Overview
The Crucial CT2K64G56C46S5 is a 128GB DDR5 memory kit consisting of two 64GB SO-DIMM modules. It is designed for compatible laptops and compact systems that support high-capacity DDR5 SO-DIMM memory.
Operating at 5600 MT/s with a CAS latency of CL46, the kit provides memory capacity for demanding multitasking, professional applications, and memory-intensive workloads. Its 262-pin SO-DIMM form factor is intended for systems designed for this memory type rather than standard desktop DIMM slots.
The modules operate at 1.1 V and use an unbuffered, non-ECC configuration. Before purchasing, confirm that the system supports 64GB modules, a 128GB total memory configuration, and the required DDR5 speed. Actual operating speed depends on the processor and system specifications.
