Intel "Coffee Lake" Builders Thread

[TheF34RChannel]

Eh, everything I've read states that I should simply set the BIOS to use XMP, and it will work. Hardware Canucks reviewed a different version of the memory, and they stated "This memory kit comes in clocked at DDR4-4000 19-23-23-45 with a 2T command rate. It requires 1.35V - up from the 1.20V default - which is identical to other enthusiast-oriented memory kits, and it's impressively low given the very high frequency. This is all programmed into the single XMP 2.0 Profile, so enabling these settings is as simple as toggling the XMP option in your motherboard's BIOS." When my hard drive test is done, I'll pull the memory and test it in another computer.

You should read elsewhere then; you're proving my case for me the chances of high frequency being XMP able are incredibly small. No need to test it elsewhere, your memory is fine. Just needs manual tweaking. Combined with a fresh install I'm confident you get things sorted - if your IMC can handle the frequency; if not you may find yourself needing to lower it manually.

If you're lucky it will work. Just make sure the dimm voltage is at 1.35. I think some boards will put the VCCIO and VCCSA too high when they're on auto so after you get things working you should drop them as low as you can manually.

Placed a preorder at B&H for an 8700K. I figure it will be awhile and I can cancel if I change my mind or find it elsewhere. I'm thinking about the Asrock Taichi Z370 - any thoughts?

I looked at a few of the Z370 board offerings. The Z370 Taichi looks like a good board. Strong VRMs etc. I know I like my X370 Taichi on the AMD side, and it would not surprise me at all of the Z370 Taichi also proved to be a fine product.

If you are going to get more RAM, it might be better to buy sooner than later since DRAM manufacturers are already projecting shortfalls in 2018 slightly worse than those in 2017. More supply, but even more projected demand.

decided to build a rig after all and give my 2600K built in early 2011 to my nephew as his computer crapped out and I watched him get annoyed with the slowness of it. I could also keep the 2600K and give him my bedroom build 6600K.. haven't decided yet.

Here's the stuff I ordered minus what I'm salvaging.

It took me awhile to decide on the case.. it had to take at least three 3.5 inch drives while supporting a long video card, or 6 without, have at least one 5.25 inch drive enclosure, be wide enough for large heatsinks and cable management, have front intake vents, and most importantly, just look sexy. For some reason the military ammo can look just sucked me in, aside from it meeting all the other requirements and also having handles.

I'm also gonna throw one of these in there after carefully painting the outside a matching green. I just forgot to add it to the cart.

G.SKILL RAM running at 3200 with 14-14-14-34 seemed to be the sweet spot for price to performance so I went with that. The Asrock board had a level of attention to detail that attracted me towards it over the other brands combined with the positive reviews. Throw in some negative experiences I had with a gigabyte board with my bedroom build and I thought I'd give em a try.

That just doesn't make sense though. How is it legal to even advertise these components at these speeds if they don't work at them?

I tossed the RAM into my other Coffee Lake machine to see if it would post. To be fair, this one is only running an i3-8100, so it's not really as close as the one running an i7-8700k. However, both motherboards state that they support up to (and in one case, beyond) DDR4-4000. My ASUS ROG Strix Z370-H Gaming was able to set the memory to XMP, but after saving the changes, it refused to boot. Amusingly enough, I checked the reviews for that memory that I bought, and now there's a review with one guy complaining that he couldn't hit DDR4-4000 either.

I think I'm just going to return it and go with some DDR4-3200. It ought to be somewhat similar since I'll go from 19 to 14 CAS latency.

Oh, and I don't know if I'm just picky about disliking "Gamerfied" software, but ASRock's BIOS is so ugly compared to ASUS's. On the ASUS board, it is so much easier to find things, but the ASRock board is just an eyesore to even look at. Why don't people just make nice, clean UIs?

Be Quiet! Dark Rock TF came in. I just finished removing the stock cooler and installing the Be Quiet! HSF with some fresh Noctua NT-H1 thermal paste on the 8700.

Idle temp is now down to 26C, and the temp running AIDA64 system stability test (stress: CPU, FPU, cache, system memory) for a few minutes has gone down from throttling (~100C) to topping out at 76C (highest temp of any core peaked at 82C). 100% utilization of all 6 cores at 4.3GHz throughout. Much better results than the stock cooler (no surprise there) with virtually silent fans, even up close in open-air.

Price was steep for an air cooler at $80 on Amazon (resellers on Newegg want even more at $120) which is encroaching on midrange AIO liquid coolers. It's worth it for me for the silence, and the fact that this build is going in a custom 3D printed case (not finished yet) that won't have room for an AIO unit.

I don't think I would recommend the Dark Rock TF for anyone using this motherboard (ASRock Z370M-ITX/ac) as it doesn't quite fit properly. The heatpipes are pressing against a heatsink on the motherboard (VRM?) on one side - enough to bend it - and touching the first low-profile stick of RAM on the other side. It would likely be a much better fit on a micro ATX motherboard, however. This video was really helpful, by the way, as there were one or two confusing steps poorly outlined in the installation guide. Otherwise it was about the same as any large single or dual tower heatsink installation, requiring the use of a backplate.

