Numbers on back of RAM explained.

DDR4-3200 - 3200 refers to the clock frequency

SO-DIMM - Small Outline DIMM in laptops and small form factor computers

DDR - Double Data Rate

DDR3-1600 is also PC3-12800 - generation of the RAM and its transfer speed. DDR3-1600 RAM operates at 1600 MT/s or the same as PC3-12800 operates at 12800 MB/s

example:

PC3 10600S-9-11-F3

  • PC3 (same as DDR3)
  • 10600 (bandwidth in MB/s),
  • S (stands for SODIMM, it's RAM for laptops),
  • 9 (CAS latency).
  • 11 is the SPD Revision or a way the memory communicates to BIOS
  • F3 is the Gerber Revision or changes in the printed circuit board

If it says PC3L it can operate at 1.35V or 1.5V

L is for low voltage. Don't mix L and non-L. If the laptop requires L then use L.
