DIMM can be single side or double side, it has 64 bit data and 2 or 4 clock signals. We strongly
recommend choosing 4-clock SDRAM for its reliability
Tip: To identify 2-clock and 4-clock DIMM, you
may check if there are traces connected to the
golden finger pins 79 and 163 of the SDRAM. If
there are traces, the SDRAM is probably 4-clock;
otherwise, it is 2-clock.
Tip: To identify single-side or double-side DIMM,
check golden finger pin 114 and pin 129. If there are
traces connected to pin 114 and pin 129, the DIMM
is probably double-side; otherwise, it is single-side.
