Hi,
I am using Micron MTK512M16HA-125 DDR3-1600 DRAM ( 1x 4 gigabyte) on my custom board .When I try settings which shown below with 64 bit bus width , DDR stress test program ( NXP DDR Stress Tool v2.92 ) fails calibration and card's cpu freezes.
Is there any wrong configuration on my settings ?
Thanks for help ,

Hello,
i.MX6 memory frequency is about 533 MHz, therefore it makes sense to try
using DDR3-1066 specs. You may try tRC = 52.5 ns; tRAS=37.5 ns.
Also, please check if Your PCB design satisfies recommendations of the
HW_Design_Checking_List_for_i.MX6DQP6DQ6SDL:
HW_Design_Checking_List_for_i.MX6DQP6DQ6SDL
In particular use the sheet, named "MX6 DRAM Bus Length Check".
Have a great day,
Yuri
