4690k @ 5Ghz?

[savagesam117]

I want to push my chip a little further, it's plodding along at 4691Mhz or close since the day I got it at 1.25 v core. I have just water cooled it so it's now maxing out at 55c in real bench and is as stable as a rock.

All I done was changed the multiplier and v core. I have tried to read up on it and there's so many different names for stuff in different bios, I'm confused!

Spec is in my sig.

Should I expect to get it running at 5Ghz, 24/7? Is it possible? Some help would be much appreciated

No , at least not 24/7 imho but that depends on how much voltage it takes you to hit 5ghz . As you climb higher more voltage is needed per MHz extra , you've got a fair bit of headroom to push a fair bit further temp wise but how much voltage required to get to 5ghz will be trial and error , if the CPU is capable of that within thermal limits and without throttling. As far as I'm aware the Devils canyon revision hasn't really made that much difference for haswells temps at high clocks . I try to stay below 1.3v on the core for 24/7 clocks but quite happy to run upto 1.4v for benches . Purely due to degradation ( debatable but I feel better ) .

From 4.6 to 5.0 you're really not going to see much improvment bar benches however I do think hitting the uncore will be more appropriate in terms of visible performance increases . Unsure what z97 / 1150 is capable in terms cache overclocking as Ive only really focused my time on x99 with it . So perhaps someone could help here , as far as I know ideally in a perfect world your uncore should be 1:1 with your core clocks for best results . But again I'm unsure what standard haswell without an OC socket is capable of

I've had a bit more of a fiddle and got the uncore at 4.6 and got the core up to basically 4.8 with 1.275. And is stable.. From what I've tested and played so far. I'm not sure what voltage to use for the cache though? I tried to go for a 1:1 but it would crash as soon as windows would start to load, I guess more voltage is needed? Temps Average of about 58, max of 62c.

I'm not expecting to see much I just want to see how high it can go
