The "C" in CUDIMM stands for "Clocked," indicating the presence of a Clock Driver (CKD) on the module. The CKD regenerates and amplifies the clock signal from the host, ensuring clean, synchronized timing across all DRAM components. SMART's CUDIMMs specifically include a CKD to deliver precise timing to each DRAM, improving signal integrity and enabling speeds up to 6400 MT/s. These modules maintain the low-latency benefits of unbuffered memory and are ideal for high-performance embedded, telecom, and networking applications.
