Hi I've been using Win10 with the Nuc (nuc6cays) for a couple years now but like others I'm having trouble getting my new Samsung HDTV (49" QN49Q6F) to recognize it through the HDMI port.  I have searched through the forums and gotten some help and tried a few things, but I'm having trouble with upgrading my NUC.  I've successfully flashed the bios with AYAPLCEL.86A.0049.EB but I'm confused about the HDMI firmware upgrade "NUC6CAY-NUC7ixBN-HDMI-Update-1.72".  I found this reference in an old post as a possible fix to the HDMI problem, but I'm a little confused on how to work the "Bobcat Aux ISP Tool" software.   It seems I'm using this program to run the files found in the "bin" folder, but no matter what file I run, it fails.   First all, is this firmware update still relevant?  When it comes to flashing bios and firmware/driver updates I'm of the mindset that if it ain't broke don't fix it.  If anyone can advise me on which updates to apply to fix this problem please let me know.   I was able to find a tutorial on how to install the HDMI firmware, but it said nothing about how to use Bobcat and I don' know what "FW" refers to.   The other possible problem is that the tutorial says I must be hooked up to an HDMI 2.0 compliant device which is impossible in terms of the Samsung as hooking up is the problem.  I did run bobcat while hooked up to a different HDMI monitor, but I was unable to be certain if this was HDMI compliant.

Beyond that I've confirmed the HDMI cable is fine and that HDMI works fine with the HDTV using a different PC.    I spend two or three hours trying to get the HDMI to work including returning and getting the same TV thinking the problem might be with the "ONE CONNECT" box that comes with the TV.    This box attaches to the TV with it's own priority cable.  At one point, the one connect box feel 2 feet to the floor, then when I picked it up, the HDMI port was recognized, but only for as long as the TV was on.  After that it went back to being unable to detect the PC, although it's clear the HDTV knew something was connected to the HDMI port.   Hot swapping didn't work and I've tried all 4 HDMI ports available on the TV.   I don't get a blank screen or a boot screen or anything.  Just the Samsung screen showing it failed to establish a connection.

I realize there are other posts on this topic which I am still exploring. 

Hi,

I've set up my Hades Canyon and was able to on first boot get Win 10 installed, added all the drivers, rebooted a couple times along the way. Didn't touch any BIOS settings, just wanted to get everything installed first before tweaking anything. I left the system off and went to boot it the next day and saw the message "A bootable device has not been detected."

I promptly went into BIOS and my Intel 760p SSD was no longer showing in the PCIe devices list. I had installed it into SSD Slot A. At this point I was on BIOS *.0029.*, so I went to see if a newer BIOS had been relased. *.0040.* was available so I installed that. System still refused to detect the installed SSD.

Only after unplugging and reinstalling the SSD, into either slot A or B, does it boot from SSD. But if I dare power down and attempt to restart, I'm stuck with the bootable device not detected message until the next time I manually intervene and reseat the SSD. I've installed SODIMMs and m.2 SSDs in the past and was sure to seat the device pins properly. I'm running out of ideas here! I've even cleared CMOS via the BIOS_SEC jumper inside the case.

I'm very confused because this isn't a total failure, as I was clearly able to make use of the SSD up until it quits being detected. Thanks in advance for any suggestions!

Hello,

we have Patriot Scorch M.2 128GB in PC Intel NUC7i3BNH. After we switch off the computer and unplug power cord then the bios does not find the Patriot M.2. We have to do some change in BIOS and then bios find the disk.

We tried two last BIOS but no change.

Do you have some ideas?

Regards

Roman

Hello and good morning.

2 days ago i got the Biosuptdate from 57 to 61. From this Moment on my NUC cannot wake from S4 or S5 with my IR Command. I have to use Power Toggle 2 or 3 times to wake my NUC.

I replaced BIOS back to 57, but than I have Problems with my Optane and the Nuc doesn't start my windows. BUT, he wake up with the first PowerON command from my IR. After flash to 61 I need 2 or 3 times to wake... Than i change th IR Driver to the last older version, but there is no change...

In some German Boards a few people have the same Problem with NUC6 and 7 after flashing the new Bios...

For me I have a solution to wake my NUC. I use CEC and I can wait for the next BIOS. So use my note as information...

Kind regards

Uwe

Have the NUC6CAYH...

running win 10 ent...

wanted to update the hdmi firmware to make it all compatabel with my Denon AVR-X2300W.

so downloaded the 1.72 firmware update from intel page... run it...

