4-Way optimizaion & 4770k

[Villani]

Hello,

I OCd my 4770k with the new software to 4.4GHz, but apparently my mobo doesn't support the automatic OC feature, so it only has the 3 presets to choose from to OC the CPU and I took the 4.4GHz one. Now my CPU runs at 1.264V and idles at 26-29c and it hasn't crashed once.

So, would this OC be safe considering the voltage? Can I just leave it as it is if it's stable?

Hi Villani 🙂

That sounds fine to me...just one thing, the idle temp doesn't mean much..it is the temperature and voltage at load running a stress test or a demanding game that are more interesting. If you are under 75 or 80 degrees running a stress test then all good...

Alright, a small update...

I increased my voltage to 1.270, kept the clock at 4,4GHz (tried 4.6 @ 1.310V but it crashed). I also enabled XMP.
I ran RealBench1.1 and my temps were 72'C at max on full load.

I tried to get 4,5GHz on the same 1.270 but it crashed, also on 1.280.

Is there a notifiable increase in performance if I increase the clocks to 4,5 from 4,4GHz?

Hmm...

Now my PC keeps crashing while playing Osu! with 4.4GHz @ 1.270V, raised to 1.280 to see if it happens again.

Might be either the CPU or memory thats unstable. Be systematic; get the CPU cores stable, then work on the memory side. Sometimes, a CPU can need more Vcore (apart from the obvious VCCSA or Cache or DRAM voltage adjustments) when running the memory at high frequency.

[Villani]

Yeah...
I disabled XMP, gonna leave it disabled, don't feel the need for it in gaming/ everyday use.

Had to raise voltage to 1.30V, ran a stress test for an hour, seems to be stable now at 4.4GHz.

I know it's a silly question to ask, but if I overclock 4670k to something like 4.2 GHz, how much life time (approximately) will I be taking of the cpu?

[Villani]

And my computer still keeps crashing occasionally at 4.4GHz with 1.30V, even thought it passed almost an hour of stress testing.

WTF?

[Raja]

Might be a below average CPU. There are samples out there that don't clock to 4.3GHz with anything less than 1.40V. Reduce the CPU clock more until its stable and work from there.

[Villani]

Increased the voltage to 1.31V. Hope it stays stable.
