Intel Core i7-8700K Coffee Lake Z370 and Z390

I assumed the link was yours for the 5.3GHz validation, so that is why I asked if CPU-Z reported it incorrectly.

 

Well, the monitor arrived. Now I just need the PC to go with it, LOL. Working nice with Machete for now. It has a couple of features I will never use... Adaptive-Sync/FreeSync and NVIDIA 3D Vision.

 

Well, my 1080 Ti FTW3 Gaming iCX was sold out with no ETA, so I exchanged it for a EVGA GTX 1080 Ti SC Black Edition and EVGA Hybrid Waterblock Cooler. Wasn't looking to spend the extra $100, but now I can do a before/after video on GPU thermals on air versus water for my YouTube channel. Should be fun.

Here is a look at the internals of the cooler, which includes copper vRAM cooling mated with the water block and discrete cooling for FETs and VRMs.

Where is your motherboard and 8700K coming from? I managed to source a second 8700K which I will be picking up Saturday morning when I get home from a trip. I plan to test it against my current one sell locally on Craigslist the worse chip of the 2. Hopefully with this shortage I shouldn't have much issue dumping it quickly.

 

ibuypower.com - could not find an 8700K for sale anywhere except through system builders. I found B&H Photo had them for pre-order with no ETA, but Micro-Center, Frys, NewEgg, Amazon, Silicon Lottery and other vendors did not even list 8700K in their online product catalogs. I even tried Google shopping search and zilch, nada... LOL. Where did you find them for sale?

 

I grabbed mine from MC online last night. Happened to be awake at wee hours in the morning yet again and they had one in stock so I quickly added it cart for pick up reservation and it went through this morning. Got the email telling me it will be held for me until Saturday closing hours. Luckily I get home late Friday night so can stroll in there Sat morning and grab it. I've been told they will price match Newegg/Amazon/Tiger Direct and have always never been denied this in past from them.

 

Sweet! Congrats. Have you already delidded it? https://rockitcool.myshopify.com/products/rockit-88

I just checked the web site and verified my existing Rockit88 delid tool is confirmed for Coffee Lake CPUs.

I have not delidded it yet, and that would most likely get voltage required down quite a bit since I should have less voltage leak with the temps. I'm still debating whether or not to even try my luck again at this damn silicon lottery. I mean I am currently sitting at 4.8Ghz 1.250v on my current chip and it's been rock stable. I have been shaving down 10mV at a time and testing for a few days. Trial and error but eventually I'll hit bottom on the voltage. 200Mhz probably isn't worth the headache and Obviously I can run 4.9Ghz on all cores too. 4.8Ghz at lower voltages was more appealing to me though. A delidd would most likely get me 5.0Ghz stable but I was hoping to get it stable without the need.

 

Yes, it should definitely help. I've delidded my last 6 CPUs I have had and I cannot even imagine not delidding at this point. For me it just seems silly to not delid. I plan to delid my 8700K immediately. I will run a few benchmarks for before/after comparison purposes only. Will likely have the lid off with liquid metal on it in less than 24 hours.

I'm going to be shooting for 5.3GHz or higher. I cannot afford a water chiller and custom loop yet, so that is why I went with a 360mm radiator exclusively for the CPU and discrete cooling for the GPU.

EKWB has a nice CPU/GPU kit for a reasonable price, but it is only 240mm shared with CPU and GPU and a small reservoir. Should be great for gaming, but not really for heavy overclocking. Plus, the cold plate on CPU and GPU are aluminum, so I cannot use Conductonaut.

https://www.ekfluidgaming.com/ek-kit-a240g

 

What a flawed (Dellienware) design... Aluminum, LOL

 

Yes. Copper is much better. Not sure why EKWB did that. Apparently, they are targeting a niche that wants to spend less and get less. Would still be a huge improvement over air cooling. It's not a terrible deal, but not suitable for what I would expect. Should be nice for playing games with stock clocks or very minor overclocking. That kind of sums it up for most gamers, so I think there is a place for it. Just not here with guys like us.

