

Yeah adaptive would give higher voltage so I used manual.

uncore fixed at 100MHz didn't change.

The thing is for this chip the jump to 4.8GHz kinda requires quite a jump in voltage, and researched online that a lot of people are almost requiring near 1.3v to hit that clock speed stable.

offset -0.03 for the power saving or vcore?
my stock VID is 1.1 so i set vcore offset to + 0.1V correct? but in hwmonitor i see the VID staying at 1.2 throughout
