My NUC Skull Canyon keeps losing HDMI video connection. If I try to log in as a different user (say, I reboot the system, log in as user X, then try to log in as user Y), after entering credentials, the screen goes blank and my TV shows that there is no HDMI connection. I need to unplug HDMI cord from either TV or NUC, and then plug it back to get video restored. It started happening recently. I tried using a different HDMI cable (brand new, different brand), but it did not help. I have all the latest Windows 10 (x64) updates and as of writing Intel Driver Assistant shows no available updates. Any ideas?

I am having constant screen flickers and blackouts. I have tried various remedies including all recommended driver updates. I am currently running the Radeon 18.6.1 driver and Intel 630 version 24.20.100.6136 driver. If I were to guess I suspect it has to do with HDCP not working correctly as I sometimes get a green screen that corrects after unplugging video cable that is HDMI at the moment.

Funny thing is that if I uninstall the AMD drivers package I get flawless video. Of course I get no sound through the HDMI cable but video problems go away and video runs at 64hz. Video really is good this way even at full 4k so I may just work around the sound issue. any suggestions or recommendations would be appreciated.

Hey guys, just got my Hades Canyon yesterday and I find some werid behaviour about the fan and temperature.

For example, when it's on idle state, the fan is very quiet that I barely can hear. but as soon as I open a software or even open a folder, the fan kicks in and it's very audible.

I open up XTU and find out the CPU temperature would go stright up to 70C - 80C, and drop down to normal temp(40C-50C) rapidly. So the CPU basiclly jump up and down in a large range.

I checked the default cooling options in BIOS, find that minimum temp is about 60 (can't remember exact number), so everytime the cpu goes up above that temp, the fan would kick in with high speed. Is there any time-based options for fan setting? for example if the CPU temp goes above 60C, can I set the fan to speed up only if the CPU temp stays above 60C for 5 seconds or 10 seconds, so the fan won't speed up unnecessarily?

I know for now the best solution may be change the minimum temperature to about 70-80C to avoid some fan kicking in, but a time-based settings would be cool.

anyone can share some good cooling settings for Hades Canyon? thanks

I'm having trouble booting a "Live"  USB. This image claims to be bootable on legacy bios and UEFI only hardware.

It does boot fine on legacy bios (UEFI class 0) machines but it hangs on "Loading Linux.." on my NUCS  (UEFI class 3)

I tried 2 different bootloaders.

The permanent SSDs on these NUCs both are running Debian Stretch dual-booting with other OSs but they have initrd images

*The current Live USB I am testing was designed / is configured for  running with no initrd or initramfs, relying only on /sbin/init to get inital rootfs mounted.

I flipped on and of the legacy bios flag on the ESP partition and added commandline bootparams as well as recompiled the kernel.

My question is does the UEFI firmware of this box need to see an initrd or initramfs image at boot time; configured in the bootloader?

Thx

after upgrading to 0041 BIOS when i select F2 to get to the BIOS Settings my HDMI monitor goes dark.

using a VGA to HDMI adapter works however to a VGA monitor.

Anyone have a workaround to this?

Hi All:

I experienced the following issues in my NUC6CAYH, lack of support for DTS-HD-MA and other HBR audio file formats, lack of support for PCM audio at 192/24 encoding, applying the latest firmware and drivers limited the gizmo to 96/24 audio, etc.

After some proofs I discovered a couple of things:

If you start playing HBR audio and then turn off the TV or monitor, my receiver started to bitstream audio at 192/24 effortlessly, even the so-called HBR file formats. The receiver correctly detected the HBR formats and worked ok.

If I turned on the screen (a Samsung 4K Smart TV), the sound went mute. Turning off the TV allowed to recover the audio.

I suspected either a bandwidth issue with the HDMI 2.0 LPSCON implementation or a case of just awful driver implementation.

Then I tried to use the ASIO4ALL drivers, which are sort of a universal ASIO solution for sound devices that do not come with a manufacturer supplied ASIO driver. It enables the audio software to get direct access to the hardware, bypassing all the WDM stuff in between.

