What do the RAM specs mean?
Part of Lesson Plan: Introduction to Memory- What is RAM?
Activity Overview / Details
Switch back to the image of the RAM chips and the specs: 2x2 4GB - DIMM 240-pin - DDR3 - 10.66 MHz / PC3-8500. Take each specification and discuss its meaning.
2 x 2 4GB = 2 modules 2GB each that make a 4GB pair
DIMM 240 pin = Dual Inline Memory Module with 240 total pins
DDR3 = Double Data Rate 3. Higher bandwidth (up to 1600 mb/s) than DDR2 at low power consumption (1.5 volts)
10.66 mHz/PC3-8500 =
