Intel Core i7-8700K Coffee Lake Z370 and Z390

Here's this, too...

 

Awesome @Mr. Fox ! Thank you for the tips and resources

 

Suprised you didnt grab a 7980XE @Mr. Fox . Enjoy the 8700k nonetheless. I think I am done with performance laptop as well.

Gonna make a good 7980XE based desktop machine for myself next week. I am switch to Lenovo thinkpads for my laptop need hopefully in the future.

Laptops just aint worth it anymore....

 

Well, I wanted that for sure. But, it would have been at least $1500 beyond the amount of cash I had to work with to go that route. I needed to spend almost that much on repairs to my wife's vehicle, so all a matter of priorities. I try to avoid spending more than I can afford. I could have used credit, but it's better to avoid debt as much as possible. I can always upgrade if and when I can afford it later, but I will end up earning more points on HWBOT by switching hardware configurations. So, there's no down side in that respect.

 

Absolutely avoid buying PC parts on debt, you made the smart choice for sure! I dont know how hwbot works, so no idea on that.

I dont think I am gonna aggressively OC the 7980XE to be honest. I would be happy with all cores 4.2ghz.

 

You earn points several ways. Winning (placing higher in ranking) is one, of course. Competing in competitive events is another. Submitting benchmarks with a wide variety of hardware is another. If you do well with all of the hardware you overclock and bench, then you earn even more points on top of the hardware points.

You can see points coming from a variety of sources when you look at a profile page.

 

@Mr. Fox did you happen to set the AC and DC Load Line to 0.01 in the BIOS? This was recommended on the Asus forums from an Asus Rep and it fixed the crazy high VID on Z370 motherboards.

No, spent the last two days getting Windows 7 figured out. I will give that a shot. My VID has not been crazy high. There was a BIOS update for my board already, so maybe it was addressed. My VID seems about right, but this is definitely worth checking. Thanks for the tip and link.

 

Look again... it appears ASUS says to set it at 2.10 not 0.01. The screen shot example shows the wrong value. I haven't finished reading and I could be wrong, but are you sure you read that correctly? I am not seeing high voltage or massive vdroop issues on my board.

---

Edit: I cannot vouch for the reliability of the comment, but it sounds (anecdotally) like the reason I am not seeing this issue is my motherboard doesn't have the problem that most other Z370 motheroboards have. Which is consistent with what I am seeing. ASUS ROG Maximus X Hero (WIFI-AC) seems rock solid. Glad I paid extra for it. Let's hope Clevo gets it right on their new Z370 laptops.

Here's this... *Official* NBR Desktop Overclocker's Lounge

 

The Great @Mr. Fox
Asus recommended setting it to 0.01, because that makes the VID what the CPU actually requests (and when using manual voltages, the VID matches the set vcore. Then you just have to compensate for vdroop with "Loadline Calibration" (LLC). They recommended this setting be set to 0.01 on all Kaby Lake boards.

I asked Raja what AC/DC loadline does and here was his reply:

2.10 mOhms is the Intel reference setting for Auto.
But I believe that is ALSO the reference setting for the MSI cancerbooks also.
If I use the "Auto" setting, my taptop shuts off (VRMs shut down) with prime 95 small FFT with AVX (FMA3) at 4.2+ ghz. The higher the ghz the faster the shutdown. Also the power draw seems to be sky high with the auto setting, and the VID is NOT shown accurately (someone explain to me how a VID of 1.14v can draw MORE POWER than a VID of 1.2106v?).
*edit*

If I use a "manual" AC/DC setting, anything above 1.30 (1.3 mOhms) also shuts off at 4.4 ghz (takes about 2 minutes however). At 2.1 mOhms (Intel reference setting=Auto), it shuts off in 15 seconds.

If I set my GT73VR cancerbook to 0.01 (1 in the Bios), the VID matches the set vcore almost exactly (Vdroop isn't shown), and the VRM's don't shut down at all.

I know you don't believe me, but I'm willing to bet you $20 dollars that that is why your 16L1 shut down as well when Prema had all power limits (Including CPU power limits being able to exceed 91W) at a high overclock. Because MSI set that value to "Auto."

