channel 1 connect to 2 "MT41K512M16HA-125 AIT:A" & 1 "MT41K512M8RH-125-AAT:E" which is for ECC fuction

and channel 2 connect to 4 "MT41K512M8RH-125-AAT:E"

and let channel 2 to be float?

Hi Locust,
The two DDR channels are identical and independent. I see no reason why not use only channel 1.

Hi Stan

Thank you for the answer.

And should I change any software setting in bootloader or another place?

or I can just tear down the ddr on channel 2?

thank you
