Question: what is the difference between ram types?
Answer: While DDR2 RAM has data transfer rates ranging from 400 to 1,066MT/s, DDR3 smashes this at 800-2,133MT/s. Voltage is another important aspect of RAM generations. DDR2 RAM uses 1.8V, while DDR3 is lower at 1.5V. Lower voltage means the RAM uses less power, thus putting less strain on the CPU.
