4790k Overclocking Lifespan question.

[saturdayeveningpost]

Hello. I had recently allowed my Ai tuning/tweaker in Bios to automatically overclock my 4790k to 4.6ghz at 1.35 core voltage. I am using a cryorig ultimate for cooling and it stays usually well under 60c when gaming.

 

It was extremely stable and cool, but reading  online about safe voltages of 1.3 and under for haswell made me weary, and have since backed it down to 1.25 v at 4.4ghz(default, I believe).

 

My question is,  giving it was running so cool at 45-60c on average, would the 1.35 voltages truly limit my cpu lifespan down to 3-4 years? I have seen some people say yes, and some say no if your cooler is adequate. 

 

Thank you for your input!

Increasing the operating voltage of a part doesn't decrease its lifespan. Higher voltage will cause higher heat output and if the part is allowed to run at elevated average temperatures, that will decrease its lifespan. As long as the processor is within operating temperatures, it will likely long be obsolete for your primary uses before it croaks.

you should be fine for a few years at that OC and then one or two after that one fails at stock, maybe more. depends on the history of the chip and the silicon lottery among other things. I got mine to 4.8Ghz at 1.335V and 5GHz at 1.375V. 5.1GHz needs 1.42V tho so i only run that for benchmarks

I have more problems with people using auto overclock than running higher voltage. Auto overclocking always overshoot voltage (i.e. give more volts than needed).

 

As for max voltage for Haswell, you can push 1.4v to it without degrading it so fast that you notice it before it's no good for heavy gaming. The problem with Haswell is the FIVR, fully integrated voltage regulator which converts VCCIN (1.8V stock, sometimes go higher when overclocking) into other voltages the CPU uses (core voltage, system agent voltage and I/O voltage), and that thing (Haswell refresh do better than Haswell here) can get really hot. That's what limits the core voltage.

Thank you for the replies, I will continue at 4.6 for the time begin. 

 

@Jurrunio i would like to get off auto, but for the life of me, I cannot find the 'multiplier'. So I have had to let it for now.

Asus calls it "Core Ratio"

if you decide to go manual with the overclock, make sure to put VCCIN or CPU voltage(the one thats not core!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!) to 2V for some extra juice and MHz  Diffrent motherboards call it diffrent things, core ratio, multiplier or anything similar. should be a number that says 40 or so

Thank you both, I was able to adjust it, but failed the overclocking when typing a multiplier even lower than what it did automatically at 46....I am obviously far too much of a tech noob to do it manually. So, I resign and am now back to 4400mhz(default) after letting it auto tune like 12 times with a different result each time.