And guess what?

Using the ASIO4ALL drivers, I can play audio at 192/24, even multichannel audio (8 channels). The problem with this approach is that the audio decoding is being done in the NUC's CPU, so in Task Manager I could see CPU loads of up to 70% when decoding a 6 channel SACD ISO file.

The receiver gets LPCM audio up to 192/24 in 8 channels.

So, I defaulted the audio software player to use the ASIO4ALL drivers and decided to waste no more time trying to make WASAPI work (I'm using Jriver MediaCenter 23).

By the way, I'm using the latest Intel drivers, which are limited to 96/24 audio. The ASIO4ALL drivers don't seem to care about this, playing audio at 192/24 just fine, although with heavy CPU load.

So, here goes a question to the Intel guys: Is this a hardware limitation or a software driver limitation? How is it possible that using a third party supplied ASIO drivers enables the NUC to do things that seem impossible with the Intel-native drivers?

By the way. I also discovered that the problem with HBR audio decoding is due to the poor ARC implementation in the Samsung Tizen 4k TVs. The ARC signal can be received by the TV as either PCM or bitstream, but the return audio signal can be only PCM, Dolby Digital, DTS or Dolby Digital +.

I guess that is why HBR encoded files play flawlessly if I turn off the TV: HDMI audio no longer uses ARC, it starts being decoded by the receiver.

The only alternative that I found is to use an HDMI audio extractor and splitter called HD Fury. This splitter detects the EDID info of each device that it is connected to and delivers what the device requires. Nice, but at 150 USD it seems to be a bit too expensive way to solve the 130 USD NUC's problem.

Since I use the NUC mostly for audio, I can also leave the TV turned off and control the Jriver Media Center software via its web server or it's Android app and get HBR support via WASAPI. But this is somewhat cumbersome.

So, I suppose that the life expectancy of my NUC will be reduced by the heavy CPU load while playing multichannel HD audio, but at least I can still use the darn thing.

Go figure.....

Hello. I just bought NUC6CAYH. I installed one memory card 8GB (8 chips on each side = density 4 Gb) in lowest socket, closest to the mainboard, also tried other socket - power led is solid, but there is no image on monitor via hdmi or vga.

If I took off memory card - power led is blink 3 times in a row - also no image.

in specs "Support for up to 8 GB of system memory with two SO-DIMMs" - so I should use 2 cards with 4GB to make 8GB total, not one card with 8 GB?

NUC6CAYH doesn't support one memory card 8GB?

The withdrawal of the Express BIOS updates for new versions means that there appears to be no way to remotely update system firmware on NUCs that don't support AMT (which is almost every model).

What solution does Intel have for those who need to update firmware remotely (i.e. without being physically present at the machine)?

This is a serious issue that has the potential to become an emergency if there's a sudden requirement to update firmware on Intel NUCs - for example if serious security flaws are discovered. I would appreciate a proper, thoughtful response from Intel on this issue.

So, I just ordered an NUC8i7HVK, and would like a second power brick to save lugging it around all the time (home<-->office)...

No love at Intel® NUC Spare Parts yet :-(

From review pics I see the NUC comes with a Lite-On brand power supply, model "PA-1231-12".

The Technical Product Specification states that's a 19.5v/11.8A (230w) power supply with a DC "barrel" style plug having 7.4mm/OD 5.0mm/ID shell (ground) and inner 0.8mm (19.5v) contact.

So, the question then becomes, where to get one?

I can't find anyone selling identical Lite-On power supplies directly online?

There seem to be a variety of laptops using similar power supplies. It's worth noting that Lenovo uses a "PA-1231-12LA" (note the additional "LA" on the end) model with an incompatible square plug.

Interestingly, the tech spec also states:

The kit has a power sensing circuit that Manages CPU power usage to maintain system power consumption below 230 W. It is recommended that you disable this feature (via BIOS option) when using an AC-DC adapter greater than 230 W.

