IP catalog EMIF DDR4 preset

Dear,

In Quartus16.0, I want to creat one DDR4 IP using IP catalog.

However, I found that when I use "DDR4-1600J CL10 Component 1CS 2Gb (512Mb x 4)" preset, the DQ width is 8 after I apply this preset.

Then I tried all the preset which has "x4" in the name, all the DQ width is 8 after applying the preset.

Is this right? Should DQ bitwidth be 4 in these kind of preset?

Brs,

Leon