But the update failed and now its like the system dont have any hdmi port anymore?

is there a way to roleback or do some factory reset to make it work again?

if i try to run the patch software BobcatAuxISPTool.exe again it just say that there is no adapter...

i have tryed restarting the nuc... restared the Denon... pulled the hdmi out and back in again.

but there is no sign of life or even that the hdmi exit anymore...

need some help... very useless to have a nuc with not hdmi port

Hi,

I bought a external USB ASUS SBW-06D2X Blu ray in several month ago.

At beginning, my NUC can detect blu ray device and show it in File manager after plug-in it.

However, after several updates (BIOS, software, ...), once day I tried to plug it in to my NUC, my NUC can't find it.

I mean, Blu ray device doesn't appear in file manager and there is no yellow bang device in device manager.

Then I tried to connect Blu ray device to another PC, another PC can recognize it and see it in File manager. So I think Blu ray device itself is fine.

I also checked that USB port is okay on my NUC because USB flash disk can be recognized on the same port.

Do you have any idea why USB blu ray player is not recognized now?

Thanks in advanced.

On my NUC8i7HVK appears a problem after most cycles of monitor sleep and wakeup.

Just after wakeup screen looks noisy like attached photo and every time I need to detach monitor and attach again or reboot PC to makes it normal (another attached photo).

BIOS update to version 0044 do not fix this problem.

Enable or disable Intel HD Graphics in BIOS settings also do not take effect (now disabled).

I uses latest available for download Radeon graphic drivers 24.20.11016.4.

Problem appears on any connection type HDMI or mDP with any resolution from 1920x1200 to 2560x1600.

Video resolutions of 720p and lower play just fine. For 1080p videos, however, the Nuc6i3syk can't quite keep up and videos are choppy and unwatchable.

Does anyone know if an external graphics card in a usb/hdmi adapter would solve the problem?

If an adapter would help, any suggestions on a usb/hdmi adapter that is compatible with Linux (Mint 16)?

Thanks!

I have been unsuccessfully trying to use the serial port exposed on the PicoBlade header on the NUC7i7DN for several days now.

I'm trying a simple loopback test, which doesn't work. I'm on the latest BIOS (v47) and the Serial Port is enabled in the BIOS. On Linux, it seems to enumerate as /dev/ttyS0. When sending data to the port's RX pin and trying to see it in `screen`, the output is garbled and/or just random.

Any help would be appreciated!

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

Intel NUC6i7KYK

Display: 4K 60Hz

Iris Pro GFX 580 Version: 24.20.100.6025

HDMI Ports & Cables: 2.0 w/ HDCP 2.2

Browser: All of them

Intel HDMI Firmware Updater Version: 0x07_0x20

ISSUE #1: If I click a movie's page on Amazon Prime, display goes blank every time. Screen shows "No signal detected". It won't display anything again until I Shut Down/Hibernate the NUC. Removing the HDMI cables or turning off TV won't solve problem. I've noticed this only seems to happen on sites with DRM content. A few examples are: 1, 2, and 3. Tried GFX update version 24.20.100.6136 and same problem. Currently experimenting with 21.20.16.4860, but it's just as bad so far. It appears the only way to ensure the display doesn't go blank (in FireFox) is to disable the Widevine Plug-in. But then Amazon won't allow movie streaming at all. To watch a film, I must enable DRM/Widevine, Hibernate, Power back up, then the page suddenly works fine until I click away. What leads me to believe this is a NUC graphics issue is that it happens regardless of browser, and only on my 4K display. NUC also completely froze up on YouTube videos a couple times. None of this happens with my 1080p display connected. Nor does it happen when my 4K TV resolution is set to 1080p. Any suggestions? I'm currently awaiting response from Amazon also.

ISSUE #2: HDCP 2.2 devices not recognized by Amazon (again) at 4K 60Hz. This issue occurs no matter what version graphics firmware I use. But if I decrease the display frequency to 30Hz, HDCP videos suddenly work as they should. And again, they also work fine if I decrease the 4K TV's resolution to 1080/60. I'm hesitant to believe this is proper functioning.

I'm pretty certain the two issues are related through the Pro 580's processing of 4K graphics, but not sure how/why. If anyone knows of other websites with CRM/HDCP 2.2 mandated videos where I can compare to Amazon, I'm all ears. Don't have access to NetFlix though.

When re-assembling my new NUC7i7DNH1E after installing memory and storage, I think I screwed one of the main rubber-footed chasis screws in too far and now it just spins in both directions.  The typical action of trying to lift the lid to provide upward pressure while pushing down to keep the screwdriver firmly in the screw head isn't helping.

I took off the top, but it doesn't look like I can get to anything from that side.

