Safe voltage?

[Fyre]

I just built a new computer and read up on overclocking and I heard you should not exceed 1.3 volts on the core how true is this statement? My OC I'm running right now is 5.0 ghz at 1.375 volts, but stress load temps are fine I see 80c max in prime95 torture tests. Should I consider lowering voltage and going for a less aggressive clock speed?

Yes you want lower volts for sure, I wouldn't like to have a 24/7 for a devils canyon about 1.25

Try 1.2-1.25V and see what frequency you can achieve

The difference between 4.5 and 5.0 GHz for daily use isn't even noticeable

Agree with the other guys. I wouldn't like to go past 1.250v, though saying that, if 80°C is your max core temp at 1.375v after a prolonged run of Prime95, you must have some outrageous cooling!

Not really just the H100i cranked to max during the test as well as case fans at max.

I did lower my clock speed but just barely. lol I managed 4.8 on 1.25 volts and temps were still good on stress testing so I bumped voltage up to 1.275 and got 4.9 ghz

I also may have not given the max temps when I said 80c, I think that may have just been the temp during the point of prime95 when I did the validation. I actually saw spikes into the mid 90s, but they quickly dropped afterwards.

I'd say 1.25V and 4.8GHz is more than enough for daily

That is amazing cpu 1.275v at 4.9 i wish my cpu was like that

LOL I don't even give my 3970x that much and it's Sandy.

You'll drastically shorten the life of the CPU at that voltage with a die that size dude.

I dropped it back stock and ran a test and on stock turbo mode it ran at 1.25, really 1/10 of a volt is that much? Regardless I am running at stock turbo I was just seeing how much I would get with a little extra voltage.

I read that Intel has shipped some 4790k's with a stock voltage of 1.25

So I'd assume if Intel are shipping these @ 1.25, then they deem it safe enough.

1/10 of a volt is huge. CPUs work in millivolts, that's how tight it is.

I run at 4.33 not 4.6 even with all the cooling i have lol..
Why??
Voltages. I could keep pushing them up and get the speed. i have had it to 4.8 no probs.
But there really is no point to it.
I use offsets and speed step and it takes me quite a long time to get the cpu totally stable at a safe voltage because of the offsets.
BUT the benifits are greater.
Gaming is perfect. the power consumption is lower. the cpu is under less stress. And i have confidence that its not just going to be dead one morning when i wake up.

Indefinite 24/7 stable is the aim of the game.
get the most out of it without killing it slowly, and yes as mentioned 1/10th of a V is a lot when your talking about components so small you can fit millions of them on your fingernail.
