Subject: Re: [gem5-users] DRAMCtrl parameters for DDR4_2400_8x8

Hi everyone,
DDR4 does have 16 banks, while DDR3 is a 8 bank devices, but the devices per 
rank are defined by the module (interface). I agree that for the 2400_8x8 
configuration there should be 8 devices per rank defined. I am in the process 
of fixing this. Thanks for drawing this to my attention.

Regards,
Wendy
