i5 6600k overclocking poorly cant go past 4.3ghz

[an annoying pirate]

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

Dial it back to 4.0GHz or 3.9GHZ....4.3GHz is almost reaching beyond the 6600K's TDP....Stop using voltage to OC.

Should be fine up to 1.4 volts. And potential for 4.8 ghz so long as you can keep it cool

3.9 is litteraly turbo boost aka somewhat base clock please take your bad post somewhere else or comeback once you learn to overclock

yea 1.4 is my max voltage but once i start getting in the 1.36 vcore my cpu start getting toasty at 90C during stress, i know during gaming it doesnt do these kind of temperature but i like when my cpu is under 60C i just dont know if i can get my cpu to even reach 4.4ghz which would be a respectable overclock

Corsair H60 is trash, no better then $30 Cooler Master Hyper 212 EVO aircooler.

Want to overclock better then get beQuiet Dark Rock Pro 4, Noctua NH-D15 or 280mm radiator AIO if they fit in your case.

fine for my cpu cuz my cpu cant even oc more than that unless i go beyond 1.4vcore which is a nope for me
plus i get under 60c during gaming

You said yourself that once you start getting in the 1.36 vcore your CPU is starting to get toasty, the reason it starts getting toasty is that trash like Corsair H60 is not enough to cool it, hence the better cooler.

do i need to point out that is under FFT test which is a heat torture test,
at that voltage i get under 65C in gaming scenario this is still perfectly fine

[MarioTwins]

Could try deliding it too if your into that haha.
I delid my 4790k and it dropped 15 degrees.
That chip turned out to be a terrible overclocker anyways. But runs really really cool at 4.4 haha

Wow Edmund you really should learn to OC as you apparently have no idea what you talking off.

When OCing you always go way beyond the rated TDP...And you not going to go beyond the TDP by the clockrate bit because of the voltage.
You have to change the voltage in order to OC... Otherwise you'll never get a stable OC.

Cant agree more tacoshy

[tacoshy]

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).

I think you have got really unlucky, my old 3570k matches that at lower voltages (also on an h60 since new lol), your right that if your temps are ok, you don't need a better cooler, however, given that it's bsod after a short while, I am curious if your temperatures may be reading wrong, 60c under load with over 1.3v is very cool.

Do you happen to have another cooler to try or can borrow something a bit beefier to test with?

Beyond that, you haven't touched the bclk have you which could be causing the issue to send your whole system out of whack (don't suppose you have, but it's always good to check).

Great advice tacoshy and no i didnt touch anything other than multiplier and vcore voltage. And llc only give me the option. Auto,enable,disable
I have the msi z170a gaming m5 motherboard.
I didnt use any other setting since im still a oc beginner and dont really know what these settings actually do

No i dont have a better cooler and i stopped bsod with higher voltage as said in my original post
Under 60 is during gaming load and avg 65- 70 when playing tf2 uncapped

What PSU do you have? How many Amperes on 12V line?

Please read the first post before posting....
i litteraly listed all my spec there
