Btw I feel the best is to run this kit at 3866@c16
Performance diff is very small but latency should be much better

I'll try it out next weekend.

But I got to say I love this board n ram
Able to run such high CPU clock with so high speed ram with ease

Running integrated graphic atm
Maybe I might go higher after getting my gc and disable the 630graphic

Well I don't buy this kit just to see it will be downclocked
Keep pushing

Am encountering same thing as u. Not 100% post with 4266 xmp

After done tuning with the ram settings, 4133 should be able to push more bandwidth n faster than 4266. Pls let me know if u find a way to get the 4266 to run stable

my 1st adventure on ddr4...

Hi,
If you run some synthetic benchmark, like Realbench, what is the temperature?
My Kaby Lake core i7-7700k, I can only OC'ed to 4.8GHz, Realbench temp reaching ~88'C max, if I clocked higher I'm really not comfortable with the temperature.
But come thinking of it, our daily tasks (surfing, gaming) we don't push the core going 100% utilization like what RealBench does, maybe I should go for 5GHz? (without running RealBench to stress test)...as long as it didn't blue screen when I game, I should call it stable and good enough. Is this a good way to judge a system as stable, meaning running my own apps and games, without doing RealBench?

My temps for realbench is 60c+ at 5ghz. CPU is delidded
u can use 2 or 3 offset for avx to keep the temps down
i guess avx is hardly used in games or software at the current point

If i were u i will push the CPU to the highest with max temp under 80c
use p95 26.6 to test on the CPU stability. This version is without AVX
Then use a 2-3 offset for the AVX
Dont bother too much on the AVX haha

BTW you better off asking those sifu s here
im still new on this 7700k oc
but what i experience is 7700k is very simple to oc
its the memory part that is headache hahaha

First Pentium G4560 here!
I used to own the same Vengeance LED 3200C16 kit but never really had the time to push it until I decided to let it go.

The label indicated that it's using Samsung ICs, but no idea what's the specific type of die it used.

Realbench 85C max here at 5.0GHz under custom watercooling:


Well, OC stability is still a debatable topic since ages ago because of different experiences by different overclockers.
You can choose to skip stability testing, gaming without instability issue and call it stable, but some other people might think achieving 100% stability is a mandatory because they need it for their work. I'd say it's up to you to decide what you need.

RealBench uses AVX instructions thus generating a lot of heat. If you're not using AVX-based programs then there's no use of it. Gaming won't take any benefit of it. Like acther said, you can use the AVX offset to "control" the heat. For instance, 5.0GHz OC with AVX offset of 2 will reduce the frequency to 4.8GHz hence reducing the heat. For gaming you still get 5.0GHz with no speed reduction.

Regarding our 4266 RAM being unable to reboot at the rated frequency, yesterday I've actually contacted both G.Skill and ASUS HQ for advice.
Based on their reply, they are suspecting that weak CPU IMC might be the culprit.
Weak IMC means you will have to increase the VCCSA, VCCIO and/or VDIMM.

Looks like our journey is still long way to go, probably need another CPU to test out or even worse, a proper (extreme) cooling to "open" the IMC.

I'm encountering some prob also here. I'm very stable on 4133 c18. I try to tighten up all the timings n lower to c17. Hci tends to fail at the 200% mark for 3 days trying to play around with the voltage n sub timing still no luck. Any idea?

It sounds like you've hit the CAS wall at such a high memory frequency.
4133C17 is so tight AF.
I think 4133C18 should be good enough since you said it's stable.

Suddenly 4266C19 because of multiple failed reboot code 55/49, my OS corrupted
I've got a few 7700K coming to sort out whether it's really due to weak IMC of my current chip.

Are u sponsored? Can get so many CPU to try! Am trying to mess with rtl iol now to see if works

Gskill just announced 4333 kit also haha
Get n try it out when available

I also wish they are sponsored units lol.
Yeah that 4333 is crazy, can do 4500 19-19-19 on air

BTW, they also showcased 4500 16-16-16 during Computex 2016

Not just that, G.Skill is currently binning for 4400 kit, coming soon.

wow !

hahaha gonna order the 4500 when out woot!

But... still need to figure out how to run this 4266 properly first

gave up already hahah
saw a lot of ppl able to run 4133@1T with low voltage

i think we are having some weak imc

im like only 20% able to successfuly boot with 4266

whats the best stable speed n timing u get on the ram?

Good luck on that. Intel has shifted operations to Singapore, their involvement with Malaysian media has significantly reduced.

Even for past years I have to buy processors, I've been buying them since Haswell.

i think that's d last 1st & last entry for d chip bro, moving to Skylake i3 for some bclk oc fun (i know it's kinda late ). mine is ver 5.39, so not Ryzen ready hence it gotta go.
