Intel Core i7-8700K Coffee Lake Z370 and Z390

@Talon possibly got a real good sample tbh, his chip is possibly equiv to 1.35v for a 5.2ghz run on p95. we need a chip like his to be able to use it in laptop though, or else we expecting a 4.8-4.9ghz.

if i do get my cpu im gonna disable HT regardless to shave off 10-15c

 

You may have found the bottom, but setting voltage too low will impair performance. Put it back up around 1.265V or 1.270V and test again. 6700K and 7700K also lose performance if voltage is set too low. The score next to yours is 5.0GHz. The other two are 5.1GHz and 5.3GHz. You can also increase power limits and that may help. That will have little or no effect on temperatures.

Exactly. It just like with the Pascal GPUs where the performance can be severely limited when you mess with too low of voltage setting. I notice it when running CB and shaving voltages. The score difference however is pretty small though and my testing was simply to see just how low I could go for the gold standard 5.0Ghz on this chip. I don't think voltage differences are making up the gap in scores between mine and his scores at 5000Mhz though. I looked at a few other scores at 5.0Ghz and they seem more in line with what I saw. I did have background apps monitoring performance and doing an OSD so I could see all clocks and voltages in real time.

5.1Ghz 1.350v (it passed at 1.325v as well)

Maybe based on the number of pre-orders they have in their backlog or something. But, as we all know, there is no accountability when it comes to advertising. Who knows if it is accurate now, or any other time. Merchants seem to be able to make up crap like that all they want to and not have to support it.

Even if it was in stock at NewEgg, $419 USD is price gouging. It should sell at retail for less than $400... $375 max.

Gigabyte Z370 Aorus Ultra Gaming Review

Glad I went with ASUS. Just the name Aorus turns me off because of their crappy laptops. I'd avoid that motherboard for that reason (association) alone. A curse, like naming your son Lucifer, LOL.

 

http://gph.is/XLlIZH

 

Dude, You Bought Power

 

Just got Windows set up. Used the "Easy" mode in the Windows tool and set 50x6 and let it set everything else automatically. No fine tuning yet or anything. Can't wait 'til I am finished installing crap and I can lower the voltage and see what it will do.

Here is the first benchmark with nothing optimized.

 

laptop cant hold u.2 or 15mm ssd form factor. if i gone destop i'd be getting those and theres no laptop m.2 optane ssd yet except for those 32gb cache drive. get 900p mr fox and pair it up with your 5ghz+ overclock your computer will feel super fast.

 

Definitely going to have to delid the CPU tomorrow and put some respectable paste on it to get the temps lower. It has the wax pad crap that ships with the AIO unless ibuypower put something else on it. Imagine what it would look like with air cooling. I'll run some GPU benchmarks, too. (Still haven't installed much stuff yet.) That way we can have before/after comparisons once I slap the GPU liquid cooler on it. But, yeah... this seems really nice. I like it @Talon and @Papusan.

 

Makes me miss my build right now 4 days off coming up and want to get some serious time in with Wolfenstein 2.

 

Here are a few more pre-delid/air-cooled GPU fun runs...

Vantage, 3DMark 11 and Sky Diver would be higher scores on Windows 7, but I'm not done installing stuff on Windows 10 yet. I'll save the best for last.







@D2 Ultima @Phoenix

 

Looks like a good CPU sample. Check the voltage for 50x6.

@Papusan @ole!!! @Talon @bloodhawk @Johnksss@iBUYPOWER @Jon Webb @Prema

 

Would be nice if you could run stock clocks in bench for later verify the scores vs. stock Coffee in Clevo laptops. If you have time

 

I will do that.

Definitely going to have to delid tomorrow. wPrime 1024m reached 94°C. But, still decent scores. Note voltage and watts.


EVGA 1080 Ti SC2 has some nice features available in Precision X (voltage, K-boost, etc.) that I wish we had in notebook 1080 GPUs.

Lots of GPU temperature sensors on iCX GPUs.
@dspboys

 

Thanks. Wold be nice if you could run stock voltage. Aka apples vs. Apples. I don't know if voltage will be the same in Clevo, but Oh'well. Then we will see what we can expect from the cooling in Clevo models.

 

I will run wPrime and Cinebench with BIOS defaults before I delid tomorrow. Time for bed now (2:38 AM).

Only minor complaint so far: I wish the case fans were white instead of blue. Not a big deal. Looks OK. I might have to get rid of those two fans (not RGB) and put some in to replace them with no LEDs so I can make all of the other LEDs white.

