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 (1):
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. DDR3L is a dual voltage capable memory SoDIMM, which supports operation at both 1.5V and 1.35V. DDR3L is also pin-compatible with DDR3. DDR3 is a single voltage capable memory SoDIMM, which supports 1.5V operation only.
example (2):
PC3L-12800S DDR3 1600MHz 204pin So-Dimm
Low voltage DDR3 ram
