Intel 8086K memory sweet spot between timings and frequency?

[storm-chaser]

I know I have a wide choice in terms of memory selection. As with any overclocking build, I want to take advantage of memory subsystem and DDR4 to the best of my ability.

Ideally what I am after are the tightest possible timings at the highest possible frequency. Specifically, I want to target the mid 30 ns range running the AIDA64 memory latency benchmark.

So far, from the research I've done I should be aiming for something like 4500Mhz on the memory with timings of something like: 17-15-15-32.. Does that sound about right?

Can anyone recommend a decent 16GB kit that is up to the task? Preferably without RBG lighting.

While we are on the subject, what is the best board one can buy for the 8086k in terms of overclock ability?

I take it I should delid the processor for best results? I'd prefer to stick with air cooling with this build, what's about the highest clock speed I can expect to run with air cooling?
I will be happy at 5.0Ghz, 24/7... is this feasible?

Also, how does the 8086K respond to NB overclocking? What is my target on that? is 4.5Ghz possible?

This build is going to be a dark horse theme so I want to avoid flashy RGB lighting and keep it stealth as much as possible.

EVGA Z390 Dark is your best board.

5.0ghz is easy for 8086. You should be looking at 5.2+, Batman build on this forum is good to go to for inspiration.

I could never do a batman build. This is going to be more SR-71 / F117 esque

I will post some pictures here and document the build once all the parts have arrived.

Im about a month out at this point.

Probably the cheapest Bdie 4400 kit The identically spec Gskill kit is like $70 more.

Beyond that its either going to cost substantially more and you're still going to have to get lucky with the IMC/memory modules/motherboard traces.

The Dark is really nice but its going to require a well thought out build due to the cpu slot being tilted horizontal @Arctucas has one and has gotten really good results from it with a 9900k


Why an 8086K? I'm guessing you must have gotten one really cheap because most retailers are listing new ones for $400 plus and for around $50 more you can get a 9900k at a Micro Center.

8086K + delid should clock exceptionally well, you'll want to opt for the 4400CL19 Viper steel bin (A2 PCB) or teamgroups 3200cl14-14-14-31 bin (also A2) both of which should play well with the Z390 Dark - for that board I'd entirely avoid any A0 PCB memory unless it's galax otherwise you're going to be very disappointed.

+1 for the 4400 c19 viper
they do 4000 15-15-15 for most users

I want the processor for its historical significance. And I may not even delid it after all is said and done, if I get good results right out of the box. So as to preserve the CPU in its original form. I've also seen very good latency #s from the 8086K, it's an exceptional performer.

As for build challenges, I'd prefer to take the more challenging route anyway. So what exactly is the problem? Fitment or clearance issues between the CPU cooler and memory? Any other issues with this board I should be aware of? In all likelihood I will proceed with the purchase not only for the performance potential but also because it matches the dark theme I'm after.

Just out of curiosity, has anyone been able to achieve a 5Ghz OC on the ram with similar hardware? That would be really cool if I could hit:

*5000Mhz CPU clock
*5000Mhz memory
*5000Mhz NB

I would be willing to sacrifice a little latency if this is in the realm of possibility.

damn,that 390 dark is a sick board,not available here.

If you're able to purchase multiple cpu/memory kits and a couple different motherboards I would say it's probably doable... otherwise you will need to get really lucky in the silicon lottery the hardest of the 3 is going to be 5000 on the memory with it actually being stable. 5ghz on the CPU will be easy especially with a delid someone here got 5.6ghz probably on chilled water (although my 9900k still beats it by 800 points in R20) not sure about northbridge but should be doable on a good sample.

Pretty sure 5Ghz uncore will also be quite challenging, to say the least. For memory he can get the uber expensive Gskill sets which do support it, but all in all that trifecta seems hard to achieve under anything but extreme cooling.

Yeah my guess is all 3 would be extremely unlikely to be stable for a daily system.... maybe for an R15 benchmark though

Huh, just $600 more than I'd anticipated

And then to run that frequency.....

Pray the sole single chip he purchases can run it.,
Might want to buy a good handful of these 8086K chips to test IMCs see which one is best from the lot.

4000mhz Cas 12-12-12 would be the benching place to sweet spot. CL14-14-14 is next to be ok at this frequency.

I run my 4266mhz sticks at 4300mhz 16-16-16, the IMC on the 8700K I have does not go further with any stability with this kit.

 

[sneekypeet]

That corsair kit only works with a 3600X and a specific (MSI iirc) motherboard.

 

[R0H1T]

The thing is DRAM at 4000MHz is already running way beyond it's rated/made for. It's like Intel pushing 8700k into 8086k territory or 9900k to 9900ks, every last MHz counts & is harder to achieve than the last one. Also IMO going for higher CPU will be better for system stability instead of choosing that 5GHz mark for all three, because I don't see the uncore & mem speeds allowing 24x7 daily operation.

 

[Deleted member 178884]

5ghz uncore should be quite easily doable on a 8086K that is a good bin - as for 5000mhz on ram you'd better run some horrible timings on b-die to even make that possible - it run makes more sense to suck it up and push for 4600mhz instead and crunch down on subs.
As for Rev.E (that corsair kit) it makes more sense on intel to buy B-die instead and just run them at awful timings to achieve the same effect, Rev.E literally runs awful sub timings to even clock well, and that's why they clock well. You might as well go 4400cl19, push ram volts to 1.5v-1.55v then aim for that 5000mhz goal and make sure to run CL20 or something similar.

Also, for another suggestion.....

Get the Maximus XI Apex instead of the hero for memory overclocking.
(Has questions at multiple forums, ours is slower with response rates, hopefully he waits for the Pro OC'ers suggestions from other OverClocking web sites.)

I was asked to review them, but in that ask were the requirements of what I listed above.

Sorry, just looked back at the conversation.....needs a 3600X and MSI X570 ACE!

I'm not arguing anything an AMD setup can do.
I simply copy pasted the Newegg details about the memory.
That's all I have to go with at this time.

Again.... My 8700K doesn't like faster than 4300mhz. I'd have to bin a bunch of chips in order to get any speed faster than the current I have been using at this time.

See my edit above In my testing, if you want fast ram and Intel, you need a 7740X without going to "extreme" measures for something that should just work. Even then, mine tops out so far in the 4750-4800 range, but I may be limited by the ICs/voltage I use and not the IMC as its been pushing 4600MHz kits to get there.

Why?

I have this awesome overclocking database to look at??

Memory Frequency overclocking records @ HWBOT

Overclocking records

hwbot.org

Note: Top place is with 8700K and HOF memory kit on LN2.

You guys are talking extreme clocks for a daily gamer.

This is because we deal in the realm of the OP, where he states.... "I will be happy at 5.0Ghz, 24/7" That to me means he wants to accomplish this in a daily driver, not for LN2 suicide runs. My experience plays into what he is looking to do more than some list at HWBOT with ~2V to the memory under "extreme" cooling, which I also mentioned in my above posts.

You could always just get an actual 8086 off ebay for $5 if your looking for historical significance.
IMO an 8086K has no "Historical significance" since it's just an 8700K with a different name.

Yup it's just like that 50th (?) anniversary edition from AMD.