 

That's marketed as a budget overclocking kit though, so it's understandable if it's made out of aluminum.

You can still buy the normal kit which is more expensive which includes nickel plated copper coldplates for the waterblock.

 

So I can use the same rockit kit I used on my 6700K and 7700K for 8700K? Yasssss

 

Z370 - BATTLE of the CHEAP (en) - THANKS!!

 

I went to Microcenter the other day with a friend to help him pick out a 1050TI to put in a workstation I am giving him that cannot upgrade the PSU and does not have 6pin power connectors on it, while we were there I was looking around at stuff I could use for my build and everything was a bit more expensive than I could order online, but the motherboard I wanted (Aorus Gaming 7) was the same price so I decided to buy it. Brought it up to the register and it rang up $50 cheaper than the price tag and normal online retailers list it for. Did not expect to get any sort of savings on a new product like this, not too shabby.

 

Well, still no PC. Was supposed to ship today. I called to confirm that and was told the case was out of stock. Two days ago I got an email stating all the parts were gathered and it was going to build status immediately, so go figure. I had to chose an alternative case today instead of it shipping today. Ended up settling for this option. Not terrible, but not quite as good as what I originally selected. http://www.thermaltake.com/products-model.aspx?id=C_00003012

At least I received the monitor and the GPU liquid cooler on time... Cooler came today. B&H Photo shipped it 3-day delivery for free.

 

I like B&H Photo, I had 3 day free shipping on my Corsair 570x that I ordered from them and it came in 2 I believe. My 8700k has free next day shipping from them and I am close to them on the east coast so once they ever get them in stock I should have my CPU and be ready to get soon, it's just a matter of waiting for them to get one as I see them coming in and out of stock on Newegg and other sellers every couple days = \.

 

Getting closer. Maybe it will ship on Monday. I can see now why @Johnksss@iBUYPOWER likes being associated with them. (I haven't been to their location, but John has and I understand it's a pretty impressive operation.)

If the hypothetical 8700K were available for immediate purchase from a parts retailer I would have built this myself as I have always done in the past, with an open bench instead of a case. But, pricing out the components, I really do not believe I would have saved much if anything. They must buy at a great discount in large quantities. While I am missing out on the joy of putting it together, I do remember the hassles of building systems for myself and customers whenever I ran into a DOA or malfunctioning parts that had to be RMA'd and what a pain in the butt that was. Didn't happen very often, but when it did it always sucked. Maybe not having to bother with that will be nice. But, I will be tearing it apart almost immediately anyway.



Including the 144Hz monitor and EVGA GPU water cooler I will have about $3100 total invested in it, so not too shabby. That's with me bringing my own 512GB 960 Pro and two 1TB 2.5-inch Sammy SSDs to go with the 2TB HDD they are providing and my own W7 and W10 licenses.

I was getting irritated about the GPU and case not being in stock and having to find out a couple of days late both times. I caught this video on YouTube and now I'm a little bit less worried about what it's going to look and run like, and whether or not I will regret having someone else assemble it for me. Pretty good video, actually. If it turns out good I will have to do something similar.

 

You also know they make cases with the side panel glass as a transparent LCD screen...

 

That's pretty slick. I did not know that. I'm still planning to replace the case with an open bench when I have more cash. Too bad they don't offer those. I wish they did.

Until then, the black case with tempered glass will look nice on my black tempered glass desk.

Thanks for the help today. I appreciate it.

 

Dang, looks like they made a lot of progress today. Awesome.

 

Just installed my second 8700K. First test 5.0Ghz at 1.3v running stable and getting highest CB scores I've gotten. Will now start tweaking to see how high I can get and how low the voltage can go with highest clocks. This one looks like a winner! Sold my first chip to a craigslist guy with a brand new z370 board for exactly what I paid. I didn't make any cash but I got a second chip and a lottery winner!

5.0Ghz all cores, no offset, 1.275v with LLC. Damn Asus board (strix) has still has some crazy vdroop at LLC 6. LLC 7 (max) seems to remove this issue entirely and I get a tiny tiny bit of overshoot. This is stock Intel TIM, no delidd, and a hastey repaste after swapping the CPUs. This chip is leaps and bounds better than my first go.

