Good speed

Speed of the computer has improved dramatically

Aggressive DesignIt is one of the DDR3 memory for laptop that provides overclocking faster speeds than any other in its class

Excellent memory modules that have provided great speed and reliability on my 2015 iMac

Great RAM, fast speed, favorite brand.
