Intel "Coffee Lake" Builders Thread

[psolord]

Speaking of AVX offsets, I was testing Grand Theft Auto IV yesterday, with the built in 4.8Ghz profile of the motherboard and I saw that the cpu was running at 4.3Ghz in MSI Afterburner. I thought wtf and it was the AVX offset.

I then created my own profile without AVX offset and the cpu was running at the proper speed.

I guess this is a good way to see if games use AVX extentions, but I thought the AVX offset was meant for AVX2? Is GTA IV using any AVX instructions, let alone AVX2?

Need a little advice here; speccing a gaming PC for someone on a budget and I can't decide between the 8350K and 8400. Which would you pick? He won't be OC'ing.

8400

 

[fastamdman]

If he won't be overclocking I would suggest the 8400. Don't get the K series if you aren't overclocking.

OK, got all mty stuff now except for the EK Vardar 140mm black fans that I will use on my radiator. I'll have them next week so I'll either take it slow putting this together or probably just swap out the stock Corsaifr fans when they arrive.

I had hoped to use on new Optane ssd as the system drive but the availability and pricing was not good so I went with the 960 Pro.
The RAM is the TridentZ series 16gb ddr4 3600 F4-3600C16D-16GTZ which, I think, should run real well. I'm excited as I am upgrading most everything with quality parts.

I'm not real familliar with overclocking I'll be using the h 115 cooler I'll maybe ask for advice when I get this running.
Also, not sure about this. The cooler will fit either in front, or up top. I want to run it in the front which should be quieter but I wonder if anyone ever installed the two fans on the outside pulling air out the front? I could put one of the fractal fans, or a Akasa Apache I have, on the bottom as an intake. Or alternately, fans on the inside of the radiator pulling air in. with exhaust in the stock position on the rear of the case.
Here's my stuff:

Everything put together and an easy stress test pass by setting the multipler at 48 and load level calibration at "2" on my Asrock Extreme4 with no other changes made besides enabling the XMP profile on the RAM which again was a matter of ticking one button. This stuff is too easy these days. Will push for higher tomorrow. Voltages are 1.30 or so at 4800 with light load and around 1.25 with max load. Have no idea if I could go with lower volts, I'll raise the multiplier later to 49 and give it another run tomorrow. :\

https://valid.x86.fr/39p37p

Temps are around 70 degrees C without delidding, but keep in mind it's only 60 degrees F in my house right now. Using a NH-D15.

Given I was running a 2600K @ 4.5, I'm happy with the 8700K @ 4.8 for 24/7 use, much less 4.9 or 5.0.

Ordered a Raijintek Metis Plus (blue) ITX case. I think that will finish off my build. I was really tempted to order Corsair LL fans for it because of recent reviews of the performance and purty RGB, but that $120 price tag for a 3 pack with the controller dissuaded me. If they were even just $20 less I probably would have pulled the trigger. I have too many other 120mm fans sitting here, anyway, I'll just use two of those.

Wow 18506 overall score? The only time I got a higher score was in 3dmark06. xD

Still my OC GTX 1070 is quite close to your 1070 Ti

Also now that I have a 8600k I will OC it to 5Ghz and I will show you!

j/k enjoy it mate

Well, still tweaking the overclock, so it's getting 18,755 overall now. Can't match an overclocked 1080, but it's in the mix versus stock.

8600K is a very nice gaming processor overclocked, so I hope you do show me, haha.

Good job.

Have you tried saving some profiles on your Asrock Extreme 4 z370 and then loading them?

Every time I try to load a profile, the system freezes. Been doing it since the 1.11. Today the 1.20 came out and it still does the same. :S

I can throw that onto my agenda tomorrow and let you know the result.

I actually think Divinity Original Sin 2 may use some form of avx also. Perhaps these instructions are more common than we think? (great game by the way)

Once you remove the IHS from the processor you are going to want to clean off the die. It will have a bunch of thermal paste on it. Gently, very very gently, clean off the die. THEN after the die is clean, simply remove all of the black glue that was holding the IHS to the processor. Once all of the glue is off, apply your choice of thermal paste to the die itself. DO NOT FORGET TO HAVE THERMAL PASTE ON THE DIE. Then, gently put the IHS back on the cpu. Install the cpu into your motherboard. Then put thermal compound onto the IHS and install your water block or cpu cooler of choice Hope this helps. For best results, please use something like liquid metal or thermal grizzly on the die itself.

Thanks, I can't wait to try this. I have liquid metal on order.

The Taichi was my first choice but unavailable when I ordered. I picked up the Gaming K6 and am very happy. You can't go wrong with either mobo.

I like the Z370 Taichi so far. No issues, everything worked instantly out of the box. XMP profile loaded with zero issues, even though it is an aggressive bin (3600 CL15). I'll have further impressions after I use it daily for a week or so (and test OC limits).