Also updated Windows with the Fall Creator's Update (aka version 1709) and everything seems to be working okay. Haven't tested to see if it affects gaming, as I still need to get a GPU. I'm waiting for the 1070 Ti, though I may end up getting a mini regular 1070 or 1060 instead.

That cooler does look like the second coming...

 

[TheF34RChannel]

I saw the Hero provides the option to show CPU temp on the QLED instead of post codes in Windows etc., and thought that was a neat feature. Comparing it with sophisticated monitoring software was curious: the QLED is off negatively by 10+ Celcius (equals pointless). Nowhere in my testing did I find a temp close to the software readout temp, so feature disabled again.

Anyone got any experience/thoughts on the MSI Intel Z370 TOMAHAWK?

I am looking to pair it with the 8700k with some mild OC'ing. Plus, I want one usb c type connector (future proof a bit) and have 4 pin system fan connectors to set variable speeds on my system fans.

That thing is wider than the board; I love it

Just a note, you can set variable speeds with both 3 pin and 4 pin fans. 3 pin fans can be controlled with the DC voltage. 4 pin fans can be controlled via PWM. You can set the fan type in BIOS, and many BIOSes detect the fan type automatically. PWM is more precise, but both control types work fine.

I just ordered my 8600k and an Asrock z370 Extreme 4. I already have a pair of G.Skill RipjawsV 16GB DDR4-3200MHz (F4-3200C15D-16GVK), to go with them. Leftovers from my Ryzen upgrade plan, that never got to be fulfilled, due to the memory compatibility debacle that plagued the Ryzens at first. Then the news about Coffeelake came and the rest is history. Oh well, next time AMD. I still love you.

My 2500k, mobo and RAM, will go to my secondary system and will replace my i7 860, which in turn will be re-purposed by a friend. Who knows maybe I'll throw it in a small case for some tertiary system benchmarking fun.

For my workloads (gaming, game benchmarking, browsing and the odd encoding) it fills the bill just fine. I saw no reason to go for the 8700k, which costs 120 euros more. Good money that will be invested on the 2070 later. Also lower temps and zero gaming loss. For now at least, but hey, these are six of the best cpu cores out there. If the 2500k served me honorably for six years, the 8600k will do an even better job I believe, also helped by the good enough RAM it will be running with.

Oh man, Hardware.fr says that I am looking at 115% performance increase from the 2500k to the 8600k for apps and 60% for gaming. Maybe not with the 1070 but things will be different later. The fact alone that I will get rid of even the few dips I get in some games with the 2500k, is good enough for now. I mean I don't even remember when was the last time I did such an upgrade. Maybe only when I went from the E6600 to the Q6600. My upgrades are fuzzy before that.

Ooh ooh excited. Grow up man!

I just plugged in the PWM fans of the AIO and left it as is (full speed when left alone I presume?).

If Dark Rock TF is able to cool down 8700 to only 76 degrees under load, then it really runs hot. This Cooler with dual fan config is rated at 220W TDP, and is one of best performers in the business, considering its form factor, and actually pretty compact size, with just 135 mm height.

Im baffled by your temps. Either something is wrong, or Coffee Lake really runs hot.

Perhaps he has it set to silent mode in BIOS?

Well, you should at least go into the BIOS and see what it's set to.

It's set to auto or whatever the default setting is for this motherboard, but I have to check and try changing it if it's set to a lower RPM mode, and see what the CPU voltage is at.

But given coercitiv has his 8700 hitting 85C using Cinebench with a Noctua NH D14, I think Coffee Lake may run a little hot, even on a non-K 8700 when it's running all 6 cores at 4.3GHz.

I meant to do that originally but it slipped my mind when I booted up and just went aw wow

 

[Justinbaileyman]

Crono, you should rotate your cooler if you can like a quarter turn cause by the looks of the picture you posted the heat pipes are pushing on the VRM heatsink slightly tilting it off the chips just sever so slightly.Not a huge issue but could be a problem down the road.

Did a CB run (that was the thing the other member tried right?) with mine, stock clocks so 6x4.3, ~1.21v (auto; too much) highest temp was 67C.

Just got my i7-8700k from Newegg.. No cooler?? Ok well what should I do about cooling this thing? Pretty sure I am not putting my Phantek pc14 on this sucker.To scared the weight will crack the pcb of the cpu. Should I go water cooling this time around? Is water cooling gonna be a must anyways? Looking at the Corsair H115i v2., is this any good or will I need something bigger like a 360mm or 420mm rad?

The H115i should be plenty. If you want to lower the temps even further, add two more fans and go push/pull. If it can cool my 7820x, it should be plenty for the 8700k. The stock fans are kind of loud at full speed, but that seems to be the case with all the AIOs. If you want to go super quite, there are some good fans out there.
