Intel NUC6CAYH trouble with RAM density

Jump to solution

I recently bought BOXNUC6CAYH with two Kingston KVR16LS11/4 (4Gb each) validated by Intel as suitable for this PC. But when starting the system "Unsupported 1Gb / 2Gb density SODIMM(s) detected on SODIMM Slot 2. System instability or data loss possible. Replace with SODIMMs with 4Gb or higher density. Continue (Y/N)." is shown.

 

In BIOS both are recognized as 8Gb. I could instal Ubuntu and everything went OK, but lately weird things began to happen with some software.

 

Thanks for your help!

Hi Pedro,

Still I would say that not necessarily the NUC is faulty. Few times I saw that the SO DIMM where wrongly labeled. Please count how many DRAM elements (chips) are located on each site of your memory module? Better, if you can, please attach images of both sides of this SO DIMM.

Please replace the SO DIMMs in place (i.e. the SO DIMM installed now in slot 1, please install in slot 2 and vice versa). If you will get the same error (i.e error in Slot 2) it means that your NUC is faulty. However if now the error will indicate wrong density in Slot 1 - you should replace this SO DIMM.

Thanks for your response Leon. But I just realised error was "Unsupported 1Gb / 2Gb density SODIMM(s) detected on both SODIMM Slots. System instability or data loss possible. Replace with SODIMMs with 4Gb or higher density. Continue (Y/N)." I copied the previous error by mistake. I'm sorry.

 

I have not extra DIMMs to try out but I tried to switch the ones I own in different slots and it doesn't work. Also, I kept just one RAM in main slot and issue remains.

I guess the problem would be with the NUC more than both DIMMS are faulty.

 

Thanks again.

Hi again Leon,

 

you are right! 😓 It turns out that this memory module (KVR16LS11/4) is listed as valid. I bought them from Amazon where I counted 4 modules in pictures, but when I read you yesterday I realised it was configured by 8 chips each side, so it's listed INCOMPATIBLE.

 

I think Kignston should categorize more specifically considering the number of chips in order to avoid this kind of misunderstandings.

 

Best regards and thanks for your help.

Hi Pedro,

Kingston is O.K. Happens what I saw already few times. You got wrong labeled module. The KVR16LS11/4 is compatible since it is build from 8 chips ( 4 on each side). See the data sheet https://www.kingston.com/datasheets/kvr16ls11_4.pdf . You should return your SO DIMMs.
