I have just bought an Intel NUC 8i5BEK. I ave installed Win 10 and all the newest drivers and bios from Intel download. When I try to use a loud-speaker system attached by the phone plug a get a sharp sound (sounds like a gunshot) on many occasions.(I have tried 3 different speaker systems, all the same problem). When I instead use a usb attached headphone or a Bluetooth speaker these sounds dissappear. Anyone , any Idea ?  Need some help

My NUC8I5BEK with INTEL 760P 256G SSD is connecting to Sony Tv as media center. However, once the screen off, i will never be able to wake it up by any means except to power it off and turn on again.

 

Here are what i did, but still cannot resolve this issue.

(1) Update all drivers and windows 10 update (1809)

(2) Disable deep sleep in BIOS

(3) 3 mins screen off

(4) never sleep

 

It is really annoying now as i have to set screenoff and sleep to "never"

Quantization range complete not working on usb-c to hdmi cable NUC8I5BEK

Good afternoon,

 

I'm using a usb-c to hdmi cable for my monitor because the hdmi cable is used to connect the tv.

 

I can't have the full rgb range on my monitor. I selected the option in "video" on intel graphics control panel but it's like if it doesn't apply the option.

 

On the hdmi cable it does work perfectly.

 

Please consider that if I uninstall intel drivers and use "generic microsoft driver" it has the complete rgb range, but obviously audio doesn't work...

 

I tried all the new drivers, but nothing.

 

Can you help me?

 

Regards

LED issues

$
0

I've got problems with the LED's not turning off after (what I think is a) Windows 10 Pro Auto Sleep feature, its not all LED's either, Front LED 1 and 2 works as expected, but the rest (Power Button, Skull, Eyes and Front LED 3) gets stuck in the last configured state after this happens, after installing the latest BIOS, with some hassle by underclocking the RAM, an hard power reset (unplugging the power) seems to solve this issue and its also the only thing that solves it, even though it's pretty annoying when it happens. Does anyone else have this? The Windows LED configure tool think it changes the LED's but nothing happens with the mentioned LED's, changing Front LED 1 & 2 works however. Even if I try to sleep, hibernate or shut down the device completely from Windows the LED's are still on after this happens.

 

Also, is is normal that the chassis seems to have a small gap that makes the led create a stripe of light underneath the unit like this?

Hi,

 

Has anyone else experienced system hang's > 5 minutes when using the XTU?

 

I've not used it in a while and not sure when it stopped working properly.

 

I've tested it for varying lengths of system hang-time - where no peripherals respond, but I have lights and display output and the utility doesn't change from the initial grey background with white type.

 

  • 5 minutes
  • 10 minutes
  • 15 minutes
  • 20 minutes

 

 

SSU attached.

Support for Consumer IR

I would like to use the consumer IR built-in to the NUC to control other devices on Windows 10.  Are there any programs that will learn/recognize IR commands?  If not, is there any documentation for how to programatically access the IR so I could write my own?

NUC6i5SYH dynamic constrast can't be turned off

On my NUC6i5SYH it seems theres some kind of dynamic contrast or "color-correction" that is enabled and that I'm not able to turn off.

This is especially visible on blueish/greenish scenes.

 

I got some recordings where is visible: Shared album - Kasper Plougmann - Google Photos

 

I tried disabling everything in the Graphics Control Panel, but that didn't do anything.

 

The same movie on Chromecast to my TV doesn't do this. But the NUC connected to my TV does the changing colors thingy.

I also tried other displays with the same result :/

 

What can I do?

NUC7PJYH: BSODs and hangs after BIOS update - 45 and 46

$

The first BSOD (KMODE_EXCEPTION_NOT_HANDLED) happened soon after BIOS update from 44 to 45.

 

After updating to 46 they became quite frequent. The last one said "SYSTEM_SERVICE-EXCEPTION".  Sometimes the PC just hangs typically, while in browser.  Once it hang at "Welcome" screen.

