Laptop Memory

• Types of Laptop Memory

Laptops rarely use the standard SIMM and DIMM memory modules used by non-portable machines. Instead, you may find:

DDR-200 100 10 100 200 2.5±0.2 PC-1600 1600 DDR-266 133 7.5 133 266 2.5±0.2 PC-2100 2100 DDR-333 166 6 166 333 2.5±0.2 PC-2700 2700 DDR-400 200 5 200 400 2.6±0.1 PC-3200 3200
