6700k Maximum Voltage

[Carclis]

I've been playing around with my 6700k and seeing how far I can push it. I have it cooled via a 360 and 240 radiator in a custom loop with a stable 4.6Ghz at 1.36V.

At it's peak the vcore hits 1.373V according to CPU-Z, but at 64C I seem to have further room to overclock. How far should I go voltage-wise before it becomes unsafe for 24/7? Keep in mind the stock voltage for my 6700k was the same as it is now.

I'd say if you feel comfortable with the temps and it's already stable, push further...

for a 24/7 pc high overclocking isnt that good of an idea because over time it may ruin your cpu

If it doesn't get too hot and runs stable I don't see how it could be ruined.

if you want, you can push to 70 degrees but any higher or if its unstable then there is a high chance of cpu damage

but it has been proven that cpu's on steady oc have a shorter lifespan than non OC cpu's

can't you go to a higher clockspeed? i have the older 4790k and im running it at 1.275 volts and 4.6ghz speed. isn't the 6700k supposed to be more efficient?

Different architecture. Can't compare like that.

but isn't it supposed to use less voltage overall? (the 6700k)

It is more power efficient, yes. But it also has many more transistors.

ok nevermind forget i asked

No, Skylake has higher voltage tolerances, and usually requires more voltage.

It's a completely different architecture, the two cannot be compared properly.

There's a thing called warranty, if he does any harm to it that is actually serious, intel has no problem accepting RMA for it.

By the time he actually messed it up from overvoltage and overclocking, it'd probably be time to replace it anyways.

With proper cooling you're good for 1.4-1.45v 24/7 provided it's staying under insane 80c+ temps.  I'd say hover right around 1.4v, it'll be your sweet spot.

I know my 6700k is not a very good overclocker so I'm pretty sure I'd have to go around 1.42-1.43V to get a stable 4.7Ghz. As long as I get 3-4 years out of it that's good enough for me.

its not temperatures that degrade the part over time tho.

 

theoretically, overvolting your chip decreases lifespan, the question is what *is* the lifespan of a piece of silicon?

yep that was kind of what i was trying to say (not really)

well the lifespan of silicon......ummm 20-30 years but it would be only like 3-5 years before it gets outdated

Temperatures accelerate electromigration, which is the cause of CPU degradation.  The hotter the temps the faster this process happens.  The colder the temp, the slower it happens.

well, theres non-overclocked chips that just hit the dust after 5 years, theres chips that easily make it past the 10 year mark still going strong while being in a furnace dust clogged pc.

[Carclis]

Well, it looks like 4.7Ghz isn't possible anyways. Even at 1.44V I get errors/crashes during realbench. Silicon lottery didn't treat me well this time

Lifespan i guess is whether the silicon atoms inthe transistor do not thermally mix.
