i7 4770k overclock, how far should I push - Page 10

post #91 of 92
Nice write up there Klepp, some good testing done with voltages. There's not much 'real' info available right now for Haswell voltages and i reckon you've pushed it further than most by a good bit! The proof is in the pudding as they say so i'll keep an eye out for you on the forum and see how the chip gets on in the future, if you stick with it.

I'm not quite brave enough to push those voltages with the chip i have (performs reasonably well) but if i had a slightly under performing one i'd be willing to use it as a guinea pig and push like you have.

As far as the two conclusions go i agree, good chips are quite rare i think and correct in folks aren't using the same definition of stable.

I'm actually probably one of the people you are referring to as i run 5.0@1.35v. I've run this including each multi before it from x46 (excluding x47) for x264, XTU bench, IBT on high and 9hr XTU stress. I'm fairly certain i won't be Prime stable for hours on end but i've not had a bsod yet running the computer day to day. Which is funny when one guy on the Haswell thread ran Prime 28.1 for 16hrs then crashed gaming. Stability is subjective and because of that alone there will never be a reference stability for everyone to work to.

I reckon the decision should be an easy one for you, run 4.8 and go game or anything else, staring at the screen running prime aint much fun!wink.gif

Lol you must have quite the chip. I think your absolutely right though. 4.8 it is. I've spent so much time getting the first chip stable, doing it again with this one might kill me tongue.gif I hope I can buy myself a little room when I get my new liquid metal, I'm stuck using as5 right now and the temp difference is dramatic to the degree that I wouldn't believe it if I didn't witness it myself.

So to lend a little credence to the people claiming a 10c difference from TIM to LM. It's completely true. TBH in my case it's more like 15c. Fwiw it's going from naked die to waterblock with no IHS between but still.
