FAQ's
What does the 1Rx8 designation mean? The 1Rx8 indicates this module is single-rank with x8 DRAM chips. This describes the internal memory organization impacting compatibility and performance with certain server architectures. Is this module compatible with standard desktop motherboards? This module is an ECC Registered DIMM designed specifically for servers. It is not compatible with standard desktop motherboards that do not support registered ECC memory. What is the significance of ECC in this memory? ECC (Error-Correcting Code) allows the memory to detect and correct single-bit errors, enhancing data integrity which is essential for server and critical computing environments. What does CL52 latency indicate? CL52 refers to the CAS latency of the memory at 52 clock cycles, defining the delay between the memory controller requesting data and the module responding. Can this module be used in non-registered memory slots? No, this RDIMM requires a motherboard or server that supports registered memory modules. It is not usable in non-registered DIMM slots. What speed does DDR5-6400 represent? DDR5-6400 specifies the memory operates at 6400 MT/s (MegaTransfers per second), which relates to the maximum data transfer rate supported by the module.
