2500k simply does not die/degrade.. even after almost a decade at ~1.5v and almost 100°C

[K0NG]

So my friends brother was 11 years old when he got his i5 2500k back in mid - late 2011.

his dad or my friend went to the bios and put the multiplier to 49 and pressed F10 back when the PC was brand new.

Now he replaced his Old 2500k and gave the CPU/Mobo/Ram to me. (he played games on a daily basis for almost a decade with the original intel Stock Cooler.)

The 2500k runs at 1.48 - 1.5v under load at around 90-95°C with the stock cooler in games like Overwatch and peaks at a hundred in RB6 Siege.

and the chip did not degraded a bit, is primestable and does everything perfectly fine.. beside almost boiling itself.

the Mainboard was replaced 3 years ago ( a generic Asus one.. did not looked further)

Now i ask myself why people are so anxious about overclocking and degradation...

Yup, I can also confirm my 3570K still works as the day I got 7 years ago and I am running 1.44v through it and temps are peaking at 100c.

smaller nodes are more sensitive to voltage tho

 

and tbh not using LLC helps with the lifespan too

A sample size of one doesn't represent the millions of other chips.

 

This is on top of the fact we don't even know what the expected life span of a given part is when running under the specified conditions. All we know is subjecting it to higher heat for long periods of time degrades it faster.

That's pretty sick. Meanwhile my 4790k started noticeably degrading from the miniscule 4.4 GHz OC I was able to achieve with only a year on it. I'm pretty sure I got the worst binned 4790k around. Still a great CPU at basically stock speeds though.

well all of my own CPUs behave exactly the same.
i overclocked them all to the absolute max. (well above 1.4v and beyond)
my old FX6300 was at 4.9 Ghz at over 1.5v for almost 4 years
my 4690k is still in a second PC at my parents house which is at i think 1.45v
my 8600k at 5.1 Ghz 1.44v (sold it to a friend where it is still in use at that clock/voltage)
my 8086k was 12 months at 5.3 Ghz at 1.45v

and now my terrible new 9900k at 1.425v at 5 GHz.

none of these chips degraded over time.

if the average chip would degrade so much or even die at 1.52v intel would not give a 3 year warranty.. (since you can not tell if a CPU was overclocked or not.)

And Electromigration does not magically stop in a single piece of silicon.

Well as far as I know there aren't any definitive studies of how long it actually takes a CPU to degrade and/or fail if run at high voltage, all we really know for sure is that they do eventually.  However, eventually could actually be 20+ years.  Also I am not sure if we even know how much degradation might be occurring, prehaps it immediately starts to degrade at those volts but the degradation is only .01% in performance per year meaning that after 10 years you would lose 1% total performance.

 

This honestly doesn't surprise me though because I am sure chip manufactures want to create situations where A) you don't abuse the hell out of a chip to the point it fails while within the warranty period and B) you become concerned that your chip is old and might fail any day thus prompting you to buy a new chip.  It wouldn't make sense for them to release information that you could theoretically bump the chip up to 1.5 volts and have a MTBF be 150,000 hours (17 years),  Instead of 250,000 hours (28.5 years) at 1.35 volts.  Instead they just say you shorten the lifespan and let us infer that the chip could fail at any time if we ran it at 1.5 volts constantly.

Not sure if that’s really a problem , you should be happy that it last that long (and probably will last for quite some time as well)

i5-2500k is a seriously good value on the used market. You can buy a mobo, memory, cpu, and overclock the hell out of it for $150 or less on placed like eBay. Even if you fry it running at 1.5v for a year, that's only $35 for a replacement
