Help over clocking my 6600k ?

[KamilKrait15]

hi. I have tried to oc my cpu,  but all of my over clocks have been unstable. any suggestions on voltage and clock?. I would like anything over 4.3

What voltage have you tested?

1.3

Try 1.35?

1. Don't be crazy with the voltage. Change it in increments of 5 or 6

2. Try to find your processors sweet spot. You want stability and speed. You might not be able to reach 4.3GHz, but you will see an improvement.

3. Fuck around and find the highest frequency that is mostly stable, then once you see instability, raise your voltage slowly. If your voltage starts to get too high, lower the frequency and set back the voltage a little bit.

What cooling do you have?

 

I wouldn't go far above 1.3v on air.

 

If heats not holding you back, your chip might be(not all chips are created equal).

There's a really good guide on pcgamer you can follow. Just go easy on the voltage increments and be patient

more than sufficient cooling ?

5 or 6 volts would melt your CPU

Lol I mean mV or however it's measured. Sorry for confusion.

if you increment by 5mV then you're going to be doing 60 stress tests just to get from 1.0v to 1.3v

I guess that's just me then what increments to you do?

[KamilKrait15]

is aida 64 a good stability test? or should I use a different software?

Most likely 10mV, if you do less you get the lowest possible voltage.

Around 1.35v should be the sweet spot.

for what clock?

[TidaLWaveZ]

Vcore voltage

If you're unsure of anything, you should read a few skylake overclocking guides.

 

It helps a lot to understand everything you're doing.

4.3 Ghz should be fine with around 1.2 Volt.

 

If you need 1.35 Volt for 4.3 Ghz, you have Lost the Die Lottery really bad.

Skylakes ha ve a sweet spot. Like they need xx mV more, for 100 Mhz more.

But at some point, for another 100 Mhz, you dont need the same addition of mV, but a LOT more. For example, at some point you will need a whole 100 mV more for the next 100 Mhz step.

 

You should find the sweet spot of your die, and this is not 1.35 Volt.

It's which voltage you need for which clock speed. 

 

Example:

If you need 1.35V for 4.3 Ghz, but 1.2 V for 4.2 Ghz (extreme example), then 1.2v at 4.2ghz is the best setting you can Run.

You will NEVER EVER notice 100 Mhz difference. Mostly not even measured.

But you will notice 0.15 Volt for sure.

for your max stable in coherence with your specific silicon lottery ticket.

after all of my willingness to overclock I'm finally at this point. but will still push for more. is my chip good?

[Guest]

find the maximum OC you can get with voltage you are comfortable with (in terms of temperature, etc.) and then find the minimum amount of voltage to run that stable.

Oh, its a quite old Bios version date...^^

 

Is that MSI? I would suggest, you get the latest Bios update, since there should have been some stability improvements, and then try out some Overclocking.

The older first bios versions might still be somewhat buggy.

what's the highest voltage I can go before I start to damage something?

first do the bios update like @Darkseth said

then, is not so much about voltage, its more about CPU temps.

more V=more Temps so you need to make sure that under stress the cpu dont reach high temps.

But also this doesnt mean to push your cpu until it hit 90c, you need to find the sweet spot like @Darkseth said.

 

Edit: i think 90c its the point where the cpu will start to thermal throttling
