Core i5-2500K 4.7GHz OC VCore Question!!

I have a very stable overclock on my Intel Sandy Bridge Core i5-2500K @ 4.7 GHz now at 1.5v, it varies and is usually lower then 1.5v anyway. For some reason it's taking extra voltage to get stable 4.7 GHz stable on my chip. I am using a Corsair H80 Liquid Cooling System always on FULL fan/cooling 24/7. The chip barely gets past 60c while gaming full load. Is my chip going to start degrading or as long as I keep the chip temperatures low and everything it will last a long time?

I am leaving it because it is pretty cold in my room, AC on, temperatures have been staying pretty cool in the low 30's and no problems whatsoever. I ran prime95 and several benchmarks and everything.

  1. well, depends from chip to chip, but 1,5v its around the maximum limit. 60 degrees celsius its a decent temp for 4,7GHz. In theory yes, your chip should degrade over time faster but that depends on luck to :)
  2. I mean if it lasts for a few years that would be great. I also heard from Intel they run 24/7 at 1.52v (VCore). They have told me while in their chat support on the Intel website that it is safe, for my Sandy Bridge i5 chip. That is, as long as temperatures and stability is there, no blue screens, etc.
  3. I wouldn't do that, if I were you, not for a 24/7 OC, at least http://forums.overclockers.co.uk/showthread.php?t=18391925

    I don't care what Intel says, that's just one of a few things I've read about 1.5V+ killing a 2500K, sometimes in a matter of DAYS.

    The safe voltage (my own recommendation) is 1.40V or lower. Anything higher than that WILL absolutely shorten the life of the CPU significantly, worsening incrementally the higher you go.

    Besides that, you should absolute NOT need 1.5V for 4.7 unless you have a REALLY unlucky chip. I'd say 1.40V will should get you there and probably less than that.
  4. I guess I have an unlucky chip ;/ I can do 1.41v Level 5 LLC for 4.6 GHz though...

    Well, that does suck, but better to be safe than sorry, I think. 1.41V for 4.6 is extremely high as well, but that's a lot better than 1.5V.

    For reference, my chip can do 4.6 at 1.360V, and I actually consider THAT a bit too high, hence why I stick to 4.5 for now.
  6. I have a Gigabyte UD3H-B3 Z68X Motherboard, maybe I am doing something wrong with the BIOS settings, but I have followed some tutorials and stuff. Not sure what the problem is. I think I will back off to 4.6 GHz then.

    It's very possible that you just won the lottery that no one wants to win, lol. :( I've seen some amazingly good chips and some amazingly bad chips. Just luck of the draw. My own chip seems to be just about average though.

    I'm not sure it would change anything (it shouldn't, theoretically), but you can try using offsets instead of a manual voltage to see if that helps any.
  8. Don't switch it back to 1.41 LLC 5? I just did so it's not near 1.52v like it kind of was. I think it's safer now atleast and will last a bit longer at 4.6 GHz anyway. Temp is nice and cool around 30c and nowhere near 1.5v atleast, swimming around 1.4v as is.
  9. As long as you're around 1.4V, I'd say you're ok. The offset idea was just that. An idea. I don't really think it would have changed anything.
  10. Well atleast now I can be at ease of mind atleast knowing it will last longer and it is safer then being at the maximum voltage Intel or anyone has said is safe staying at 4.6 GHz.
