Memory Population Rules

Your computer uses 1066 MHz and 1333Mhz DDR3 unbuffered or registered ECC SDRAM memory. DDR3 SDRAM, or double-data-rate three synchronous
dynamic random access memory, is a random access memory technology. It is a part of the SDRAM family of technologies, which is one of many DRAM (dynamic
random access memory) implementations, and is an evolutionary improvement over its predecessor, DDR2 SDRAM.

The primary benefit of DDR3 SDRAM is its ability to run its I/O bus at four times the speed of the memory cells it contains, thus enabling faster bus speeds and
higher peak throughputs than earlier technologies. This is achieved at the cost of higher latency. Also, the DDR3 standard allows for chip capacities of 512
megabit to 8 gigabit, effectively enabling memory modules of maximum 16 gigabyte in size.

DDR3 memory comes with a promise of a power consumption reduction of 30% compared to current commercial DDR2 modules due to DDR3

voltage. This supply voltage works well with the 90 nm fabrication technology used for most DDR3 chips. Some manufacturers further propose to use "dual-
gate" transistors to reduce leakage of current.

The main benefit of DDR3 comes from the higher bandwidth made possible by DDR3
