What is DDR3 Memory?

DDR3 SDRAM or Double Data Rate Three Synchronous Dynamic Random Access Memory is a random access memory interface used in computers and other electronic devices.
  • DDR3 components are twice as fast as today's highest speed DDR2 memory products.
  • DDR3 provides higher bandwidth and increased performance at low power.
  • DDR3 has data rates of 1066 to1600 MT/s and clock frequencies of 533 to 800MHz
  • DDR3's standard 1.5V supply voltage cuts power consumption by up to 30% over DDR2.

DDR3 FAQs

Is DDR3 RAM Memory backward compatible with DDR2?

No. DDR3 memory chips and modules are very different from DDR2. For example, DDR3 runs at a lower voltage (1.5V) than DDR2 (1.8V).

Can DDR3 DIMMs be plugged into DDR2 sockets or vice versa?

No. Memory modules (Unbuffered, Registered, Small Outline DIMMs) have a special “key” or notch in their connector. These keys must align with a key in the memory socket to allow the module to be inserted. All DDR3 and DDR2 module types are keyed differently. DD

How do I correctly install a DDR3 Memory Module?

Before touching these modules, ensure that you are correctly grounded.  Before inserting module to motherboard or machine make sure that motherboard or machine is correctly grounded. This can be done by wearing some kind of static control device such as a wrist strap or foot straps. Machines can be grounded by connect the power cable to a power socket (that is turned off).
Pick up the module by it’s sides. Do not touch the gold contacts at the bottom of the module. Look at the notches at the base of the module and line them up with the notches on the connector of the DDR3 motherboard.  Press the module into position, making sure that the module is properly seated in the connector. The tabs on the sides of connector will snap into place by hooking into the sides of the module.
