Your RAM is not compatible with your NUC as Al has mentioned in the post above. Your RAM working clock is 1333MHz and not as required 1600MHz or 1866MHz. See the following tables for tested and approved RAM modules:
Addition problem in your RAM is incompatible SDRAM density. See this explanation for the message you got: Unsupported 1Gb or 2Gb Density Error for Intel® NUC Kits NUC6CAYS and...
As you can see 2GB modules with 4 chips are compatible. Examining Crucial data page I see that your memory has 9-10 chips each:
Hope this answer your quastion

Also this memory is not compatible because of the density issue. See the following article: CT51264BF160B vs CT51264BF160BJ - [Solved] - Memory . The CT51264BF160BJ has the required density of 4GB. In order to avoid buying of incompatible memory try to buy tested memory. If you want have 8GB memory, you shall buy a kit of 2*4GB and not separate two 4 GB memory modules. Both memory modules have to be from kit selected in manufacture with the same characteristics. I'll give you an example of such kit that is listed in compatibility table. This link is not advertising and is given for example only. There are other vendors and suppliers with equivalent or better products: Crucial 8GB Kit (4GBx2) DDR3L 1600 MT/s (PC3L-12800) SR SODIMM 204-Pin - CT2KIT51264BF160BJ: Amazon.co.uk: Computers & A…

I have joined many others with the ram incompatible error at bootup. I have purchased Crucial CT2KIT51264BF160B 2x4GB. I now have read that the NUC requires 'J' on the end of the memory model number. I have already purchased 10 sets of RAM. I get the error message at bootup and I press Y to continue.
A few questions:
What harm will be done or risks do I take with pressing Y to continue? (Meaning if I go ahead and not plan to replace the RAM.)
How can I bypass or disable this error message at bootup? I don't want to press Y every time to boot.
You are required to have DDR3L memory, which runs at 1.35V. What you have is standard DDR3 memory, which requires 1.5V. Usually it won't work at all. If it does work, it likely won't continue to do so and could harm the NUC long term. You are going to have to return the memory and have it replaced.
As far as I know, there is no way to disable this message - well, other than by installing the correct type of memory.
RAM compatible - I am looking at the reference list by Intel for the NUC6CAYH.
Here is a compatible RAM entry:
Crucial 8GB 1600 MHz CT8G3S160BM Intel Validated
However, when I search for this particular RAM is shows up as, Memory for MAC. https://www.amazon.com/Crucial-Single-PC3-12800-SODIMM-204-Pin/dp/B008LTBLLY/ref=sr_1_1?ie=UTF8&qid=1511838073&sr=8-1&ke… I am a bit hesitant to buy RAM for a PC that is listed as Memory for MAC. Can anyone confirm this specific RAM can be installed and compatible for the NUC6CAYH?
What do you think a MAC is? At this level, it is just like any other Intel processor-based PC. What is important is that it is DDR3L-1600 memory (and thus runs at 1.35V) and it uses 4Mb or 8Mb technology DRAM ICs.
In my NUC6CAYS, which is running great, I am using Crucial 8GB module CT102464BF160B.M16FN. Here is its Amazon link: Crucial 8GB Single DDR3/DDR3L 1600 MT/S (PC3-12800) Unbuffered SODIMM 204-Pin Memory CT102464BF160B. The one that you listed is virtually identical; the technical details from Crucial list a combined model number "CT102464BF160B/CT8G3S160BM", so either one should be ok.
Hope this helps,
This is interesting that your single stick 8GB RAM works (is compatible) as I purchased the same model 2x4GB RAM (CT2KIT51264BF160B) and it was not compatible thus the reason I need to find compatible RAM. I find it odd that the same model RAM but 8GB stick works but not 2x4GB kit. You stated you have a NUC6CAYS which is the brother to the NUC6CAYH which I would assume RAM compatibility would be the same, perhaps not. The approved spec list from Intel states these 2 RAM modules are validated,
Crucial 4GB 1600 MHz CT51264BF160BJ Intel Validated Crucial 8GB 1600 MHz CT8G3S160BM Intel Validated
I looked by Crucial.com and ran their Memory Advisor for both NUC6CAYH and NUC6CAYS and I found different Crucial Memory for both NUCs. Per website for NUC6CAYH 8GB stick 1600 is CT9932611 (Crucial PN), for NUC6CAYS 8GB stick 1600 is CT9932703 (Crucial PN). There seems to be a slight difference between the two NUCs according to the RAM part numbers.
I'm nervous about purchasing memory that may be incompatible again so I am being extra cautious.
The board in the NUC6CAYS is identical to that in the NUC6CAYH. The only difference is that the board in the NUC6CAYS has an extra 32GB eMMC SSD soldered to it. The memory requirements are identical. I have no idea why Crucial would have different part numbers for each -- unless that isn't a part number but just a number identifying a particular NUC model (i.e. entry in their database?).
An 8GB SODIMM does not have enough room on it for the number of DRAM ICs it would take to reach 8GB using 1Gb or 2Gb technology ICs. The same is not the case for 4GB SODIMMs; there *is* enough room to fit enough 2Gb technology ICs to add up to 8GB. Bottom line, you gave to be more careful when choosing 4GB or smaller SODIMMs.
Hope this covers it,
Hello, not sure where to create this so I thought I'd ask in here.
I purchased the following DDR3L kit and I am still getting this same message??
- 8GB (2x4GB) DDR3L SODIMM kit
- 9-9-9-24 latency
- Voltage: 1.35V
- Pin Out: 204 Pin
Is there any way to turn off this annoying warning? It really makes no sense for Intel to basically stop the post because my ram isnt exactly the model intel prefers.
Sorry for the trouble. I got this same POST message when I purchased incompatible memory by mistake. I found no way to ignore this message. I tried to BIOS settings but could not find a way around this message. Each and everytime you start or restart, you will have to acknowledge this message. Only way to resolve is so purchase and install Intel validated memory. Refer to reply at the top of this forum post. Look at Intel Product Compatibility Products (Memory Modules) for you NUC unit. Purchase one of the models identified by Intel to be valid and to work without error.
I learned the hard way as well and had to return all 10 sets of memory purchased. Your memory that was purchased is low-density therefore the POST message.
What does low-density ram mean ? and where are the density requirements?
Man, it is one thing to suggest and recommend certain RAM for system stability. I get that, but let me decide whether I want to see a warning message or not. Why is it forced by default? How was this not an option for a consumer-level product?
Thanks for the quick reply.