You would need to change it to 0.01 and then increase the voltage. But there is a hard voltage ceiling on these cancerbooks.

Remember, MSI developed Battery Boost ™ right?
Well now we have proof they developed VID Boost ™ @Papusan

I was reading that thread.
There were people complaining about setting 1.3v in the Bios and getting 1.476v at load...
Then they changed AC/DC from auto to 0.01 and the VID dropped to 1.375 or something.

Keep AC/DC loadline at 0.01 boys.

*Edit* forgot pic: 0=intel 'reference' setting (Auto): 2.10 mohms most likely:

 

@Falkentyne , the power is lower on the higher voltage because the current supplied is lower. The behavior is explained in this old article https://www.anandtech.com/show/2404/5

 

I thought the current was a fixed amount?
Example:
The GTX 1080/GTX 1070 draw 19.5 amps because that is the rating of the power supply on the Taptops.
So 19.5 x 10 (a factor of 10 for the MXM slot) = 195W <--the maximum allowed rated power the MXM slot can deliver.

EDIT 19.5V NOT 19.5A SORRY.
https://en.wikipedia.org/wiki/Mobile_PCI_Express_Module

I dont know where this factor of 10 came from. Pretty sure d2ultima said this in an old post).

http://forum.notebookreview.com/thr...3-0b-alive-thread.795048/page-2#post-10318790

So what's going on with that AC/DC jokebook setting?
It's raising the AMPS but not the voltage??

 

? I suggest a crash course on circuit basics

Watts (total power, or "work") = volts x amps
Amps (current) rises and falls with load
Volts stays much the same so long as the power source or voltage maintaining components (VRMs) aren't too stressed by the load - we call this observation Vdroop - or if it gets below what the CPU needs to be stable... BSOD.

19.5V x 10A (195W) is the generally accepted safe longer term limit on the slot. That doesn't mean either the card or motherboard can maintain that and also be safe since a circuit is only as robust as the component that will fail first

 

Got an email late last week that the 8700k was in stock on neweggs website, was able to get one ordered before they sold out and cancelled my B&H order. CPU came on Saturday, excited to finally have it. I plan on buying a rockit delidding tool before I put my mobo in and put the cpu in it and start building. Is gluing the IHS back on needed or do most people place the IHS back on and clamp it down with the cooler? This would be my first time actually delidding a cpu myself.

 

I never glued them on laptops, but with the CPU positioned vertical as it would be on most desktops it might be a good idea. The relid tool works great. I used a very small amount of silicon and left it under pressure while I installed the GPU AIO cooler.

Congrats on snagging an 8700K.

The Worst CPU & GPU Purchases of 2017

 

It looks like Intel might ship Coffee lake 8 core z390 earlier than 2H18

Intel Z390 motherboard spotted in SiSoft Database
https://www.guru3d.com/news-story/intel-z390-motherboard-spotted-in-sosoft-database.html

Intel’s Z390 Motherboards Start Showing Up – Will Support Coffee Lake-S (Up To 8 Core) Processors, Arrival Due in 1H 2018
https://wccftech.com/intel-z390-motherboard-leak/

"The first Intel Z390 motherboard has just appeared on SiSoftware’s database revealing that the new products based on the upcoming chipset may arrive sooner than expected.

Intel Z390 Motherboard Appears Online – Will Support 8 Core CPUs, Arrival Expected Much Earlier Than Anticipated
The Intel Z390 is a not a new name that we are hearing of, it appeared months before the Coffee Lake-S launch. At that time, there was no evidence of why Intel was producing the chipset but later, we got to learn that the chipset will be designed to support 8 core CPUs that Intel will be launching in 2018 to compete against AMD’s Ryzen processors of the same tier."

Intel Z390 Chipset Spotted on Upcoming SuperMicro Motherboard
https://www.pcper.com/news/General-Tech/Intel-Z390-Chipset-Spotted-Upcoming-SuperMicro-Motherboard

"Specifically, the Intel Z390 chipset was spotted in a SuperMicro C7Z390-PGW motherboard along with an undetected 92W Coffee Lake 6 core / 12 thread processor (perhaps SiSoft is simply incorrectly reading a 8700K or it’s an unreleased slightly more power efficient SKU). More interesting though is the continuing tease of possible 8 core (16 thread) consumer Core processors being released for these new Z390 chipset-based motherboards. The rumor mill is going all in on salt futures on this one it seems. What we still don’t know is what architecture these rumored 8 core chips will use, whether Coffee Lake or Cannon Lake (I’m leaning towards CNL but an 8 core Coffee Lake chip, while large, is not out of the question.)