@Mr. Fox may the silicone lottery odds be ever in your favor.

 

Sweet! That's a mighty impressive hexacore overclock and Cinebench score.

I hope I am as fortunate in the silicon lottery as well.

 

55lb, what did you order thats so heavy.

 

Desktop with a tempered glass case. The only other thing that might be a little bit heavy is the liquid cooling with a 360mm radiator. I'm guessing mostly the case since both side panels and the front panel are like 5mm thick tempered glass. I don't know if the chassis part of the case is steel or aluminum. If it is steel (hopefully) that might add a little weight, too.

 

Will you be posting here about it or maybe the build process, I know these forums are mostly for laptops but hey lots of people want to know.

I would love to go all desktop but I kinda move around a lot.

 

Yes, definitely. I could not find an 8700K for sale anywhere and the only way I could get one was to order a system from ibuypower. They are one of the few system builders I trust, and the only one I know of with reasonable pricing. I wanted to build my own with an i9 Extreme, but would have been about $1300-1800 beyond my budget by the time all was said and done.

I will be installing a separate EVGA closed loop cooler on the 1080 Ti SC (which arrived already). I wanted an open bench case, but they don't have those. Will likely buy one later on, and maybe (cash flow permitting) a second liquid cooled 1080 Ti SC in SLI and a water chiller. Probably going to do an unboxing video, a review on ibuypower, a before/after video showing the air vs water GPU results, etc. I'm still a little nervous about someone else assembling my desktop instead of doing it myself (my preference) but hey... they do thousands of them every year, so they must be doing something right.

Maybe I will start a new thread for desktop benching.

 

There are plenty of 8700k on ebay for 550-$600, hahahaaa crazy

 

There were none when I placed my order. I looked everywhere... literally. I looked long and hard because I wanted to build it myself and do everything my way. And, yeah... that's way too much for an 8700K, LOL.

Edit: I even see one on eBay now for $1,299 LOL. What kind of idiot would pay more than Intel suggested retail for an unbinned random CPU? Recommended Customer Price: $359.00 - $370.00

 

1.265v @ 5.0Ghz in BIOS boots up fine, passed CB bench and using it now. While I would never say that it's stable it certainly is a testament to how amazing this chip is in comparison. CB temps maxed at 72C on one core and pulled just 117W max and average voltage load was 1.248v measured in HWiNFO64 and CPUID.

 

Sounds perfect. Basically the same voltage and watts as 7700K at 5.0GHz in spite of having two additional cores. Can't hate that.

 

And the new Cpu HS in P870TM1 will most likely handle +-150w @ole!!! +rep @Talon for your testing

And previous test... 5.0Ghz all cores, no offset, 1.275v = 120.3w

 

Lets keep shaving shall we?

https://imgur.com/a/ZDe5t

5.0Ghz 1.250v BIOS, showing 1.232v under load.

1628CB. Just 116w. Max temp 70C.

Still registering 0 WHEA errors, WTF how low can this chip go.

I'm going to go ahead and call my 1.275 previously reported as "stable" lol. I am sitting here running windows, gaming, and doing everyday tasks on 5.0Ghz with just 1.232/1.248v running through the chip.

 

That's really awesome. I hope my chip is that good.

Are you running W10 or W7, or both? I plan to dual boot as I always do.

Can you please run a 3DMark 11 and 3DMark Vantage and see what the score looks like at 5.0GHz? If you can, please post a link to the uploaded scores.

 

Windows 10, I will run install those if I have them and run them. Now shaved down to 1.235v in BIOS. It's holding 1.232v in Windows. Lets get those downloaded and give them a run.

VID is requesting a steady 1.275v. My former chip was around 1.4v at 5.0Ghz. VID should honestly be looked at as an ASIC score almost.

 

3DM11+3DMark suite and 3DMark Vantage(included key). Pick all outdated with key while you can.

 

Yes, definitely.

