Intel "Coffee Lake" Builders Thread

[Ferzerp]

Amusingly, I am having to raise voltages because at a medium load, with my offset, the CPU isn't requesting enough voltage. I can run 3dmark with prime95, but not by itself at -0.11V

Just got my 8700k from B&H, along with the hgst 8tb drive. Expect my motherboadr tomorrow, case, ssd, and cooler Friday so I'll be all set. got my RAM yesterday and bought power supply a few months ago when on sale.

I'll start my build on Saturday. I have very limited experience with overclocking and testing/benchmarking. I'll post here how the build goes and would welcome suggestions on getting a little extra out of my system. I had hoped to get a new Intel Optane p900 but prices are too high, and availability low so I ordered instead a 960 pro.

I'm gonna take this 8700k out in just a little bit here and toss in the other one and see how well the 2nd one overclocks. Wish me luck guys. As I said prior I will take some pictures this time around, but don't judge to harshly lol. I had to do something REALLY silly for my setup. Well, I didn't HAVE to, but I felt I should. So....what I did was...ok well here is my logic. I am water cooled right, and in the 900D the intake fans are really far away and the radiator fans I have as exhaust fans, along with a rear 140mm exhaust fan. So my logic is that the vrm and ram etc would be getting a bit warm with not a ton of airflow directly near it. So...I took zip ties and looped them around my radiator, then made another loop of a zip tie and put it through my old scythe ultra kaze fan and pointed it towards the cpu / vrm / ram to keep things cooler. It looks pretty silly, but I think it actually will help keep temps down. Here let me get a pic so you can see what I mean lol. Just don't be to mean =P.

 

[fastamdman]

As you can see, there is NOWHERE to have a fan located near that area and the intake fans, even being high powered at 100% are like a mile away from everything else since this case is massive lol. So I figured that would be a good way to get some cooling on the parts while being water cooled. As a side note, the strix board, ram, video card are all cycling through different colors and just the nzxt logo is static currently as I am having an issue getting it to change through multiple colors with the cam software, im sure its just some bug that will get updated soon. This is the first time my OCD hasn't been triggered by all of the case lights not being the same color lol. My old setup had everything as red.

Currently testing my 2nd chip which seems to be a better overclocker. Currently running 51x with a -300 on avx. So 5.1ghz for non avx and 4.8 with avx. Voltage is a bit high, between 1.344 and 1.36, but so far it seems stable. I think I could get 50x stable without any negative on the avx side, but it would take more voltage than I want to run for 24/7 use. This chip had no problem at booting up at 5.2 or 5.3 though, it just really likes voltage. Unfortunately since I am just using the NZXT Kraken X61, I can't push things to to hard. I will say though, whether its this 2nd 8700k, the remount of my aio or the way I applied thermal compound this time, my overall temps are much lower than they were on the first chip. So I am happy about that. Seems to be a good chip but just a little on the voltage hungry side. But AVX can be difficult to get stable. I think once I delid this chip, I will have A LOT of fun with it lol. I challenge @Ferzerp to pass 20 passes of LinX 0.6.5 on his chip (With at least 2gb of ram being used).

So, has a consensus developed regarding a good AIO to use with a delidded 8700k? I’m assuming a 240 or 360 mm radiator would work. I really don’t want to do a custom loop if I can avoid it.

Well, if my arctic cooler 360 can cool a 16C/32T TR, it better be able to do 6C/12T cores

I'm going to be using a Corsair h115 which is 280mm. Ill see how it goes my cpu is stock

I'm having no issues with my nzxt kraken x61 between 5.0 and 5.1 I need a little to much voltage for 5.2 and 5.3 to be stable though. As long as you are around the 1.3x voltage range an AIO should be completely fine.

 

[Ferzerp]

As requested... Though I used IBT instead of LinX. They're both just GUIs that spawn Linpack, so they're the same exact thing. I did 4GB ram use. I just set it on no voltage offset, no AVX offset, and 5.3Ghz. It might go higher. Who knows. 81C though, that's kind of warm. Power draw was peaked below where it was on auto 5 Ghz prime95 though.

 

[ehume]

I’ve had good luck with Gigabyte in the past BUT their Aorus X370 Gaming K5 probably cost them some future sales from me. I’m leaning toward the Z370 Taichi (love my X370 Taichi), the Asrock Z370 Extreme Gaming, or the Asus Maximus Hero.

How did Gigabyte's Aorus X370 Gaming K5 probably cost them some future sales from you? What did they do wrong? This is exactly the board I was considering. What reasons do you have to lean to the Z370 Taichi? Markfw likes the Taichi as well.

Q - does the Taichi have a button on the board for start/restart? I will be building without a case and I kinda need that feature.

Stay away from the Gaming K5. The release BIOS was absolute crap and while it has probably matured into an "OK" board, it lacked overclocking features. Many of us felt they misled us. Mine is sitting in my closet with a Ryzen 1500X in it, which I'll probably sell to my brother for his GF because he doesn't care about overclocking.

Not that I'm aware of.

My X399 Taichi Threadripper motherboard has power and reset on the motherboard. No idea on the Intel ones, I could not see it in the specs.

Ok my Asrock z370 Extreme 4 arrived. The system, with a 8600k, is now up and running, but son I'm disappoint. I must be doing something wrong with the RAM or I have gotten a special treat...again.

My RAM is the G.Skill RipjawsV 16GB DDR4-3200MHz (F4-3200C15D-16GVK) and it only works at 2133, lol.

