Intel "Coffee Lake" Builders Thread

[Markfw]

I only ran Prime Small fft's for a couple hours and CPUZ Stress Test for a couple of hours. Also been running Handbrake Non stop since last night. The only thing that makes my CPU Spike in temps is Prime. Is there anything else I should try running?? I guess I should note I do have my fans running full blast in my case and on my 212 Evo.

But my point is that on a benchmark, if its not throttling, and you score is reasonable compared to norms, then you KNOW its not throttling. Not sure the best benchmark for that, as CB15 doesn't last long enough to heat it up. Again, I could be wrong on this, but those temps seem way too low.

 

[IEC]

I don't want to be a wet blanket, but have you run a benchmark to be sure its not throttling ? 42c full load sounds way too cool with a 212 EVO@100% load. I can't even get that with a stock 6700k and a 212 EVO

Or his ambient is like 10°C. That number does sound awfully low for a middling air cooler.

The other possibility is he has multi-core enhancement off, which means he's running a lower all core turbo (and thus, lower voltage = less heat) versus boards that default to MCE being on.

And/or a combination of winning the silicon lottery.

But there's no way to tell without additional information. It's why I always include my ambient temps (usually 25°C) with any temp reading along with case/fan/rad setup so people can compare apples to apples (or at least estimate).

The Handbrake test in this forum with HWInfo/HWMonitor and CPU-Z showing temps, utilization, voltage, and clock speeds of cores would be good way to know. Screencap midway or near end plus encode time from log should give good idea if it's throttling, since there's comparative data.

Just wanted to jump in and say hi. I was lucky enough to grab an 8700k from newegg and I might be buying a 2nd one tomorrow from a local youtuber that I know. I'm currently on the z97 platform and was wondering what ram I should go with for coffee lake. I primarily game, but I also do video encoding and streaming. I don't really care about RGB much. I've never had a DDR4 platform so I don't know if I should look for faster mhz or lower cas latency. Let me know your thoughts. The board I am picking up tomorrow is the Asus Strix Z370-E Gaming if that matters at all

I'm not an expert, but all the info I've seen seems to indicate dual channel CAS 14 DDR4-3200 or CAS 16 DDR4-3466 (or higher speed, which usually comes at higher price unfortunately) that can be run at tighter timings (CAS 14) is your best bet for performance. Coffee Lake doesn't seem to benefit from higher speed as much as Ryzen, but latency does make more of a difference. You can even drop down to 2666 and not see much of a loss in performance in games versus higher speed RAM as long as it's still low latency, but I'd shoot for 3200 as long as there isn't a massive price difference.

I can't seem to find the QVL memory list for that motherboard, but I'd get pick whichever dual channel kit that's validated, meets the above, and is priced the least (provided there aren't any other issues that pop up in reviews). G.skill TridentZ/Flare X/Ripjaws fits the bill usually, though I wouldn't hesitate to pick Team Dark Pro if it's validated.

I'm using Corsair Vengeance LPX RAM happily with (literally) odd timings, but I needed low-profile RAM.

 

[fastamdman]

Ya, my issue is they are all just about the same price. The difference between them is only a few dollars so I can't make up my mind lol. Unless I jump up to like 3600+ speeds at CL16 (which I don't know if it will run CL14 or not) then I get around 225 zone, when most of the kits are in the 175 area. Just wish I had a better idea what to get for the best bang for my buck. Thanks for the help and if anyone else can chime please feel free

 

[Ferzerp]

Well. So far my leak test is going well. I had a reservoir port leak initially. It was in a port I couldn’t get to but I managed to eventually shift things around and get it unscrewed. Oddly, on a lark, I added a second o-ring (which I’ve always heard is a big no no in general, not related to water cooling) which seems to have sealed properly. Normally I’d never do such a thing but this is an non-pressurized port that was leaking. I could have just swapped it, but it was the same size as the old o-ring which felt like was allowing the plug to bottom out on threads anyway. Since I was a little desperate with my finger keeping all the water from leaking out, I figured it was worth a shot. Hopefully it holds. Now I must decide if I am willing to let it run over night while I sleep and can’t monitor it.

