Intel Skylake / Kaby Lake

[Deders]

I have not, but wouldn't it be strange that voltages would need to be bumped to get stable operation at stock speeds?

Regarding latencymon it's showing some really bad numbers on my system. Maybe I should start a new thread about this, but could you give me a few quick pointers on how to diagnose what it reports?

Just out of interest are your memory sticks on your mobo's compatibility list? I know it's not the ideal situation but I expect vendors will cite this when responding to people with these problems. Asus did when I was asking about a bios fix for the 950 pro, even though it would most likely be the most used NVMe drive for this generation.

You have to remember that we are dealing with a lot of new technologies at once. Skylake CPU's, Z170 mobo's, DDR4 Ram (which is tuned differently to X99 compatible ram) Windows 10 (and all the fresh drivers that go with it) and in my case NVMe. There is a hell of a lot that can go wrong.

As for latency issues, I initially had problems with a windows system file that was related to networking. Re-installing my WiFi drivers resolved this. Apparently this is quite a common issue for users who have looked this much in depth to the inner workings.

The only high latency readings I get now are Nvidia and DirectX related but they don't seem to be causing me any issues whilst gaming or on the desktop.

Yeah they are on the list as supported. Gigabyte support is absolutely useless by the way, they have no clue what they are doing and apparently have no contact with the engineering dept.

I do understand, that's why I've been trying to be patient. I've been dealing with this since I built the system in Sept though, so my patience is starting to wear thin. But I'm willing to keep working at it. I am surprised no one here has this problem, though I'm happy you don't, as it's highly frustrating

Don't have a WiFi card in this system, just Intel on-board NIC.

Yeah that's exactly what I'm seeing, so I guess it's nothing to worry about.

Same for Asus (UK). It seems they try to avoid reporting the issues to the next level although to their credit they did with my NVMe issue.

I've had discussions with them at times where they were denying they had fuses on their GPU's even though I sent them links to their own website where they advertise the fact that they do.

Yeah it's frustrating. I've only managed to have mine completely stable for about a month or so. Even now I have minor issues with things like Intel display drivers blocking HD audio codecs from Nvidia outputs.

I've seen a few people over at Overclock.net with similar issues and thankfully they have people from Asus who have actually worked on designing and creating the boards themselves. (although they won't answer to anyone from outside of the U.S.). Like I mentioned before these issues do tend to get resolved with a bit of a voltage boost.

It could also relate to NIC's but if the particular .sys file isn't popping up I expect you have no problems there. Intel network drivers tend to be pretty good, but the way Windows 10 handles drivers if it automatically installs them itself, (for instance when upgrading the OS with the big November update) seems to cause issues.

Yeah that's exactly what I'm seeing, so I guess it's nothing to worry about.

I'd be inclined to think so. I wouldn't spend countless hours primarily chasing this. With any luck Nvidia will be aware of the issue but I guess it can't hurt to give them a nudge in Driver Feedback. There's a small chance it could be causing issues due to the different hardware combinations used but I'd try and rule out memory issue first.

ASRock will soon let you overclock Skylake Xeon CPUs on their motherboards

www.techspot.com/news/63335-intel-skylake-xeon-overclocking-asrock.html

Adding to this news, if ASRock prices these new MBs right, the fun of Xeon E3 overclocking is back.

3.4GHz 4C/8T Xeon E3-1230 V5 costs $275, a lot less than Core i7-6700K right now ($420) and not much more than Core i5-6600K ($270) (Newegg prices). Cheaper way to get into 8-thread Skylake fun.

 

[aigomorla]

ASrock needs to DROP the entire Fata1ty line.
Personally i wouldnt touch anything branded by his name as they all just suck period.
He isnt a hardware engineer like kingp1n or Shimano.

I personally would rather drop his name and the royalties paid to use his name, and apply that savings on the user for a cheaper price on the product.

I'm surprised no one here has yet talked about the issues people are facing with their new Skylake-S builds (might not be limited to S, but those are the ones people are checking in with so far).

I, and many others who've recently built 6700K/6600K (and non K as well) systems have been experiencing this strange complete system freeze when idle. When it happens, the only resolution is to hard power off the machine, resetting does not work. It can happen anywhere from a few minutes after leaving the computer, to several days. There's a long thread [0] over at Tom's that I've been participating in over the last couple months, but no one's been able to get to the bottom of it. This post in particular [1] sums it up pretty well.

I'm having the issue as well, it freezes for me about once per week on average, sometimes it goes longer, other times it'll freeze two days in a row. I've RMA'ed the motherboard, changed PSU, changed RAM, tried default 2133MHz for RAM, latest BIOS (even beta ones), pretty much everything you could think of. Nothing makes any difference whatsoever.

It's seemingly affecting builds using all manufacturers of motherboards, as well as all RAM manufacturers, so all signs are pointing to either a chipset problem or Skylake uArch problem. Some have even replaced their CPU's only to have the problem show up again.

In addition to these freezes, the guys over at the Prime95 forums are tracking a bug with AVX that causes the workers to fail with a hardware error [2]. They have instructions on how to reproduce if you want to try. I've been able to repro the hardware error myself.

