No display on new Intel NUC6CAYH

Hi,

I got my NUC (NUC6CAYH) today and was very excited until I found out there is no video output. Below are what I put in the NUC:

- 1x Crucial 4GB 204-Pin SODIMM DDR3 PC3-14900 1866 MT/s Memory Module from https://www.bhphotovideo.com/c/product/1121857-REG/crucial_ct51264bf186dj_4gb_204pin_sodimm_ddr3.htm... B&H Photo Video

- 256GB SSD

- USB flash drive with Ubuntu 16.04

I tried to connect a 1080p monitor with both VGA and HDMI. Neither of them gave display on the screen. The screen was tested with other computer and it worked fine. I tried to use the upper RAM slot and lower RAM slot, and neither of them worked. The blue power button light was on after I pressed it to power on and there was no blinking/flashing on the power button light during start up. I was able to reboot the machine once with "Ctrl+Alt+Del" and saw the power light went off and then on.

Can some one explain me what else I should try to bring out the display?

If nothing work, should I contact Intel or the seller (B&H) for refund/replacement?

Thanks in advance!

Xin

The NUC6CAYH requires DDR3L (i.e. 1.35V) memory. It will not work with regular DDR3 (1.5V) memory.

Thanks for your reply. But from the specification of this RAM, I can see that this RAM is 1.35V. I can also see 1.35V written on the label on the RAM.

Please provide full part number for the SODIMM.

Here is the number I found on its box: CT51264BF186DJ. It also appears on the product's website: https://www.bhphotovideo.com/c/product/1121857-REG/crucial_ct51264bf186dj_4gb_204pin_sodimm_ddr3.htm... B&H Photo Video , which is where I bought it.

Hhmmm...

All of the memory that I have used is specifically DDR3L. I have not played with any of the DDR3 DIMMs that claim they work at 1.35V (but this is not the first time I have seen someone mention it).

My other concern is that the AY NUC is spec'ed for 1600MHz memory, not 1833MHz.

Let's look at some other possibilities: How are you connecting the monitor? HDMI? DP? VGA? DVI? Are you using a conversion dongle or a straight through cable?

Thanks for the response. Before I bought this 1866MHz 1.35V RAM, I have carefully I checked the specifications of this NUC and its CPU to make sure they are compatible with this RAM.

I tried HDMI cable and VGA cable. No converter/adapter were connected to the cable, so signals should go straight through them. The HDMI cable has being successfully transmitting 4K video from other PC, so I think it supports HDMI 2.0.

Hi Scott,

This time I must not agree with you for the following reasons:

1. The CT51264BF186DJ is DDR3L type as indicated on Crucial data sheet: http://www.crucial.com/usa/en/ct51264bf186dj# productDetails Crucial 4GB DDR3L-1866 SODIMM | CT51264BF186DJ | Crucial.com and is rated for

 

1.35 V.

2. The 1886MHz memory is supported for this NUC - see Intel page:https://www.intel.com/content/www/us/en/support/articles/000023025/boards-and-kits.html System Memory for Intel® NUC Kits NUC6CAYH and NUC6CAYS Same definition in Product Specification para. 1.4 https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/NUC6CAYS_NUC6CAYH_TechProdSp... https://www.intel.com/content/dam/support/us/en/documents/boardsandkits/NUC6CAYS_NUC6CAYH_TechProdSp...

I don't know why this memory is not working. Any way Crucial on there page gives list of compatible memory for NUC6CAYH: http://www.crucial.com/usa/en/compatible-upgrade-for/Intel/nuc6cayh# memoryResults RAM & SSD Upgrades | Intel NUC6CAYH | Crucial.com . On this page you can find a memory P/N CT9932630 very similar to CT51264BF186DJ , tested to be compatible with this NUC.

I suggest to ask Crucial what is the difference between those two parts.

Regards

Leon

Hello evantong623

I understand that you don't see any video output (including the Intel logo and F2,F7,F10 menu during boot). The problem can be with your memory as you suspect (failed or not compatible) or some bios corruption. In order to find if the problem is in bios, follow the following steps:

1. Disconnect the power adapter and remove the bottom cover from your NUC.

2. Remove the yellow security jumper and close the bottom cover.

3. Reconnect the power adapter and power On the NUC. Wait 30 sec - 2min. If the memory, cable and monitor are working you shall see the Configuration Menu - similar to the attached image.