Amusingly, I was concerned about my tube connections, but all those seem to be holding just fine. EK must make good fittings.

Once the leak test satisfies me, I’ll add the colorant/biocide and then install my PSU and (hopefully) be up and running.

 

[VirtualLarry]

Selling my CFL i3-8100 ITX rig, check FS/FT forum.

Was vaguely thinking of using it for a powerful quad-core pfSense rig, for my gigabit internet connection, but it looks like I might be cancelling that altogether, and it's pure overkill for my HTPC duties (which are currently provided by a J1900 quad-core Atom Brix unit that is basically silent).

You should aim for RAM with Samsung B-Die chips, their only downside is price, but they run with higher frequencies and lower latency than the rest. They also scale better with voltage.

Rule of thumb to easily spot these chips is they're the only ones capable of 3200Mhz CL14. Chips from other vendors can only do 3200 C16. As you go higher than this in frequency there's a very good chance the chips are B-Die too as long as we're talking about 8-16GB DIMMs. Corsair and Crucial have 3466Mhz CL16 offerings with Samsung chips inside, afaik all G.SKILL sticks above 3200 are B-Die as well. Nevertheless, check before buying, people made lists like this one and reviewers also check and mention chip makers.

Personally I couldn't get hold of some of the higher speed Samsung based dimms in my country, so I decided to make a few switches between my systems and am currently running a G.Skill 3200 C16 overclocked to 3466 C16. The kit is using Hynix chips and can easily be stabilized at 3466, but jumping to 3600 is problematic, and anything above that is probably impossible.

 

[Ferzerp]

I use an i5-3450 for pfsense on a gbit connection and it’s way more than 20x what is needed so yeah, that’s overkill.

Now that I was able to procure my processor, the rest of my build is beginning to take shape. I will be going with:

8700k
Gigabyte Z370 Gaming 5
G.Skill TridentZ RGB DDR4 3200 (F4-3200C14D-16GTZR)
Samsung 960 EVO M.2 500GB
ASUS GTX 1080 ROG STRIX

I will be re-using :

Cooler Master 212
Samsung 240 PRO 256gb/Seagate 2tb
Corsair HX650

And I am considering upgrading from my 1080p 24in Dell, to a Dell S2716DG - 27 inch 1440p 144hz with G-Sync. Newegg has it for 718 but it's only 530 on Amazon.

I will be getting a 6-core Coffee Lake and I have been contemplating the Gigabyte Z370 Gaming 5 MB since the gaming 7 has a fan and I test heatsinks. Please report on your build. I am interested in whether the Gaming 5 has a fan (the pictures are not dispositive). Also, I'd be interested to know if you are thermal bound. The 212 is a cheap hetsink, but it has only four heatpipes IIRC. I'd like to know if a 2121 is enopughor if a D15 would be needed. Finally, how tall is the TridentZ. I can't find a number.

 

[Ferzerp]

Due to an amusing oversight on my part I have 3 push fans and 1 pull fan on my radiator due to a lack of tubing planning. Still, it is so oversized it isn’t going to matter.

 

[Ferzerp]

Default settings, linpack (via IBT) very high never goes over 49C on any core.

Some of the variation in time is due to it installing drivers on me while the tests were running, as well as my using of the PC for other things at the same time.

Based on the temperatures, this is how I am pretty sure the cores are numbered, but I could be wrong. 1 and 5 are the coolest temps with maximums 4-5C below the others. It could be the other way around and the memory interface is acting like a heat sink though.

49c on full load? What cooler?

 

[Ferzerp]

EK Supremacy EVO waterblock, EK-D5 PWM pump, 560mm radiator with some of the "high speed" bequiet fans. The CPU was delidded, under IHS TIM replaced with CLU, the IHS lapped, and CLU used under the water block.

