DDR3 is the next generation of Double Data Rate (DDR) Synchronous Dynamic Random Access Memory (SDRAM). It is an evolution of DDR and DDR2 memory technology that delivers higher speeds (at launch up to 1066MHz for ValueRAM® memory, beyond 1333MHz for HyperX® memory), lower power consumption and heat dissipation.

Intel chipset-based desktops in the first half of 2007 and then notebook and server platforms to follow in 2008 and 2009. Kingston engineers are working closely with Intel to ensure best compatibility ValueRAM desktop, notebook, workstation and server memory.

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).

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.

It is difficult to distinguish a DDR3 motherboard from a DDR2 motherboard just by looking at it. Inserting a DDR3 DIMM into a DDR2 motherboard could damage the module, the motherboard, or both To prevent such damage, the simplest process is to align the memory module and the socket, and visually check that the module “key” aligns perfectly with the socket key. You may have to turn over the memory module as the memory module direction may misalign even compatible socket and module keys.