The Z390 chipset will reportedly add a SoundWire digital audio interface with quad core DSP, integrated Intel Wireless AC (Wi-fi + BT CNVi), integrated SDXC 3.0, and Thunderbolt 3.0 with DisplayPort 1.4 support (using the Titan Ridge controller). The chipset further supports C10 and S0ix

In the last bit of Intel chipset rumors for today, rumors are also spreading suggesting that Intel may be moving up the launch of the Z390 chipset to the first quarter of next year to better compete with AMD and its Pinnacle Ridge (Ryzen 2000 / Zen+) processors and Promontory X400 series chipsets (e.g. X470 and B450) which are allegedly coming in January. Basically, it’s going to be a crazy CES for motherboard and processor soft launches and product teases / announcements!"

 

Rushed releases make me nervous now, I will be interested to see how quickly they can get these up and to market but at the same time I worry they're being pushed out the door too soon.

 

4 Year Old Core i7 vs. Core i7-8700K, Worth The Upgrade?

 

z390 and then z490 for CFL 8 core and icelake 8 core not compatible good old intel need to buy a new pc. hoenstly though 8core CFL might not come so soon, perhaps in summer of 2018 which is Q3 or possibly even later.

remember eurocom's statement? F7 version of tornado will have z390 with 8 cores thats 2H2018, which is likely near the end.

 

@Mr. Fox 's 8700K 5.2GHz BIOS Tuning 10-Minute Walk-Through

 

Can a $7 CPU (x3430) HOLD UP Vs. The Mighty i7-8700K?

 

hey @Eurocom Support
this might be an updated intel roadmap for desktop, are we still expecting to see 8 cores CPU with z390 in 2H2018?

https://cdn.wccftech.com/wp-content...op-Client-Roadmap-HEDT-Mainstream-Entry_1.jpg

 

Smart move from Intel, not advertice 8 core now. It would decrease the sale of 6 core i7. They hope people with Haswell/Skylake or Kaby now will upgrade to Coffee as 8 core i7 don't show up in this roadmap. Directly from the textbook

 

so a good chance we'll still to see 8 cores this year!. i got from sources saying 9700k and 9800k and also 9th gen is definitely on icelake, and eurocom mentioned 8core coming for z390... what is intel hiding now, out with it.

 

THIS year? Nope

 

They're hiding announcements that'll have people deciding not to buy into z370/covfefelake and instead wait for 8 cores possibly in 10nm

 

Yeah, that's going to go over well.

 

Looks like an official road map to me, not sure what they're hiding and this information just confirms an earlier leak about their upcoming CPU lineup.

https://www.anandtech.com/show/1207...on-processor-lists-leaked-coffee-lake-refresh

The TDP of the CPUs listed match what they have on that leaked lineup. The upcoming 300 series chipset very well could simply be the unreleased non 'Z' 300 chipsets. The CPUs mainly look to be a small refresh of current chips, dual core CFL chips, as well as the low TDP CFL chips.

 

An official road map can be edited with a pencil within a few seconds I'm sure Intel doesn't want that AMD shall rule the mainstream all to long as they already have done. AMD have already 8 core who beats Intel's mainstream 6 core i7 and will most likely push out a refresh not too long. None like to loose a single penny!! At least not INTEL. Remember the greed

 

I'm just imagining someone taking a pencil to those and then scanning them in and posting it.

 

Umm no, it doesn't beat CFL, in fact it loses in a quite few areas. Gaming, content creation, and streaming all go to CFL.



I agree it can be edited, but going by the leaks that are actually out there and not just throwing darts in the dark it seems the road map is somewhat accurate. The 8700K is most likely already cannibalizing the 7800X sales, and an 8 core CFL ring bus architecture would seriously put a hurting on the 7820X 8 core mesh chip.

