FAQ's
What does ECC RDIMM mean for this memory module? ECC RDIMM stands for Error-Correcting Code Registered Dual Inline Memory Module, which means it can detect and correct certain types of memory errors and has a register to improve signal integrity in servers. Is the Samsung M393A2K43BB1-CTD7Q compatible with standard desktop PCs? This module is designed for servers and workstations using registered ECC memory and is generally not compatible with standard desktop PCs, which use unbuffered non-ECC memory. What does the 2666 speed indicate? The 2666 MT/s speed indicates the maximum data transfer rate of the module, specifying it can transfer 2666 million data cycles per second, affecting overall memory throughput. What is the significance of CAS latency 19? CAS latency 19 indicates the number of clock cycles between a memory request and when data is available, which affects memory access timing but should be considered along with other specs. Can this module be mixed with other DDR4 memory types? Mixing different DDR4 memory types, especially ECC registered with unbuffered or non-ECC modules, is generally not supported and can cause system instability. Does this memory require special motherboard support? Yes, the motherboard must support ECC registered DDR4 modules to properly utilize this memory and its error-correcting features.
