Intel "Coffee Lake" Builders Thread

Nope I didn't manage to snag a 8700k from newegg, but the good news is they sent me an email last night saying that I am getting a back order 8700k.Wonder just how long I will have to wait?If its anything longer then a month and a half I will just cancel.Perhaps I should get a i3 8100 for now to hold me over or should I just hold my horses and wait it out?

Booted up with no OC or BIOS settings touched and by default it has all cores locked at 4.7 on the Hero.

Quick temp test, no delid:

Nice mate! Does it lock all cores to 4.7 24/7 (so disable SpeedStep)? I would set it up manually later, as I'm sure you will, and get those volts down.

You have a nice system - why not wait a bit and see what happens. There have been some shops in the US that are showing larger supplies arriving in a week or two. I'm sure the situation will improve over time for the smaller northern European countries as well.

Edit: I do realize what a disappointment this is, I'm just saying look on the bright side since your system is perfectly serviceable for now.

Yeah I know that you are right, it's the mere disappointment after first not going SKL-X, then no CFL-S in August and now none upon actual launch. And had some days off to play with it as well. I've inquired and no shop knows when they can get them here, same for the Apex and one didn't even know if they will sell it to begin with ha ha. Also, I'm waiting with a few games I'm eager to play with the new system.

I did just get my RAM - looks very sleek!

All cores at 4.7GHz is an overclock 🙂

Plus he has his fans in quiet mode.

Just wait it out. You'll be glad you did.

Yeah I guess I will do that and maybe the extra month of wait time will give me enough time to add some more money to the GPU upgrade.

What are you looking at for a video card? 1070/80? Vega?

To be honest, the "back order" status to me was a fake thing. But we'll see next week I guess. If I don't get an update by end of next week I'm getting an 8400

If shopblt is to be believed (they put ETA and incoming stock status on their site), late October is the next batch.

That temp does seem a bit high for those volts (unless all review copies were golden samples). What thermal paste did you use?

AS5. Don't forget i'm using Prime 95 Small FFTs, so it'll be producing max temps.

Here is 5.2 when running Intel Burn Test:

 

[elhefegaming]

can you run it longer?

Pretty easy to hit 5.2? Or did you have to do a fair amount of tweaking?

 

[RichUK]

Yes, but I put my faith in P95 for stability testing.

IBT is good for a quick and dirty stability test to narrow in on stable frequency/voltage for avx and non-avx workloads.

Once it passes I move on to Prime95 v26.6 Small FFTs for ~12 hours. I suspect it won't pass Prime at 5.2 without a lot of voltage and a delid, if at all. I am hopeful for 5.1.

 

[RichUK]

Just manual voltage and multi (plus setting AVX offset), so seconds in the BIOS really.

Thanks. Damn, that's a sweet chip - 5.2 GHz at less than 1.3 volts!!

 

[Justinbaileyman]

Gtx 1060 6gb or Gtx 1070 ti maybe if the price is right? Dont want a Gtx 1080 or 1080 ti as the power draw is way to much for this house hold.

Not a real experienced OCer..... what should I set, like voltage to put my 8700k (when I get it) at 4.9 and forget it. I just want to leave it there and then never mess with it again. Anything else I should do?

 

[RichUK]

Looks like it's time to delid!

Prime95 v26.6 Small FFTs for 10 mins - 5.1Ghz @ 1.376v (no throttle, just):

 

[TheF34RChannel]

@RichUK You're going to do direct die cooling? You should buy a phase change Peltier cooler 😛

From your first screenshot, where the board auto clocked all to 4.7 I don't think 1.28v is that bad even; I expected the board would be 1.30-1.35v by default tbh.

Overclocking doesn't work that way; you can't put in a voltage and expect it to be done; trial and error by lowering it to the minimum stable voltage - every chip is different. Every board is different. That said, it's dead easy to do.

UK stock of K-CPUs expected to come in at 1 November... (as per OC3D)

Interesting tip. Not sure if it means same thing for US or it means US will get it before (I'd doubt that stock on US would be after UK)

So keep running Prime95 and lowering the vcore on passes?

Prime95 v26.6 Small FFTs for 10 mins - 5.1Ghz @ 1.376v (no throttle, just):

P95 uses avx, right? Why not offsetting AVX even more? Is P95 small FFTs even representative of actual real world workloads?

Real world varies by person really.

If you are going to be gaming, i'd say run 3dmark constantly and that's it 😛

Awesome!! That is super good news for me.. 🙂 can't wait I am so excited.. Just hope its true.

GamersNexus saw 10-20C lower after delidding and applying a better TIM. It's definitely quite temping to try it out! To note, GamersNexus also had a far worse chip that had a hard time going over 4.9GHz.