 

Before updating to 45 the system was rock solid.

 

Has anyone else experienced such problems after updating the BIOS?

 

Thanks,   Peter


Problems with EDRAM Frequency

$

Didn't realise I had a problem until I purchased other NUCs and comparing the speed of video conversions...

You can see from this video that my EDRAM is jumping to zero quite a lot, while my other NUCs don't do the same.

However If I reboot, sometimes it displays correctly, and also seems to be faster, but it only works correctly maybe 1 in 5 reboots?

It is not the memory as I have already tried different memory, when its like this my benchmark shows below 4Ghz, and when it isn't jumping to zero it is above 4.2

Any help would be appreciated.

NUC8i7BEH Unexpectedly restarts to "No Bootable Devices"

I've got a new NUC8i7BEH that unexpectedly restarts after several hours of uptime, sometimes idle and sometimes during remote use, and boots to No bootable devices found, with no drive activity light on the enclosure. If I press the power button twice, the unit boots normally (until the next time it unexpectedly restarts).

 

I've updated the BIOS to 0048, and nothing's improved. All drivers are up to date, per the Intel Driver and Support tool.

 

Running a Toshiba KSG60ZMV512G M.2 SSD as the Windows 10 boot device with a Samsung 850 EVO SSD as a secondary data drive (full System Support report attached).

 

Event Viewer records Critical Kernel-Power errors, event 41 category (63), but without much detail, followed by Connectivity state in standby: Disconnected, Reason: NIC compliance [ID 172, category (203)].

 

Any ideas? Happy to provide any other logs. Created an Intel support request as well.

 

M.2 NVME speeds on NUC5i3RYH and NUC6i5SYH mini PCs.

$
0

Good day,

 

I own several NUCs, I have a NUC5i3RYH and a NUC6i5SYH. My issue here is that I may be getting confused on speeds/performance so I just wanted some community input to help clear things up.

 

Checking specs, I upgraded the SSD in both these units to NVME, expecting better performance. I'm not particularly getting what I should be getting based on specs, etc.

 

The NUC5i3RYH is supposed to have PCI-E 2.0, ie: Generation 2 at x4. The product brief clearly states Gen2 M.2 slot with PCIe x4 lanes. Is this correct? For this device, I purchased a MydigitalSSD 256GB : MDNVME80-SBX-0256. I EXPECTED it to be getting between 1200-1500MBps on Seq reads and 1200-1400MBps Seq Write but I'm getting 1/2 of this @ ~ 825MBps and 750MBps. I don't know if my expectations are too high or if there's something else going on here. Of note, the BIOS says the M.2 is operating at x2 - 5.0 GT/s. This seems off. I would expect that the SSD should be operating at x4, no? I could be reading what the BIOS is telling me incorrectly, but I don't think so. 5GT/s seems to be telling me the card is being seen correctly as Gen2 but what I don't understand is why it's being run at x2 speed vs. x4. The only other way to read it is x2 as Gen and 5.0GT/s as the current speed, but that'd be incorrect based on benchmarks. Gen2 @ 5GT/s would essentially be PCI-E 2.0 x 1x speed and I would be getting 500MBps or less in that case. My next case also supports the former. Again, this is one huge question. I'm just trying to figure out if I'm doing something wrong here.

 

The NUC6i5SYH is essentially having the same issue. It's supposed to have PCI-E 3.0, ie: Generation 3 at x4. It product brief clearly states Gen3 M.2 slot with PCIe x4 lanes.For this device, I purchased a 512GB: HP EX920. This device is PCI-E 3.1 x4 and rated at ~ 3200MBps Seq reads and 1800MBps Seq writes. On my NUC, again, I'm getting 1/2 of this. I expect this SSD to be getting at least in the high 2000s to low 3000s for Seq read and 1400 MBps or higher for Seq writes. What I'm getting is essentially half of this, at 1600MBps Seq read, but 1400 or so Seq write. Again, the BIOS says the device is running x2 - 8GT/s which I take as meaning, Gen3 x2 which would on par with what I'm getting. So, what am I missing here?