Highest power seen on 1080 Ti SC2 was just over 300W with 2062MHz core OC. Highest on CPU about 142W. On the PSU meter, about 500W max. So, still have headroom on the 1000W PSU to add another 1080 Ti SC2 later if I want to.

 

The dark blue color looks nice, subdued, the computer easily moves into the background to be non-distracting.

When I've had White lights / bars I've always used channel dimmers and timeouts to have them fade over time and then turn off.

I find the dark blue's are the best to disappear when I am not interested in the computer drawing attention, but useful when I need to look inside.

Even my daughter that liked the RGB lights initially, and the sound (music / voice) activated lighting, wanted it all pulled out after a while. Everyone she showed the lights and controls wanted to play with the controls, and that got old after a while.

I like a completely dark build behind sound proofed sides, which is best when you want quiet and don't need the lighting. It also saves you from spending all that time dressing cables for looks instead of air flow

 

Looks good to me brother. Any 8700K that hits 5.0ghz all cores seems to be a better sample. I’ve read numerous posts on reddit of guys not getting 4.9 or 5.0ghz stable.

Can I ask what BIOS settings you tweaked/set?

 

I am off this whole week. Glad it got here by Wednesday.

Going to have to run to Fry's and grab two more SATA cables for my 1TB Samsung SSDs.

Initially, I just set 5.0GHz in one easy step using an ASUS profile and it worked fantastic, although the voltage is a bit high using the profile.

Do you know if ASUS overclock profiles are individual system specific? I can export what I have to save for myself or, if not system specific, share with others. I tweaked a number of things, so I will take photos or make a video for you. Since this is all new, I am not sure I can remember off the top of my head. I know I changed everything that I saw has an "Extreme" option available and set it to that option to avoid saving power, and set the PL1/PL2 to 200, Turbo Time Window to 1. AVX offset wimp option turned off. Spread spectrum and c-states also disabled.

I see ASUS already had their first BIOS update, so I flashed that last night. What a strange experience compared to what I am used to. My private parts where hiding for a bit. Took a lot longer than a @Prema mod and several reboots that are normal, but I was still biting my nails.

It is cool that the boot logo shows the overclock percentage (currently 38%) in a fancy gradient font.

 

No need to worry about flashing. They have a bios flashback feature. Plug in your bios flash drive and push the button.

Old vid, but same concept.


Not to mention 10 save locations for your bios settings, plus saving to flash drive.

 

Yeah, that is awesome. Thanks for the info. I did not know that was possible. Sweet.

 

No problem.
And the bios can be edited and flashed as well, but generally speaking on these boards.... Most options are already unlocked and actually work.

 

I doubt. I think they're just not doing things well or have a bad board.

They aren't, afaik.

Might I ask why you didn't get an X299 platform? I would've expected you to put it together yourself with a full waterloop system xD

 

Ask and ye shall receive... BIOS defaults for CPU. I reset optimized defaults and only set the RAM to 3200.

 

Yes... one word: money. I needed about $1200 of what I received from selling the DM3 and TF5 for repairs to my wife's vehicle. The only reason I went with 8700K was it is the best CPU available within the budget I had to work with. The only reason I went with ibuypower is I could not buy an 8700K anywhere and they are the only system builder I would trust to send me something done right, and price-wise they can match or beat what I would spend buying the parts on my own.

I wanted an i9 Extreme, 1080 Ti SLI and chilled water cooling and that's would I would have had if budgetary constraints were not a concern. But, now that I have it I am really pleased and I, overall, am impressed with the dealing with ibuypower. I purchased an old gaming notebook from them like in 2007. I wasn't impressed back then, but they have come a long ways in 10 years. They're pretty awesome. You know they have to be a good company or @Johnksss@iBUYPOWER would not be associated with them.

I ended up spending right at $3000, including the 144Hz 1ms ASUS monitor that I got from Walmart.com and the EVGA hybrid closed-loop cooler I got from B&H Photo. Can't beat it for the amount spent.

 

Bios default is 4.7GHz for your setup. But 8700K default is 4.3GHz on all 6 cores (4.7GHz single core). No in HELL Clevo will throw out firmware with default 4.7GHz all 6 cores

 

There are plenty that cannot at least with Intel TIM hit 5.0Ghz unless a large amount of voltage is applied and even then still not stable. Look at GamersNexus release video where 1.420v still didn't give them 5.0Ghz stability. My first 8700K took 1.4v basically to get to 5.0Ghz and still didn't seem stable at all. My current chip only takes 1.250v BIOS and loads 1.232v and has yet to show a single sign of crashing or failure at that voltage.

