  93         means that the delay is 5 quarter-cycles for one lane (1.25
  94         cycles) and 6 quarter-cycles (1.5 cycles) for 3 other lanes.
  95         The default value 0 means autodetection. The results of hardware
  96         autodetection are not very reliable and depend on the chip
  97         temperature (sometimes producing different results on cold start
  98         and warm reboot). But the accuracy of hardware autodetection
  99         is usually good enough, unless running at really high DRAM
 100         clocks speeds (up to 600MHz). If unsure, keep as 0.
