T2080rdb-pc non-ecc so-dimm

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!

Yours sincerely

OK, Thanks for your reply!

And the U-BOOT log and the SO-DIMM DDR3 datasheet see the attachments.

Expect your reply, thx.

In the provided SO-DIMM datasheet it is written:

● 204-pin Dual-in-line DDR3 memory module.
● JEDEC Standard with 1.5 V (±0.075 V) power supply
