Haswell Overclocking Guide [With Statistics] - Page 260

post #2591 of 19637
My chip on stock uses about 1.14vcore max, but if i manually set stuff, i can run 4.3ghz on that voltage without really gaining heat, because voltage is much more important than clockspeed in terms of heat. You can probably get a pretty decent OC, depending on your individual cpu and how you did on silicon lottery

If you already have 2 case fans and are just running CPU stuff, then more probably wouldn't help you notably. I just ran a test on stock - running x264 full CPU load, my CPU went to 1.08vcore and 55w reported package power. In basic terms, case fans are responsible for removing heat from your case. If your hyper 212 was keeping the CPU at case temperature +30c max, then if your case was 20c, it'd give you 50c max, if your case was 40c, it'd give you 70c max, that's where case fans help. But with two case fans and just CPU load, your case probably isn't heating up much, 55w of heat going into the case isn't much at all. In contrast, system like mine at high OC on CPU with gtx770 at full load, can draw 300 watts in some cases, so that's much more of a factor for case cooling. Some systems will use for example an overclocked FX cpu drawing 250w, and a pair of 7970's drawing 200+w each, so they'd have 10x as much heat going into their case at CPU+GPU load. If you wanted significant improvements on CPU temperatures, you'd probably look towards higher end CPU cooling (212 is pretty low end) and not on case fans for that reason. 60c is not a problem though, and there's headroom on the voltage, i'd be surprised if you couldn't take 4.2ghz ok

CPU : 4670K
Vcore: 1.215
Core Multi: 45
Uncore: 38
Cooler: Noctua NH-U12S

Any tips to get higher? smile.gif

Does it make sense to overclock my chip above 4,5 GHz when i only do gaming?
Is a vcore of 1.264v OK on air? (CPU vid = 1,23v)
post #2594 of 19637
Menphisto that voltage is ok for air even 1.35v is ok if the temps allow it, and yes 4.5GHz is a good OC no point to go further if you are using 1 VGA with SLi 2/3 way it might give a bigger gain a higher OC
post #2595 of 19637
I believe for the 4770k 1.45v vcore is the maximum on air.

OK,thanks :-)
I go with 4,5 GHz because i only use 1 VGA :d
1,25v ring shouldnt be dangerous .....or? because With this ring voltage i also get 1:1 uncore to core ( only for the better look :-) )

i am testing the NB frequency and i got weird results, for instance i have better results with x38 (1.1v) vs x42 (1.2v) so i leave it at 3800NB and the CPU is at 4.5GHz (1.25v)
post #2598 of 19637
So i test 1:1 now, but my really best setting for performance is :
Core: 45x
Core Voltage: 1.2v
Uncore: 43x ( better performance than stock with my CPU)
Uncore voltage: 1.15v
RAM: 1600 MHz xmp
With these settings i got 7.65 cinebench score

Edit: you are right CyGnus 1:1 is ....****.... First it isnt stable and second it has a poor performance 4 runs cinebench and everytime around 7.55 and the 4th run freeze......so i have my absolut perfect settings Like i said biggrin.gif

Try cinebench with 38 or 40 and see the result's with me i have better score at 38 (9.83) vs 40 or 42 (not even reaches 9.70)

post #2600 of 19637
lol,the Problem which you have , i got With my stock NB ..... With stock NB i dont even reach 7.6 after 10 runs ...with NB @ 4,3 GHz i got 7.66 after 5 runs.....dafuq biggrin.gif
