How do you have temps that low? 1.39vcore set on a 4770k is pretty outlandish; there's no way i could do that with HT on without hitting like 100c encoding videos on "only" the best air cooling available with good ambients and no delid
I don't know, but I'm using HWMonitor to monitor 8 stats temps of CPU and GPU being some of them CPU usage never gets above 22% in games (WITH steaming/music/recording...without streaming, the load never gets above 10-14% --- not playing Crysis or anything like that but FPS stuff nonetheless with pretty good graphics on ultra etc)

I do not even think that I need 1.39 V but when you set the value z87 ASUS BIOS will color code the number (yellow is "moderate" levels according to ASUS and pink is "extreme" levels...1.39 is yellow, 1.4 becomes pink --- NONE of my values are set to extreme levels, but they if they are changed, then they are changed just a decimal point below extreme (pink color change) except for the capability one set at 140% - the highest it will go and another value (forget the name) set to '8' the highest it will go). If I hadn't delid, then I wouldn't be able to do this imo. I tried all kinds of other things too like changing the BLCK to 125, 167, etc etc to up the memory -- it did not like that very much and the multiplier had to be set low during that so...felt pretty subpar performance.

I don't know why my temps stay so low other than maybe I'm not using it for extremely demanding games like Crysis, BF4, etc etc. and of course it's delidded

don't know about the uncore, but I prefer the cache ratio be 1:1, but at 4.7 GHz I can Only have a 4.6 cache ratio...it hates 4.7 cache ratio (windows will freeze on startup). I notice the better performance in game when you have the multiplier set to 44 and the cache ratio set to 44 or the multiplier set to 45 and the cache ratio set to 45...46...46...but 47 and 47 is NOT possible with My system/chip, but....4.7 is so noticeable difference from 46 even with there not being 1:1, I'll take it...it's very noticeable To Me.

Why do you want cache ratio to be the same as core? 50/34 performs better than 49/49

What kinda temps do you have stability testing & with what test etc?

That's called placebo effect unless you have some kind of benchmark backing it up (:

Also, I did a reset to bios settings and when I set the voltage to override and set it to 1.22 while setting Vcore Voltage additional offset to Auto I find that it adds 0.08V to the total voltage which brings it 1.30V.
This didn't happen before resting the bios settings. I can't also set this offset voltage to 0. Instead I'm doing an override voltage of 1.21 and an offset of 0.01. Is this OK? or is there another option which "zeros" the offset?

No, 1.22v for x43 isn't out of the ordinary.

Figure out whatever voltage works for you, as long as you're not stressing synthetics on adaptive. I myself have not played with offset all that.

So now you know x43 is stable @ 1.22v. Work on x44 and don't touch x44 until you're sure it's stable. Sometimes what happens is, somebody does x44, does shoddy testing in excitement for x45, goes to x45, crashes like holy hell, goes back to x44, and crashes because it was never fully stable in the first place. When that happens, it's a real buzzkill.

That. Feelings don't count. An array of 5 tests or more that can be replicated and verified by other members is valid.

Hi,

I am new to overclocking as well as this forum. But I went ahead and took a gander at this. I only have an 212 evo since I am bigger on gaming more so than applications that are CPU intensive. Anyways, I currently have a i7 4770k. I was able to overclock it to 4.2 gHz with a vcore of 1.15 (1.153 in CPU-Z) on an Asrock z87 extreme4 mobo. Those are the only settings I changed, the multiplier and vcore. I ran prime95 (small fft) on it for about an hour and nothing went wrong yet. I tried vcores of 1 and 1.1 and 1.15 seems stable so far. The max temp I have so far on any one core is 77 C. So a few questions, but please bear with me since this is my first PC build.

- How long should I continue this test? After this time is my system good to go?
- Do I need to change any other options in my motherboard like CPU cache ratio or the voltage on it? Because currently CPUID HWMonitor is showing me LLC/Ring at 1.249 V, and since the cache ratio is on auto, I would assume its also at 4.2 gHz..
- What are some more complete tests that are recommended? I know people say prime95 for 24hours, is this blend, large fft, small fft? Aida64 is being used a lot as well.

Thank you.

As you can see in the original post I already tried x44 with voltage starting from 1.17 to 1.25 with no luck. I don't think I will be able to push this CPU past x43 without a significant boost in voltage which means insane temp spikes which my H100i can't handle.
It would seem this cpu is way below average.

I already outlined this on the first post of this thread.

 

I recommend x264 overnight, then just start gaming which is in itself a stability test.

 

Uncore to stock. Overclock core until you can't any more, then overclock uncore as much as you can without using unsafe uncore voltage or having to decrease core clock.

Drop cpu clocks to default, leave gpu OC'd, go play some games and see if it still freezes. If it does then it's gpu, if it doesn't then your cpu OC isn't stable enough for gaming.

I had this Problem with Battlefield 3 multi 64/player after several hours of playing, I5 4670K 4.6 was x264 stable. Then I simply added + 0.005 more Vcore and the Problem was gone.
So You might try adding 0.005-0.01 and see what happens. This is all under the assumption that Graphics Card is stable and not the Problem.

If that does not help I would try uncore like cyro assumed.

Personally I think your high uncore ratio is not necessary. I heard that high uncore ratio is only good in some applications and when benching.