4. If you see this menu, insert and USB stick (prepared before) with the latest bios file - AY0041.bio downloaded from here: https://downloadcenter.intel.com/download/27088/BIOS-Update-AYAPLCEL-86A-?product=95062 Download BIOS Update [AYAPLCEL.86A]

5. Press F4 and the bios recovery will start after some time and will end after 2 -5 minutes.

6. When bios recovery completed, switch the power OFF, remove the power adapter and replace the Security Jumper.

Hope this will help

Leon,

As I have said before, it really doesn't matter what is listed on the compatibility list. Something appearing there just means that one particular set of DIMMs happened to work in one particular test with one particular NUC of that model. This does not mean that it will work in all NUCs of that model. Any time that you run memory at above-rated speeds, you could have issues. The problem is noise. Noise can - and will - differ from one individual unit to another and noise is amplified by faster bus speeds. I won't go into details here regarding all the myriad sources and causes of noise; it would take way, way too long and accomplish nothing. Secondly, BIOS mods (in some cases) to stop the overclocking of the memory busses is not going to avoid all issues; not all DIMMs work (as) well at speeds other than their rated speed (even those lower). My bottom line message remains consistent: I never, ever recommend the use of memory of above-rated speed.

Only the paranoid survive!

lw1948, Thank you so much for looking up the model specifications and compatibilities, as well as providing the solution! , thank you for explaining your ideas in detail.

I tried exactly what suggested. However, there is still no video output, i.e. no menu as in his picture. I guess it may not the BIOS issue then? I realized that the NUC is extremely quite all the time. Is it usual? I wonder whether its CPU fan is stuck.

I wish I know the webpage that has all the recommended RAM earlier. I think what I can do now is to return the 1866MHz RAM and buy the Crucial 4GB DDR3L-1600 SODIMM (CT51264BF160BJ). What do you guys think?

I think that that is prudent.

When picking the DIMM(s) to purchase, remember that the AY NUC cannot support 1Gb/2Gb SDRAM densities; the density needs to be 4Gb or higher. Consult this page for more information: https://www-ssl.intel.com/content/www/us/en/support/articles/000023485/boards-and-kits/intel-nuc-kit... Unsupported 1Gb or 2Gb Density Error for Intel® NUC NUC6CAY.

The CT51264BF160BJ shall be OK. Please read the following thread:

Hope this helps

lw1948, N.Scott.Pearson. Thank you both for the previous suggestions. I got my new RAM, the CT51264BF160BJ. But there is still no display. I guess this NUC is defective and I may have to return this NUC. What do you guys think?

Hello evantong623

I agree with you. You have try all the steps in order to get at least the basic video output (i.e. Intel logo, boot menu or Bios settings) from your NUC. It is time to return this NUC.

Yea, I can't think of anything else to try.

Unless you can get the unit replaced where you bought it, you will need to contact Intel Customer Support directly to set up the RMA. Here is contact information based upon geography:

http://www.intel.com/content/www/us/en/support/contact-support.html# @11 Intel Customer Support Contact Information for US and Canada

http://www.intel.com/content/www/us/en/support/contact-support/emea-contact.html Intel Customer Support Contact Information for Europe, Middle East and Africa

http://www.intel.com/content/www/us/en/support/contact-support/apac-contact.html Intel Customer Support Contact Information for Asia-Pacific

http://www.intel.la/content/www/xl/es/support/contact-support/lar-contact.html Intel Customer Support Contact Information for Latin Americahttp://intelsupportchat.force.com/icslivechat/ics_tech_desktop_ww_english_Chat

 

You can also try using the Chat service (here: http://intelsupportchat.force.com/icslivechat/ics_tech_desktop_ww_english_Chat Intel Customer Support Chat Service), but this only works during specific hours.

If you use the RMA service, remember to remove your drives and memory from the unit before you send it back. Also, in most cases, they only send you the (replacement) base unit, so keep your power adapter as well.