Any suggestions on how best to get the screw to catch something to start unscrewing?

I currently have a NUC7i5BNH.  The issue is that the first time the computer boots in Windows, the Thunderbolt 3 eGPU is detected when attached.  However, if I sleep the computer and attach the eGPU, it does not show up in the device manager, and furthermore, the computer cannot properly sleep or restart.  Please help :/

Hi all,

Just got myself a new LG 65B7 TV

Hooked my NUC to it - it switched to 4K automatically.

I has also able to change the output to 60Hz via the Intel management utility.

However, I do not see an option to change the color depth or format.

I saw some screen captures in other topics where people have an "advanced" in the "display" menu - while I do not.

Is it something I have to enable somehow?

Maybe the missing settings are hiding there...

Anyway, my current settings are stuck at 4K@60p with 8-bit YCbCr420, and I do not see any way to change those.

Updated the graphics drivers, flashed HDMI firmware, flashed BIOS, Windows is updated to the creators update.

Regarding HDR - I do see the toggle - but when toggled - it just goes back to being off.

Any advice would be greatly appreciated!

When I was using Adobe PR, I chose "Mercury playback engine GPU software (OPENCL)" To cause my edited video to be abnormal.And my graphics driver is the latest version.

Is it possible to overclock this NUC, for a short amount of time (30-60mins)?

I do some intensive tasks such as LR/PS, or even a quick gaming session, wouldn't mind a tad more oompf for that time frame, I tend to take breaks every hour or so.

If so, how, and what steps are recommended?

Cheers!

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.

Hello,

I am using an Intel NUC7i5BNB,

On one of my NUC's, NUC1 was running BIOS Firmware 49 version ( BNKBL357.86A Version:0049 )

On my other NUC, NUC2, I updated the BIOS to the latest 65 version. Then followed all the steps to create a custom BIOS (myCustom65.bio) file to include the 65 major revision update along with my own customised BIOS settings using Intel Integrator Toolkit. I modified certain BIOS Power Settings and certain BIOS Boot Settings in my custom settings.

Now when I tried to update my NUC1 with myCustom65.bio, even though the update from 49 to 65 major revision was done successfully, not all of my custom settings got applied.

Only the BIOS Boot custom settings were applied, but the BIOS Power custom settings did not get applied.

Please let me know what I need to do to ensure that all of my custom settings gets applied with my update file.

Thanks a lot.

Regards,

FST

Hi all,

l got a NUC7i5BNH from a couple of months which does not work as expected, I'll try to make it clear to understand and reproduce.

My previous NUC was a Skylake one, so starting with the new Kaby Lake unit I soon noticed it couldn't reach CPU package C-States lower than C2 in Windows 10 when CPU is idle and the display is powered on:

this produces higher temperatures, higher power consumption and higher noise than expected (and necessary), so I started investigating from BIOS configuration.

After some testing, and with my great surprise, I found that "Legacy boot" option disabled was the culprit for this behaviour.

Premises:

- Unit is NUC7i5BNH equipped with 2x16GB RAM Crucial CT2K16G4SFD8213 and M.2 2280 AHCI SSD Crucial CT500MX200SSD4 MX200

- Operating system used for testing is always an UEFI clean install of Windows 10 x64 1803 up to date (latest build 17134.12) with no crap/trash, just a clean system for testing purpose

- Drivers are up to date as per NUC7i5BNH Intel support page

- UEFI firmware is up to date (BNKBL357.86A Version 0065 6/6/2018)

- BIOS was always flashed via jumper recovery (F9 default settings loaded after power off and power chord uplug)

- NUC is connected to a DELL display via HDMI port or to a Samsung Smart TV via HDMI port (both display are full HD resolution 1920x1080), with same results

- Monitoring software used is HWInfo via its sensors interface

Better issue description:

BIOS default settings enable both "UEFI boot" and "Legacy boot":

with this configuration, when CPU is idle C-States work as expected and CPU can reach package C8 with the display active, using both "Balanced"* and "Power Saver" Windows 10 plans (* to get C8 with "Balanced" powerplan may be necessary  to enable AHCI Link power management (via Windows registry) and changing the value in power settings gui to "HIPM+DIPM" or "Lowest").

When display goes off due to power saving timer, CPU can reach lower C-States (C9 and C10)

This is the expected (per Intel docs) behaviour, so power comsumption, heat and temperatures get benefits when there is no load.

If  "Legacy boot" option is disabled, when CPU is idle can reach only package C2 state if the display is active.

When display goes off due to power saving timer, CPU can now reach package C8 and lower (do note that if you just unplug HDMI cable or manually power off the display via power button, CPU still remains in C2).

