DDR4 HiLo in Stratix 10 MX

Hello there, We recently acquired a new Stratix 10 MX devkit - 1SM21BHU2F53E1VG. I am currently testing different interfaces of the device using the Board Test System (BTS) that is provided by I...

    HI,


    I have consulted both Intel marketing and Intel Engineering team regarding your issue


    The feedback that I got is typically as long as the HILO card is firmly inserted into the board slot then should be fine. Else if there is loose pin contact then user may encounter DDR4 calibration failure.

    • I recalled you told me you have verified that your HILO card is properly/tightly plug into on board HILO connector, right ?


    For DDR4 Hilo card replacement, Intel marketing commented can directly ship DDR4 hilo replacement card to you.

    • Can you share with me your shipment detail ?
    • Shipment attention name, address, phone contact and email contact
    • You can use forum private message function to share with me shipment detail if you don't feel comfortable to share detail in this public forum post


    Thanks.


    Regards,

Hi,


Based on my understanding, the 8GB vs 16GB memory density difference is applicable to HBM2 memory, not DDR4 Hilo memory density.


You can see the difference in ordering info table. The FPGA OPN is difference as well


The board that I am using is same like yours which is 1SM21BHU2F53E1VG (8GB HBM2)


Can you provide me your S10 MX dev kit board serial number so that I can validate whether your board is still under warranty claim ?


In parallel, I will find out further within Intel internally on the RMA claim process as well.


Thanks.


Regards,

dlim

Hello @Deshi_Intel ,

Yes - you are correct regarding the difference between the two boards. However, when I looked at the HiLo example designs for each of the board, the EMIF is parameterized as UDIMM in the 16GB HBM2, and COMPONENT in the 8GB HBM2. Since the DDR4 Hilo is not different in the two boards, I was confused (and curious) about which design you used for your test.

Since you are using the same board as me, I guess your EMIF is parameterized as COMPONENT.

For your reference, my board's serial number is 10SMXPCIe000398 and K54160-001. I should mention that the board works well: all the designs we have tested on it so far have passed. It is just the HiLo design that is failing in the calibration stage. This could point to a problem with the design and/or the daughter card.

Could I ask you what the DDR4 HiLo card you are using?
The FBGA and Component Marking in my daughter card is 7LB45 D9TNZ (which according to https://www.micron.com/support/tools-and-utilities/fbga tells me the part number).

Thanks again for the help and support you are providing to resolve this issue.