GPU with Unigine Superposition only gets up to 32C. I used CLP instead of CLU here because I ran out. Talk about paranoia though, I was so sure I'd used too much and was going to short out my GPU.

Wow if after all that it's running on 49c then my temps are definitely fine on a stock 8700k and 212

 

[Ferzerp]

Keep in mind that that is also with an AVX workload. I've OC'ed it to 5Ghz now (well, at the moment I'm just doing the automatic stuff testing), and doing non-avx stress testinng (prime95 26.6) The warmest core is only 62C. AVX loads get it in the 70s. I could lower temps by using manual settings I'm sure, but as of right now, I'm ok with the auto settings since temps are fine.

That's an awesome result you got there, buddy! Great stuff!!

 

[Ferzerp]

I ended up dropping fan speeds trading temp for quieter operation.

edit: further testing has shown that the noise profile of this pump is odd. It makes more noise around 40-60%. I can't hear it below, and I can't hear it above, so... I've undone the trade off, and am just keeping it running around 80% all the time (and never below 60%). I think it was causing a slight resonation around that speed I could hear.

Very nice! And similarly, I got shipment notice the other day from B&H that my 8700k will arrive Wednesday, so I've been ordering parts and my build is set other than I'm going to wait till I can take a look at how I configure the drives in my r5 case. I'm probably going to use a Corsair h115 280 cooler just want to confirm the fit.

So it's going to be
Fractal Design Define R5 Blackout edition
Corsair RM650i power supply
Intel 8700k cpu
Asus Mazimus X Hero motherboard
G.Skill TridentZ DDR4 3600 16 gb
Intel Optne 280gb system drive
HGST 8tb 7200rpm hard drive
Corsair h115 280mm cooler

I'll be putting this together mostly next Saturday. the ssd is supposed to be avail on Wednesday. Should be a nice upgrade

You will love that R5. The pull-out bottom filter alone is wonderful. The two front fans are nice, but I have replaced mine with a pair of Noctua NF-A14 ULN's. Be sure to measure and report the height of your TridentZ sticks.

Last night I was able to get my hands on another 8700k. So now I have one in my hands, one coming brand new from newegg on tuesday and I picked up the strix z370-E gaming motherboard for a really good price brand new sealed in box. I over paid a bit on my ddr4 3200mzh cl16 trident gskill ram, BUT they are samsung B die chips, so I should be able to overclock them fairly well and get the CL down to 14, or up the mhz a decent chunk to make up for it. Regardless I am going to be starting my build tonight. I will update with results.

Part list.
8700k (got from a youtuber) 2nd 8700k from newegg arriving this tuesday.
Asus Strix z370-E Gaming
G.Skill TridentZ 3200mhz CL16 DDR4 Ram 2x8gb 16gb Total.
Corsair Obsidian 900D case
Gigabyte GTX 1080
Samsung 512gb 850 pro
Crucial 256gb SSD
Western Digital HDD
NZXT X61 Kraken AIO
Corsair cx750 power supply
12 case fans in total, push/pull on radiator, tons of airflow being moved through this case lol.
Last but not least is my trusty fan controller

Peripherals include
Asus 144hz monitor 1080p (Upgrading this soon)
Razer Chroma V2 keyboard
Logitech G502
Steelseries Arctis 5 headset
Logitech z906 5.1 surround sound speakers
Logitech C920 Webcam
QCK+ Mouse pad

Should be a really fun build, I'm excited to see which of these 2 8700k's will overclock better, fingers are crossed on silicon lottery lol.

Another nice system! Paper launch my a**

Oh and I decided to go ahead and orderthe Corsair h115i cooler. It will fit either up front or on top of the Fractal case so I'll make it work. Also ordered 2 EK Vardar 140 EVO black fans for it as I remember how loud the corsair fan was on my h60.
The EK site was the only place I could find to order them and its in Slovenia They claim to ship from there but they are giving me a delivery date of Nov 3rd, so if anyone is interested in these excellent fans you can get them quickly.
