Hi all

 

We'd like to design a customized board which support 4GB DDR3 RAM.

We use it in Linux BSP 4.1.0, but it seems only 1GB and 2GB DDR3 codes we can refer .

Before I use 4G bits (1CS) *4,total memory is 2G bytes is ok for me.

The DDR3 is H5TQ4G63AFR.

Now my board total memory is 4G bytes, 4G bits (2CS) *8. Per  CS  is 4ps.

Unfortunately, we got error when we try to use DDR stress tester on 4GB ram board.

error is here:

Beginning stress test
loop: 1
DDR Freq: 528 MHz
t0.1: data is addr test
Address of failure: 0x90000000
Data was: 0x00000200
But pattern  should match address


We will attached my detail  log and my test tools.



How to design hardware about have eight ddr3 chips,4Gbits(per chip is 256MB*16)*8?



Any ideas can help me to solve this issues?

 

 

 

Thanks a lot.
