Safe vcore on 2500k?

post #1 of 8
Thread Starter 
So I was talking to my friend, and he was telling me that voltage higher than 1.36 or so on i5 2500k will degrade the life of the chip and wear it out faster. Is this true? and if so how much really does it degrade the life of the chip?

Look at the Sandy Stable thread. There are people running their 2500k's at 5.0GHz 1.5v 24/7 and it runs fine.

I personally wouldn't go over 1.45 unless you are water cooling. Maybe someone else should answer this though, I have only had my 2500k for 4 days.

Nobody knows an exact number. But more voltage is going to degrade more. I personally feel that 1.35v is a safe acceptable limit and is my personal limit, for now. My current 24/7 clock is 4.5GHz@1.32v.

1.45V for air, 1.5V for water.
My personal preference is 1.4V max for daily use 1.55V for suicide runs.
Keep temps under 85 while stress testing and you will be alright.

Vcore of 1.45 and under with a load of 82c and under is acceptable. By the looks of your sig rig and your settings you'll sell your chip long before it's life is over. At stock vcore your chip will have far better than 10 years. A vcore of 1.45 7/8 years.

Intel claims the "limit" is 1.52v, but people have done more than that briefly. Personally I don't want to put 1.5v into my chip unless I'm shooting for 5.5+ghz

Take it as you will, this is my opinion:



****Max Safe Voltage and Temps****


Before I go into this, I just want to say that this is my OWN opinion and take it as you will.

No one is absolutely certain of what the safe vcore is for the sandybridge chips. What I can tell you is that many say the max safe vcore for these chips are 1.3 region, however, intel states that the max 'VID' is 1.52 and many say that around 1.4 if your on air and 1.45 should be the max if your running water cooling. Personally I will not go above 1.5v for 24/7 with these chip but that is totally upto you. The main thing to understand is that 'YOU' have to come up with the conclusion of what the max is. That way no one is blamed if the chip degrades (none reported so far, even with so called 'high 1.4+ vcore')

Those that have killed or degraded their cpu's have done so through either by their own fault, running sucide runs with crazy voltages and by not having substantial cooling for their overclocks and voltage or for reasons like their mobo or PSU causing shorting and also BIOS bugs.

Please remember that not all chips are the same, some can do high overclocks with low voltage some cannot.

Regarding temps, CPU throttles at 95c, some say keeping it below 85c is good, some say keeping it below 80 is better, other's say below 75c is really good and there are quite a few that say 70c should be the max. Which ever one your comfortable with and if you have substantial cooling, YOU DECIDE YOUR MAX, just remember it throttles at 95c. If for example you hit 85c in stress testing then in everday usage it shouldn't be higher than 75c which I think is fine, I personally like to keep mine below 70/75c during general everyday usage

keep it under 1.4 and u'll be good for good for years to come.
Chances are you'll prob upgrade before your chip goes bye bye.
