Hey everyone,

I've been having a go at overclocking my 2500k tonightband have manages to get it down to 4.8Ghz and 45mins of prime and intel burn test stable at 1.4Vcore, however i can get 4.9 out of it but it isnt ITB or P95 stable (havent tried 5GHz yet) but what i was wondering is, is my vcore safe for 24/7 use? If not then what would you say is? Bearing in mind intel have said 1.52 is the vcore max?

Setup:
2500k
Asus z68 v pro
4GB corsair vengance @ 1333mhz
HD 6950/70
TX650

My bios settings and temps:
intel burn test : 70C
Prime 95: 65C
Idle:25C
PLL: 1.9v

Any help or ideas are appreciated sooo much, thanks! :)
 
Much of an unknown *really*, but the general consensus say do not exceed 1.38v for a daily overclock.

Im stuck at 4.6Ghz using 1.375v but im happy to have it running their all day long :)
 
Ahh right, thanks for the reply,,

Will try and clock it down to 1.38 and if its not stable any chance i'd get away with 1.39? Whats the lifetime limit on running it at 1.39/1.4 daily? I only need it until ivybridge or haswell,,
 
That's where the unknown came in, no one is really sure.. at least there hasnt been any proof about volts/lifetime damage.

Its a guideline, but any more than what's suggested, most would say try and lower the clock a little and get something stable on whatever volts you can manage.
 
hmm, okay then mate :) current got it doing intel burn test on a 102 BCLK making the clock 4.899GHz on 1.39v, May try loosening the ram timings consider i havent even tried that yet :) thanks for the help,

But do you guys think i'd get away with 1.39v? or is it just better off taking it down to 1.38?
 
Update: can set the multi to x49 for 4.998GHz and boot into windows at 1.395v however im not too sure if ill take it down to 4.9Ghz at 1.39V yet, if im prime stable on my current 4.998 imma leave it at that :P
 
To be honest, if you only got a single 6950 unlocked to 6970, I don't see much point of your overclocking beyond 4.6GHz...as it won't really give you extra performance since games are going to be GPU bounded. It's not worth it with the extra power consumption, instability (with tempering with the base clock) and risk of damaging your chip.

I don't think it would be worth it either - but each to their own of course.
