4ghz OC...Safe?

[Conure]

Hey guys,

 

I've recently got my CPU to 4ghz on a new watercooling kit. I was amazed as the whole thing was easy...The Corsair H60 went on in minutes with no issue, and the OC was a very short guide followed by the PC booting and 24 hours prime95 with no problems.

 

Anyway, it's an i5 760 2.8ghz @ 4ghz...Voltage is 1.35...I'll probably replace my CPU in a year or so, but (for my peace of mind) it should last that long right? Bearing in mind it never goes above 65oC and that's with Prime after 24 hours...

 

Thanks, hope you can stop my worries!

I've had my e8400 at 4.0 with a 50 dollar after market fan with no issues. I think it depends on whether the cpu oc's well. At those temps after 24 hours, you're good imho, especially given the low voltage.

[EtherealN]

With those temps and that voltage you should be fine. It might be worth checking some motherboard temperatures as well though - google and download HWmonitor (same people as made CPU-Z) and you should be able to monitor all temperature sensors on the computer - just in case there's something being unfriendly on your mobo.

 

But generally speaking, 4GHz shouldn't be a worry.

[Conure]

Thanks EtherealN :)

 

Checked that one and the max my mobo hit after some use on prime was 57oC! That was the northbridge.

[EtherealN]

Does indeed sound really good then. :)

 

Something you can do is leave that thing in the background for a day while you do your stuff, whatever it is, and check it before the end of the day - then you can see the all-time-high for every component. If nothing spikes at that point, you're probably golden. :)

[Conure]

I would + rep you all but I can't! Apparently I need to "spread it around".

 

Cheers :)

Hey guys, sorry to double post - just checked speedfan and get an "Aux" reading of +0.25V which is flagged up as red. Presume this is a misread/unimportant but nevertheless thought I'd ask :)

I run my I7-920 @ 4GHz from the day one.

How long have you had it for out of interest. The reason I ask is because although I often hear that OCing shortens the lifespan of components, I don't think I've ever heard of anybody losing a chip through an OC. I guess that;s because most of us upgrade our CPUs before there is a chance for it to break!

I've got the system running this way for less then two years. I wrote about the whole setup and FC testing, but it is in Serbian language:

I have Intel dual core E6400. oc to 3,4 GHZ with h50 corsair water cooler.. I also added one ordinary 120mm fan placed vertically on my Ati HD 6790 card that is blowing on my northbridge chipset and memory modules...So now my northbridge shows 36 celzius on speedfan utility..

[hassata]

With a tiny bit of luck and in all likelihood, one would upgrade long before the processor lifespan, even if degraded because of an over-clock.

[EtherealN]

Yeah. Overclocks do, probably, reduce lifespan of the component, but I've never seen any numbers indicating that this is a practical component or even statistically significant compared to "normal" hardware failures.

 

The "normal" lifespan of an IC isn't exactly short anyhow, so shorting it even with 20+% would probably still see it feeling rediculously stone-age before you run into problems. That is, as long as all power cirquitry works as it should (never... ever... skimp... on... PSU..).

Well, one of the most active research fields in microelectronics currently is how to exactly control the life span. If you look at how some mobile phone brands always die exactly after the warranty voids or the next gen is available, it seems they are already quite successful with it. :)

[EtherealN]

Yeah, but those are uniform units that they can work on. With PC's it becomes so chaotic that you can't really get the same clean test environment - or rather, as soon as you make yourself a clean test enviorment, the applicability of the results to actual consumer PC's starts becoming suspect. (For example, I'd expect the risks of early degradation involved would vary greatly depending on mobo design - especially the power rails - and power supply.)

 

Also, of course, individual IC's will have different MTBFs, but for a whole unit it becomes easier to predict since you are dealing with a larger amount of components. Law of averages etcetera.
