FAQ's
What does ECC mean in this memory module? ECC stands for Error Correcting Code, which helps detect and correct single-bit memory errors to maintain data integrity in critical systems. Is this memory compatible with standard desktops? This module is a Registered DIMM (RDIMM), typically compatible with servers and workstations, not standard desktop PCs which generally use unbuffered DIMMs. What is the significance of DDR4-2666 in this product? DDR4-2666 refers to the memory's data transfer rate of 2666 MT/s, indicating its communication speed with the system. What does CL19 indicate for this RAM module? CL19 specifies the CAS latency, meaning the delay of 19 clock cycles between memory request and data availability. Can this RDIMM be mixed with non-registered memory? Generally, RDIMMs like this one should not be mixed with non-registered (UDIMM) modules as they have different signaling and electrical characteristics. Which systems typically use Samsung M393A1K43BB1-CTD7Y memory? This memory is designed for servers and workstations that require ECC registered DIMMs for enhanced stability and error correction.
