DDR3 SO-DIMM 16G - Calibration fail (external memory interface toolkit) why are the CK signals N/A in the report (ref attached file)

HI,

mem_CK is the reference clock used to calibrate other DDR3 signal but we don't calibrate mem_CK signal itself.

That's why you see the report shown CK as n/a

Thanks.
