Is 1.44v on a 6700k safe for 24/7 use?

[EunSoo]

Hey, so I am considering getting a 6700k from someone but they said that they overclocked it to 4.9ghx on 1.44v which seems awfully high. Should I be considered about the chip dying sooner because of that voltage? It's been like that for "over a year." Thanks

You should be fine, although to keep power down for 24/7 use, I would keep it at stock settings.

That sounds like it would run pretty hot...

Depends on how the previous owner cooled the chip. It's not the voltage itself that damages and kills components, it's the high voltage combined with high temps that does.

So as long as it was kept cool (i.e. under a custom waterloop), it should be fine. I'd ask him that first.

1.44 is to high for 24/7. Try and keep it down to 1.375 at max for 24/7 voltages

that's right on the edge, safe, but i wouldn't do 1.44 for 24/7. I think it'd degrade the chip way more likely than kill it.

 

if it's a good deal, go for it.

i would go for 4.7 @ 1.381

If you use adaptive mode for core voltage and CPU is configured in a way that it is sitting at minimum voltage and clock when idling (you can do that for example with adaptive mode and enabling c-state) then you are generally fine. Then for web browsing and things like that you will be sitting at very low voltages and clocks and OC clock and voltage is only going to kick in when there is any meaningful load, so effectively your average voltage will be probably below 1.0V across a day of typical PC use. Just don't use fixed voltage because then you get this 1.44V 100% of the time instead of like probably less than 20%. 

 

Generally temperatures matter much more than voltage, for games you don't really need to worry about high core voltage. This kind of workload is not hard, CPU is not overly stressed, so temps and power draw are low. Real degradation happens with heavy workloads at high temperatures, or if you run fixed high voltage 100% of the time for no reason. The best way to optimize your overclock for various loads is to configure your own throttling with something like Asus Thermal Control Tool that I use with my 6900K. I have it running at 4.4 GHz 1.375V, with C-states so idle is 1.2 GHz 0.78V so overclock and overvolt is applied only when needed, and with this Asus Tool I have set the CPU to throttle back to 4.2 GHz/1.275V when temperature exceeds 55 C. This way light and heavy workloads are differentiated and proper overclock is applied depending on the load, so the real amount of time when this 1.375V is actually applied is very small. 

 

Its all about optimizing, raw voltage number doesn't mean much.

yeah, I'm not going to use his numbers for my overclock. I'll redo the process

alright, I'll ask him how it was cooled and what his settings were. Thanks guys

That’s very high. It’s perfectly “safe” but it’s not great for the chip. It’s not going to die, but the voltage required for the OC is going to increase over time