Which makes me wonder if trying to find one of the 280w power supplies MSI specs for their gaming laptops might yield a performance increase (at least for a burst until you hit the TDP wall)?

Anyhow, searching Amazon yields an HP branded one ("HSTNN-LA12"), and one from Delippo, so I'm wondering if I should give one of those a shot?  I just want something reliable that won't fry my NUC, but the marketplace for these things sure is sketchy :-(

Hello together,

my name is Oli from Germany and I have recently purchased a NUC8i7HVK. I use it with a Samsung 970 Pro and a 960 Evo and 2x 16GB Crucial Ballistix Sport 2400 (BLS16G4S240FSD).

I also have a Skull Canyon for about 2 years now and I was so convinced of it that I thought, I need the successor now.

I have installed Win10 Pro and everything seems to work so far, except for one thing that I have not gotten fixed yet.

Every time I reboot the NUC, the Intel NUC-startup-screen appears for a short time, then it turns off completely (lights off) and immediately comes back again to the NUC-screen, followed by a message:

"Error: BIOS has detected unsuccessful post attempt(s). Possible causes include recent changes to BIOS. Performance Options or recent hardware change. Press Y to enter Setup or N to cancel and attempt to boot with previous settings"

I haven't done any changes, but the message appears anyway. If I then press N or either Y and go to the BIOS and save, it starts again 1x normally. The whole thing does not occur on complete shutdown and manually switch on again, but as I said only with reboot. Although I can disable the message with the help of "Disable Failsafe Watchdog" in BIOS-settings, but the "double" reboot with 2x NUC startup-screen and short off in between, still remains. I also have tried different BIOS-versions, but it's still the same. I would be glad if someone could tell me if this behavior is known or what I could still try to do about it or if it could possibly be a malfunction.

Thanks in advance

Oli

Hi everyone,

The RealSense section of the Intel Click online store is listing an upcoming bundle deal of the NUC 7 and an Intel RealSense D415 depth sensing camera.  It is not buyable yet but you can check out the details.

Ready to go Intel® RealSense™ NUC™ complete kit (BOXNUC7I3BNHXF + D415) - Intel® RealSense™ Depth Cameras

Hi all.

I am having a problem since I installed this NUC. It is running Windows 10, since the first boot it sometimes shows video through HDMI connector and some other times it doesn't.

I have updated to lastes BIOS, video and monitor drivers with no result. I bought a new HDMI cable and tried with some other I had near by.

Always same result, sometimes it boot fine and some other it doesn't shows any video. I have tried as well with an old NUC with miniHDMI connector and it works always, even when it boots without video I change cables to that other NUC and works.

Then I bought a USBc-HDMI cable and now things changed: I have video in POST boot but no video on Windows login screen. I detach and reattch USBc cable and video shows. BUT, with no sound on windows.

I have resintalled again Video and audio drivers, and some other pieces (Network, WIFI, SGX, everityng I found on Intel web).

Monitor is AOC E2275PWJ, and I have installed this driver as well. I have played around with some BIOS settings, like enabling HDMI CEC and setting default display port to USBc.

No results. As a resume:

- When connected to HDMI I have no video at all most of the times. I have to poweroff and power on until it shows video.

- when connected to USBc I have no video on windows login, I have to reattach USBc cable. No audio in this case.

thanks

I'm toying with my new NUC7CJYH with Linux (idea is to make replacement Kodi box out of it) and I have serious troubles trying to connect it to my TV. Things work OK when I connect it to my desktop DVI monitor via HDMI-DVI adapter - I can boot from Lubuntu LiveCD, install Linux and Kodi and video works fine. But when I connect it to my old tried TV box (50" Samsung regular full HD 1080 display) via HDMI thing immediately break. Here is what I see:

