How much will 1.3v degrade an i7 2600K?

[Davste]

If I run an i7 at LLC 2 and 1.3v @ 4.5GHz, how much will it degrade it?
Do you think it would last me another 3 years or so?

Also, what are the advantages of overclocking this CPU in general? How much of a difference in gaming would I see between 3.8 and 4.5 GHz? I have a GTX 680.

high speeds are good for minimum framerates, check out this arma 2 benchmark
http://www.bit-tech.net/hardware/2012/04/23/intel-core-i7-3770k-review/7

Minimum framerates:

X6 1100T (stock) 59 FPS
i7-920 (stock) -- 61 FPS
FX8150 (4.8ghz)- 70 FPS
i7-990X (stock) - 81 FPS
i7-2500k (stock)- 86 FPS
i7-2600k (stock)- 92 FPS
i7-3960X (stock)- 96 FPS
i7-3770k (stock)- 100 FPS
i7-3770K (4.8ghz) 106 FPS
i7-3570K (5.0ghz) 106 FPS
i7-2600K (5.0ghz) 108 FPS

1.3 v will last you more than 3 yeara

Possibly and probably. I had an i7 920 running at 1.35 V @ 4.0 Ghz for nearly 3 years and it degraded somewhat in the last 6 months so that it would no longer stay stable above 3.8 Ghz at the same voltage. I cooled it with a custom water loop.

There is a decent chance the 2600k will last you 3 years without any degradation at 1.3V @ 4.5. But if you are relying on it surviving 3 years with overclocking you could get in trouble.

been running 1.47+ for almost a year with my 2600k and its seen over 1.6 volts and still clocks just fine!

dont forget motherboards take a beating and your stability after 3 years could be the vrms and caps on your board.

I also keep the voltage at 1.4+ even at 1600 mhz idle.Its load that will kill your cpu and enless you run intel burn test for 3 years straight dont worry about your chip degrading.1.3 volts is nothing and Im pretty sure even at stock full load the cpu will call for that voltage anyways

SB motherboard all have the offset feature as well, not sure if the x58's had that, mine didnt. So his chip will run at 0.9-1.0v when idle so it shouldnt degrade for a very long time.

well the answer to your question depends on several factor. where you live, temperature+humidity of your room, what type of case you got, which cpu cooler you are using etc. but 1.3v probably is ok provided you got good cooling and you are not living a place w/ harsh environmental conditions.

It'll last 3 years instead of 4

I'd say it should be enough for more than three years before you need to up the voltage again or lower the overclock. Most SB chips will do an absolute max of 4.7-4.8GHz and a few will do 5GHz, but only at 1.4V or slightly higher. When it comes to Nehalem, the initial CPU (i7-920) maxed out in most cases at 4GHz/1.35-1.4V, but the 930/950 could do 4.2GHz at the same voltage.

1.4V is about the absolute max for SB if you want to run without having to lower your overclock/raise voltage in ~two years, and 0.1V under that should mean that you'll be able to sail through for more than three years, also taking into account the lower relative temperature of running lower voltage. Running at that voltage and frequency ensures you have higher power efficiency than running at the stock 3.4GHz as well.

IIRC, with X58 you also had the option for Offset so at idle the CPU runs at a much lower voltage with lower clock speed. It should be something under 1.0V: my 2600K for example idles at 0.97V.

What programs were you running on it? My 920 was at 1.4v 3.9 Ghz for 3 years and it ran at that speed at idle as well and was air cooled. It never had any degradation but I only gamed on it 30 hours a week or so and it was on 16 hours a day.

You pretty much answered your own question. You didn't fully exploit the processor's processor power, therefore you didn't degrade it as much.

If you did frequent video encoding or worked with content creation you would've definitely had to up the voltage again.

Keep in mind that unless you are loading the processor quite often it will be throttling down to a lower voltage/frequency for probably 90% of the time. So 24/7 overclocks these days with turbo boost ain't as hard on the CPU as in the "old days."

 

[SickBeast]

Isn't 1.3v stock volts? If so, it should last 5+ years IMO.

 

[Kevmanw430]

Long story short, 1.3v is nothing. I consider 1.38v to be the highest safe voltage where you won't face degradation. Don't worry at all at that voltage.

 

[Davste]

Thanks guys. It's going to be 4.5Ghz for the next 3 years or so then

 

[aaksheytalwar]

1.3 will only be under load, even if you use it for several hours every day, under load (not idle , that is) you should get at least 2-3 years life with the same clocks and another 1+ years with slightly lower clocks/higher volts. Unless you plan to use for 4-5+ years, no need to worry. Only worry if it will be used intensively without being changed for about 5 years or more,

Depends on how you look at it really.

Using my 2550k for example if I set my muliplier to 47x and use offset voltage of -0.004v at idle and +0.004v of additional turbo voltage my chips at 1.344v-1.360v's under load. The VID shows 1.3711-1.4011v's so I'd somewhat consider it as being slightly undervolted. Others would say that it's overvolted and running out of spec. With the K chips the stock voltage is based on the multiplier being used. The VID is hard coded into the chip by intel we can only add or subtract voltage to or from it. The way I look at is if the VID could fry the chip then it wouldn't be set so high in the first place. I'd think intel would be smart enough to limit the VID to the absolute max while adding a little bit of a buffer zone....But purchased the insurance plan just in case.

 

[aaksheytalwar]

Stock is 1.2 or so
