FAQ's
What does ECC RDIMM mean in this Samsung memory? ECC RDIMM stands for Error-Correcting Code Registered DIMM. It detects and corrects memory errors and includes a register to improve signal integrity, commonly used in servers and workstations. Is the M393A2K40BB2-CTD7Q compatible with standard desktops? This module is designed for servers and workstations with ECC RDIMM support, and it is generally not compatible with standard desktop systems that use unbuffered DIMMs. What does the CL19 specification indicate? CL19 refers to the CAS Latency timing, indicating the number of clock cycles between a memory read command and when data is available. Here, it means a latency of 19 cycles at 2666 MHz. Can this memory be mixed with non-ECC modules? Mixing ECC RDIMMs with non-ECC modules is not supported as they use different signaling and error correction methods, which may cause system instability. What types of servers support this Samsung module? This memory is compatible with servers that accept DDR4-2666 ECC Registered DIMMs, typically from enterprise hardware vendors supporting ECC functionality. Does this module require specific BIOS settings? Systems using ECC RDIMM memory may require BIOS configuration to enable ECC features, but specific settings depend on the server or motherboard manufacturer.
