 127         cycles) and 6 quarter-cycles (1.5 cycles) for 3 other lanes.
 128         The default value 0 means autodetection. The results of hardware
 129         autodetection are not very reliable and depend on the chip
 130         temperature (sometimes producing different results on cold start
 131         and warm reboot). But the accuracy of hardware autodetection
 132         is usually good enough, unless running at really high DRAM
 133         clocks speeds (up to 600MHz). If unsure, keep as 0.