Granted it's not in the QVL list but does it really matter? I have never used a QVL RAM on my mobos and they all worked fine. Load up the XMP and you are good to go. Why is the same thing so difficult now?

When I select the XMP profile, the system gives a fail to boot error upon posting. If I set the speed to 3200 by hand, the same error appears. If I set the speed to 2666, it boots but it changes the timings to much slower ones, 16-18-18 or something. If I leave everything at auto, it boots at 2133 15-15-16-36 with 1.35V while its jedec info clearly says it should use 1.20V for this profile.



At this point, I think the motherboard isn't reading the ram correctly, but I don't understand why. Aren't these things universal? From within the BIOS however, you can clearly see the correct profiles. It's just that it doesn't know what to do with those.

The motherboard arrived with the 1.00 BIOS and I flashed the latest 1.11 one.

Any ideas?

Challenge completed!! Great job passing AVX, albeit with higher temps and I'm sure prime 95 with AVX would put you into the 90s easily. I'm surprised at that voltage though, am I reading that right. Is it a maximum of 1.4 volts on one of the cores and a general vid of a maximum of 1.386. I thought you were running a much lower voltage from your previous post but maybe I read it wrong. Regardless, that is a gorgeous chip. If I owned that I would run it at the absolute max I could achieve with a 1.35 voltage, set it and forget about it. I'm curious how high you can get that chip stable. Will it boot at 54x 55x? I think it's safe to say that is a "golden" chip. Congrats on winning the silicon lottery man!! Have you ever had an amazing chip like this before in the past? My chip will do 5 to 5.3 as well, but I can't get it both AVX stable and non AVX stable with reasonable temps on my nzxt kraken x62. I'm thinking once I delid the chip though that I will be able to. I don't think I would have a problem running 1.4 volts through the chip 24/7 lol, but I live on the dangerous side =P Congrats once again, feel free to give me a challenge that is uh....a lot more reasonable than the one I set for you =P

I would suggest updating to the latest bios if you haven't. There have been several bios updates in just the last couple of days. More and more bios updates will be coming out every week until things are the way they need to be. Once you have the latest bios installed, I would suggest manually setting the speed and timings and voltage. If that doesn't work then that is extremely unfortunate and it could possibly be faulty ram.

 

[psolord]

Thank you for your answer. Indeed I have the latest BIOS as mentioned above.

I am very puzzled as to why is there a problem. I mean wasn't the whole XMP profile put there in order to make things easy for the users? At first glance it seems to be recognized correctly but ultimately the system fails.

If the memory was faulty, wouldn't it crash at any speed?

What worries me is that in the manual's RAM setup page, they show this.



Now if I understand correctly, they suggest that when you have only two ram sticks, you should use slots DDR4_A2 and DDR4_B2 slots, right? However I have used the other two ports, A1 and B1 because I have always used those in my other systems.

Is the manual correct or is it an oversight? Using the second slots seems...wrong?

Anyone with Asrock can verify this?

They show the same for their Taichi series.



edit
PS On my old P67 they were much more communicative regarding RAM setup, not to mention the old P67 system was looking more robust in terms of ram setup. Unless they were bored to write more details regarding ram. Or there really is such a limitation for Coffeelake for whatever reason?

 

[Crono]

Follow the manual, it's correct.

 

[psolord]

wtf, motherf.....why don't I read the manuals before installing? lol

I will eat my hat if it works on A2/B2. Still sounds illogical but I will give it a go.

 

[psolord]

Ok now I have to find myself some good gravy for that hat!

Indeed at A2/B2 the RAM worked at 3200. Wtf? Why on earth A2/B2 would be the primary configuration?

Anyhoo lesson learned. Read the manual first. Asrock buyers, take note.

thanks.

ps Winrar went from 8100 to 10900. xD

 

[WhoBeDaPlaya]

Thanks Aikouka. Any concerns with it being 8 years old? I've never had one so long, in the past I replaced PSU's because I needed more power. Power requirements have leveled off.

Here's an interesting datapoint. HardOCP revisited a 7yo SilverStone Olympia 1kW PSU :
https://www.hardocp.com/article/2015/03/09/silverstone_olympia_1000w_power_supply_7_year_redux/6

That said, I still have a bunch of similarly old BFG PSUs running many rigs (3x modded EX-1000s, few ES-800s)

Gonna be honest with you, I thought the exact same thing when I built my 8700k system. I just for the hell of it, was going through the manual, while taking a bit of a break and noticed that ram should be in a2 and b2 if it's just dual channel with 2 sticks. I figured it would have been a1 and b1 but I said oh well and went along with it. I didn't think it actually mattered though, I prefer the looks of a1 and b1 versus a2 and b2, but whatever works, works. Glad you got it figured out though man. Now get to overclocking

 

[coercitiv]

Why on earth A2/B2 would be the primary configuration?

Maybe because it offers the best chance of clearance when using low profile coolers and only 2 memory DIMMs?

Thanks man. It works like a champ now.

Indeed I will.

 

[psolord]

That would be very logical, if it would be in the context of a suggestion and not a forced limitation. I mean why not make it work in A1/B1 if the cpu cooler allows the user to do so? Like mine did.

Also since these things are meant for DIYers, why not make it more clear for end users that now A2/B2 is the thing? If I hadn't looked in the manual, I would have been troubleshooting this for I don't know how long.

Even so, in the manual there should be a warning that if you place RAM at A1/B1 it would not work correctly. A very logical notice for people carrying the A1/B1 knowledge with them.

I have always put my RAM on A1/B1 god damn it. What was more logical?