 

Things to note/questions you may have:

 

I'm running the absolute latest Bios on both NUC models.

Running OS is Windows 10 x64 Pro on the i5, x64 Home on the i3. (The i5 is the HTPC, the i3 is the Work@Home machine).

Windows 10 is installed under AHCI mode, NOT RAID mode on both machines.

On both installations, the BIOS is correctly identifying the SSDs as NVME/PCIe.

I'm running the utility Crystal Disk, installed on the drive from the Windows store. I notice that most benchmarks are done when the drives are not the system drive, ie: they're D: or something else, never C: so maybe I'll get better results running from a portable or could consider that perhaps being the system drive is the issue? Though I don't see why it would.

Neither drive is operating at even 10% capacity. Both are actually at ~5% or so since once is an HTPC and the other a machine I use primarily for work, there's not much installed except for Windows and a few other programs.

I've been looking around for people who are getting/have gotten rated speeds on their NUCs but can't find any, ie: anything at all really relating to M.2 NVME speeds regarding NUCs. Of course, I could easily have missed results - I am after all human

 

The issue seems to be that the NUCs are running the NVME devices at x2 and not x4. Is there something I'm doing wrong here? Is there a way to manually switch it? Are the NUCs capable of utilizing x4? If not, why would they be advertised as GenX.0 x4? Why not advertise as GenX x2? Had I known, I could likely have purchased less expensive NVMEs.

 

Any help/assistance or information on this would be greatly appreciated.

 

Thanks in advance!

Intel NUC7I3BNH does not accept DHCP offer during PXE boot

$

0

So I am a bit confused right now since I am pretty sure I asked this question yesterday but can no longer find any trace of it.... So I'm asking it again.

 

We recently bought a NUC7I3BNH to test out as a replacement for our current fleet of clients. During the test we unfortunately noticed that it will not PXE boot because it does not acknowledge the DHCP offer of the DHCP server. IPV4 DHCP that is. We have not tested IPV6 DHCP since that network is not set up for that. The problem is there for both UEFI and Legacy PXE boot.

 

It is certainly not an issue of the port the NUC is connected on, as a different PC on the same port works fine for PXE boot and there is no STP or Portfast involved. Also the DHCP request does go through to the server and the offer does get sent out, but it never gets acknowledged by the NUC for some reason. I have attached the edited down packet trace for the DHCP request/offer process which is repeated multiple times by the NUC since it apparently never ACKs any of the offers. The NUC does successfully acquire an IP adress if you install a local OS onto it and boot into that, so the device does not appear to be faulty. The bios is also at the current available latest version.

 

I'd be happy for any sort of advice.

NUC8i3BEH not displaying 10-bit 4:2:0 YCbCr on Sony 75XF9005

Hello,

 

I have a nuc8i3beh which have connected to my sony UHD TV.

The sony can display UHD HDR content up to 4:4:4.

In windows I cannot get the display output to go to UHD 60Hz 10-bit 4:2:0 YCbCr

The max it will do is 8-bit with dithering, RGB.

 

Some things I checked based on other topics in this forum:

  • checked for latest bios/drivers
  • tried newer intel graphcs drivers, instead of the special nuc drivers
  • running windows 10 with all updates
  • running windows 10 on 300% dpi
  • several power cycles on the TV and nuc
  • TV is running in enhanced HDMI, NUC is on the correct HDMI port which supports uhd hdr
  • windows HDR is on
  • intel graphics YCbCR is enabled
  • I am using a cable which easily can handle 18GBps (and tried different cables)

 

Please help me to setup the nuc so it can display according to its max specs.

Thunderbolt HDR NUC7i5BNH

I'm testing connecting My 4K HDR10 capable TV to Thunderbolt USBC port using this cable from Amazon:

Cable Matters USB C to HDTV Cable Supporting 4K 60Hz in Black 9.8 Feet - Thunderbolt 3 Port Compatible for Macbook Pro, Dell XPS 13/15, HP Spectre x360, Surface Book 2 and More 

3840 and 4096 by 2160 at 60 HZ works perfectly using the above cable.