My case is a Corsair Air 540, with 6x Scythe Gentle Typhoon AP14 fans. They run at around 1200 RPMs on a fan controller and give good airflow, and I want good airflow over all my components (esp. motherboard VRMs) for when I start testing OC capability. It's my baseline case/fan setup for figuring out OC limits on air. If I'm limited by air cooling dissipation rather than voltage, I'll move to water. Had my Threadripper setup in that case, but moving it to a different one as a dedicated workstation. My Coffee Lake is my "play" box so it will get abused

If I am reading correctly you have a Fatal1ty Z370 Gaming K6. I have read that it has cool VRM's even while overclocking. Also, it looks like it has a button for start/restart on the board. You have been hands-on with the board. Both cases true?

Yes. It seems very solid. I haven't pushed my 8700k much since I'm on air but it was extremely easy to hit a stable all core 4.7ghz (under Prime95 29.3 avx), 46 cache, 3600mhz 16-16-16-36 (haven't tried to tighten timings yet). The K6 had all all the bells and whistles I wanted and I'm very happy with it.

I had the Asrock Z170 Professional i7 Gaming mobo with my 6700k and was very happy with it as well. My only complaint with that mobo is memory support was weak at first, so far the Z370 seems to have decent memory support with the two sets I've used (3333 and 3600).

Just curious what voltage you needed for 4.7ghz on all cores and 46x on cache. I haven't tested speeds below roughly 5ghz or 5ghz with avx much if any so I am curious I'm sure I could drop my voltage a decent chunk and still be stable at those speeds. Let me know, thanks

What do you guys think about this RAM for an Asrock Z370 with an i7-8700k? It's on sale and I'm considering 1 or 2 kits for my build:

https://www.newegg.com/Product/Product.aspx?Item=N82E16820232298&ignorebbr=1

DDR4 3000 (PC4 24000)

• Timing 15-16-16-35

• CAS Latency 15

• Voltage 1.35V

They also have the Trident RGB on sale:
https://www.newegg.com/Product/Product.aspx?Item=N82E16820232476&ignorebbr=1

DDR4 3200 (PC4 25600)

• Timing 16-18-18-38

• CAS Latency 16

• Voltage 1.35V

I'm thinking the first RAM is faster. I've reviewed some 8700K RAM gaming benchmarks and even going up to 4000 only results in 1 or 2 FPS difference, but those benches were all at 1080p. Going up to 3200 at CL15 or better is nearly another $100 for a 16 GB kit and I don't think the performance difference is worth it when I can apply that money towards a better GPU or monitor. Thoughts? If I buy either kit, do you guys think I should stick with 16 GB now and just wait for RAM prices to drop before I get another 16 GB? I'm afraid $123-$160 might be the best price we see for 16 GB of DDR4-3000 for quite some time.

Your RAM all come with tall heatsinks. We had heatsinks that tall when we has1.65v RAM. Now we have 1.2-1.35v RAM, so we can use low profile RAM. In fact, for my 1.35v DDR3 I got ultra-low profile RAM, where it was no taller then the RAM clips. For DDR4 RAM the ULP was now available so I got Corsair's LPX sticks.

Now, if you are using an AIO for CPU cooling, it makes no difference how tall your RAM is. But if you use a heatsink, tall RAM might get in the way of your fan. Don't pay extra for coxcombs.

I'm going to be using an AIO. I was originally going to scavenge 16 GB of RAM from my Ryzen 1700x system and give it 8 GB of RAM instead, but the price I see on this RAM is acceptable enough to me that I can leave the 1700x with its 16 GB of RAM. I'm thinking of the two, the Trident might have the smaller profile but I really don't want to pay $300 for 32 GB of RAM when I can pay about $245 instead when both are roughly the same speed after you take into account CAS latency. Plus, if I decide to only go with 16, I'd hate to stick 2 RGB sticks in there and then later decide to go another route for the other 16 GB.

EDIT: Just found CL14 DDR4-3200 RAM at a decent price:

https://www.newegg.com/Product/Prod...232217&cm_re=ddr4_3200-_-20-232-217-_-Product

Looks like they use Samsung B-die as well. Buy two kits?

My personal opinion used to always be "go with the fastest ram you can afford". Whether faster meant highest frequency or lowest timings or a mixture of both, is up to the buyer. However, I have to say man....I was in a pinch and the only place I could go to get ram RIGHT NOW type of deal, was a micro center. They didn't have very many different types in stock, I mis read a post somewhere and ended up grabbing the trident z 3200mhz cl16 2x8gb set. At first I was a little disappointed, I was like damn I didn't buy samsung B die, it's to high of a cas latency, i'm irritated. But, I don't know what it is....the more and more I look into my case, which is on my desk. I absolutely LOVE the RGB ram. I'm not a big rgb guy either, but it looks so damn good in my case that I am actually happier that I went with trident z over anything else. Yes, there is faster ram, yes there is cheaper ram, but there aren't a whole lot of sticks of ram that look as sexy as these. My 2 cents is if you care about RGB AT ALL, grab the trident z sticks. If you don't think you will ever care if your ram is rgb, then grab the ripjaws you last posted. That's just my opinion though, I'm sure everyone else will say to go with the fastest ram possible and that rgb doesn't matter and I am crazy haha. But it looks sweet man....I'm staring at it as I right this, watching it change colors with my motherboard and video card and AIO cooler. It just fits perfectly!