 

Stock R7 1800X beats 8700K. Even oc’d. All know Intel is good for gaming but more cores will have the extra. Hit up Bench scores for both and compare. Intel need 8 cores!! Even more after AMD’s push out their refreshed 8 core CPUs.

Intel will never sit down do nothing see AMD push out faster 8 core CPUs with higher IPC.

 

-- Again no it doesn't.. He uses a 1700 (same chip) OC'd to 3.9Ghz with fast ram for Ryzen and it still loses in a bunch of tasks. I've seen plenty of reviews comparing benchmarks and it just doesn't. Again if you pick a few select tasks sure it does win in some, and loses in others, but to blanket statement say it beats it is false.

For gamers and content/media creators the 6 core CFL is superior. Intel probably will release an 8 core eventually, but for now it seems the roadmap doesn't show that. Want more cores? Buy X299 is most likely Intel's stance.

 

I'm sure Intel will come up with a 8 core mainstream pretty fast although their road map don't mention it at all. Once AMD's new refreshed 8, 10 or 12 core chips is able to do 5.0GHz... What is Intel's answer to this? Refresh and push out 6 cores with similar clocks 4 or 5 months later? Or as you say push people on their *cheap* X299 platform if people want more than 6 cores? Nope!! This roadmap above isn't worth a ****y single cent!! More AMD rumors

Alleged AMD Ryzen 2 Leak Reveals 12-Core Ryzen 7 2800X With 5.1GHz Boost
"Anyway, it's going to be another exciting year. AMD set the groundwork to remain competitive for a long time to come , and the leaked slide underscores that. Meanwhile, Intel is preparing new CPUs of its own, including ones based on its long-anticipated 10nm Cannon Lake architecture. Hold onto your britches, folks." Yeah, Intel need to step up with mooore cores

Edit. Fake AMD Ryzen 2800X 12 Core 5.1GHz Slide Sends Media Into Frenzy
"The optimists among you will want to believe that this is true. After all who wouldn’t want to see 12 core Ryzen processors at as low as $329 and with clock speeds as high as 5.1Ghz, coming out on the 1st of February no less. The skeptics among you will point out that the specifications, pricing and timeline are all too conveniently fantastical. Sadly, the rumor has spread like wildfire with no evidence, other than the slide above, to corroborate any parts of it." Still, refreshed 8 core mainstream from AMD will push/hit Intel hard if Intel still want to go for 6 cores i7.

 

Exiciting times ahead! Finally the competition we have needed for the past 6 years is here!

 

Would be a lot cooler if it was real.

 

I tried watercooling an overclocked 8700k with a $19 waterblock

 

Hey @Mr. Fox , I've got my Clevo 870TM on the way, but my z270 from Dell needs a reinstall, weird blue screen and random USB issues. Did you keep a nice concise zip of the files for Kaby Lake around?

BTW, thanks for sharing the AIO zip.

 

The Level1 Techs 2017 Screeching Gamer Build! ft. MSI GTX 1080 Ti Gaming X Trio

 

i7 8720HQ spotted:

https://www.techpowerup.com/239809/...mobile-six-core-processor-spotted-in-the-wild

• BGA
• 45 watt TDP
  
• 6 core/12 thread - 2.4 Ghz with 3.6 Ghz boost
  
• 9-12 MB L3 cache (3 MB is somehow disabled, may be because of it being an engineering sample)
• Rivals i5 8600K in multi-threaded due to HT
• Q1 2018 launch

 

Cache cutdown to make up for added cores power requirements, that's too bad that Intel decided to neuter the part rather than upping the power requirement.

Intel could have kept the 4c/8t CPU @ 45w, kept full cache and upped this 8c/16t CPU to 65w

In it's reduced cache form, single core may not outperform the 7820HK both with unlocked power limit's.

We will find out after customers get them in hand, reviewers are too lazy to push the CPU's to find out.

 

It matches a 2 yr old 4ghz quad skylake in multicore while still managing to be 20% behind in single thread

I am unimpress

 

I'm assuming something like an 8820HK is planned?

 

Same not impressed. Multithreaded with an overclock 6700K will beat it and destroys it in single core performance. Meh. The unlocked versions surely will be more impressive.