@Mr. Fox the Asus 5.0Ghz profile is NOT chip specific and applies a stupid amount of voltage.

 

Mine doesn't crash with lower voltage, but performance decreases. Best benchmark results are around 1.350V.

I delidded and put Conductonaut under the IHS, Phobya NanoGrease Extreme on top and installed the GPU water cooler. Temps are awesome now. I was able to increase voltage and watts, improve benchmark scores and still running about 18°C cooler, LOL.

I will post results tomorrow. @Papusan is going to like them.

 

Compare temps to previous screen shots (two thread pages back) before delid and GPU water cooler. @Papusan @dspboys @Johnksss@iBUYPOWER







@D2 Ultima

 

Before.

Now. But with higher Cpu Package Power(increased volt and Cashe but lower temp)

 

Do more with more. Doing more with less is code word for compromise. The end result is most often the opposite and you do less with less. The best approach is to do what is required.

 

Finally made it into the top 100 in my overclocking league.

 

how much penalty were to happen if you were to lower the voltage?

 

See the before scores. Not enough penalty to matter for normal use, or playing games, but it does for benching. Now that the temps are under control, there is no point in using a little bit less voltage. Doing so is not necessary. Using less than optimal voltage carried a similar penalty with 6700K and 7700K as well. Still stable, but lower performance.

 

The liquid cooling on the 1080Ti was a huge benefit in terms of holding clock speeds on a benchmark like Heaven or Superposition. GPU core boost clocks were the same at the end as they were at the start. As expected, they were dropping on air cooling as the GPU got warmer.

The 8700K thermal paste under the IHS looked worse to me than what I had seen before on 6700K or 7700K. It seemed abnormally dry to me, especially with only 24 hours of use, plus whatever burn-in testing was done by ibuypower prior to shipping.

 

ic so roughly a 1.5% penalty small enough.

 

Oh my, voltage that seems to sit at what you tell it to sit at... what forward-thinking innovation in these new chips!

*hides all evidence of any processor prior to Skylake*

 

As expected... physics score of W7 destroys W10 [ Compare]

5% penalty for running the cancer OS, LOL

@dspboys - Getting Windows 7 to work was a HUGE pain in the booty. Wasted an entire day on it and could not get it to install due to Intel 300 series chipset RAID/AHCI controller drivers not working to install Windows 7. I never found a solution. Maybe Fernando at win-raid will mod some in the near future so it will install normally.

So, I restored an image of W7 from the P870DM3 to one of the 1TB Samsung SSDs and *BOOM* worked. That's using the 200 series RAID/AHCI controller drivers. Changed the product key to a new one and re-activated Windows.

Anyone buying a Clevo with 8700K that wants Windows 7 needs to be sure to save an OS image in case no Windows 7 drivers are available for Coffee Lake by the time you get it.

Macrium Reflect FTW @Phoenix

 

Problem solved: Fernando at win-raid rocks. @Prema - in case any driver stuff is needed for Z370 notebooks with W7.

https://www.win-raid.com/t3146f25-update-SATA-AHCI-Controller.html#msg43183

Now chipset is correctly identified in Device Manager (no longer 200 Series) and we have INF files to integrate in the Windows 7 USB setup thumb drive.



@dspboys

 

There's a performance penalty for all of those Windows 10 features, data collecting of your activities, creating those reports of your activities, and then sending them off to who knows what end point(s).

You should be proud for doing your part to destroy "Personal Privacy" by running and supporting the use of Windows 10, that 5% performance loss is a small sacrifice for your participation, more sacrifices to follow...

 

Yup. And, as if that were not enough, performance is not the only penalty. There are also moral and morale penalties for using the suckiest version of Windows released since Windows Millennium Edition. By installing it we are all contributing to the delinquency of an exceedingly corrupt entity.

 

Solution is simple: Don't install Windows 10.

 

And, for those planning to move to Z370 chipset, here are the drivers I used to integrate into Windows 7 with the MSMG Toolkit. I just finished a crisp new Windows 7 Ultimate installation onto the 960 Pro with no errors whatsoever. I only had to install Intel ME drivers and WiFi drivers when I was done. Those were the only two "unknown device" in Device Manager.
