Ok,
So i finally have my rig up and running which i built to be a decent overclocker.. I will get straight to my problem
I have a 4770k haswell which i am overclocking...
Yes i know they run hot and all the rest...
So my question is
So far I have achieved 4.5ghz stable, now I want to keep going however to achieve this I am going to have to exceed 1.3volts on the cpu core to maintain stability.. Temperature isn't a problem at the moment so no worries there, Is it 'safe' to keep going and pump more then 1.3v through my cpu i have read conflicting things. This is merely to see how high I can go and i will not be using as my every day cpu clock. How high should I go with voltage to be safe on the 22nm processor? I don't want to damage it...
Also what would be a maximum sort of voltage that would be good for long term use, right now I am looking at 1.295 Volts for 4.5ghz for day to day use?
I have heard there are other voltages I can increase to help with stability so I can back the core voltage off a bit? Fairly new to overclocking at this point in time...

Any advice or help would be appreciated
Thanks

I don't think 3D Mark 2011 is a good stress tester, I'd recommend running AIDA64 for 16 - 24 hours, you can find it here:

Let me know your load temps in AIDA64.

I'd say just stick with your current overclock however, for Haswell it's pretty awesome. Not much tinkering will bring it down regardless.

I'd say 1.3v is the perfect voltage, as stated by TTL.

I'd honestly stick with it, your overclock is pretty good as it is, and you could probably go a bit higher, but I wouldn't recommend it.

As for a safe voltage, as stated above, I would never go higher than 1.3v.

Out of curosity, what were your stress test temps, and how long did you test for?

Yeah my bios on my MSI Mpower goes red once i type in 1.3volts in core cpu voltage
My stress test temps over 1 hour plus running 3D mark 2011 never exceded 62c which is why im concerned about voltage, I have low enough temperature threshold to keep going but don't want to over do the voltage. I know I your suppose to test for longer but I was on a mission to see how far I could push it, if i decide to stick with 4.5ghz I will leave it at and run longer stress tests..
Cooler is the Corsair H110 with 2 aftermarket fans push 260cf of air per minute through the radiator.
So far i have only adjusted core voltage and cpu ratio to achieve me OC, are there other setting i could tinker with to bring my core voltage down?
Thanks for your reply
