What is DDR3 1333 RAM?

An essential hardware component of any desktop or laptop computer, memory or RAM is where data is temporarily stored and accessed by programs that are running. DDR3 SDRAM is just one type of memory, defined by the coordination and frequency of its interfacing. Kingston is one brand of electronics manufacturer that offers a range DDR3 memory.

What Are Important Details to Know When Inserting Memory?

When adding or replacing memory in your laptop or desktop computer, there are some details worth understanding so that you make sure youve got the right memory for your computer. Details you should know include:

• Memory Modules: The term modules refers to memory boards like DIMMs, SODIMMs, SO-DIMMs that fit into slots on a computers motherboard. Memory is often described as the combined capacity of a group of modules, so 8 GB RAM may be made up of four 2 GB DIMMs.
• Compatibility: Motherboards are only able to fit certain types of memory based on their specifications. This is regulated by the number of pins and the placement of a notch on the card, so that the wrong type of memory cant be installed by mistake. This means that a motherboard compatible with DDR3 240-pin DIMMs wont take a DDR4 board as it features a 288-pin DIMM design and not the required 240-pin design.
• Transfer Rate and Bandwidth: Two important factors of a memory module can be determined from the name of the module, maximum transfer rate and bandwidth. For instance with a Kingston DDR3 1333 PC3-10600 DIMM, chips on the memory module have a maximum data transfer rate of 1333 MHz and the module has a maximum bandwidth of 10660 Mbps.

What Are the Features of DDR3 SDRAM?

To understand what DDR3 is and what the benefits of using it are, its useful to detail its characteristic features, such as:

• SDRAM Memory: Unlike regular RAM, DDR3 memory operates on synchronous dynamic RAM (SDRAM) which is defined by its reliance on an external clock signal to provide the timing of interface transfers to the computers processor. The benefit of SDRAM is that with a shared clock signal, the processor is never waiting unnecessarily for transfers from the RAM memory.
• Double Data Rate: DDR3 stands for the third version of the double data rate interface, which benefits from increased bandwidth because it transfers data twice per clock cycle rather than just once.
• CAS Latency: One attribute of DDR3 memory that can change between models and manufacturers is the CAS latency, a measure of how long between the command for access and the availability of a the requested memory column. The latency is measured in the number of clock ticks and represented as CL9.
