FAQ's
What does ECC stand for on this memory module? ECC stands for Error Correcting Code, a feature that detects and corrects common data corruption in memory, improving system reliability especially in servers. Is the P18454-B21 compatible with standard desktop motherboards? This module is a Registered DIMM intended for server systems and is generally not compatible with standard desktop motherboards that use unbuffered memory. What is the significance of the 2933MHz speed rating? The 2933MHz rating specifies the operating frequency of the DDR4 memory, indicating the rate at which data is transferred, suitable for systems supporting this speed. What does CL21 latency mean for this memory? CL21 refers to the CAS latency, indicating the delay between a memory request and data availability. CL21 is typical for this speed and memory type, balancing performance and stability. Can this memory module be mixed with non-ECC memory? Mixing ECC and non-ECC memory is generally not supported in server environments, as ECC memory requires compatible systems to utilize error correction functions. Does the 128GB capacity refer to a single module size? Yes, the 128GB specification indicates the size of this single RDIMM memory module designed for high-capacity server installations.