3DMark 11 and 3DMark Vantage will both test the CPU much better than any of the benchmarks available in 3DMark suite, and the scores will reflect more "credit" for a stronger CPU than 3DMark Suite does.

Fire Strike is mostly a GPU benchmark. Time Spy is often unstable. Of those included in 3DMark Suite, Sky Diver is the best IMHO.

I do not recommend using the Steam versions as that's just more overhead that steals CPU clock cycles for no legitimate reason and bogs things down.

I will still set up dual boot on mine. In most benchmarks, especially 3DMark 11, 3DMark Vantage and Sky Diver, Windows 7 beats the scores on Windows 8.X and Windows 10 because Windows 7 does not impair CPU performance as much as the newer OSes do.

 

I mean you can use the key from the Steam versions and use it on the standalone versions. Of course this means you have to download from Steam and then delete it and rather download from other places and use the key. But the price diff ain't big. Depends on what deal you get.

 

Yes, you are absolutely correct. You can use the keys either way with Steam or non-Steam. That part is no problem. But, if you use the Steam installation the benchmark scores are usually lower because of extra stuff running in the background. And, you cannot use the Steam-installed benchmarks without Steam running as far as I know. I know you already know this, bro. I mention it for those that haven't stopped to consider that Steam versions will leech performance away from the benchmark and lower scores.

@Talon - be sure to disable G-Sync and V-sync in NVIDIA Control Panel and tweak the Global Profile for maximum performance on everything, or that will also lower the benchmark scores.

 

From Futuremark support...
Do the Steam keys differ from normal keys?
"No. If you purchase 3DMark, PCMark 8 or VRMark from Steam, when you install the Steam version a perfectly ordinary key is automatically added to your registry and you can view it from the user interface of the benchmark. As this is a normal key, it can also be used with stand-alone 3DMark, PCMark 8 or VRMark installers - you are not required to use the Steam version even if you buy the benchmark from Steam. The key also works just like any other 3DMark, PCMark 8 or VRMark key with the 3dmark.com online result service - if you submit at least one result with Advanced Edition, the key will be added to your 3dmark.com account, all online service features are unlocked and the key is stored under Settings on the account."

 

That is accurate, but the information Futuremark provides is incomplete and not clear and concise about what happens when you download from Steam.

I am almost positive that if you install the benchmarks using Steam, when you run them it will automatically launch Steam. Buying the keys from Steam is fine, but downloading through Steam is not the best approach. I could be wrong, but I am almost positive that I remember Steam launching automatically if you run the Steam-downloaded versions. They are also installed in the Steam library and not the default location. Same applies to Catzilla installed through Steam.

 

Yes, I tested it to confirm. I installed the Steam versions for testing. Launching the Steam version automatically starts the Steam client.

 

Big reason never buy any benchmark software from Steam!!

 

If the keys are on sale, no problem if you can get it cheaper from Steam. Just download from another place like Guru3D or TechPowerUp and use the keys from Steam to install and register outside of Steam with non-Steam installation. Works for Catzilla as well.

@Talon - be sure to set 3DMark 11 for stretched not centered. Centered will cap the framerate and lower the benchmark score. See below.

 

https://www.3dmark.com/3dm11/12458342

First run with OSD/Rivetuner Statistics. 1.250v no issues.

That fact that 5.0Ghz @ 1.200v booted into windows is jaw dropping for me. I've found rock bottom boys. 1.200v is where she crashes inside Windows with the 50x multi.

https://imgur.com/a/nPkM2

 

Test without monitoring or other OSD software. Pure 3dm11 benchmark. If physics is below 17300. Re-run with monitoring software to see if you can see throttling.
Physics is very low (Win 10), hence need more testing with 3dm11.

 

Damn 17,300? Which 8700K is doing that? It's probably windows 10 compared to windows 7. But if all I'm losing is a few physics points in a synthetic benchmark from 2011 I think I'll survive lol.

 

No, with Windoze X. You find scores here. Search on i7-8700K. Remember filter away Sli (two or more graphics). Only put single (1) Graphics who will give higher physics.

Don’t run bloat like antivirus software and similar in the background when benching.
