NUC7PJYH Samsung M471A5244BB0-CRC Dual-channel ?

I am using NUC7PJYH BIOS Version 0039 - JYGLKCPX.86A.0039.2018.0528.1436

I have a question

Samsung M471A5244BB0-CRC http://www.samsung.com/semiconductor/dram/module/M471A5244BB0-CRC/ M471A5244BB0-CRC | Samsung Semiconductor Global Website

I attach two pieces and operate it but the operation speed of the memory is slow. Are you moving on a single channel?

Memory tested Dual-channel operation confirmed in other environments

M471A5244BB0-CRC I realized that Intel has not been tested http://compatibleproducts.intel.com/ProductDetails/ExportPeripheralInfo?moduleName=Intel®%20NUC&productType=Kits&productName=Intel®%20NUC%20Kit%20NUC7PJYH&_ga=2.169743905.1872206161.1528248684-173274131.1527993622 Intel® Product Compatibility Tool

Hello Uz,

 

Thank you for contacting us regarding the memory compatibility for your Intel® NUC NUC7PJYH

 

We performed a comparison between the specs of the unit that you own (Samsung* M471 A 5244 BB 0 – CRC) and the memory system requirements for your Intel® NUC NUC7PJYH.

 

Essentially and at first sight, the unit meets all the requirements specified under the page 17, art.1.4 (System Memory) of your Intel® NUC NUC7PJYH specifications sheet:

 

https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC7xJY_TechProdSpec.pdf https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC7xJY_TechProdSpec.pdf

 

As you may know the Samsung* M471 A 5244 BB 0 – CRC is not displayed under our list of tested peripherals, and that lead us to think that there might be a feature that is not specified by the memory manufacturer, that may affect the performance of the NUC so we cannot guarantee full performance if the memory has not been validated by Intel®.

 

We strongly encourage you to contact Samsung* so they can take the guide provided above as a reference to provide you support on this matter.

 

In order to answer your question, yes, your Intel® NUC NUC7PJYH supports Dual Channel.As well we would like to know what kind of test or software you are running in order to measure the memory's performance.

 

 

I hope to hear from you soon.

 

 

Best regards.

 

Diego S.

Wait, this specific memory is 1Rx16. I thought 1Rx8 was part of the requirements???

I think that this memory module meets the NUC7PJYH requirements. This module is 4GB module, build from 4 * 1GB(8Gbits) SDRAM devices (i.e. the SDRAM density is 8Gbits).

The memory working mode can be tested with different applications. For example CPU-Z:https://www.cpuid.com/softwares/cpu-z.html https://www.cpuid.com/softwares/cpu-z.html or HwiNFO: https://www.hwinfo.com/download.php https://www.hwinfo.com/download.php

Is your Bios set to default settings? If not, please set it to default:

1. Enter Bios settings by pressing F2 during boot.

2. Press F9 (confirmed by "Y") to set default settings.

3. Press F10 followed by "Y" to save the settings and exit to Windows.

Check the memory performance.

From the data you supplied, I can see that the memory has correct density (8Gbits), however is not working as suppose to work. Can you borrow other memory module?

I am testing with the default Bios setting

It is difficult to confirm with other manufacturer's memory

Thanks Leon

Hello Uz ,

I understand that your main complain is that your NUC is not working in dual channel memory mode. However can you test each memory module separately? I intend to check performance of one memory module at time, first installed in bottom slot and than moved to the upper slot. After performing 2 tests with the first module, repeat the tests with the second memory module. The results from the all test should be the same.

I tried various tests.

Speed measurement with 1 Memory Memory slot on the same lower side

1st sheet 6174 MB / s

2nd sheet 6277 MB / s

M471 A 5244 BB 0 - CRC is the same lot

2 sheets Built-in operation time 7570 MB / s

Speed has risen It is unknown whether this is the correct speed of Dual-channel

Sorry, I really don't understand what are the results? Do you mean that when the memory is tested in lower slot, one module runs at 6174 MB/s and the other module runs at 6277 MB/s. What abut the speed of the memory modules in the upper slot?

Any way, you have to understand that in order to have computer working in dual channel mode you should have both memory modules with the same performances. This is the reason that to assure this a manufacture prepares modules kits, tested to have the same performance, like for example this one: https://www.amazon.com/Kingston-HyperX-2133MHz-Non-ECC-HX421C14FBK2/dp/B00TY6A1P0/ref=sr_1_4?s=elect... https://www.amazon.com/Kingston-HyperX-2133MHz-Non-ECC-HX421C14FBK2/dp/B00TY6A1P0/ref=sr_1_4?s=elect...

Having two memory modules with same P/N not always assure that they will work in dual channel mode.

As I've explain you, in my previous post you can use CPU-Z to check the working mode. See the attached image from my computer.

You are using (1) 8GB DIMM or (2) 4GB DIMMs, correct? JY only officially supports 8GB of memory total.

M471A5244BB0-CRC is 4GB module so, Uz is using (2) 4GB SODIMMs.

I have two 4 GB modules of Crucial CT4G4SFS824A memory installed (Intel tested for the NUC7PJYH), and I have not found any software that confirms that it is operating in dual channel mode. Pretty much everything in the memory tab of CPU-Z is greyed out, HWiINFO64 has nothing in the mode box, AIDA64 Extreme reports Type Dual Channel (128 bit) but Active Mode Single Channel (64 bit) and there is nothing in the bios to indicate whether the 8 GB of memory is operating in single channel or dual channel mode.

Has anyone been able to confirm operation of dual channel memory in the NUC7PJYH?

Please see the attached images of CPU-Z and HWiNFO64 and see where the memory mode can be verify.

Thanks. I know how to verify memory mode with CPU-Z and HWiNFO64. As posted previously, neither of these applications has been able to confirm that the NUC7PJYH is operating in dual channel mode.

Are the images that you posted from a NUC7PJYH? The installed memory of 2x8 GB would suggest not, although there have been reports that the NUC7PJYH can operate more than its specified maximum of 8 GB total memory.

Indeed, the attached images are taken from my NUC (NUC6i5SYH). Technical Product Specification of my NUC (para.1.4) specifies that this NUC is equipped with two independent memory channels with interleaved mode support (i.e.double channel support). However Technical Product Specification of NUC7PJYH (para.1.4) specifies only "Two memory channels". So, looks that you are right and this NUC can't work in dual channel mode.

Thanks for that clarification. Neither CPU-Z or HWiINFO64 give any information about which memory mode the NUC7PJYH is operating at. The closest I could get to how the memory was operating was from AIDA64 Extreme which reports Type Dual Channel (128 bit) but Active Mode Single Channel (64 bit).

Samsung M471 A 524 4 BB 0 - CRC 4 GB x 2

Samsung M471 A 1 K 43 BB 1 - CRC 8 GB x 2

SanMax SMD 4 - S 16 G 48 M - 24 R - D (Micron DRAM JEDEC 100%) 8 GB x 2

I could not confirm the operation on the dual channel

Three types of notes MemTest 86 speed does not change almost

Intel's remarks

NUC 7 PJYH supports dual channel.

Mystery deepens

Diego S,

To reduce confusion and speculations, cold you, please, advise what kind of test or software you are running in order to measure the memory's performance and to verify that it is working in dual-channel mode.

Thank you,

Peter
