FAQ's
What does ECC mean in this memory module? ECC stands for Error-Correcting Code, which detects and corrects single-bit memory errors to improve data integrity, making it suitable for servers and critical systems. Is the Samsung M393A2K40BB2-CTD7Y compatible with standard desktop motherboards? This module is a registered DIMM designed for servers and workstations, so it is generally not compatible with standard desktop motherboards that use unbuffered DIMMs. What is the significance of CL19 in this memory? CL19 refers to the CAS latency, which is the delay time between a command and data availability. A CL19 latency indicates the timing characteristic of this DDR4-2666 memory module. Can this memory module be mixed with non-ECC RAM? Mixing ECC registered DIMMs with non-ECC memory is typically not supported and can lead to system instability or failure to boot. What type of systems use registered DIMM memory? Registered DIMMs like this one are primarily used in servers and workstations designed to handle higher memory capacities with improved signal integrity. Does this memory require specific motherboard support? Yes, this ECC registered DIMM requires a motherboard and processor that support DDR4 ECC registered memory modules.
