I read in a different forum the memory can operate at 1.35v or 1.5v but I am not aware what is the SPD programmed to by default. Did you try setting the memory up manually to 1.35v?
Thank you for your reply.
The memory configuration in BIOS is the following (presumably from SPD, since the memory settings are set to automatic):
- CLK 133MHz
- tCL 11
- tRCD 11
- tRP 11
- tRAS 28
- voltage 1.35
This is with a single module installed. Unfortunately I cannot see what it is when I put both modules in, since the NUC does not POST.
Do you know if you guys have the recommended timing configuration for this memory in dual module config? The memory page lists it as tested - would it be possible to get this information from the validation team?
I have exactly the same issue on my NUC, with the same RAM module (CT51264BF160BJ).
With only one RAM module it works (doesn't matter which one) but with both, it stay stuck with the 3 led blinking.
So if you have issue too, maybe it's not an hardware issue.
It seem to be the second slot which cause an issue, I have the 3 led blinking with only one RAM module ...
Please allow us more time to check on this.
Does I have to ask the site where I bought it for an exchange or you think it an firmware issue which it could be resolved with a new bios ?
I am facing the same exact issue. NUC5i3RHY & NUC5i5RHY + CT51264BF160BJ (bpstore order: 3 x core i3 , 1x core i5 , 4x Crucial Memory kit) + RY0137.BIO - can't get dual channel working with Crucial memory.
* Dual channel works fine with 2x KVR16LS11/8
* CT51264BF160BJ only works in single channel (slot closest to motherboard)
Based in Belgium and willing to test & assist to debug this issue – can make my setup available internally.
Edit: Dual channel also works with SKhynix HMT351s6efr8a-pb (not listed as officially supported)
Edit 2: CT51264BF160BJ works fine in dual channel on HSW NUC D3410WYK WY0035.BIO
Alright, thanks for testing and confirm the issue.
Hope you can move forward as fast as possible on this issue.
Any news about this issue ?
Exact same problem on my NUC5i5RYK as well. Will not boot when anything is plugged into the top memory slot. I'm using Crucial 4x2 GB (CT51264BF160BJ) memory. I am able to boot with the lower slot populated only.
We tested with CT51264BF160BJ.C8FER and this RAM works properly. You may need to check with RAM manufacturer if this part number is the same or if it complies with SDRAM density and organization listed in Technical Product Specification (page 19).
Please check: The specified item was not found.
The modules I've got have C8FND extension - CT51264BF160BJ.C8FND. Which means the memory I have is useless. I believe I have been misled by the original memory compatibility list - what recourse do I have available?
Exact same situation here as well. I would also like to know what Intel plans to do about this. I now have $100 worth of useless ram..
I'm in the same boat as well. When I bought the memory, the compatibility list didn't specify that there were variations of this model that are not compatible.
I have same issue with NUC515RYH and Crucial CT51264bf160BJ.C8FND. Either DIMM will work alone in lower slot. If either is moved alone to upper slot, or if both are installed it fails to boot with 3 blinks. Seems like we need a new BIOS or a new manual setting from Intel to make these DIMMS work.
I bought both the NUC and the DIMMS from the Intel EPP store.
Only difference I can find in the .C8FND vs .C8FER is one is code for single 4Gbx1 DIMM and other is code for Dual 4Gbx2 DIMM Kit from Crucial.
Has anyone been able to make these DIMMS work with another setting.
