Dear Engineers of NXP:


I am using the T2080RDB-PC board, and found a problem about the DDR.


I changed the DDR3 memory card(original=D3XP56082XL10AA)

with my laptop memory card(RMT3150ED58E8W1600).

Then, It doesn't work any more.


I have considered the 1.35V(DDR3L) and 1.5V(DDR3) , tried others laptop memory card(about five kinds of memory card), and get the same results.

I saw the register of DDR below, and it is fine!

I used the DDRv tool to validate them, and would't get the right value.


However, the original DDR3L works fine in 1066M/1333M/1600M/1866M, and could find the right value in DDRv tool.


I also tried the 4GB DDR3L laptop memory card, and It couldn't work too.


Theonly difference is that D3XP56082XL10AA support ECC and RMT3150ED58E8W1600 cann't support ECC...


Does the T2080RDB-PC only support the ECC memory card?Why my memory card can't work?


Looking forward to your reply, and Best wishes to you!
