Description
The Apple 661-7020 is a 2GB DDR3 Unbuffered DIMM (UDIMM) memory module engineered to enhance the performance of compatible Apple computers. With a clock speed of 1600MHz, it provides a significant boost in data transfer rates, allowing for smoother multitasking and faster application loading. The 1Rx8 configuration indicates a single-rank module with eight memory chips per rank, which is a common and efficient design for many desktop and workstation applications. This memory module adheres to the DDR3 standard, offering improved power efficiency and performance over previous DDR generations. The CL11 CAS Latency signifies the number of clock cycles it takes for the memory to respond to a request, and CL11 is a standard timing for 1600MHz DDR3 modules. Its UDIMM form factor means it is unbuffered, making it suitable for systems that do not require the additional signal buffering found in Registered DIMMs (RDIMMs). Specifically designed with Apple's hardware architecture in mind, the 661-7020 ensures seamless integration and optimal performance within supported Mac systems. Whether upgrading an existing system or building a new one, this memory module offers a reliable and cost-effective solution for increasing system responsiveness and handling more demanding workloads.
