In short, 204-pin small outline dual inline memory modules (SODIMMs) are the form factor used to provide DDR3 memory modules for notebook computers and other small form factor computing platforms. 204-pin SODIMMs are currently available in PC3-8500 (DDR3 1066MHz) and PC3-10600 (DDR3 1333MHz) speeds.Increases system performance .
Easy to install .
Premium quality memory from a trusted brand .
DDR3 & DDR3L are the same thing (DDR3L stands for DDR3 Low voltage and applies to our 1.35V DRAM) .
This is a dual voltage piece and can operate at 1.35V or 1.5V .