• Splash screen shows up normally (showing "Intel NUC")
• I can get into BIOS pressing F2 and it works fine too
• Going into Linux boot I can see GRUB in text mode
• When Linux switches to graphics mode TV does not show anything, in fact TV just says "No Signal" as if NUC does not send anything to HDMI.
• This happens both with LiveCD on USB flash (latest Ubuntu 17.10) and with Ubuntu installed on SATA SSD.
• I tried to play with BIOS settings changing every possible option, nothing helps
• I also tried to change Linux video driver in X11 between intel/modesetting, does not help either
• Even if TV does not show any picture I know that Linux boots and Kodi start OK, I can connect to the box with VNC and it shows expected picture, Kodi says it's configured for 1920x1080 display, just as expected.
• From VNC I tried to change Kodi screen resolution, and that sometimes makes NUC to show picture on a TV, but it is not very consistent (works more frequently on lower resolution, but almost never for 1080p).
• I tried it also on my other TV, 1080p LG, and it has the same problem.

I'm not sure what else to try, but to me it make my new NUC unusable (even before I get into audio over HDMI step which I expect to be a problem).

Does anyone see anything similar to my experience, or did you manage to make it work?

ven_8086&dev_3198 is what I seek.  The gfx driver package for this unit includes an audio driver for devices 2809 to 280F -- not helpful.  The prior release from March has the same.  The Driver and Support Assistant offers nothing.  Windows Update offers nothing.  I'm lost.

Verified the M.2 slot is enabled in BIOS Setup:

1. Press the F2 key during boot to enter BIOS Setup.
2. Select Advanced> Devices> PCI.

M2 shows in PCI not in Boot devices

Hi there,

This issue is pretty similar to this one, but I was encouraged to create a separate thread. My problem is with NUC7i3BNK, BIOS version v65 (latest as of this writing). I realize there is "Fixed CEC not working correctly" line in the release notes for v65 BIOS, but it didn't fix the issue for me, unfortunately. NUC successfully suspends after turning off the TV, but it can't wake up when it's on. It wakes up from USB keyboard ok, however. Here is the information on my device:

1.

2. Product Name: NUC7i3BNK

    Version: J31188-312

    Serial Number: G6BN81200Q62

    MAC: 94:c6:91:1c:b9:be

3. Ubuntu 18.04, kernel 4.15.0-24-lowlatency

4. 1 x Micron DDR4 4GB 2400 MHz / PC4-19200 SO-DIMM (4ATF51264HZ-2G3B1)

5. No SSD, No HDD, the device is PXEBOOTed

6. Logitech Media Keyboard K200, Logitech M105 Optical Mouse

7. The TV is Samsung 55" 4K UHD, Model number UA55MU6103KXXT

Hello everybody,

I own a NUC7CJYH with the latest bios version 0039.

I have the problem that after booting into linux the CIR does not work after a few seconds.

OS: Debian Jessie or Debian SID

Kernel: 4.17.2, 4.17.1, 4.14.52

Driver: ite-cir

There is no error message (dmesg / journalctl) or an other notice. The ir codes are simply no longer registered (ir-keytable -t). Unloading all RC modules and reloading them will not help either. Just a reboot helps.

I'm not alone with this problem:

https://forum.kodi.tv/showthread.php?tid=298462&pid=2730976#pid2730976

On Windows, everything is fine.

Any suggestions?

Thank you

ciao a tutti,

non riesco a capire perchè dopo un riavvio pianificato di windows le ventole del nuc corrono alla massima velocità, per ripristinare il problema devo procedere allo spegnimento del nuc

Hi, aber several crashes I tried to updated The Bios and Install a new OS in hope to get rid of several issues.

Via Internet it finds not the newest 0018 Version. So i tried to update via usb stick.

But everytime the Nuc reboots it get stuck.

Same happens when i pull the jumper as discribed it doesn't find any file.

I tried above steps with different USB sticks. diff sizes usb 2 usb 3 and so on.

Same result happens when i try to install a new Os via usb.

At last i tried it with a ssd and this also won't be recognized and get stuck in a black screen.

A second Intel NUC with same Bios shows the same Problems, only his also hdmi strikes.

So i think I told you everything i've done so far and I hope someone has a suggestion how to proceed next.

Feel Free to ask any question that might be still open.
