Got my new parts 2 days ago and I started OCing today. So far I was able to achieve 4.6Ghz with 1.26v Vcore. Here are the settings I used on my Gigabyte UD4H:

multi 46
Vcore 1.26
Uncore multi 46
Uncore Voltage Auto
CPU VRIN override Extreme
BLCK Auto
Turbo Auto
C1E, C3, C6/C7 EIST all Auto

For stability I used AIDA64, run it for an hour, average temps were 64-70 across all cores and highest temps were 81-85.

A few questions:

1)Are these results any good?
2)Based on these results, would you say that my chip is above average?
3)Can we say that after 1 hour of AIDA64 the OC is stable?
4)Uncore to multi ratio is 1:1, is this ok? If not, what should I do?
5)Is there an option I can enable to have the CPU use less voltage and drop multi when it doesn't need the extra power? I beleive it's called Adaptive?
6)Any advice/opinions/extra tips are welcome :). I don't want to push the chip to it's limits, but I feel like I have some room for improvements ;)
 
I'm having fun playing with my 4770k atm as well......not as much as you by the looks of things :p
I cant answer all the questions,but i'll answer what i can


1)Are these results any good?

They look pretty good to me

2)Based on these results, would you say that my chip is above average?

i would say your chip is definitely a good one

3)Can we say that after 1 hour of AIDA64 the OC is stable?

Unsure as i'm currently stressing mine with AIDA64,if it runs fine for 10 mins then i'll try and reduce voltages etc to fine tune it,but i cant really answer if it's stable after an hour,would seem ok to me though

4)Uncore to multi ratio is 1:1, is this ok? If not, what should I do?

Thats excellent,not all 4770k's will be able to achieve a 1:1 ratio

5)Is there an option I can enable to have the CPU use less voltage and drop multi when it doesn't need the extra power? I beleive it's called Adaptive?

I haven't had much luck with adaptive personally,others seem to have,but i did set all my c-states to enabled in bios and that's dropping my voltages and core freq right down when i'm idle.

6)Any advice/opinions/extra tips are welcome . I don't want to push the chip to it's limits, but I feel like I have some room for improvements

you definitely have some room for improvement,although your temps are getting quite hot,
If your brave/Stupid enough to delid i think you would have a chip with great potential,it's just keeping those temps down :(

I delidded and with an h100i my temps aren't really getting much over 60 on all cores,it's just mine wants a lot more voltage to run than yours....around 1.35 to be stable at 4.5 :(
 
Thanks for your input!!

Regarding my temps, I don't think they are too high, they almost never got above 70 degrees with AIDA64, the 81-85 were the max values caused by spikes (I suppose).

As for delidding the chip, I don't think it is worth it and I don't have the guts to do it :p

Overall extremely happy with my results so far, I just want to make sure that the settings I changed are not going to fry my chip, I don't know why but I am kinda worried about the 1:1 Uncore ratio and Uncore VRing voltage(which is set to auto).
 
on your aida test you did remember to set in the preferences to use 1gb per thread ????? otherwise you wont be getting your uncore/memory stressed as much.
 
those are nice results buddy yes, and with the 1:1 ratio I'dbe well pleased :)

try changing your overclock to adaptive as that'll drop the vcore when not in use, works well on my mobo / cpu :)
 
After some reading I think I might have to lower Uncore and also set Vring manually instead of leaving it on Auto as it could run at potentially unsafe voltages... i knew my results where too good to be true lol.
 
yeah i was just about to post a update, no wonder you can get 1/1 uncore LOL

i tried auto on uncore once and it overvolted my OC gigabyte board by giving uncore 1.4v
8pack recommends no higher than 1.3v on uncore for 24/7 safe.
think everyone on the planet could get 45or46 uncore @ 1/1 ratio on vring voltage @1.4v lol
also set your vrin @1.860v with vcore @1.240v @45/43uncore with vring @1.250v

give that a shot ;)

Been busy today so I couldn't do any testing :(

Anyway, I feel like making a fresh start and tweaking only multi and Vcore to start with, maybe even Vrin and then work my way from there. My question is, let's say I give a random value of 1.9v to Vrin, 46 multi and 1.25v for Vcore, if I get a crash, how can I say which voltage out of these two needs tweaking?

with that much vrin if you get a crash its vcore related.
thats if you leave memory and uncore alone untill you find your cpus stable oc first.
 
Yeah this is what I am planning on doing, finding a stable oc then tweak uncore and memory.

I read that Vrin should be 0.4v above vcore, it is also stated in the UEFI, so if I set 1.26 vcore should vrin be at 1.7v?

does not always work like that, for instance 1.800v is the default or there abouts for the cpus default voltage and default speeds.
when you add overclocking into it that changes everything. depends on your cpu and what VID it has on stock and how much voltage it takes to get stable
some cpus require over 1.3v+ to get 4.5 ect and require 1.9+v to get there on vrin some even use as high as 2.0vrin

though most average chips require 1.850-1.90v+ you have to just test. 124 bsod`s require vcore or vrin if you want lower vcore add more vrin and vice versa.. though some situations with uncore stability or memory can cause 124s aswell.
Its all a ball game with haswell lol, for instance i can get stable at 4.5ghz with 4.3ghz uncore @cl9 2133 with vring @1.250 / vrin @1.870v and vcore @1.24v and my chip is classed as a good chip so i can just imaging what issues people are having with hot chips with bad imcs and ones that require 1.3v+

hell there are haswell 4770k chips out there that require 1.25v+ to get 4.2ghz stable. Its a lotto

------------------------------------

If you want a stable system at 4.5 i found it was not the cpu that was hard on haswell to get stable, it was my uncore and memory those are another ballgame messing about with system agent and analog and digital io aswell as vram voltage and timings, lot harder than getting the cpu alone stable trust me lol shoot for 2133 memory speeds and 4.2uncore for 4.5ghz cpu and then once stable try for a 4.3uncore ;)

Overclock day 2 results:

I started fresh today. Here are all the settings I changed:

Multi 46
Vcore 1.245
Uncore multi 43
Uncore Vring 1.2
CPU VRIN Override LLC Extreme
CPU VRIN Override Voltage 1.85
Memory XMP
C1E, C3, C6/C7 Disabled
EIST Enabled

Run AIDA64 with the above settings but 1.24 Vcore, crashed after 80 minutes.
Run AIDA64 with the above exact settings, crashed after 4 hours 10 minutes :(

I thought it was going to be stable after a decent amount of hours but it wasn't. Maybe if I add 0.005v to Vcore (for a total of 1.25v) then it should be ok. Or do I have to tweak other settings/voltages?

I feel like I am pretty close to stabilizing it, just need like another day of testing.

EDIT:Sorry, forgot to mention temps, probably because they are fine lol.

I never saw them go above 74, they were averaging high 60's/low 70's, max temps were 81-83 across all cores.