The Prime95 issue and freezing issue are probably unrelated, but who knows, they very well could be. In any case, there seem to be some real unsettling issues with this new platform. Hopefully they can be resolved by BIOS/microcode updates, but so far that hasn't been the case.

What really irks me is that no one is stepping up to confirm anything, not Intel and not the mobo manufacturers. Probably because they are afraid of financial repercussions, but it's highly annoying when your early adopters spend so much money on your gear and then have to troubleshoot very serious and very annoying problems on their own.

I haven't read the thread at Tom's yet, but this sounds exactly like the issue I had with my Haswell MacBook Air. The machine had infrequent crashes (maybe once every three months) and when it crashed it just stopped dead. The screen and mousepointer froze completely and it had to be power cycled. No traces in any Windows logs. The crashes happened during low load or idle.

I tested everything I could, but could never reproduce the issue with any stress tests. I suspected the issue had to do with the SSD, but couldn't prove it.

It took 20 months before the SSD finally gave in. It started giving SMART errors and both Windows and OSX recommended immediate replacement. Of course, Apple refused any sort of replacement or compensation. I replaced the whole machine, but obviuosly not with one from Apple.

With this said, have you tried replacing the disk(s)? What disk(s) do you have?

It's a brand new Samsung 850 pro that I bought for this build. Who knows, you could be right. Come to think of it, most people in the Tom's thread have a Samsung ssd as their system disk. Unfortunately I don't have a spare ssd to use for testing, I'll see if I can get my hands on one.

 

[crashtech]

Even a spare spinner would be valid for testing purposes.

Fair enough, the problem sometimes doesn't occur for a week. The thought of installing windows and using it for a few weeks on a mechanical drive scares me

 

[superstition]

The entire platform got minimal Windows 7 support. Like it or not.

Then Intel shouldn't list it as having equivalent support, like it or not.

You got a free upgrade to Windows 10. So use it.

Nothing is free. The things that people like about 7 aren't available in 10.

That has been my experience. Their UD3P 2.0 board has a cold boot multiplier bug (any multi higher than 22 causes the board to not boot) and multiple people in one forum alone, myself included, have found it. Their support just gave me the run-around to the point that I gave up.

 

[superstition]

So now dGPU users should expect crappy drivers from AMD and NVidia if they are running the "legacy" OS, W7 on their latest GPUS? Is this some kind of lame joke?

That argument is absurd and only shows the blue tinted glasses some "posters" have in this subforum.

In another forum there is a topic about the delidding craze due to recent data that shows a 16C heat bottleneck at stock for a 6700K and 20 or more when overclocked, due to the use of substandard TIM.

There are vociferous posters who claim that we should be grateful that Intel only offers quad i7s with this TIM rather than using something with effective transfer — among other bizarre beliefs. They also refuse to acknowledge that the primary cost in using decent thermal transfer material would be the end of profits from killed chips from the delidding practice.

Anyone know of a fix yet for the HD520 crashing issue in Win10? I have a Dell Inspiron 11 w/ Skylake i3 (HD 520 graphics) and no matter which Intel driver I try from October to the latest, I get constant crashing (display driver stopped responding and has successfully recovered). Sometimes the crashing happens every few seconds non-stop until I just turn the laptop off and back on, but as soon as it turns on, it starts crashing again.

I've already tried wiping the hard drive with DBAN and fresh installing Windows 10. I've tried installing a new hard drive and have tested the RAM with memtest+ and HCI memtest for at least 24 hours each.

I think it's worth a try, since you've tested pretty much everything else.

By the way, I have a 6700K system with a Samsung system drive myself (see signature). Built it in November and it has worked quite well. However, I did have one restart while the system was idling. I was not in the same room, but I heard the beep when it rebooted. I checked the logs, but couldn't really find anything of interest. It hasn't happened more than once and the system was running mildly overclocked, so until now I didn't really think much about it...

I'm running Windows 10 fully patched. Since the crash I'm running fully stock and have updated BIOS to the latest version. I'll let you know if something comes up.

Do you use the driver at Dell or Intel? Dell may have a special setup.

 

[Synomenon]

Tried both the latest Intel drivers for the 520 and the latest Dell has for this model.

 

[ShintaiDK]

RMA it to Dell.

I also had this issue in my 530 for the xps 15. I updated to the latest Intel drivers after a clean install and I haven't had any issues yet. You can also try the beta Intel drivers. There is a note in the changes saying something about the crashes.

That's what I also have.

 

[VirtualLarry]

I can't use 4352. 95% of the time, if I let it go into monitor sleep mode, it never wakes up or comes back. Ala "AMD black screen on wake" problem, with their older 7790 / R7 260X cards.

Edit: Nope, standard HDMI (non-4K) connection to a Westinghouse 24" 1080P HDTV.

Nice find. Iris 540 is significantly faster than HD 520, unlike previous 'U' models with bigger GT3 iGPUs. Dropping the low-end dGPUs also means thinner and lighter designs (perhaps cheaper too).

Waiting for Iris 550 and Iris Pro 580 results.

Any review for the Core i5 model yet?
