Boost your system's performance with the 4GB DDR3L 1600 MHz CL11 UDIMM Memory Module from Transcend. Delivering speeds up to 1600 MHz, this single-rank module is a plug-and-play memory upgrade designed to improve your computer's start-up times, overall responsiveness, and ability to handle data-intensive applications. It is non-ECC and unbuffered, features a CAS latency of CL11, and works on systems with a 240-pin DIMM slot and a DDR3-enabled chip. Moreover, it operates at a nominal voltage of only 1.35V, which not only produces less heat, but also reduces the electrical load on the memory controller to offer power savings of up to 15% versus standard 1.5V memory modules.