Problem is that I get no option to enable HDR in Windows 10(win insider build 18282). Using a straight HDMI cable doing HDMI to HDMI I do get the HDR option.

I have tried both the current graphics driver and the latest 6373 and there is no difference in behavior, Bios and all other drivers are the latest version.

I also have installed the 33 upgrade to thunderbolt. It's not a huge issue since there is not a lot of HDR stuff out there and I can use a straight HDMI connection.

I'm just curious if I'm missing something obvious and if someone else has got HDR to work on the TB Port.

Plugging in "Samsung MUF-128AB/AM FIT Plus 128GB USB 3.1 Flash Drive" to Front USB 3.1 Gen 2 is not stable

System: NUC8i7HVK, with Windows 10, 1803

 

When I plug a USB 3.1 drive into the 3.1 port on the front, it works for a while, and then a message pops up in Windows 10 saying "unknown device". So I go to device manager and it says:

 

Universal Serial Bus controllers > Unknown USB Device (Device Descriptor Request Failed)

 

So I have to uninstall the driver, and reboot, to get it working again.

 

If I plug it into the 3.0  port on the front, it's stable.

 

Anything I can do?

 

Thanks.

NUC7PJYH - No signal on Samsung 4K TV when HDMI UHD Color is ON

$
0
0

When I turn on "HDMI UHD Color" for the input to which the NUC is connected, TV says "No Signal".  HDMI UHD Color is needed for 3840x2160 @ 60Hz with 4:4:4 chroma and presumably configures the HDMI port as 2.0. When the PC boots - no splash screen, no BIOS (after pressing F2). 

 

If "HDMI UHD Color" is OFF, everything is fine, splash screen appears, and then BIOS (if I press F2). TV reports 3840x2160 @ 30Hz and the splash screen is apparently in 4K.

 

Similarly, in windows. When I switch to 60Hz (with "HDMI UHD Color" ON) I get black screen and then "No signal".

 

It looks like when the HDMI port on the TV is configured as 2.0, NUC sends it something, which the TV does not understand.

 

TV:  Samsung UE40MU6100 (similar US version: UN40MU6300).

Cable: AmazonBasics High-Speed HDMI Cable, 6 Feet or 3 feet - Meets the latest HDMI standards (4K Video at 60 Hz, 2160p, 48 bit/px color depth); supports bandwidth up to 18Gbps.

Teamviewer Show Black Screen function not working with NUC7i5DNKE

Hi,

we found out that the Teamviewer "Show Black Screen" function is not working with NUC7i5DNKE when the Intel Graphics driver is installed. When we uninstall the graphics driver, so that only the Microsoft Basic Display Adapter driver is installed, it works.

Details: Intel HD Graphics 620 - Driver version 24.20.100.6286

Teamviewer Version 14.0.13880

I've already contacted the Teamviewer support, they says it's an Intel issue.

 

please fix.

thank you

Just received NUC8i7HNK. Questions: fans and power/reset headers

$

It has fan headers of course. Just noticed it mentions them and the m.2 2280 modules. Plus, I remembered I usually saw m.2 drives with heatsinks that went on top, this has none.

Do I need to add any fans or anything to this? I put in the RAM and SSD, just wanna make sure b4 I boot up

 

Also. I ordered a remote PC start kit. I thought it merely plugged into USB to somehow turn it on. Upon opening it I saw connectors for the power and reset headers. Normally in a PC you'd have the front switches come into this, then this would plug into the headers.. So both work. I've looked at tech spec sheet. The power/reset(if it exists) headers do not seem to be accessible, at least not from the normal top section.

Am I correct? Can I access them to plug this in?

Alternatives? I don't really want to use the "wake" stuff as it has to be in sleep.. Not actually powered off.. To function.
