i5 6600k overclocking poorly cant go past 4.3ghz
idk if i lost the sillicon lottery very badly
but going 4.3 ghz is unstable had to set it to 4.2ghz @ 1.33 vcore for a stable overclock
tryed 4.3ghz at 1.30vcore (at first i though ez overclock right?) bsod 30 seconds after launching window
tryed 4.3 at 1.32 bsod upon launching prime95
tryed 4.3 at 1.35vcore core1 stop at +/- 3 minute under prime95 blendtest
didnt went further due to rising temp

previous overclock was 4.1ghz stable @ 1.27vcore

system spec:
CPU: i5 6600k + corsair h60 aio
RAM:16gb 2400mhz 2x8
GPU: sli 1070 aero oc
OS DRIVE: ssd samsun evo 850 1tb
PSU: evga supernova g2 750w 80+gold

i wonder if this is silicon lottery or just me doing it wrong
(edit: more info added)

Well to get a useful piece of advice. With the settings you using now I believe a 4.6-4.7GHz OC is realistic and possible. Maybe even more.

First things to mention is that I have to agree that your cooling solution is way below what should be taken and a Prime 95 Test will go way beyond what you see in "light" CPU usage as gaming.

You way not close to the end of OCing your CPU. You can safely bump up the voltage to 1.4V (with a good motherboard it would even be safe higher). That should already shoot you to 4.4-4.5GHz. All you need is a good cooling solution to get tempreture under control as your TDP will skyrocket and the TDP of your cooler will be insufficient.

Then you also should provide enough stable power by changing under power settings the load-line calibration to extreme. Next disable Turbo Boost and all C-states. For gigabyte motherboards also disable VT-d.


If you want to OC higher you also need to adjust the Uncore which should be around 400MHz below the CPU clockrate. Also If OCing higher you need to add an AVX Offset from 1-5 (the higher the more stability).

Hmmm..
i guess results vary from time to time and board to board then.

Ive used the auto OC on my ASUS Z68 V Pro Gen 3 board for the past 5 or 6 years for a 4.3GHZ overclock and had absolutely no issues.

But as a natural rule, some boards do overclock better than others.

I have the highest end Z270. One Asus board comes on par to it tho.

Even when auto OC as it is a pre-set works it still doesn't mean it is optimal. A good OCler would get better settings for less voltage and heat or little higher clocks out of it.

@OP

Do you have Intel Speedstep enabled by any chance?

Major overclockers are "Said" to disable it when overclocking, but i personally prefer to allow the CPU to downclock when the power isnt needed.

Yeah i guess Taco, some people arent extremely picky about their overclocks though lol.
