Final answer:
The fastest DDR3 DIMM sold today is the DDR3-2133, operating at 2133 MHz.
Step-by-step explanation:
The fastest DDR3 DIMM currently available is the DDR3-2133, which operates at a clock speed of 2133 MHz.
DDR3 stands for Double Data Rate 3, and it is a type of random access memory (RAM) commonly used in computers. DIMM stands for Dual In-Line Memory Module, which is a type of memory module used in computers.
DDR3-2133 provides a higher data transfer rate compared to lower-speed DDR3 modules, allowing for faster data processing and improved overall system performance.