This is not the expected behaviour, because system cannot get advantage of its lovely built-in power saving features.

I am an IT-Pro guy and a passionate user, so I tried to find a solution by myself but no luck:

- I tried changing any related or unrelated bios setting in every crazy combination possible without any effect, you need "Legacy boot" enabled

- I tried any available graphic driver for this unit and also generic non-NUC from Iris Plus 640 page (newer tried was Version:24.20.100.6136), no difference

- I tried tuning every Windows power setting - also advanced hidden ones - in every power plan, but no difference

- I tried also (just for fun) loading Windows 10 from USB drive with no other drive connected to the unit, no difference

Do note the same thing happened on previous BIOS version I went through before last revision (0062, 0063, 0064), so downgrade to that revisions is useless.

Do also note that any recent Linux distribution I tried (Kernel from 4.15 up to 4.17) do not suffer this problem:

also without loading firmware blobs on boot, CPU can reach lower package C-States - as Intel Powertop reports - just as expected also when  "Legacy boot" option is disabled in BIOS and the display is active (may be necessary tuning some options to enable all power saving features, but it is expected and works fine).

Paradox here is Windows 10 is the only supported operating system by Intel for this NUC and - as per following Intel recommendations - should be installed only in UEFI mode to avoid issues.

Supported Operating Systems for Intel® NUC Products - "UEFI Boot is required to install Windows 10 - this is set by default in BIOS Setup. Using Legacy Boot results in multiple errors in Device Manager."

Some thoughts:

I think it is clearly a bug, it shows itself only in Windows 10 but I do not think Windows 10 is the culprit itself:

as reported, leaving "Legacy boot" option enabled everything works as expected, so I suppose this problem is bios related but obviously I can be wrong (as I never thought that such option could have such impact on power saving features).

UEFI and legacy boot initialize hardware in different ways and some of the features involved in power saving options are based on firmware blobs, anyway this is out of my control and I just don't have any other idea on how to try fixing it, so I hope someone can "pass the ball" to the right team and investigate about this issue, which could be present on other Kaby Lake NUCs as well.

To me and - I suppose - to the largest part of owners and/or potential owners - leaving "Legacy boot" option enabled is not an actual solution nor an option because:

- it prevents booting via UEFI PXE and micro sd slot (due to PCIe interface)

- it prevents (or may prevent) booting from NVME PCIe SSD, and if you disable it you'll loose idle power saving features

- if "secure boot" is needed and so enabled, "Legacy boot" is consequently disabled and you'll loose idle power saving features

- power saving features like CPU Package C-States and Speed Shift are really important arguments of choice when buying these units and should work as expected at least in the only OS supported by Intel

Steps to reproduce:

To get Idle C-States NOT working with display active:

- In VisualBIOS, load BIOS default settings with F9 and disable "Legacy boot", save with F10 and confirm.

- Boot Windows 10 and monitor CPU C-States with HWInfo (or any other similar software): C2 will be maximum package C-State reached in idle  with every power plan when the display is active.

To get Idle C-States working with display active (the expected behaviour):

- In VisualBIOS, load BIOS default settings with F9, save with F10 and confirm.

- Boot Windows 10, select "Power Saver" powerplan* and monitor CPU C-States with HWInfo (or any other similar software): C8 will be maximum package C-State reached in idle with the display active (C9 and C10 with display off via power saving timer).

* You can get C8 also with "Balanced" powerplan, but it may be necessary to enable AHCI Link power management (via Windows registry) and changing the value in power settings gui to "HIPM+DIPM" or "Lowest".

I hope it can be fixed, thanks in advance to everyone who can investigate about it.

Best regards to all the community,

M

Good evening. I have purchased/installed the new NUC7i7DNHE w/16 GB Crucial Ram PC4-19200 and 1TB Crucial SSD and OS Windows 10. The Windows software is up to date.

The video display Intel UHD 620 has driver version 24.20.100.6025. The internet connection tests at a solid 59-60 MBbit/s as well.

Resolutions tested include 1920 x 1080 and 3840 x 2160 at 60 hz.  Software tested include YouTube TV, Netflix, and Amazon Prime Video. Google Chrome web browser is being used.

Please let me know where to dive in from here to get this new equipment working smoothly.The image is crisp/sharp, but is not smooth with stutters. The stuttering is more pronounced when the camera pans.

The same videos will play back smoothly if we take the NUC PC out of the equation.

For example, if my Smart TV streams the software directly, the playback is smooth. Display used is a LG 65" OLED.

thank you.
